Their adoption in power tools and early digital cameras revealed the potential for portable devices, changing expectations of how we work and live. Nickel (Ni) has long been widely used in batteries, most commonly in nickel cadmium (NiCd) and in the longer-lasting nickel metal hydride (NiMH) rechargeable batteries, which came to the fore in the 1980s.
