In the pursuit of enhancing all-solid-state lithium-ion batteries (ASSLIBs), researchers are pushing the boundaries of battery technology by identifying innovative anode materials. The current industry challenge is finding solutions to prevent dendrite growth, a common issue with lithium-metal anodes, affecting battery performance and safety.

Solid-state batteries (SSBs) utilize solid electrolytes, eliminating the dangers associated with liquid electrolytes and potential fires. However, these batteries demand sophisticated technology to ensure stable performance during charging cycles. The anode material choice is pivotal, influencing the battery's efficiency and longevity.

Traditionally, lithium-metal has been the focus as an anode for SSBs, but it suffers from dendrite-induced short circuits. Silicon alternatives also face setbacks, including conductivity issues and expansion-induced cracks.

A promising discovery has been made by researchers from the Korea Electrotechnology Research Institute (KERI), Kumoh National Institute of Technology, and Inha University. They have developed a tin (Sn)-based alloy, particularly ‘FeSn2,’ that has shown resilience during battery operation. This material adapts by reducing particle size over repeated cycles, enhancing the connectivity of solid particles and forming a stable, uniform electrode.

FeSn2’s superior elasticity and ability to withstand deformation ensure its stability under demanding conditions without cracking. Testing in a full cell with FeSn2 anodes resulted in an areal capacity much higher than existing lithium-ion batteries, with impressive stability over 1,000 cycles.

These advancements pave the way for high-energy density batteries, signifying potential for commercialization of non-flammable SSBs. The results have been prominently featured in a prestigious energy journal, marking a significant step forward in battery technology innovation.
