Where will the future of battery technology go?

After entering the 21st century, many countries have begun to formulate mid- and long-term solar development plans, such as the National Photovoltaic Plan, Japan’s Sunshine Plan, and my country’s Western Provinces and Regions Electricity-free Township Plan. Solar energy application technology will start from monocrystalline silicon, devices, and thin films. The five fields of photovoltaic technology, PVMaT, photovoltaic modules and system performance and engineering, photovoltaic applications and market development have gradually deepened. For this reason, solar cell technology has also made great progress. It is integrated with the progress of silicon solar cells. It is divided into three types: monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells. The technology is mature, but due to the high cost and price of monocrystalline silicon, it will gradually be replaced by polycrystalline silicon thin film solar cells. However, amorphous silicon thin film solar cells are promising. Second, nanocrystalline solar cells are gradually entering people’s field of vision. Very low production cost and simple process, but stable performance can be obtained, and the production cost is only 1/5 to 1/10 of that of silicon solar cells. The life span can reach more than 20 years. With the emergence of power lithium batteries, new energy clean energy is the general trend, and battery technology is developing in the direction of new materials and clean energy, and major breakthroughs have also been made, but there are few commercial applications. The important reason is that it cannot achieve low cost. And the promise of multi-capacity. Therefore, the current research on electric vehicle batteries is still focused on lithium-ion batteries, followed by lead-acid batteries, nickel-hydrogen batteries and sodium batteries, ranking the top two in the number of patent applications for electric vehicle batteries and their management systems . In particular, the close cooperation between Tesla and Panasonic did not deliberately change the battery material, that is, the lithium-ion battery is still used. Only by improving the efficiency and improving the processing, the battery can be optimized according to the needs of the car. This shows that the manufacturing industry and The close integration of engineering technology is an available way for the commercial application of battery technology. However, the room for advancement of lithium-ion batteries is limited, and the processing costs are also high. The use and recycling of lithium-ion batteries will bring environmental pollution, and the uneven distribution of lithium-ion mines, such as lithium-ion batteries used in electric vehicles, will still occur Subject to the situation of lithium-ion-producing countries, this is exactly the same as the status quo of fuel vehicles. Therefore, according to industry insiders, in the future, electric vehicle batteries still have to develop in the direction of new materials and clean energy, such as solar, wind, hydro, silicon, nanocrystalline, etc., which will solve the high cost of batteries, environmental pollution and energy once and for all. The best way to crisis. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
