Example Embodiment
[0032] Example 1, which is different from Comparative Example 1, is that this embodiment includes the following steps:
[0033] Step 1. Select silicon particles with a particle size of 100nm, a porous graphene sheet with a sheet thickness of 3nm and a sheet diameter of 50μm as the conductive agent component (the mass ratio between silicon particles and graphene is 99:1 ); The pore diameter of the porous graphene is 1 μm, and the width d1 of the continuous part between the two pores is about 5 μm;
[0034] Others are the same as those of Comparative Example 1, and will not be repeated here.
Example Embodiment
[0035] The second embodiment is different from the first embodiment in that this embodiment includes the following steps:
[0036] Step 1. Select silicon particles with a particle size of 100nm, a porous graphene sheet with a sheet thickness of 3nm and a sheet diameter of 50μm as the conductive agent component (the mass ratio between silicon particles and graphene is 99:1 ); The pore diameter of the porous graphene is 1 μm, and the width d1 of the continuous part between the two pores is about 1 μm;
[0037] Others are the same as in Example 1, and will not be repeated here.
Example Embodiment
[0038] Embodiment 3 is different from Embodiment 1 in that this embodiment includes the following steps:
[0039] Step 1. Select silicon particles with a particle size of 100nm, a porous graphene sheet with a sheet thickness of 3nm and a sheet diameter of 50μm as the conductive agent component (the mass ratio between silicon particles and graphene is 99:1 ); The pore diameter of the porous graphene is 1 μm, and the width d1 of the continuous part between the two pores is about 0.5 μm;
[0040] Others are the same as in Example 1, and will not be repeated here.
