摘要： A sealed cell having a safety mechanism is provided. The safety mechanism has a non-resealable valve structure formed in a sealing plate that seals the cell. The valve structure is broken as soon as the internal pressure reaches or exceeds a predetermined value so as to permit the internal gas to be released outside. The valve structure has at least one dome protruding toward the interior of the cell, which in turn has at the periphery thereof a break groove for facilitating the breakage of the valve structure. This makes the valve structure highly responsive to the internal pressure and causes to form a break-opened orifice of a sufficient area at the time of operation in response to the increased internal pressure. The valve structure is not unnecessarily broken by the impacts of, for example, dropping. As a result, the safety of the sealed cell is significantly improved.

摘要： Voltage delay in an active metal anode/liquid cathode battery cell can be significantly reduced or completely alleviated by coating the active metal anode (e.g., Li) surface with a thin layer of an inorganic compound with Li-ion conductivity using chemical treatment of Li surface. Particularly, preferred examples of such compounds include lithium phosphate, lithium metaphosphate, and/or their mixtures or solid solutions with lithium sulphate. These compounds can be formed on the Li surface by treatment with diluted solutions of the following individual acids: H3PO4, HPO3 and H2SO4, their acidic salts, or their binary or ternary mixtures in a dry organic solvent compatible with Li, for instance in 1,2-DME; by various deposition techniques. Such chemical protection of the Li or other active metal electrode significantly reduces the voltage delay due to protected anode's improved stability toward the electrolyte.

摘要： A primary lithium electrochemical cell housed in a casing having a curved side wall intermediate opposed generally planar face walls is described. The cell comprises an anode and a cathode that each has a plurality of face portions joined together by connecting portions. The opposite polarity face portions and connecting portions are aligned with each other and then the electrodes are wound to provide an electrode assembly that fits in the casing. Regardless whether the cell is balanced as either an anode-limited or cathode-limited configuration, however, it is desirable to have the active material of one electrode face portion directly facing the electrode material of the counter electrode face portion. This means that the dimensional extent of the facing electrodes should be as close to each other in areas as possible to match the desired anode- or cathode-limited balance. The same is true for the connecting portions. The cell is of a high energy density for an implantable biomedical device.
摘要翻译：描述了容纳在壳体中的初级锂电化学电池，其具有中间相对的大致平坦的面壁的弯曲侧壁。电池包括阳极和阴极，每个阳极和阴极具有通过连接部分连接在一起的多个面部。相反的极性面部分和连接部分彼此对准，然后缠绕电极以提供装配在壳体中的电极组件。然而，无论电池是否被平衡为阳极限制或阴极限制的结构，希望使一个电极面部分的活性材料直接面对对电极面部的电极材料。这意味着面对电极的尺寸范围应尽可能地相互接近以匹配所需的阳极或阴极限制的平衡。对于连接部分也是如此。该细胞对于植入式生物医学装置具有高能量密度。

摘要： Rechargeable electrochemical cell, with a negative electrode, which in charged state contains an active metal selected from the group of the alkaline metals, the alkaline-earth metals and the metals of the second subgroup of the periodic table of elements; an electrolyte solution based on sulfur dioxide; and a positive electrode containing the active metal, from where ions come out into the electrolyte solution during the charging process. A self discharge reaction takes place at the negative electrode, for which the sulfur dioxide of the an electrolyte solution reacts with the active metal of the negative electrode to form a poorly soluble compound. According to the invention, the electrochemical charge quantity of the sulfur dioxide in the cell, calculated with one faraday per mole sulfur dioxide, is smaller than the charge amount of the active metal which can be theoretically electrochemically accumulated in the positive electrode.
