Researchers used neutrons to peer inside a working solid-state battery and discovered that its excellent performance results from an extremely thin layer, across which charged lithium atoms quickly flow as they move from anode to cathode and blend into a solid electrolyte.
Oak Ridge National Laboratory scientists found that a small tweak created big performance improvements in a type of solid-state battery, a technology considered vital to broader electric vehicle adoption.
Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long lasting, and energy dense. It holds promise for a wide range of applications from grid storage to electric vehicles.
All-solid-state lithium batteries have the potential to provide increased energy and power density compared to conventional lithium-ion batteries with a liquid electrolyte. The charge transport within solid electrolyte-based composite cathodes determines the C-rate capability and ultimately the overall performance of…
Since 2011, Nikhilendra (Nik) Singh has been a senior scientist in the Materials Research Department at the Toyota Research Institute of North America. His quest to find alternatives to lithium-ion batteries has brought him to Brookhaven Lab’s Center for Functional Nanomaterials (CFN).
