Powdered polymer binders for high viscosity processing for anode fabrication

Disclosed is a composition comprising a non-spherical powdered cross-linked polymer obtained by grinding wherein the cross-linked polymer comprises monomeric units 1, 3 butadiene, (hydroxyethyl) methacrylate and trimethylolpropane trimethacrylate, and the non-spherical powdered cross-linked polymer has a particle size D (90) of 180-450 [mu] m. The composition further comprises a silica anti-blocking agent. These compositions are useful as binders in anodes of rechargeable batteries. 公开了一种组合物，其包含通过研磨获得的非球形粉末状交联聚合物，其中该交联聚合物包含单体单元1,3丁二烯、甲基丙烯酸(羟乙基)酯和三羟甲基丙烷三甲基丙烯酸酯，并且该非球形粉末状交联聚合物具有180-450μm的粒度D(90)。该组合物进一步包含二氧化硅防结块剂。这些组合物用作可充电电池的阳极中的粘合剂。
