Abstract: A porous carbon material includes carbon nanotubes and carbon material particles, a particle elastic modulus of the porous carbon material is Y1, and 0.9 Gpa≤Y1≤5.0 Gpa. The porous carbon material of this application has a high particle elastic modulus and a high powder conductivity. When a silicon-carbon material prepared using the porous carbon material in this application as a skeleton is used in an electrochemical apparatus, the silicon-carbon material can have a high particle elastic modulus and powder conductivity, improving the electrochemical performance of the electrochemical apparatus such as the long cycling performance and rate performance.
