Negative electrode for alkaline secondary battery, and alkaline secondary battery
Abstract:
A battery comprises an electrode group including a separator, a positive electrode and a negative electrode. The negative electrode comprises a negative electrode core, negative electrode mixture layers retained to the negative electrode core, and a fluorine resin layer disposed on the surface of the negative electrode mixture layers. The negative electrode mixture layers include a first outermost peripheral region located at the outermost periphery of the electrode group and a second outermost peripheral region located opposite to the first outermost peripheral region. When the amount of the fluorine resin constituting a first fluorine resin layer in a portion of the first outermost peripheral region is represented by A, and the amount of the fluorine resin constituting a second fluorine resin layer in a portion of the second outermost peripheral region is represented by B, a relation A>B is satisfied.
