What is the future of all-solid-state lithium batteries

At present, the development of new energy vehicles has clearly risen to the national strategic level. Among them, the power lithium-ion battery is the most critical core component of new energy vehicles, and its criticality can be seen. Under the guidance of national policies, a global all-solid-state lithium secondary battery technology competition has begun. It is expected that hybrid solid-liquid lithium secondary batteries are expected to enter the terminal market first in 2020, and all-solid-state lithium secondary batteries will begin to enter in 2022. The terminal market, with the improvement of comprehensive technical indicators such as cycleability, rate, high and low temperature, and safety, gradually enters the electric vehicle market, and the flock of research institutions and company alliances may launch all-solid-state lithium secondary batteries Advance the time. It is precisely the breakthrough and practice of lithium batteries in the use of power, especially the promotion and use of new energy vehicles. Taking the domestic market as an example, 2016 was the year with the fastest growth in new energy vehicle sales, and the annual growth rate reached 84%, as lithium batteries are complementary products for electric vehicles, sales and industry scale have also increased. On the other hand, the use of lithium batteries in electronic products is becoming more and more widespread, constantly replacing other types of batteries. To sum it up, the development from liquid electrolyte to all-solid-state battery requires a process: the electrolyte content in the electrolyte will gradually decrease, and the gel electrolyte (such as PEO) system will gradually develop from the beginning to the semi-solid state, and finally transition to the real Of all solid-state batteries. In this process, the negative electrode materials used will continue to deepen, and the pre-lithiated negative electrode, and even the lithium metal negative electrode that has been explored by countless scientists for many years, will become our ultimate goal. In this process, the energy density of the battery can finally reach the vision of 350 or even 500 Wh/kg. All-solid-state battery technology is recognized as the next-generation innovative battery technology that is the key to development. Although there are still many factors restricting the use of Ah-level batteries or EVs, at least the future is bright at present, and I believe in the near future. The technology becomes more and more mature, and the problems can be solved easily. By that day, we may no longer have to worry about the current headache of battery safety detection failure.
