Abstract
An electrical power storage unit has one or more metal-gas electrical cells, each cell including a pair of generally planar outer electrode units configured to define therebetween an interior space for containing an electrical power storage medium and an inner electrode unit mounted between the pair of outer electrode units so as to be in electrically conductive contact with the electrical power storage medium and define a plurality of volumes each having a pair of open ends, each open end facing an adjacent outer electrode unit. The power storage medium is a slurry containing active metal particles and an electrolyte solution. The inner electrode unit is configured for removable insertion within the interior space. The volumes defined by the inner electrode unit are configured so as to contain portions of the power storage slurry such that removal of the inner electrode unit from the interior space causes the simultaneous removal therefrom of the major part of the power storage slurry. Each outer electrode unit includes a generally planar gas electrode, a device for separating the metal particles from the gas electrode, and a device for preventing mechanical damage to the device for separating upon removal of the inner electrode unit from the interior space and upon insertion of the inner electrode unit into that space.
