This application discloses an additive for lithium-ion batteries and its application. The additive has the following raw material composition by weight: 40-70 parts first solvent; 1-10 parts first polymer; 5-15 parts second polymer; 10-20 parts small molecule organic amine; and 10-20 parts stabilizer. The first polymer contains at least one nitrogen-free polar functional group; the second polymer contains at least one nitrogen-containing polar functional group; and the stabilizer is a hydrazine compound. The additive provided in this application, when used in lithium-ion batteries, can solve the problems of thick electrodes easily cracking and the difficulty in dispersing positive electrode particles.

The utility model is suitable for sliding agent processing technical field provides a kind of solid lubricant smashing device of smashing fully, including mounting bracket, pre-smashing component and smashing component being installed on mounting bracket and scraping component and material blocking component being installed on smashing component, the smashing component includes the smashing cylinder being inclinedly arranged along horizontal plane, the third smashing shaft being rotatably arranged in smashing cylinder and the smashing cutter being arranged around third smashing shaft, the scraping component includes multiple installation rods being equidistantly arranged along the axial direction of third smashing shaft, every installation rod is connected with scraping plate, and the scraping plate is attached to the inner wall of smashing cylinder.This device solves the problem that solid lubricant accumulates at the bottom of the smashing barrel, the cutter has difficulty in fully contacting the solid lubricant, leading to insufficient crushing and uneven particle size. It achieves the effect of using a multi-stage crushing method, pre-smashing the solid lubricant first, then further crushing and sieving, to ensure uniform particle size of the finished product.
