Samsung Advanced Research Institute and Samsung Japan Research Institute jointly released the latest progress of solid-state batteries.
This kind of high-performance and long-lasting all-solid-state battery has a higher energy density than lithium-ion batteries, which brings possibilities for greater capacity and is safer.
Previously, all-solid-state batteries used lithium metal as the anode. However, a prolonged period of time could easily lead to a branching effect and affect life and safety. This time, Samsung researchers explored a silver-carbon (Ag-C) nanocomposite anode layer, which also achieved greater capacity, cycle life, and safety.
It is reported that the thickness of the silver-carbon compound layer is only 5 micrometers, but the energy density of the battery is increased to 900Wh / L. The prototype battery is 50% smaller than a conventional lithium-ion battery of the same capacity.
Samsung's expectation for all-solid-state batteries is to be the first to be used in the field of electric vehicles. The prototype product can reach 800 kilometers on a single charge and the number of cycles can be as high as 1,000.
