摘要： The invention provides a new route for the synthesis of carbon-coated powders having the olivine or NASICON structure, which form promising classes of active products for the manufacture of rechargeable lithium batteries. Carbon-coating of the powder particles is necessary to achieve good performances because of the rather poor electronic conductivity of said structures. For the preparation of coated LiFePO 4 , sources of Li, Fe and phosphate are dissolved in an aqueous solution together with a polycarboxylic acid and a polyhydric alcohol. Upon water evaporation, polyesterification occurs while a mixed precipitate is formed containing Li, Fe and phosphate. The resin-encapsulated mixture is then heat treated at 700 °C in a reducing atmosphere. This results in the production of a fine powder consisting of an olivine LiFePO 4 phase, coated with conductive carbon. When this powder is used as active material in a lithium insertion-type electrode, fast charge and discharge rates are obtained at room temperature and an excellent capacity retention is observed.
摘要翻译：本发明提供了一种用于合成具有橄榄石或NASICON结构的碳涂覆粉末的新途径，其形成用于制造可再充电锂电池的有希望的活性产品类别。由于所述结构的电子导电性差，所以粉末颗粒的碳涂层是必需的，以获得良好的性能。为了制备涂覆的LiFePO 4，将Li，Fe和磷酸盐源与多元羧酸和多元醇一起溶解在水溶液中。当水蒸发时，在形成含有Li，Fe和磷酸盐的混合沉淀物的同时发生聚酯化。然后将树脂包封的混合物在还原气氛中在700℃下进行热处理。这导致由导电碳涂覆的由橄榄石LiFePO 4相组成的细粉末的生产。当这种粉末用作锂插入型电极中的活性材料时，在室温下能够获得快速的充放电率，并且观察到优异的容量保持率。

The obtained powders have a particle size of less than 1 μm, and provide superior electrochemical performances once mixed for an appropriate time with electrical conductive powder.

摘要： The present invention relates to lithium secondary batteries and more specifically to positive electrode materials operating at potentials greater than 2.8 V vs. Li + /Li in nonaqueous electrochemical cells. In particular, the invention relates to crystalline nanometric carbon- free olivine-type LiFePO 4 powders with enhanced electrochemical properties. A direct precipitation process is described for preparing crystalline LiFePO 4 powder, comprising the steps of: - providing a water-based mixture having at a pH between 6 and 10, containing a water -miscible boiling point elevation additive, and Li (I) , Fe (II) and P (V) as precursor components; - heating said water-based mixture to a temperature less than or equal to its boiling point at atmospheric pressure, thereby precipitating crystalline LiFePO4 powder. An extremely fine 50 to 200 nm particle size is obtained, with a narrow distribution. The fine particle size accounts for excellent high-drain properties without applying any carbon coating. This allows for a significant increase in the active material content of the electrode. The narrow distribution facilitates the electrode manufacturing process and ensures a homogeneous current distribution within the battery.

摘要： The invention relates to active materials for the manufacture of Li-based batteries. A crystalline nanometric powdered material with formula Li x (M, M')PO 4 , in particular Li x FePO 4 (O≤x≤1), is disclosed, exhibiting single phase Li insertion/extraction mechanism at room temperature when used as positive electrode material in Li-based batteries. Compared to current LiFePO 4 , the novel material results in smooth, sloping charge/discharge voltage curves, greatly simplifying the monitoring of the state of charge of the batteries. The coexistence of mixed valence states for Fe (i.e. Fe III VFe II ) is believed to increase the electronic conductivity in the room temperature single phase Li x FePO 4 material, compared to state of the art two-phase materials. This, together with the nanometric size of the particles and their sharp monomodal size distribution, contributes to the exceptional high-rate capability demonstrated in batteries.
