Researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) have made a breakthrough in solid-state batteries. Solid-state batteries provide greater energy density up to 900Wh/L and utilize solid electrolytes. The problem with solid-state batterie has been the lithium metal anodes frequently used are prone to the growth of dendrites. This reduces the battery’s life and safety.
To combat those effects the team, for the first time, used a silver-carbon (Ag-C) composite layer as the anode. By incorporating this Ag-C layer the researchers found that the prototype battery supported a larger capacity, a longer cycle life, and enhanced its overall safety.
This breakthrough opens up the possibility for long-range electric vehicles, off-grid electric systems for homes, and backup systems for various industries such as telecommunications.
