    摘要： An electrochemical cell battery is disclosed having current collecting terminals acting as security device. The battery includes a plurality of electrochemical cells connected in series or parallel; each electrochemical cell having a current collecting terminal connecting the positive current collectors together and a current collecting terminal connecting the negative current collectors together; the current collecting terminals each having a folded extension arm for electrically connecting two adjacent electrochemical cells together. The current collecting terminals utilize layers of PTC materials strategically positioned whereby if a temperature of an electrochemical cell rises above the transition temperature of the layer of PTC material, electrical current is prevented to flow between electrochemical cells by the layer of PTC material.

    摘要翻译： 公开了一种电化学电池，其具有用作安全装置的集电端子。 电池包括串联或并联连接的多个电化学电池单元; 每个电化学电池具有将正极集流体连接在一起的集流端子和将负极集流体连接在一起的集流端子; 每个集电端子具有折叠的延伸臂，用于将两个相邻的电化学电池单元电连接在一起。 集电端子利用策略性地定位的PTC材料层，从而如果电化学电池的温度升高到高于PTC材料层的转变温度，则防止电流通过PTC材料层在电化学电池之间流动。

    摘要： A back-up power system having a monitoring system for determining, and for allowing remote monitoring of, a back-up time can be provided by a plurality of batteries for a given application, at all times. The back-up power system includes a plurality of batteries (10(1) to (10(n)), each having an integrated circuit adapted to monitor individual battery's state of health. The back-up power system also includes a data management unit (25) for evaluating the back-up time available from the plurality of batteries based on a sum of individual battery available capacity, a measured ambient temperature (35) and a continuously updated measured application current load (34). The available back-up time and the measured application current load are accessible to a remote user (30) via a communication link (28).

    摘要： The method relates to a pyrometallurgical and hydrometallurgical process for the recovery and recycling of lithium and vanadium compounds from a material comprising spent rechargeable lithium batteries, particularly lithium metal gel and solid polymer electrolyte rechargeable batteries. The method involves providing a mass of the material, hardening it by cooling at a temperature below room temperature, comminuting the mass of cooled and hardened material, digesting with an acid its ashes obtained by incineration, or its solidified salts obtained by molten salt oxidation, or the comminuted mass itself, to give a mother liquor, extracting vanadium compounds from the mother liquor, separating heavy metals and aluminium therefrom, and precipitating lithium carbonate from the remaining solution.

    摘要： An apparatus for monitoring a thickness of a film in motion. The apparatus comprises a roller for receiving and supporting the film in motion, the roller being adapted to rotate about an axis of rotation. The apparatus also comprises a position detector for detecting when the roller is in a specific angular position as the roiler rotates about the axis of rotation. The apparatus further comprises a measurement unit aligned with a specific portion of the roller and coupled to the position detector. The measurement unit is responsive to a detection of the roller being in the specific angular position to measure the thickness of the film.

    摘要： A process for making an electrode sheet for lithium electrochemical cells is disclosed. The process comprises the steps of : a) admixing a polyether polymer or copolymer soluble in water, at least one lithium salt, at least one electrochemically active material and water to form a water-based solution/suspension containing by weight at least 20% active electrode material, at least 5 % of a polyether polymer or copolymer, and at least 1.5 % lithium salt; b) coating the water-based solution/suspension in the form of an electrode thin film onto an electrode support; and, c) drying the electrode thin film to obtain an electrode thin sheet having less than 1000ppm of residual water. The electrode thin sheet thereby formed has less than 10% porosity after drying. The drying step is preferably carried out through a dryer/oven tunnel having incremental drying zones.
