KETEP 세계에너지시장정보

Effective energy storage is paramount to society's transition to renewable energy. Lithium metal batteries (LMBs) have the potential to double the amount of energy stored in a single charge compared to current lithium ion batteries (LIBs), but lithium dendrite growth and electrolyte consumption in current LMB technologies are hindering battery performance.
"Considering the poor cycling performance (charge-discharge cycles) of SPEs stemming from low mechanical and thermal properties, this project focused on the fabrication of SPEs reinforced by a bilayer substrate comprised of a layer of PET nonwoven fabric and a layer of PVDF nanofibers to improve the structural stability and thus the cycle performance of SPEs," said Ick Soo Kim, corresponding author of the study and professor at the Nano Fusion Technology Research Group in the Institute for Fiber Engineering (IFES) at Shinshu University.
