摘要： A method for reducing residual water content in a battery material includes placing the battery material having residual water adsorbed therein in a channel substantially sealed from an ambient environment. A gaseous mixture is caused to flow through the battery material in the channel. The gaseous mixture includes an organic solvent vapor present in an amount effective to hydrogen bond with at least some water molecules from the battery material. The gaseous mixture is caused to flow through the battery material for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure. The organic solvent vapor having at least some water molecules bonded thereto is removed from the battery material. The removing takes place for a predetermined amount of time, at a predetermined temperature, and at a predetermined pressure, thereby forming the battery material having reduced residual water content.

摘要： Lithium titanate, Li 4 Ti 5 O 12 , particles containing surface hydroxyl groups are susceptible to unwanted gas generation (such as hydrogen) in the presence of water contamination when the particles are used as active anode electrode material in lithium-ion cells operating with an anhydrous liquid electrolyte. In accordance with this disclosure, the hydroxyl groups on the surfaces of the particles are reacted with one of a group of selected agents containing organic alkoxy groups to form hydrophobic moieties on the surfaces of the particles which effectively block water molecules from the surfaces of lithium titanate particles in the anode of the cell.

摘要： Some lithium-ion batteries are assembled using a plurality of electrically interconnected battery pouches to obtain the electrical potential and power requirements of the battery application. Such battery pouches may be prepared to contain a stacked grouping, or a wound grouping, of inter-layered and interconnected anodes, cathodes, and separators, each wetted with a liquid electrolyte. A reference electrode, an optional auxiliary reference electrode, and adjacent enclosing modified working electrodes are combined in a specific arrangement and inserted within the stack structure, or the wound structure, of other cell members to enable accurate assessment of both anode group and cathode group performance, and to validate and regenerate reference electrode capability.
