Cell charge-discharge curves based on Co3O4 prepared with different heat treatment conditions. Prepared at 200°C for 10 h, the Co3O4 were heat treated at (a) 200°C for 3 h; (b) 300°C for 3 h; (c) 400°C for 3 h; (d) cycling behavior of Co3O4 electrodes (voltage range 0.001 to 2.5 V versus Li/Li+; 0.1 C-rate).
