CoO作为电极材料的可能性

The possibility of CoO as electrode material

以烧结Ni(OH)2为对电极,以Inco Ni粉为导电剂,对CoO作为电极材料使用时的电化学性能进行了测试和分析。结果表明:CoO在室温时的放电容量远高于镉-镍电池中的CdO和氢-镍电池中的商业化AB5贮氢合金,且受温度影响不大,充放电循环稳定性较好。不足之处是其放电电压平台较低,在充放电循环时,放电容量有波动。

Employing sintered Ni（OH）2 as counter electrode and IncoNi powder as conductive agents,the electrochemical properties of CoO as electrode material were investigated. The results indicate that the discharge capacity of CoO at room temperature is much higher than CdO in CdO/Ni battery and ABs hydrogen storage alloy in MH/Ni battery, and it has good temperature stability. The drawback of CoO used as electrode material is that the discharge platform is very low and the discharge capacities undulate at charge-discharge cycling.
