A battery case (1) houses a battery with a plurality of non-prismatic electrochemical cells and at least one electronic component. The battery case includes a plurality of cell housings (12) and at least one electronic component housing (18) that accommodates the at least one electronic component. The plurality of cell housings each define an internal space (11) sized to accommodate one of the electrochemical cells, and include an internal surface (16) at least a portion of which is shaped to substantially correspond to a non-prismatic exterior surface (22) of the one of the electrochemical cells to be housed by the cell housing, and an external surface at least a portion of which follows contours of a corresponding portion of the inner surface.
摘要:
An improved cathode suitable for lithium-sulfur batteries, a battery including the cathode, and a battery including a separator containing inorganic fillers are disclosed. The cathode includes sulfur and a metal oxide and optionally includes an additional polymeric material. The metal oxide reduces dissolution of sulfur at the cathode and reduces sulfur-containing deposits on the battery anode, thereby providing a battery with relatively high energy density and good partial discharge performance. The separator also reduces unwanted diffusion of sulfur species. The battery also has a breakable barrier (514) disposed between an electrolyte and at least one of the anode and the cathode.
摘要:
At least a portion of the enclosure of a thermal battery is formed of a ceramic material that is non-porous and electrically-non-conductive. The thermal battery includes at least one cell, a squib that when activated causes the at least one cell to become active, and an enclosure that surrounds the at least one cell and the squib. Squib terminals and battery terminals extend through the enclosure and are electrically connected to the squib and to the at least one cell, respectively. At least the portion of the enclosure through which the squib and battery terminals extend is formed of the ceramic material. The enclosure includes a container and a header. At least the header is made from the ceramic material, and preferably both the container and the header are made from the ceramic material.
