Abstract
An environment-friendly battery conductive coating material is prepared from, by weight, 40-60 parts of a base material, 15-25 parts of a conductive additive, 10-18 parts of inorganic filler and 8-15 parts of a modified additive. According to the reasonable raw material ratio and a large number of experimental proofs, the environment-friendly battery conductive coating material has good adhesive force and low contact resistance, the consumption of an adhesive can be effectively lowered, and environmental protection performance of battery manufacturing is improved; the conductive coating contains no methylbenzene or xylene with high noxiousness and meanwhile is better in sealing effect.
Description
Technical field
The present invention relates to battery rapidoprint technical field, be specifically related to the battery conductive coating material of a kind of environment-friendly type.
Background technology
Development along with ferric phosphate lithium cell; become the probability of automobile power cell because it has and constantly paid close attention to by each side; characteristic due to himself; rate LiFePO 4 material develops to nanorize, and this is allowed to poor processability, in order to improve its processing characteristics; reduce pole piece resistance or the internal resistance of cell; conductive coating technology starts to obtain the application of scale, and thus to more professional development, and extend to some other relevant industries.
Conductive coating is also referred to as precoated shet, is often referred to be coated on one layer of conductive coating of plus plate current-collecting body aluminium foil surface in lithium battery industry, and the aluminium foil of coating conductive coating is referred to as precoated shet aluminium foil or is called for short coated aluminum foil.Conductive coating can be effectively improved pole piece adhesive force in lithium battery, reduces the usage amount of binding agent, and the electrical property simultaneously for battery is also obviously improved.Turned out a prestigious institution along with the development of new forms of energy industry, particularly ferric phosphate lithium cell in recent years, became new technique very powerful and exceedingly arrogant in the industry or new material.The existing conductive coating materials feature of environmental protection is poor.
