Special membrane preparation power battery has the following advantages:
High temperature resistance: ceramic coating has excellent high temperature characteristics, more than 180C can also maintain the diaphragm form.
High safety: neutral electrolyte in the free HF, enhance the battery acid resistance, improve safety
High magnification performance: Alumina in the lithium battery can be a solid solution, improve the performance and cycle performance.
Low capacity loss: alumina can inhibit the formation of oxygen and LIPF decomposition, reduce the electrochemical specific capacity loss
Good wetting: nano ceramic powder has a good absorption and liquid retention capacity.
Unique self-shut-off characteristics: to keep the polyolefin membrane closed-cell characteristics, to avoid the heat caused by loss of safety risks
Good consistency: to make up for the pole piece, electrolyte, ordinary diaphragm and other possible defects, improve the battery consistency
Low self-discharge rate: the coating increases the micro-tortuous degree, self-discharge is lower than the ordinary diaphragm
Long cycle life: reduce the cycle of mechanical short circuit, effectively improve the cycle life
