Portable low-power chip to enable extended battery life 10 times

Nokia and the Massachusetts Institute of Technology Microsystems Science Laboratory researchers are developing related technologies, by reducing the operating voltage of the transistor chip to reduce power consumption. Their research will act as a catalyst may function to better meet the growing number of electronic products on the demand for energy consumption.
Nokia Research Center, said Hicks, director of Nokia in the development to the threshold voltage lower than the voltage of the chip operation has made great progress. Chip as the transistor is a switch, the voltage increases according to the difference in the "open", "off" state to switch. By reducing the voltage, the transistor will also reduce the size of opening, the current through the gate will also be reduced.
"Below the threshold" of the transistor chip power consumption can be reduced to one-tenth to one-fifth of normal Inspiron 2500 Battery levels. Hicks said that a lot of chip power consumption - such as mobile phone video compression chips, lower power consumption of electronic products will help extend the battery life of equipment, ranging from 3-10 times more often.
Nokia researchers are analyzing "below the threshold" of the applications of transistors, but the commercialization of these chips also need 4-5 years.

Expert: Li-ion battery technology itself, there are no problems

News September 6, according to foreign media reports, the lithium-ion battery industry experts said Steven Carlson, lithium-ion battery technology itself does not exist any fundamental error. The reason why the notebook battery frequently fire, its causes are manifold.
According to CRN website reported that following the recall of Dell and Apple have been hidden in large quantities there are the laptop battery fire, the Panasonic also announced this week 6000 notebook battery recall. Although the Panasonic is much smaller size of the recall, but the user touched the nerve of the tension.
In this regard, heat-resistant battery developers Optodot company CEO Steven Carlson said, with the users of battery life and safety of the increasing requirements, the battery manufacturers are facing the future will be even more serious security challenges.
Carlson said: "At present, lithium-ion battery technology itself does not exist any fundamental mistakes. The reason why some accidents occur mainly because of battery manufacturers due to the requirements of the standard."
Carlson said the lithium-ion batteries can not be the temperature reached 100 degrees Celsius, therefore, can use the "Auto-off" technology to prevent the battery caught fire. In addition, Optodot In addition the company has also developed a new isolation technique, the electrodes can be separated from the battery in order to avoid the battery caught fire.
Carlson believes that in order to create a higher quality battery, it is necessary to use better materials. At present, the battery manufacturers are facing the problem is, it is necessary to the security of the battery production, but also reduce costs. It is necessary to improve the life, but also lower the temperature.
Still, Carlson said that notebook sales will not be stalled due to the battery recall.

Scientists inspired by photosynthesis in the leaves to develop new solar cell

According to the Australian Broadcasting Corporation reported on the 4th, the Australian researchers said that mimic chlorophyll in plants to create synthetic molecules, which may one day be able to develop a highly efficient solar cells TravelMate C300 Battery.
From the University of Sydney, led by Professor Silei Molecular Electronics Research Group, recently held in Rome and the International porphyrin phthalocyanine dye of the General Assembly on the results of their research. Crossley said: "After millions of years of evolution, nature can be very effective to capture the light and put it into energy. We are trying to mimic the way natural photosynthesis."
Leaves the body with intensive use of the chlorophyll molecule to change light into electrical energy and then into chemical energy. Contributed to the function of chlorophyll essential element of the pigment porphyrin, which is located in the center of magnesium ions. Crossley and his research group has produced chlorophyll (in the photosynthesis in the primacy of living) of the synthetic form, it will be conversion of light energy into electrical energy. And the natural state, when these synthetic molecules are arranged in densely together, they will for concerted action and effective collection of solar photons. Crossley said: "there must be many of these synthetic molecules, because if there is only one molecule, and its role in efficiency is very low."
Researchers have created a football-shaped molecules of chlorophyll synthesis. It has a dendrimer scaffold, is a carbon, hydrogen, nitrogen, a high degree of synthetic polymer nano bifurcation. Adhesion molecules in the tree is on the capture of light pigment porphyrin synthetic version. A are known as "buckyballs," spherical carbon molecules located in between the porphyrin from the collected electronic absorption of solar photons.
Crossley and his research group has been the use of synthetic chlorophyll to build a prototype organic solar cells. It is based on a natural release, they want to eventually be able to produce than existing solar cells more efficient. Green leaves will be effective in 30% -40% of light energy into electrical energy, which is usually silicon-based solar cells will be effective only 12% of light energy into electrical energy.
Crossley said: "We already have a photovoltaic device or imitate the main component of solar cells. In the long run, we must try to produce as a thin layer of paint, the simple application on the roof things. "He said that the research team also hopes to create a storage device to replace the metal-based batteries.
Crossley said that A32-A8, when used to absorb sunlight when the molecule is not too big to be the most effective solar energy into electrical energy. The ideal diameter of this molecule is that it absorbed about half the wavelength of light, which he believes is the 300-800 nm visible light. Crossley said: "You can not be produced by the material is too dense, because that will not be able to light through it." He said that there are many scientific research organizations in the use of nanotechnology to create a more efficient solar cells. "It is a very hot topic," Crossley said, "so people do use a variety of novel nano-materials and methods, so that solar-based electricity production more efficient."

Japan plans to introduce laptop computers with uniform safety standards for lithium batteries

Recently, following the Sony laptop production of large-scale lithium batteries have been recalled after the incident, the battery manufacturers in Japan to prepare for the notebook computer lithium-ion battery with the development of a unified safety standards.
Reported that, including Sony Corporation, Sanyo Electric, Toshiba Battery Company, Matsushita Battery Industrial Company of Japan, including members of Battery Industry Association and the Japan Electronics and Information Technology Industries Association is the discussion on specific criteria, the parties have basically reached a consensus.
Japanese laptop manufacturers use lithium batteries about 70% of the global market, manufacturers generally set their own safety standards. Is expected to draw up a new industry standard will include a battery of memory to allow the metal particles in the largest number and size, as well as battery charge control in the mode of voltage fluctuation.

Application of solar energy industry in Guangdong Li forefront again

High-purity silicon technology will be the most popular venture capital - ThinkPad T42 Battery, ThinkPad T42P Battery

Yangtze River Delta is now a new energy development in our country the best, but over the years has been engaged in solar energy research institute of Sun Yat-sen University, Shen-hui said that in Guangdong Province in 2003, before the solar energy industry at the forefront of the country, even though the solar Shenzhen applications are still leading the country, Guangdong reason, conditions and foundation for the emergence of a "Suntech."

PRD enterprises to the development of core technology

Shen-hui said that the Pearl River Delta in 2003, many enterprises to enter the solar industry, production, such as solar lawn lamp, solar flashlight, solar mobile phone charger and other products processing and export-oriented. Guangdong's solar PV products for the private enterprises, relying entirely on its own strength in this emerging field has developed a little bit. However, private enterprises in Guangdong has been engaged in product processing, not to the upper reaches of the development of solar energy has yet to grasp the core of electro-optic technology, enterprise development was also limited. Later, the Yangtze River Delta in support of the local government, the rapid development of solar PV industry, solar PV is now a national technology and industrial scale of the region's leading. Several cities in the Yangtze River Delta has an annual output of 20 megawatts of battery factory, and Guangdong does not have a 20-megawatt battery factory.

It is understood that Suntech has been interested in the development of Guangdong. Hui Shen believes that solar energy and other new energy enterprises, the export can not be used as the only access road, we must consider the domestic market. Guangdong is a consumer market that can not be ignored and export base. If the Guangdong local enterprises do not take this market, foreign companies will come.

From the National, the solar energy industry also has just begun, Guangdong has been leading, and now is not too late to catch up, even though the Shenzhen-volt solar power applications are still at the forefront of the country. In his view, Guangdong reason, conditions and foundation for the emergence of a "Suntech." However, as the emerging industries, government support is essential that the Government should take the lead in application to help businesses expand their markets. Unfortunately, up to now, Guangdong has not the policy of supporting solar energy industry.

Silicon technology is the industry

How to seize the industry Shen-hui said that China's solar PV industry, the main technical problem is silicon materials, who can break through the bottleneck of the future, who may become the future "Suntech." High-purity silicon material technology is the technology of solar energy industry chain in the highest, the United States, Germany and other countries in the monopoly market, China does not master this technology. However, China's resource-rich silicon, is the export of low-purity silicon power, solar power constraints factor is the industry's largest raw materials, so there "There is a silicon-King" is. If the business foresight to enter the technology field ThinkPad T43 Battery, ThinkPad T43P Battery, will be very promising. This venture will also be the best place for investment.

Analysys analysis:

Consumer electronics from the current market situation, the various manufacturers products in the show, chip design, new features, etc. to increase gradually to narrow the gap. Some of the original can be greatly attract consumers to the features of the technology or consumer demand has been met, the compact size of the growing mobile needs of the growing consumer electronics market, the battery life has become a bottleneck of new features .

By the greatest impact on battery performance products, including notebook computers, digital cameras, portable DVD players and MP4 music players and mobile TV functionality to achieve and so on, standby time and use the key to stability is the result of two-speed.

Analysys International believes that the basic functions and additional functions, the current wide range of consumer electronic products have to meet a certain extent, the existing users. In this basis, to meet the continuing use of these features of the importance of batteries have become increasingly prominent. Analysys International predicts a period of time in the future, the consumer electronics in the function of the speed of technology upgrade would slow down, manufacturers will be the focus of competition shifted from function to maintain the basic operation of the ThinkPad T60 Battery, ThinkPad T60p Battery. Only the stability of the battery and the use of time to reach a certain level, the development of new features in order to have a new space for development.

Analysys perspective:

It is "easy to view - consumer electronics" that the consumer electronic products using the existing functionality has reached the current level of battery technology limits, in the new product before the battery, consumer electronics products in the function of the speed of technology upgrade would slow down .
