Waste Cu scraps and waste copper etchant were simultaneously recycled in the form of tetrahedron-like CuCl crystal via one-step facile comproportionation reaction, and its electrochemical Li-storage performance was also evaluated. The results show that the resultant tetrahedron-like CuCl crystals possess four smooth triangular surfaces and six isometric sides. CuCl-based anode delivers a reversible discharge capacity of 101.8 mAh/g even cycling at 10 C for 2 000 cycles, which is greater than that of graphite anode under the same conditions, implying the satisfactory long term Li-storage cyclic stability at a high rate. These results could facilitate to promote the development of circular economy mode of waste Cu-based resources and sustainable energy.
