Metal insertion Negative coupling

The nickel-metal hydride couple lends itself to a wound eonstruetion similar to that used by present-day wound niekel-eadmium cells. The basie components consist of the positive and negative eleetrodes insulated by plastic separators similar to those used in nickel-cadmium products. The sandwiched electrodes are wound together and inserted into a metallic can which is sealed after injection of a small amount of potassium hydroxide electrolyte solution. Tne result is a cell which bears a striking resemblance to current sealed nickel-cadmium cells. The nickel-metal hydride chemistry is also applicable to prismatic cell designs which evoke greater interest as product profiles become thinner.
