What are the future development directions of lithium-air batteries?

There are actually many star-level existences in the field of lithium batteries, and all-solid-state lithium batteries and lithium-air batteries are among the best. 1. All-solid-state lithium batteries The next generation of lithium batteries should be all-solid-state lithium batteries. Professor He quoted Academician Chen Liquan of the Chinese Academy of Engineering at OFweek2015 my country’s Lithium Battery Technology Industry Seminar. Timing of development. Lithium-sulfur and lithium-air batteries have become research hotspots, but their industrialization is relatively difficult. In fact, if the industry overcomes the problem of all-solid-state lithium batteries, and then makes lithium-sulfur and lithium-air batteries, related technical problems will be easily solved. All-solid-state lithium battery is a kind of lithium battery that uses solid electrodes and solid electrolyte. Solid-state batteries generally have low power density and high energy density. Because of the relatively high power and weight of solid-state batteries, it is an ideal battery for electric vehicles. In addition to its safety superior to traditional lithium batteries, all-solid-state lithium batteries have a great advantage, that is, the charging and discharging cycle life is very long, up to 45,000 times, and 95% of the initial capacity is preserved. This allows other The types of batteries are unmatched. 2. Lithium-air battery The advantage of lithium-air battery lies in its huge theoretical energy storage capacity. It is by far the energy storage device with the largest energy density, which is equivalent to gasoline. In this way, all-solid-state lithium batteries may be commercially available much earlier than lithium-air batteries. Professor He believes that in view of the existing problems, the future research directions of lithium-air batteries are as follows: 1) Continue to develop a more stable electrolyte system to reduce the accumulation of by-products caused by electrolyte decomposition; at the same time, electrolyte additives will become a stable system and improve Effective methods for performance. 2) Continue to deeply understand the reaction mechanism of lithium-air batteries. This is a good guide for how to choose the electrolyte system and the positive/negative electrode materials. 3) Research and improve lithium-air battery cathode materials, further reduce the overvoltage platform, and improve the charging and discharging efficiency. This is an important factor in the promotion of lithium-air batteries to market applications. 4) Research on new anode materials for lithium-air batteries to improve battery safety and stability.
