Semi-Solid-State Coated Separator 半固态涂覆隔膜

·Adopting a composite design of "peelable adhesive layer + functional layer", the coating transfer rate can reach 95%. The hot pressing process is compatible with existing production lines, which can significantly improve production yield and consistency. ·The solid electrolyte functional layer enhances heat resistance, and the composite structure effectively reduces interfacial impedance, prolongs battery thermal chamber endurance time, and improves safety performance. ·By introducing high-wettability materials, electrolyte wettability is optimized while maintaining coating structure stability, improving battery cycle performance. ·Coating PVDF/PMMA on the surface of the functional layer increases adhesion to electrodes and mitigates lithium dendrite formation. The adhesion between the coating and electrodes is therefore superior to that between the coating and the base film, preventing direct contact between cathode and anode during battery thermal runaway and improving cell thermal safety. ·Suitable for prismatic wound and cylindrical cells, serving for power batteries. ·采用 “可剥离胶层 + 功能层” 的复合设计，涂层转印率可达 95%，热压工艺与现有产线兼容，可显著提升生产良率与一致性 ·其固态电解质功能层可增强耐热性，复合结构有效降低界面阻抗，延长电池热箱耐受时间，提升安全性能 ·引入高浸润材料，在维持涂层结构稳定的前提下优化电解液浸润性，改善电池循环性能 ·将PVDF/PMMA涂覆于功能层表面，可以增加与极片之间的粘结性，改善锂枝晶，使得涂层与极片之间的粘接力优于涂层与基膜之间的粘接力，在电池热失控时起到防止正负极直接接触，改善电芯的热安全 ·产品应用于方形、圆柱等电池类型，服务于动力电池领域
