Interface-enhanced metalized current collector for structural battery and method of making the same

By constructing a gradient chemical bonding interface through mild wet chemical modification and metallization processes, the problem of balancing conductivity and mechanical properties of current collectors in structural batteries was solved. This resulted in a current collector with high conductivity, high interfacial bonding force, and high structural strength, thereby improving the mechano-electrochemical stability and cycle life of the battery.

Abstract

The application belongs to the technical field of batteries, and discloses an interface enhanced metalized current collector for structural batteries and a preparation method thereof. The preparation method of the interface enhanced metalized current collector comprises the following steps: first, a prepreg is selected, then the prepreg is immersed into a surface metalization plating solution containing a metal salt to perform a reaction, and a continuous metal conductive layer is formed on the surface and the internal pores of the prepreg to obtain the interface enhanced metalized current collector. The preparation method of the metalized current collector avoids high-temperature carbonization and introduces a chemical bonding interface, solves the problems of mechanical property brittleness and weak interface bonding force caused by carbonization in the prior art, and thus a structural current collector with high bearing capacity and high electrochemical stability is obtained.
