High-Voltage-Resistant Highly Stable Solid Polymer Electrolyte via In Situ Integrated Construction with Fast Ion Migration.

Electric aircraft such as electric aircraft and electric vehicles play a key role in the future electric aviation industry, but they put forward huge requirements for battery energy density. However, the current high-energy-density lithium battery technology still needs to be broken through. Herein, through the molecular structure design of the polymer electrolyte, a strategy of a fast migration channel and wide electrochemical window is proposed to fabricate high-voltage-resistant solid polymer electrolyte (HVPE) via in situ polymerization.

Optimization Design of Fluoro-Cyanogen Copolymer Electrolyte to Achieve 4.7 V High-Voltage Solid Lithium Metal Battery.

Raising the charging voltage and employing high-capacity cathodes like lithium cobalt oxide (LCO) are efficient strategies to expand battery capacity. High voltage, however, will reveal major issues such as the electrolyte's low interface stability and weak electrochemical stability. Designing high-performance solid electrolytes from the standpoint of substance genetic engineering design is consequently vital.
