    Abstract: The present invention provides a novel composition and method for preventing decomposition of one or more electrochemical cell components comprising an electrode having an active material, and an electrolyte. The method of the invention, for the first time, effectively overcomes problems which arise between the interaction of cell components and contaminate water retained in a cell. Such contaminate water reacts with the electrolyte which comprises a salt of lithium in a solvent. Solubilizing of the salt in solution with attendant interaction between the salt and water causes formation of hydrogen-containing acids. The method of the invention effectively blocks decomposition of a lithium metal oxide cathode active material, and particularly lithium manganese oxide (LMO, nominally LiMn.sub.2 O.sub.4). Such decomposition is prevented by including in the cell a basic compound which forms an electron donor species in the electrolyte solution; and by neutralizing at least a portion of the acid by reacting the donor species with the hydrogen-containing acids thereby preventing decomposition of the lithium manganese oxide by the acid. The preservation of the lithium manganese oxide prevents degradation of other cell components by other mechanism.

    Abstract translation: 本发明提供一种用于防止一种或多种电化学电池元件分解的新型组合物和方法，所述电化学电池组件包括具有活性材料的电极和电解质。 本发明的方法第一次有效地克服了细胞成分的相互作用和污染细胞中残留的水之间产生的问题。 这种污染水与包含锂在溶剂中的盐的电解质反应。 溶解盐中的盐与盐和水之间伴随的相互作用引起含氢酸的形成。 本发明的方法有效地阻止锂金属氧化物正极活性物质，特别是锰酸锂（LMO，名义上是LiMn 2 O 4）的分解。 通过在电解液中包含在电解质溶液中形成电子供体物质的碱性化合物来防止这种分解; 并且通过使供体物质与含氢酸反应从而中和酸的至少一部分，从而防止酸分解锰酸锂。 锂锰氧化物的保存通过其他机理防止其他电池组分的降解。

    Abstract: Non-aqueous electrochemical cells with improved performance can be fabricated by employing anodes comprising a composition having graphite particles that have a BET method specific surface area of about 6 to about 12 m.sup.2 /g and a crystallite height L.sub.c of about 100 nm to about 120 nm, and wherein at least 90% (wt) of the graphite particles are less than 16 .mu.m in size; a cathode; and a non-aqueous electrolyte containing a solvent and salt that is interposed between the anode and cathode. When employed in an electrochemical cell, the anode can attain a specific electrode capacity of at least 300 mAhr/g. The electrochemical cell has a cycle life of greater than 1500 cycles, and has a first cycle capacity loss of only about 10% to about 15%.

    Abstract: The present invention provides for the preparation of an “optimized” VPO4 phase or V—P—O/C precursor. The VPO4 precursor is an amorphous or nanocrystalline powder. The V—P—O/C precursor is amorphous in nature and contains finely divided and dispersed carbon. Throughout the specification it is understood that the VPO4 precursor and the V—P—O/C precursor materials can be used interchangeably to produce the final vanadium phosphates, with the V—P—O/C precursor material being the preferred precursor. The precursors can subsequently be used to make vanadium based electroactive materials and use of such precursor materials offers significant advantages over other processes known for preparing vanadium phosphate compounds.
