Mobile phone battery has become the future development of mobile communications “bottleneck”
Are here to participate in “2005 Global Mobile Communications Conference” An expert said that the mobile terminal battery technology has seriously lagged behind the cell phone terminal communications technology, the development of future mobile communications serious “bottleneck.”
Experts said the impact of mobile communication technology is currently the most important two factors First, the spectrum, and the other is the battery. Now, the former research currently
Great progress, but battery technology is very backward, and cell phone dell inspiron 1501 battery,dell inspiron 1520 battery technology and the development of communication technology terminal gap is 20% to an annual rate of 30% further opened.
In addition, as a result of the use of mobile phones faster and faster processors, more memory, plus a number of communication terminals are closed structure, there will be more of a local multi-mode, the increase in battery mode card will increase energy consumption, Therefore the development of battery technology has become the development of mobile communication technology, one of the biggest bottlenecks. At the same time, with the growing business of wireless applications, mobile phones are an annual electricity consumption increasing at a rate of 30 percent, if there is no breakthrough in battery technology, many 3G terminals will be the loss of business application infrastructure, mobile communications industries are being challenged.
The expert concluded that there is no good if the battery technology, the future of the 3G business can only be a more extensive personal communications vehicle, communications experts and described by many operators of wireless mobile services attractive only in the car achieved.
China’s potential hazards of waste batteries can not be ignored
Faced with the increasing of used batteries, some experts speak out: China’s potential hazards of waste batteries can not be ignored, the whole society need to arouse widespread attention and concern.
Now people in social life can not be separated from the battery is almost one day. According to China’s annual consumption of battery -80 100000000 7000000000, the per capita consumption year battery 5-6. Battery is most commonly used pagers, cell phones, pocket radios, portable music players, such as remote control.
Batteries to deal with pollution and its society has become concerned about the focus of environmental protection. State Environmental Protection Administration of the Technology Standards Department that, with the battery type, production and use continues to expand, the number of used batteries and types are also increasing. Used batteries contain mercury, lead, cadmium, nickel and other heavy metals and acid, alkali, such as electrolyte solution, and the ecological environment on the human body have different degrees of harm. It is understood that the one on human health and ecological environment is more harmful, hazardous waste control included in the list of batteries are: mercury batteries, the battery is; lead-acid battery; cadmium batteries, nickel-cadmium dell inspiron 1501 battery,dell inspiron 1520 battery mainly.
Experts told the reporter, even though some of our large-scale battery manufacturers have begun production of mercury-free batteries, but still a large number of small and medium-sized production is mercury batteries, because of their prices, the application of a wide range of significant sales. The main application of lead-acid batteries in the automotive, electric bicycle, communications standby power and emergency power supply and so on. And nickel-cadmium batteries are commonly used in mobile phones, power tools, electric toys, etc., is a rechargeable battery.
Relevant data show that a bad battery in place on the 1st, the one square meters of soil would have lost the use of permanent value; a button battery 600 tons of water can be contaminated, a person’s life is equivalent to the amount of drinking water. The greatest threat to the natural environment in several substances, the battery contains mercury, lead, cadmium, etc., if used batteries into landfill with domestic garbage or abandoned, leaking mercury and heavy metals will infiltration in the soil, polluting groundwater, and then into the fish, crops, the destruction of the human living environment, and indirectly a threat to human health.
Once the absorption of these heavy metals in the body after which the disease does occur? According to experts, mercury is a highly toxic heavy metals, of great destructive power of the human central nervous system, the fifties of the last century occurred in Japan shocked the world as a result of Minamata disease is caused by mercury pollution. Currently, China’s production of alkaline batteries containing mercury content of 1% -5% of the mercury content in batteries neutral to 0.025%, China’s consumption of mercury in battery production of dozens of tonnes each year by as much as on. Cadmium in the human body can easily cause chronic poisoning, the main disease is emphysema, bone softening, anemia, is likely to paralyze the body. The human body and lead the most difficult to discharge, which interfere with renal function, reproductive function.
The United States and the world’s leading R & D, Professor of Chinese high-performance plastic solar cells (Figure)
University of California at Los Angeles (UCLA) School of Engineering and Applied Science Department of Materials Science and Chinese Professor Yang Yang, and lead his research assistants and graduate students, after 5 years of research, invention of a high-efficiency plastic solar cells dell inspiron 1521 battery. U.S. materials research of the most authoritative journal of the “natural materials”, published on the 10th the results of their research, their research affirmed the leading position in the world.
According to the United States, “World News” report, said Yang Yang to accept, more recently, the United States, crude oil and gasoline prices have been hovering in the high price to find the updated alternative energy, energy has once again become the most popular materials sector. Solar energy has been seen as a popular alternative energy sources. However, the absorption of solar energy cost template, is the traditional three to four times the fuel, resulting in the promotion are subject to certain restrictions.
Yang Yang said that the use of plastic so the concept of solar cells, derived from a student. Before the general understanding of the plastic through the diode current will be coupled with light-emitting. Five years ago, his students thinking in the reverse direction, to try whether the light playing on the plastic, to generate electricity.
Yang Yang said that his research team studied the current out of the plastic solar cell, could reach 4.4 percent of the power generation efficiency, and non-crystal silicon cells is similar. That is, if the photon into the 100, will produce 4.4 electronic. Counterparts around the world study the same material, only 1% point more than efficiency dell inspiron 1521 battery. Therefore, the results of their research leading substantially.
Yang Yang said that the study of the market as a business, needs to be three to five years, but his research team will work hard to help manufacturers to commercialize research findings.
