| titleOfInvention | Preparation method of composite phase change coating beneficial to heat dissipation of lithium ion battery |
| abstract | The invention provides a preparation method of a composite phase change coating beneficial to heat dissipation of a lithium ion battery, which comprises the steps of melting phase change agent paraffin under the condition of 80 ℃ water bath, adding attapulgite, encapsulating the phase change agent in the attapulgite with a pore structure to form a phase change precursor, mixing the phase change precursor with alumina sol, carrying out ball milling dispersion to obtain uniform slurry, and coating to form the composite phase change coating. The invention adopts paraffin as the phase change agent, the latent heat of phase change is large, the attapulgite is the phase change agent adsorption carrier, the internal surface area is large, the adsorption performance is good, the coating thickness is reduced, the adsorption quantity of the paraffin phase change agent is increased, the alumina sol is the film forming matrix, the good heat conduction performance can overcome the defect of low heat conduction coefficient of the paraffin, the heat conduction and heat dissipation performance of the coating is effectively improved, the composite phase change coating is coated on the battery shell, the internal temperature of the battery can be reduced by 2-5 ℃, and the purpose of efficient heat dissipation is achieved. |
