Lithium-Metal Battery Survives 1,000 Cycles, Powers LED Even when Cut

Researchers Develop New Composite Solid Electrolyte Enabling 1,000-Cycle Lithium-Metal Battery

Researchers at Chonnam National University in South Korea have developed a tri-layer composite solid electrolyte that could make lithium-metal batteries possible. The novel electrolyte, which was inspired by natural adhesive proteins mussels use to stick to rocks, improves ion transport and prevents dendrite formation. Lithium-metal batteries are one of the most promising battery technologies thanks to their high energy density and increa... (co…

Tri-layer electrolyte improves safety and lifespan of lithium-metal batteries

Lithium metal batteries (LMBs) that use pure lithium (Li) for their negative electrodes are attracting significant attention because of their extremely high theoretical capacity. However, their practical applications are limited by low cycling stability and safety issues arising from dendrite formation, electrolyte breakdown and uneven solid-electrolyte interface formation.

Lithium-metal battery survives 1,000 cycles, powers LED even when cut

Researchers in South Korea have unveiled a tri-layer composite solid electrolyte (CSE) that boosts ion transport and suppresses dendrite growth in lithium-metal batteries (LMBs). Lithium-metal batteries can store much more energy than conventional lithium-ion batteries. The higher energy density could give electric vehicles (EVs) a much longer driving range. But they are prone to forming dangerous lithium dendrites, which has so far limited thei…

Lithium-metal battery dendrite-free cycling clocks 1,000 hours

Researchers from Chonnam National University (CNU), South Korea have demonstrated 1,000 hours of dendrite-free cycling in lithium-metal batteries (LMBs) through the development of a new tri-layer solid electrolyte, which combines flexible polymers and ceramic particles. With potential to support grid-scale energy storage and electric vehicles (EVs), the research found ionic conductivity was nearly four times higher than plain polyethylene oxide …

Void-Suppressing Lithium Anodes Could Improve All-Solid-State Batteries

The lithium-metal battery has long been regarded as the ultimate prize in rechargeable energy storage: lithium is exceptionally light, and a metallic lithium anode can store far more charge per unit mass than the graphite used in most commercial batteries. Replacing flammable liquid electrolytes with solid materials could also improve safety and enable batteries with […]
