锂电池电极浆料评价方法

Evaluation method of lithium battery electrode slurry

电极浆料会影响涂布速度、涂布均匀性等,最终影响电池的一致性,因此浆料需要好的流动性、稳定性和均匀性。介绍了判断锂电池正负极浆料性质的主要表征参数:粘度、流变特性、固含量和粒度等,并介绍了几种表征手段。

Electrode slurry affects the coating speed,coating uniformity,and ultimately affect the consistency of the battery,so the slurry needs good fluidity,stability and uniformity.Several characterization parameters were mainly introduced to judge the properties of slurry,such as viscosity,rheological properties,solid content and particle size,as well as several characterization methods.
