    摘要： Organic lithium salts suitable for use in electrolytes for primary or secondary rechargeable batteries include de-localized bulky anions over Lewis acid fragments, typically BF3, and organic moieties. The organic moieties may be, for example, anions derived from fused nitrogen heterocycles (e.g. benzeneimidate, benzitriazolate and the like); multi carboxylates (e.g. oxalate, 1,2,4,5-benzenetetracarboxylate and the like), and pyromellitic diimidate. The organic lithium salts of the invention have the general formula: Liq[Org(MXn)m], in which Org represents the organic moieties and MXn represents an organic or inorganic boron, aluminum or phosphorous containing Lewis acid. The organic lithium salts are conveniently prepared by reacting an organic compound having at least one de-protonation group selected from NH, OH, SH or COOH with an inorganic or organic lithium compound to generate an organic lithium processor salt, and thereafter bringing the organic lithium processor salt into contact with an inorganic or organic Lewis acid to obtain the organic lithium product salt.

    摘要： A reversible lithium ion cell has a graphitic material as the anode material, and the electrolyte includes propylene carbonate and also a chlorinated diethyl carbonate, and a lithium salt, the concentration by weight of the chlorinated diethyl carbonate being less than 2%. The chlorinated diethyl carbonate appears to form a passivating layer on the surface of the graphite that prevents interaction of propylene carbonate with graphite, but does not impede reversible intercalation of lithium ions. Such cells may be used over a wide temperature range, and have good capacity.

    摘要翻译： 可逆锂离子电池具有石墨材料作为阳极材料，电解质包括碳酸亚丙酯和氯化碳酸二乙酯，以及氯化二乙基碳酸酯的重量浓度小于2％的锂盐。 氯化二乙基碳酸酯似乎在石墨表面形成钝化层，防止碳酸亚丙酯与石墨的相互作用，但不妨碍锂离子的可逆嵌入。 这样的电池可以在宽的温度范围内使用，并具有良好的容量。

    摘要： A nonaqueous electrolyte and a lithium-ion secondary battery using the same, wherein a mixture of a cyclic carbonate, a chain carbonate, a first phosphoric acid ester wherein bonding between carbons is a single bond, and a second phosphoric acid ester wherein bonding between carbons contains a double bond is used as the nonaqueous electrolyte. It is desirable that the first phosphoric acid ester is a trimethyl phosphate. In addition, it is desirable that the second phosphoric acid ester is a dimethylisopropenyl phosphate.
