摘要： The invention related to a liquid electrolyte for a lithium battery comprising a lithium salt dissolved in a mixture of three non-aqueous organic solvents. This mixture consists of:33% to 49 volume % of propylene carbonate,33% to 49 volume % of diethyl carbonate, and2% to 34 volume % of ethyl acetate.The liquid electrolyte is in particular suitable for a lithium battery based on the LiFePO4/Li4Ti5O-12 pair or derivatives thereof, these materials being the respective active materials of the positive and negative electrodes. Such a lithium battery in fact has the advantage of operating in power, over a wide temperature range, while at the same time preserving a low self-discharge capacity.

摘要： A method of producing Liy[NixCo1−2xMnx]O2 wherein 0.025≦x≦0.5 and 0.9≦y≦1.3. The method includes mixing [NixCo1−2xMnx]OH2 with LiOH or Li2CO3 and one or both of alkali metal fluorides and boron compounds, preferably one or both of LiF and B2O3. The mixture is heated sufficiently to obtain a composition of Liy[NixCo1−2xMnx]O2 sufficiently dense for use in a lithium-ion battery cathode. Compositions so densified exhibit a minimum reversible volumetric energy characterized by the formula [1833−333x] measured in Wh/L.
