Fig. (a) are the galvanostatic charge-discharge curves of BNAs integrated electrode at a current density of 25 μA cm-2 . The 1st, 2nd discharge capacities of BNAs integrated electrode are 2471.5, 2311.7 μAh·cm-2 (1861.8, 1741.4 mAh g-1). Fig. (b) reveals the rate capability of BNAs integrated electrode at current densities of 250, 500, 1000, 2000, 5000 μAh·cm-2 respectively. The discharge capacities are 1219, 1128, 972, 678, 430 μAh·cm-2 (918.2, 849.7, 732.2, 510.7, 323.9 mAh g-1), respectively. Fig. (c) shows the cycling stability of BNAs integrated electrodes. Reversible capacity of BNAs integrated electrodes can maintain a capacity of 410 μAh·cm-2 (308.8 mAh g-1, at a current density of 320 μAh·cm-2) after 600 cycles. When the current density was 75 μAh·cm-2, the electrode exhibits a high capacity of 600 μAh·cm-2 (451.9 mAh g-1) after 500 cycles. The above results show that the integration of active material and current collector can greatly improve the capacity, rate ability and cyclical stability of the battery.
