Thermal, Electrical, and Environmental Safeties of Sulfide Electrolyte-Based All-Solid-State Li-Ion Batteries.

The next generation of all-solid-state lithium-ion batteries (ASLIBs) based on solid-state sulfide electrolytes (SSEs) is closest to commercialization. Understanding the overall safety behavior of SSE-ASLIBs is necessary for their product design and commercialization. However, their safety behavior in real-life situations, such as battery exposure to high temperature, overcharge, mechanical rupture, and air exposure, remains largely unknown.

Enhancing Electrochemical Performances of Rechargeable Lithium-Ion Batteries via Cathode Interfacial Engineering.

Lithium-ion batteries (LIBs) have transformed modern electronics and rapidly advancing electric vehicles (EVs) due to their high energy and power densities, cycle-life, and acceptable safety. However, the comprehensive commercialization of EVs necessitates the invention of LIBs with much enhanced and stable electrochemical performances, including higher energy/power density, cycle-life, and operational safety, but at a lower cost. Herein, we report a simple method for improving the high-voltage (up to 4.
