The core technology of electric vehicles is "three electrics", and "three electrics" is led by battery technology. Many car companies are in the main attack on the "heart" of the electric car problem, solid-state battery is considered to represent the future, but also one of the most difficult to overcome the technology. In this technology "Mount Everest", who will be the first to reach, so that the all-solid-state battery out of the laboratory and mass production on board, who will have the opportunity to get a rare entry volume in the second half of the electric car.

Difficulty of development is comparable to "Mount Everest".

The development of power battery technology is the global automotive industry electrification transformation of the technology high ground, and all-solid-state batteries are recognised as the next generation of batteries, become the next generation of battery technology competition key high ground.

In the view of Ouyang Minggao, academician of the Chinese Academy of Sciences, all-solid-state batteries have the potential for technological disruption. First of all, high security, sulfide solid-state electrolyte thermal stability can be maintained to 300 ° C, liquid electrolyte is 100 ° C to evaporate; Secondly, high energy density, all-solid-state batteries can be from the monomer and module can be improved in two aspects of the energy density; again is a high power characteristics, the liquid lithium-ion battery ion conduction is the mode of transport, that is, the ion is in the liquid electrolyte to move in a layman's terms! Need to "boat", but lithium ions in the solid-state electrolyte is a jump mode, resulting in a substantial increase in charging speed; by temperature adaptability, the existing liquid lithium-ion batteries in the low-temperature environment range is not ideal, and all-solid-state battery electrolyte in the range of -30 ° C and 100 ° C will not be solidified, will not be gasification. gasify, so it doesn't need very complicated thermal management and won't have a significant drop in capacity in winter; and lastly, there is a wider range of materials to choose from, as solid-state batteries have a wide electrochemical window.
