    摘要: An active electrode material for electrochemical devices such as lithium ion batteries includes a lithium transition metal oxide which is free of sodium and sulfur contaminants. The lithium transition metal oxide is prepared by calcining a mixture of a lithium precursor and a transition metal oxalate. Electrochemical devices use such active electrodes.

    摘要: Primary and secondary Li-ion and lithium-metal based electrochemical cell system. The suppression of gas generation is achieved through the addition of an additive or additives to the electrolyte system of respective cell, or to the cell itself whether it be a liquid, a solid- or plastized polymer electrolyte system. The gas suppression additives are primarily based on unsaturated hydrocarbons.
