CPPCC National Committee members suggested that standardization of mobile phone batteries as soon as possible
In recent years, mobile phone ownership is Digital Camcorder Battery growing very rapidly in China. According to incomplete statistics, at present owned by the nationals have been more than 400 million mobile phones. In bringing communications facilities, while the negative effects of mobile phones has become more prominent, especially in the environmental hazards caused by mobile phone batteries staggering.
Zhu Jianguo in Shanghai CPPCC National Committee members learned in the investigation, at present in the city every family used at least 45 mobile phones, and most of them are “double-double charge” (two batteries, two chargers). As a result, each household will have mobile phone batteries 10. To the country 400 million mobile phone ownership basis, the stock of mobile phone battery is enormous.
The standard deviation varying compatibility
Zhu Jianguo mobile phone batteries “soaring” and blamed the cell phone battery standards are not unified, poor compatibility. Of different brands of mobile phone batteries used in the size, shape are different, and even the same brand will be different models of mobile phones use different batteries. In this way, consumers only buy the same brand same model phone, the original battery in order to continue to maintain “viable.” Once the change to other brands or models, it can only be an old battery into the “Lenggong” the.
Mobile phone battery standards are not uniform and give consumers an economic burden. Handset makers can not be according to uniform standards for the production or procurement of cells, raising the cost. This part of the cost will eventually be “passed on” to the Digital Camera Battery consumer.
There are precedents of ordinary batteries
What has caused the phone battery standards, specifications are not uniform? ZHU Jian-guo think that the fundamental reason is that profit-driven. “Battery Standard non-uniform, increasing business costs, but also gives businesses an attractive profit margins.” He said, from a technical point of view, to a unified standard mobile phone battery is not difficult. Inside the phone setting a unified standard cell phone battery will not affect the appearance, just like all kinds of electrical appliances while using the same common batteries, can design a distinctive look and feel of the product shape.
Zhu Jianguo in the proposal calls for national authorities as soon as possible to develop a unified standard mobile phone batteries, making it like a normal battery as a universal, can set up several kinds of specifications to enable mobile phone manufacturers according to their own products, the need to choose. Mobile phone battery can be reduced so harmful to the environment and waste of resources, but also reduce the financial burden of consumers.
ZHU Jian-guo believe that Shanghai has developed the mobile phone market, also has a higher level of battery production enterprises and scientific research units, is perfectly placed in the implementation of uniform standards for mobile phone batteries one step ahead.
Environment protection and energy batteries alkaline Canon Battery hit the market setback in China’s cover only the
In response to the national energy-saving and environmental protection policy appeals, a number of manufacturing industries in transition, produce high-quality environmentally friendly energy-saving products, but those products are currently facing market, torture, to promote the situation is not optimistic. Among them, the battery industry, the market faces an embarrassing is particularly prominent.
In 1997, the former China Light Industry Association, the State Environmental Protection Administration and other 9 departments have jointly issued a “battery products on the limited amount of the provisions of mercury,” demanding since January 1, 2001, the ban of mercury in the domestic production of all kinds of great battery weight of 0.025% of the battery. Since January 1, 2005, the ban on domestic production of mercury batteries is greater than the weight of 0.0001% of the alkaline zinc-manganese batteries (not mercury content of less than 2% of the alkaline manganese and silver oxide button batteries). Is aimed at policy “baton,” the first source in the production of a high standard, thereby bringing about market consumption, thus speeding up the process of the popularization of environmentally friendly energy-saving battery.
This provision has been enacted almost 10 years now, however, as the mainstream products in environment protection and energy battery – alkaline batteries in China’s cover only 20% of the battery products, which not only in developed countries 80% ~ 90% of the high popularity of rate far away from the national “Tenth Five-Year Plan” 30% of the goals there is great distance. Western developed countries has largely achieved the energy-saving environmental alkaline battery production to consumption, the transition, but in China’s markets, the majority of consumers apparently do not ignite consumer passion for alkaline batteries.
Policies to guide the battery cell production, while energy-saving environmental protection, the relevant state departments and industry associations are also actively doing business Tuiyou limit inferior work, and strive for environmental protection to create a good energy-saving battery consumption environment. Since August last year, started by the National Light Industry Quality Supervision and Test Center battery-specific testing, Nanfu, 555 and 11 backbone enterprises of mercury in alkaline manganese batteries are lower than the mercury content of mercury-free battery-limited targets, in full compliance with the provisions of the State Department 9 ; China Canon BP-208 Battery Industry Association, the 11 brands of alkaline manganese battery identified as the first “green alkaline manganese battery products,” recommended to the public. However, despite the relevant national departments and manufacturers to work together, environmental protection and popularization of energy-saving battery, or so slow the pace. Many in the industry say there is a big market spending is the crux.
In the vast majority of consumers in the eyes, the battery life is just the role of ordinary consumer goods, and soap, toothbrushes little different. Consumers will not spend too much buying batteries thoughts. In addition, the alkaline battery prices higher than the ordinary carbon-zinc batteries some, many consumers feel that carbon-zinc batteries cheaper and affordable, especially in rural areas in the country a broader market, the level of consumption is still relatively low, so the consumption of the carbon-zinc batteries more directly that the consumption of alkaline batteries is a waste.
Experts pointed out that this idea is a consumer misunderstanding. From the consumer sense, energy-saving environmental protection despite the higher price of the battery, but it reflected energy-saving, environmental protection targets are ordinary carbon-zinc batteries several times. The south of Fu battery, for example, from the electricity index point of view, a Nanfu alkaline battery power is the same size carbon-zinc batteries of six times; from the environmental indicators point of view, Nanfu alkaline batteries almost without causing any pollution can be discarded along with the garbage; from life indicators point of view, the life of ordinary carbon-zinc batteries is 6 months, the battery can keep the original power capacity of 70%, alkaline Canon BP-511 battery shelf life is 3 years, 3 years, Nanfu Battery the electric capacity and 90%; from a social sense, the alkaline batteries used in the production of materials, more energy saving society. Because they do not use of natural manganese ore, manganese dioxide, its use can be used, or other low-grade manganese carbonate manganese ore for processing, so there is no shortage of resources. The carbon-zinc batteries are the main component of natural manganese, manganese ore, but my discharge fewer resources, due to years of over-exploitation, the availability of discharge manganese nearly depleted.
Experts say consumers can produce quite a big stir in the battery recycling issue. Whether in the district, school or government organizations and institutions, there will be a lot of recycling the battery box. Carbon-zinc batteries in the general popularity of the times, when people see that after the recovery of the battery box will naturally think of things that the battery is not environmental protection, it should be put boxes for centralized treatment. Such civil actions to achieve a good recovery performance. In the environment protection and energy the battery will become the mainstream of the times, if we can learn from this way of thinking, to guide people in popular awareness and consumption of alkaline batteries, they will certainly speed up the process of the popularization of environmentally friendly energy-saving battery.
Information Week: The battery’s future
In mobile technology, we always never-ending technological advances as a birthright. For notebook computers, music players, handheld computers (PDA) and mobile phones, the constant “downsizing” is a must, at the same time, but also add features to enhance speed, extended memory. However, there is one thing dragged on for legs – that is the battery.
Recently, the high incidence of notebook computers fire accidents, so that the battery has aroused great concern of all parties. Incident was Sony Corporation (Sony, hereinafter referred to as Sony) in the production process problems caused by more than 600 million batteries were Canon LP-E5 recalled. When the incident became clear, people still need to face the undeniable fact – the battery power issue is still firmly tied us, the digital operation or the capacity of the game and thus be greatly limited. Even more unfortunately, in recent years this situation has not changed much. Battery power, compared with the needs of users, but also far apart, and the lack of a major breakthrough – despite the battery capacity of these devices than ever before have some improvement.
Mobile device battery is a need to overcome the technical fields. Therefore, some experts believe that, consumer electronics, notebook computer and communications industries should be from the existing battery out of the conceptual framework, the use of new alternative technologies to give portable mobile device. Some of their ideas is indeed good to be true. For example, to a mobile phone loaded block hydrogen fuel cells, another example for BlackBerry (BlackBerry) PDA to install a small gas turbine engines. These concepts are ahead, but it had to recharge every few hours to shake off the shackles of conduct like this bold experiment is necessary.
Turbine engine on a chip
Massachusetts Institute of Technology (MIT) researchers are testing, by means of micro-electrical mechanical system in the continuous development of power sector, in the coin-sized silicon chip establishment of micro-gas turbine engine. Continuous supply of such devices compared to the same time, the weight of the battery 10 times longer, so developers created a smaller generators. The micro-processing engine model consists of six silicon wafers bonded together, of which compressor, combustor, rotating turbines and other necessary functional modules have been cured in a separate silicon layer. Fuel and air mixture in a tiny combustion chamber and burned. Micro-turbineCanon NB-1LH blades made of material per second transfer rate of 20000 high-speed rotation.
“We have confirmed that all components can work properly.” Professor in the Department of Aeronautics and Astronautics Massachusetts Institute of Technology Allen • Epstein (Alan Epstein) said, “Now the challenge is to make them work together, and that the integration of group together. “Epstein predicts that this generation model can be displayed within a year. To put into commercial use, however, then it had to spend three or more years time.
Even if the power supply to be perfect, it must cross the barrier in front of the battery replacement technology barriers. If it is the price of the battery so cheap as now, it can achieve an annual output of hundreds of millions of batteries do? People would be willing to surmise in a pocket or purse inside a combustion engine do?
Hydrogen fuel cell is about the birth of another alternative. Arizona State University (Arizona State University) chemist Church • (Don Gervasio) are working on a hydrogen fuel cell, which uses the concentration of 30% of the mixture of borohydride solution to produce than the same volume of solution – a more advanced hydrogen-rich hydrogen. He explained that such boron hydride solution than conventional fuel cells more stable and more secure.
“We are creating a boron hydride container, on the inside even if lighting a match can also be easily extinguished.”Said. We can see that he is very concerned about this that any new power supply will be faced with security problems. Solution flowing through the element made of laptop batteries ruthenium catalyst to release hydrogen, and then through a layer of film, with the fuel cells combine oxygen to produce electricity.
This approach must have to overcome some obstacles. In R & D initially, as the reaction produced a by-product can not be dissolved, resulting in oxygen electrolyzer being blocked, research once frustrated. R & D team was the use of ethylene glycol (an antifreeze) to dissolve boron oxide, without affecting the oxygen generation. Explained that he led the team again to 1 ~ 3 years time can develop a prototype of industrial products, but the commercial product will have to be able to come out a few years.
Other companies also continue to explore an alternative to liquid methanol fuel cells, but there is no where near the success of a development. Because it has to meet three conditions: laptop battery to meet the demand, the volume should be small enough to be able to insert the laptop battery slot small space, while manufacturing costs but also, and now the laptop battery close.
Limited choice
Lithium-ion batteries since the 90 years since the last century, replaced nickel-metal hydride batteries, the late 90s and gradually notebook computers and handheld devices become the mainstream configurations. Mainly because in the same size, the lithium-ion can store more power, but also far more portable than the nickel-metal hydride materials. Over the past few years, lithium-ion technology in energy density has increased by 20% ~ 30%. According to the Portable Rechargeable Battery Association (Portable Rechargeable Battery Association) data, are now common in general to achieve the laptop battery power supply 4 to 5 hours, while in 2004 only to maintain 3 hours. Currently the world’s lithium-ion batteries produced each year there are about 2 billion.
Most lithium-ion batteries are based on cobalt oxide inside the very basis of the negative. Because it contains oxygen in the material, it is extremely unstable. If the production of lithium-ion slightly careless, you may have short-circuit or overheating, and in some occasions, the battery inside the electrolyzer could spark a fire. Most major notebook manufacturers have been recalls of Sony-manufactured batteries, battery replacement product research and development on the news reports continued to hit the newspapers, but also let the little there are concerns that the industry became a focus of media attention.
The good news is, the problem appears confined to the Dell Battery. The battery industry, most people also believe that the company has the ability, and certainly this important process can solve the problem. Sony said it has taken measures to prevent the problem arises again.
The bad news is, it seems we have to continue to suffer from the status quo of this technology. Frost & Sullivan Inc. analyst Sarah • Bradford (Sara Bradford) in a recent report claimed that lithium-ion battery energy density has been close to its theoretical limit. While the new alternative to the possibility of the recent market has little in the short term could only expect a slight improvement. “In the future two or three years and did not really much has changed.” Intel Corporation (Intel, hereinafter referred to as Intel’s) senior vice president and general manager of Mobile Business Unit Pu David (David Perlmutter), said, “Now the industry is focused mainly on the , how to improve the conventional lithium-ion battery manufacturing process and improve the reliability of the battery. ”
But there are many start-up companies and academic research institutions, is conducting a relentless effort to make plans for the portable power supply projects, building blocks. (Sony declined to discuss it has already carried out in the next generation of battery R & D work.) Battery(75uyf, C1295, GD761) testing and development of alternative technologies is accelerating among the many groups are actively seeking funding, find partners and mining-related clients.
