Screening and Optimization of Electrolytes for High-Performance Lithium-Ion Batteries, Lithium-Ion Batteries, Electrolyte Screening, Battery Performance

The performance of lithium-ion batteries (LIBs) is strongly influenced by several factors, including ion transport, internal resistance, and overall efficiency. This study aims to identify optimal electrolytes for high-performance LIBs by screening various candidates based on their conductivity, density, and viscosity. A range of liquid electrolytes containing salts at different concentrations was evaluated. Conductivity was measured using a SevenExcellence S700 conductivity meter, density with a 200 μL pipette and a 5-digit precision balance, and viscosity with a RheoSense μVISC Portable viscometer. Electrolyte solutions exhibiting high conductivity, moderate density, and low viscosity were selected for further testing in coin cell batteries. By establishing conductivity, density, and viscosity as key screening parameters, this study provides valuable insights for designing optimized electrolyte formulations to improve battery efficiency and lifespan.
