摘要
Abstract
To address the issues of insufficient slurry stability and fluctuating electrochemical perfor-mance caused by poor compatibility between CMC and SBR in aqueous graphite anode slurries,this study compared the effects of different CMC/SBR combinations on slurry dispersibility,electrode structure,and electrochemical performance through controlled experiments and process scale-up.The results show that the combination of Daicel 2200CMC and ZEON 451B(2200@451B-2)per-formed best,with a first-cycle specific capacity of 352.6 mAh/g in half-cell tests and capacity reten-tion remaining stable at over 80％after 500 cycles.In pouch full-cell tests,its performance was com-parable to that of the PVDF system,while exhibiting the fastest lithium-ion migration rate,lowest im-pedance,and densest SEI film.The system maintained excellent performance even after process scal-ing,demonstrating optimal compatibility and industrial scalability.关键词
