Researchers at the Samsung Advanced Institute of Technology (SAIT) in London and Samsung Research Institute in Japan (SRJ) introduced fully solid-state batteries with a long battery life. Fully solid-state batteries compare favorably with lithium-ion ones. how do they increase the amount of stored energy per unit mass. This allows you to create batteries of higher capacity, using solid electrolytes, which are safer than liquid. But there is a problem: lithium anodes can cause the growth of dendrites (needle-like crystals that can form on the anode of a battery during its recharging), which leads to a decrease in battery life and a decrease in its safety.
To solve the problem, scientists first proposed using a composite layer of silver and carbon (Ag-C) as the anode. This has increased the capacity, service life and overall safety of the prototype solid state battery. In addition, the prototype turned out to be approximately 50% smaller in volume of a lithium-ion battery of the same capacity. Similar technologies will contribute to the further development of electric transport. As expected, the appropriate batteries will allow electric vehicles to travel up to 800 km without recharging, and the battery will have more than 1000 charge / discharge cycles.
