BNAs Improve Performance of Li-ion Batteries

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.

Clean Power is Not Enough

Due to residual fossil fuel emissions that would remain even with very stringent climate policies enacted from 2020 on, so-called negative emission technologies to remove carbon dioxide from the atmosphere will be necessary to comply with the 1.5°C limit.

Coal power versus wind and solar energy - debates about the Paris climate targets often centre around electricity supply. Yet, even in a world of stringent climate policies and a clean power generation, the remaining use of fossil fuels in industry, transport and heating in buildings could still cause enough
