Power on the move: NiCd and NiMH small sealed rechargeable batteries

Meeting the demand for mobility has spurred growth in small rechargeable batteries. Although mobile computing and portable communications applications for batteries are most prominent, other battery-powered devices such as power tools, consumer appliances, and toys are all experiencing significant growth in volume. The improvement in performance of the NiCd cell is the baseline. There is improvement from changing to another nickel-based chemistry: the nickel-metal hydride couple, which is now penetrating much of the high-end rechargeable market. The nickel-based couples continue to offer the most robust and cost-effective batteries on the market today
