The global science and technology reported on March 30 Reporter on heart ¡¿ the life of electronic product is always a big problem which restrict the development of the industry. Whether mobile phones or electric cars, currently used in lithium ion battery manufacturing this high, life is short, always affect the user experience. Nowadays, the phenomenon is expected to change thoroughly, because the first new type of double ion battery technology in shenzhen was born!
Yesterday, reporters learned from shenzhen institute of advanced technology, Chinese academy of sciences, the institute Tang Yongbing researcher and his research team pioneering a new type of high energy density of aluminium - graphite double ion battery technology the latest achievements in international energy material top journals after the journal of advanced energy materials, scientific network by Germany last week "Wissenschaft aktuell" invitation. German science network reported that the technology will have a significant impact to the existing lithium electricity industry.
The portable electronic equipment, electric vehicles, renewable energy systems in areas such as the main energy conversion and storage devices are lithium ion batteries, but the commercial lithium ion battery energy density, low manufacturing cost is higher, and traditional lithium ion battery electrode materials containing toxic metals, battery waste can cause serious environmental problems. Especially the new energy automotive power battery industry demand, but at present, power battery technology is still stopped in front of the new energy vehicles development a ravine. If the lithium ion battery pack of electric vehicles, fuel cell powered electric vehicles, there are cost and the range of challenges.
According to the relevant person in charge of shenzhen advanced school of Chinese academy of sciences, Tang Yongbing team found that the new type of high energy density of aluminum - graphite double ion battery, is a new kind of highly efficient, low-cost energy storage battery. This new type of battery compared with the traditional lithium-ion battery technology, the battery has obvious advantages, not only decrease the production cost by 40% - 50%, at the same time improve the energy density of at least 1.3-2.0 times.
Preliminary estimates, 500 Kg weight of aluminum - graphite the range of the battery can reach about 550 kilometers. Compared with traditional lithium-ion battery technology, this kind of battery has obvious advantages, not only decrease the production cost by 40% to 40%, at the same time improve the energy density of at least 1.3-2.0 times.
It is understood that if a new double ion battery technology to realize industrialization, or will have a significant impact to the existing lithium electricity industry pattern, the future of mobile phones could be more frivolous, battery life is longer, the high cost of the electric car battery as well as the short range of key issues will be resolved. However, at present the battery technology also needs to be optimized, such as the need to further improve the cycle stability of the battery, etc.
