Abstract: A battery module is disclosed. The battery module comprises a housing, a heat-conducting fin disposed within the housing having a first fin surface and a second fin surface, the first fin surface and the second fin surface defining a respective first housing cavity and a second housing cavity within the housing. The battery module further comprises a first battery cell disposed within the first housing cavity and engaging the first fin surface and a second battery cell disposed with the second housing cavity and engaging the second fin surface. The heat-conducting fin is adapted to conduct heat from the first and second battery cells outwardly from the housing.

Abstract: An optimized lithium ion battery cell is disclosed. The battery cell comprises an anode and a cathode. The cathode is coated with a cathode coating comprising a cathode mixture of a cathode powder adapted for an energy cell application, a binder, and a conductive agent. The cathode mixture is of a respective ratio of 3 (binder) to 2 (conductive agent) to 95 (cathode powder). The anode is coated with an anode coating comprising an anode mixture of an anode powder adapted for an energy cell application, a first binder, a second binder, and a conductive agent. The anode mixture is of a respective ratio of 1.5 (first binder) to 2 (conductive agent) to 94 (anode powder) to 2.5 (second binder).

Abstract: A high rate lithium battery can include a cathode composition coated on a substrate. The cathode composition can include first and second active materials and binder. The first and second active materials can have different characteristics including, for example, particle size, tap density, and amount of conductive component. The first and second active materials can be combined to achieve higher packing densities of the active material, which may allow for a higher capacity battery as compared to conventional batteries formed with a single active material.

Abstract: Cathode and anode structures for a battery each include one or more tabs welded to a substrate. A method of making a battery may include providing tabs welded to a substrate of each of a cathode and anode of the battery. Tabs for a cathode or anode structure may be provide from the same or similar material as the substrate of a corresponding cathode or anode.
