Future development direction of power battery technology

In the future, power battery technology will never stay at the level of existing lithium-ion batteries. When the demand for battery energy expands, it is still unavoidable that waste batteries will pollute the environment. How the future power battery technology develops is bound to More efficient, cleaner and more environmentally friendly. According to the currently known technology, it is theoretically feasible to solve the high cost of batteries and environmental pollution once and for all, but there is a long way to go to achieve full commercialization through technology; power lithium batteries The emergence of new energy clean energy is the general trend, battery technology is developing in the direction of new materials and clean energy, and major breakthroughs have been made, but there are few commercial applications. The important reason is that low-cost and multi-capacity cannot be realized. Commitment, therefore, the current research on batteries for electric vehicles 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 batteries and management systems for electric vehicles. Especially 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 efficiency and improving production, 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 production costs are also high. The use and recycling of lithium-ion batteries will bring environmental pollution. In addition, the uneven distribution of lithium mines, such as electric vehicles that use lithium-ion batteries, will still be restricted. In the case of lithium-producing countries, this is exactly the same as the status quo of fuel vehicles. After entering the 21st century, many countries have begun to formulate mid- and long-term solar energy 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 and devices, 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 current monocrystalline silicon 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; secondly, 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 its production cost is only 1/5 to 1/10 of that of silicon solar cells. The life span can reach more than 20 years. Therefore, according to industry insiders, in the future, batteries for electric vehicles still have to develop in the direction of new materials and clean energy, such as solar energy, wind energy, water energy, silicon materials, 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.
