Samsung has revealed a prototype solid-state battery that boasts an energy density up to 900Wh/L at around 50% smaller by volume than a conventional lithium-ion battery.
The prototype pouch cell would enable an EV to travel up to 800km on a single charge, and features a cycle life of more than 1,000 charges.
Researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) presented their findings to scientific journal Nature Energy on 9 March.
Measuring 5µm (micrometers) thick, the silver-carbon (Ag-C) nanocomposite layer allowed the team to reduce the cell’s anode thickness and increase energy density.
The team found that using Ag-C composite layer as the anode enabled the battery to support a larger capacity, a longer cycle life, and enhanced its overall safety.
Dongmin Im, master at SAIT’s Next Generation Battery Lab and the leader of the project, said: “The product of this study could be a seed technology for safer, high-performance batteries of the future.”
