Solid-state batteries have become the development direction of electric vehicle battery technology in the future

In recent years, major global car companies and accessories companies have been striving to seek breakthroughs
in battery chemistry and energy density.
A few days ago, Bosch announced that it plans to launch a new solid-state battery for electric vehicles by 2020, which can double the range of electric vehicles and halve the cost
.

Scientists vividly describe the traditional liquid lithium battery as a "rocking chair battery", lithium ions run back and forth at both ends of the rocking chair, and in the process from positive electrode to negative electrode to positive electrode, the battery completes the charging and discharging process
.
The principle of solid-state batteries is the same
.
The density and structure of a solid-state electrolyte allows more charged ions to gather at one end, conduct more current, and increase battery capacity
.

It is understood that under the same power, the volume of solid-state batteries will be smaller
.
Because solid-state batteries do not have a liquid electrolyte, storage will be easier, and when used in automobiles, there is no need for additional cooling devices and electronic controls, which effectively reduces weight
.
Solid-state batteries have another advantage, which is that they are less prone to explosion or fire
in an accident.
Due to the good characteristics of solid-state batteries, it is currently an ideal battery
for electric vehicles.
