Where will the future of batteries go?

After entering the 21st century, many countries have begun to formulate medium-and long-term solar energy development plans, such as the U.S. national photo voltaic plan, Japan's sunshine plan, and China's western provinces and autonomous regions without electricity and power. Solar energy applications will gradually deepen into five areas: Mono crystalline silicon and advanced devices, thin film photo voltaic technology, PV MaT, photo voltaic components, and system performance and engineering, photo voltaic applications, and market development.

To this end, solar cell technology has also made great progress. One of them is reflected in the progress of Silicon solar cells. It is divided into three types: Mono crystalline Silicon solar cells, poly silicon thin-film solar cells, and amorphous silicon thin-film solar cells. The most mature solar technology, but due to the high cost of mono crystalline Silicon, It will gradually be replaced by poly silicon thin-film solar cells, but the most promising is amorphous silicon thin-film solar cells; Second, nanocrystalline solar cells are gradually entering people's horizons. It can harvest stable performance with very low production costs and simple processes. Its production cost is only 1/5 to 1/10. life of Silicon solar cells can reach more than 20 years.

With the advent of power cells, new energy cleaning can become the general trend. Battery technology is developing in the direction of new materials and clean energy. It has also made major breakthroughs, but there are few commercial applications. The main reason is that it can not meet the low cost and multi-capacity commitments. Therefore, the current research on batteries for electric vehicles is still concentrated in lithium batteries, followed by lead-acid batteries, nickel-metal hydride batteries and sodium batteries. Japan and the United States have the world's top two patent applications for batteries for electric vehicles and their management systems.

In particular, the close cooperation between Tesla and Panasonic did not deliberately change the battery material, that is, the lithium battery was still used. By simply improving efficiency and improving production, the battery could be optimized according to the needs of the car. This shows that the manufacturing industry and Engineering technology is closely integrated, It is an available way to promote the commercial application of battery technology. However, the progress of lithium batteries is limited and the production costs are very high. The use and recycling of lithium batteries will bring about certain environmental pollution. In addition, lithium mines are unevenly distributed throughout the world. For example, lithium batteries are used in electric vehicles, and they will still appear to be subject to lithium production. country situation, This is similar to the status quo of fuel trucks.

Therefore, according to industry sources, batteries for electric vehicles in the future still need to develop in the direction of new materials and clean energy, such as solar energy, wind energy, hydro energy, Silicon materials, nanocrystals, etc., is the best way to solve the high cost of batteries, environmental pollution and energy crisis once and for all.
