In carbon nano-fiber class conductive agent, if therefore in conductive agent in right amount addition CNT, production cost can be controlled, and can carries
Conductive characteristic between high active substance and between active material and collector, so as to improve the power characteristic of lithium battery and
Cycle life, but it is to disperse to get well that CNT, which is applied to the premise in lithium ion battery, because CNT is easily rolled into a ball
Poly- phenomenon, is not easy dispersed in a solvent, disperses bad, effect might as well other conductive agents.
Rational anode formula and its preparation technology are the most important condition that can lithium battery performance play, at present according to positive pole
The species and processing technology of solvent in slurry are formulated, positive pole can divide oil system (NMP is as solvent) and water system, and (deionized water is as molten
Agent), water system technique is and cheap due to not being related to solvent recovery and problem of environmental pollution, be homogenized by environmental constraints compared with
The advantages that few and favored by big how many lithium cell factories, but conductive agent, positive active material in aqueous positive-pole slurry etc. is solid
Body material is not easy dispersed so that the uniformity of aqueous positive-pole slurry is poor, and stability is not high, easily settles, so as to lead
Send a telegraph that pond reversible capacity is smaller, and cycle performance is bad, battery capacity and cycle life are leveraged, particularly with the addition of carbon nanometer
Agglomeration easily occurs for Guan Hou, CNT, it is difficult to disperse in deionized water.
Therefore, this area needs exploitation one kind that each composition can be made uniformly to mix, so as to obtain the length with premium properties
Life-span lithium battery anode slurry.
