| titleOfInvention | A kind of method for surface nanometerization of copper current collector |
| abstract | The invention relates to the field of lithium ion batteries, in particular to a method for surface nanometerization of a copper current collector. The method includes: 1) eroding copper matrix to prepare and pre-matrix; 2) reducing pre-matrix to prepare porous template; 3) depositing active metal to prepare activated template; 4) using anode dissolution principle to prepare precursor; 5) calcining to prepare surface-deposited Active metals and carbon and form nanostructured copper current collectors. The method of the invention is simple, has strong repeatability and good controllability; the three-dimensional nano-copper is electrochemically inert and has a stable structure; the structure of the three-dimensional nano-copper will greatly reduce the diffusion channels of lithium ions and reduce polarization, and can greatly reduce the The cycle performance and rate performance are improved; by depositing active metal elements and further increasing the specific surface area of the nanostructure, the electrochemical performance of the electrode material is further improved; the negative electrode material prepared by the method of the present invention does not need to use a binder and conduct electricity. agent, which increases the specific capacity of the battery. |
