Abstract: An electrochemical device comprises collector plates having main parts and tab parts and being arranged such that the main parts oppose each other; a separator having a main part and a tab part and being arranged such that the main part is disposed between the main parts of the collector plates while the tab part projects out from between the main parts of the collector plates; an active material layer formed on each of the main parts of the collector plates and in contact with the separator; an electrolyte in contact with each active material layer; and an insulative fixing member securing the tab parts of the collector plates and the tab part of the separator to each other.
Abstract: An air-cooled battery enclosure includes a battery tray frame having a floor section including a plurality of outer slats joined to a lower floor frame. A plurality of corner posts extend upward from the lower floor frame. An array of a plurality of criss-crossed inner slats are joined to the outer slats. Outer side walls join the posts, the outer slats and a set of inner slats in a criss-crossed array of cubbyhole compartments. Each cubby hole compartment contains a battery. A plurality of air spaces are located between respective adjacent walls of the enclosure frame for circulation of cooling gas, such as air. In an alternate embodiment stackable battery trays have outer walls with corrugations to space batteries within the tray from outer walls and an open mesh floor. Criss-crossed internal spring baffles with shallow bends within the trays form spaces for the circulation of cooling gas.
