20130065137 | HIGH RATE AND ENERGY CATHODE MATERIAL FOR LITHIUM BATTERIES - A cathode material suitable for use in non-aqueous electrochemical cells that includes copper manganese vanadium oxide and, optionally, fluorinated carbon. A non-aqueous electrochemical cell comprising such a cathode material, and a non-aqueous electrochemical cell that additionally includes a lithium anode. | 03-14-2013 |
20130323558 | CONTOURED BATTERY CASE BASED ON CELL SHAPES - A battery case 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 and at least one electronic component housing that accommodates the at least one electronic component. The plurality of cell housings each (1) define an internal space sized to accommodate one of the electrochemical cells, and (2) include (a) an internal surface at least a portion of which is shaped to substantially correspond to a non-prismatic exterior surface of the one of the electrochemical cells to be housed by the cell housing, and (b) an external surface at least a portion of which follows contours of a corresponding portion of the inner surface. | 12-05-2013 |
20140079989 | LITHIUM-SULFUR BATTERY WITH PERFORMANCE ENHANCED ADDITIVES - A battery includes an anode containing a lithium material, a cathode containing sulfur and a porous conducting medium, and an electrolyte, wherein the electrolyte contains an additive selected from the group consisting of an organic surfactant additive, an inorganic additive, and a mixture thereof. The organic surfactant additive may be a fluorosurfactant | 03-20-2014 |
20150084603 | LITHIUM-SULFUR BATTERY AND METHODS OF REDUCING INSOLUBLE SOLID LITHIUM-POLYSULFIDE DEPOSITIONS - An improved electrolyte including a strontium additive suitable for lithium-sulfur batteries, a battery including the electrolyte, and a battery including a separator containing a strontium additive are disclosed. The presence of the strontium additive reduces sulfur-containing deposits on the battery anode, thereby providing a battery with relatively high energy density and good partial discharge performance. | 03-26-2015 |
20150084604 | LITHIUM-SULFUR BATTERY AND METHODS OF PREVENTING INSOLUBLE SOLID LITHIUM-POLYSULFIDE DEPOSITION - An improved lithium-sulfur battery containing a surface-functionalized carbonaceous material. The presence of the surface-functionalized carbonaceous material generates weak chemical bonds between the functional groups of the surface-functionalized carbonaceous material and the functional groups of the polysulfides, which prevents the polysulfide migration to the battery anode, thereby providing a battery with relatively high energy density and good partial discharge efficiency. | 03-26-2015 |
