| Abstract: | The properties of sub C size (Cs) Ni/MH batteries are described. The average capacity of the batteries is 2.4Ah. The discharge capacity at 5C rate offers 89% of the capacity at 0.2C rate. This Cs battery has a good performance at low temperature. The SEM and XPS surface analysis show the hydrogen storage alloy electrode of the battery oxidized and pulverized after charge-discharge cycles. The electrochemical impedance behaviour of Cs battery at different depth of discharge has also been investigated. |
