| Abstract: | As the additive of positive electrode,the nano-sized Y2O3 can improve high-temperature charge efficiency of the Ni-MH battery. The tests were performed by adding 0.5%wt,1.0%wt and 1.5%wt nano-sized Y2O3 to Ni-MH battery anode respectively. The test results showed that 0.5%wt nano-sized Y2O3 added to Ni-MH battery anode,could greatly improve the charge efficiency of Ni-MH batteries at high temperatures,but could not affect the discharge capacity,output power and internal resistance of batteries clearly. |
