Nickel-zinc batteries get a new lease on life


Over 110 years ago, the legendary inventor Thomas Edison was granted a patent for the nickel-zinc (NiZn) battery, but a multitude of technical problems blocked the commercial success of this type of battery, and it vanished into distant memory. However, the situation started to change around 2000, when nickel-zinc battery technology again became a focus of intensive research due certain advantages over nickel-cadmium (NiCd) and nickel metal hydride (NiMH) batteries – in particular a higher cell voltage, which simplifies the use of primary batteries as direct power sources. The EU is also campaigning to prohibit the use of NiCd batteries due to their cadmium content. The first generation of NiZn rechargeable batteries is now available in AAA and AA formats from suppliers such as Conrad and Volkner (in Germany). [via]
