Researchers demystify polymer binders to pave way for better sulfide solid-state electrolyte membranes

Using a polymer to make a strong yet springy thin film, scientists led by the Department of Energy’s Oak Ridge National Laboratory are speeding the arrival of next-generation solid-state batteries. This effort advances the development of electric vehicle power enabled by flexible, durable sheets of solid-state electrolytes.

The First Universal Principles for Designing Solid-state Batteries Developed by Korean Researchers

A Korean research team has presented the first universal design principles for solid-state batteries, signaling a paradigm shift in battery design research that previously lacked standard benchmarks. By applying the design principles, a 310Wh/kg-class pouch cell was produced and obtained third-party certification.

Neutrons look inside working solid-state battery to discover its key to success

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.

A new solid-state battery surprises the researchers who created it

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.

Editors’ Choice—Quantifying the Impact of Charge Transport Bottlenecks in Composite Cathodes of All-Solid-State Batteries

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…
