摘要
将催化剂纳米NiO掺入多孔炭基氧气电极中,组装成CR2032型锂-氧扣式实验电池,并进行恒流充放电和交流阻抗测试。催化剂纳米NiO可改善电池的电化学性能。在0.1 mA/cm2的电流密度下,电池的首次放电比容量为1 258.4mAh/g,放电电压平台稳定在2.7 V左右,充电电压平台为4.2 V。
Catalyst nano-NiO was doped into porous carbon based oxygen electrode to assemble CR2032 type Li-oxygen button experimental cell,then galvanostatic charge-discharge and AC impedance tests were taken. Catalyst nano-NiO could improve the electrochemical performance of the cell. The initial specific discharge capacity of the cell was 1 258.4 mAh/g at the current density of 0.1 mA/cm2, the discharge voltage platform stabilized around 2.7 V and charge voltage platform was 4.2 V.
