NEGATIVE ELECTRODE PLATE, LITHIUM SECONDARY BATTERY, AND APPARATUS CONTAINING SUCH LITHIUM SECONDARY BATTERY
DRIVE
June 23, 2022
This application provides a lithium secondary battery and a negative electrode plate for the lithium secondary battery. The negative electrode plate includes a negative electrode current collector and a negative electrode active material layer disposed on at least one surface of the negative electrode current collector, where a surface of the negative electrode active material layer closer to the current collector is provided with an elastic coating. And the elastic coating includes an elastic polymer and a conductive agent. At a pressure of 1 MPa to 20 MPa, the elastic coating has a compression deformation of 20% to 80% and an elastic modulus of 1 MPa to 800 MPa. And optionally, at the pressure of 1 MPa to 20 MPa, the elastic coating has a compression deformation of 30% to 60% and an elastic modulus of 5 MPa to 100 MPa.
