Valorization of ethylene carbonate recovered from spent lithium-ion battery electrolytes: synthesis and properties of biodegradable poly ethylene succinate- co -ethylene glycol (PESG) copolyesters
Abstract
decreased to -18.8 °C, crystallinity declined, and segmental mobility improved. Notably, PESG demonstrated optimal hydrophilicity and biodegradability, with a 75% mass loss within 24 days under lipase treatment and a contact angle reduction to 53.6°. This study validates the feasibility of recycling electrolyte waste to synthesize degradable copolyesters, offering a novel pathway for the high-value utilization of electrolyte resources and the development of environmentally friendly materials.
