The nickel-hydrogen battery exhibits an energy density of ∼140 Wh kg−1in aqueous electro- lyte and excellent rechargeability without capacity decay over 1,500 cycles. The estimated cost of the nickel-hydrogen bat- tery reaches as low as ∼$83 per kilowatt-hour, demonstrating attractive potential for practical large-scale energy storage.

When the capacity decreases to about 80%, the battery can not be used in EV, but can be used for electric energy storage. The retired batteries are obviously different from new batteries on the aspect of the decline characteristics, the cost composition, operation performance and economic benefits. When the retired batteries are applied to the power

While a constant capacity was obtained for the half-cell, a rapid capacity decay was seen for the capacity balanced full-cell. SEI formation can consequently not explain the decrease in the capacity
