Researchers from the Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea have unveiled an innovative lithium metal battery featuring a three-layer solid polymer electrolyte. This groundbreaking design addresses long-standing safety concerns associated with dendrite formation during charging and discharging cycles.
The battery is reported to not only extinguish flames but also maintain robust performance even after numerous charge cycles. Dendrites, which resemble tree-like structures, can compromise internal connections within batteries, significantly increasing the risk of fires and explosions.
By implementing a three-layer electrolyte structure, the DGIST team aims to enhance both safety and efficiency. The outer layer is designed to be soft, ensuring optimal contact with the electrodes, thereby maximizing the battery's potential.
This development could have far-reaching implications for battery technology, particularly in electric vehicles and portable electronics, where safety and performance are paramount.
