| titleOfInvention | Copper sulfide anode and preparation method thereof |
| abstract | The invention provides a copper sulfide anode and a preparation method thereof, solving the problems of the conventional copper sulfide electrode that the bonding force of active substances and current collectors is poor and the anode conductivity is lowered because of a binder and also solving the problems of the integrated copper sulfide electrode which is synthesized in situ in a solution that the quantity of active substances is small and the preparation period is long. The copper sulfide anode is prepared by the following steps: uniformly spreading elemental sulfur which is prepared according to the sulfur carrying amount of foamy copper is 0.03-0.3g/cm<2> on the foamy copper, putting into a furnace, and carrying out in-situ reaction under a protection gas at a temperature of 155-350 DEG C so as to obtain the laminated copper sulphide which takes a foamy copper three-dimensional network structure as a framework, namely an integrated porous copper sulphide anode. By utilizing the copper sulfide anode, the application of the three-dimensional structured integrated porous anode in a lithium battery is widened, the energy density of a lithium battery anode is improved, and the performances of a lithium battery are improved. The copper sulfide anode is simple in preparation process, low in equipment requirement, low in cost and convenient for industrial production. |
