Abstract
A multi-cell battery in which a plurality of electrochemical cells are disposed in a battery case. The battery case includes one or more partitions which divide the interior of the case into a plurality of cell compartments that house the electrochemical cells. The battery case includes at least one gas channel have a tortuous pathway designed to trap electrolyte which may escape from the cell compartments. A unique battery terminal may be molded into the battery case.
Claims26
A multi-cell battery comprising:
- a battery case including one or more partitions dividing the interior of said case into a plurality of compartments;
- and
- a plurality of electrochemical cells, each of said electrochemical cells disposed within a cell compartment of said case;
- and
- wherein said battery case further includes a gas channel positioned in a direction above the cell compartment and a gas vent, said gas channel having a tortuous flow path in fluid communication with said gas vent, said gas channel defined at least by a wall and a plurality of lower spaced ribs extending from the wall and a plurality of upper spaced ribs extending from the wall, said upper spaced ribs positioned substantially above the lower spaced ribs in said direction above the cell compartment, the wall having a plurality of holes therethrough, each of said holes being in fluid communication with a cell compartment and said gas channel.
