摘要： A high pulse power electrochemical cell comprising an alkali metal-aluminum alloy anode, a nickel anode current collector, a calendared mixed metal oxide cathode active material pressed onto a cathode current collector comprising aluminum and a nonaqueous electrolytic solution, is described. The electrolytic solution preferably comprises at least one ion-forming alkali metal salt of hexafluorophosphate with the alkali metal salt being similar to the alkali metal comprising the anode. Lithium is the preferred alkali metal. This cell system produces high current pulses and can be housed in a casing having a reduced volume with respect to conventional electrochemical systems. Additionally, the anode/electrolytic solution exhibits reduced voltage delay without comprising heat dissipation.

摘要： An electrochemical cell comprising a lithium anode, a silver vanadium oxide cathode having a relatively lower basis weight, and an electrolyte activating the anode and the cathode is described. By limiting the amount of cathode active material per unit area (i.e. basis weight) facing the anode in the Li/SVO cell, the magnitude of the passivating film growth at the solid-electrolyte interphase (SEI) and its relative impermeability to lithium ion diffusion is reduced. Therefore, by using a cathode of a relatively low basis weight active material, it is possible to eliminate or significantly reduce undesirable irreversible Rdc growth and voltage delay in the cell and to extend its useful life in an implantable medical device.

摘要： A new design for a cathode having a configuration of: SVO/first current collector/CFx/second current collector/SVO is described. The two cathode current collectors are vertically aligned one on top of the other in a middle region or zone of the cathode. This coincides to where a winding mandrel will be positioned to form a wound electrode assembly with an anode. The overlapping region of the two current collectors helps balance the expansion forces of the exemplary SVO and CFx active material layers. This, in turn, helps maintain a planar cathode that is more amenable to downstream processing. The use of two current collectors on opposite sides of an intermediate cathode active material also provides for enhanced reliability when cathodes are wound from the center as they lend structural integrity to outer portions of the wind.
摘要翻译：描述了具有以下配置的阴极的新设计：SVO /第一集电器/ CFx /第二集电器/ SVO。在阴极的中间区域或区域中，两个阴极集电体在另一个的顶部垂直对准。这一点与绕组心轴将被定位以形成具有阳极的卷绕电极组件的情况相一致。两个集电器的重叠区域有助于平衡示例性SVO和CF x活性材料层的膨胀力。这又有助于维持更适合于下游处理的平面阴极。在中间阴极活性材料的相对侧上使用两个集电器还提供了当从中心缠绕阴极时提高可靠性，因为它们将结构完整性提供给风的外部部分。

摘要： An electrochemical cell comprising an electrode, whether it is the cathode of a primary cell or an anode or a cathode of a secondary cell, comprised of a mixture of a robust, high temperature binder along with a sacrificial decomposable polymer is described. The robust binder remains in the electrode throughout formation and processing, and maintains adhesion and cohesion of the cathode during utilization. The sacrificial decomposable polymer is present during the electrode formation stage. However, it is decomposed via a controlled treatment prior to electrode utilization. Upon subsequent high pressure pressing, the void spaces formerly occupied by the sacrificial polymer provides sites where the electrode active material collapses into a tightly compressed mass with enhanced particle-to-particle contact between the active material particles. For a cathode in a primary cell, for example a Li/SVO cell, the result is believed to be improved rate capability, capacity and stability throughout discharge.
摘要翻译：描述了包括电极的电化学电池，无论其是初级电池的阴极还是二次电池的阳极或阴极，由稳定的高温粘合剂与牺牲的可分解聚合物的混合物组成。在整个形成和加工过程中，坚固的粘合剂保留在电极中，并且在使用期间保持阴极的粘附和内聚力。牺牲可分解聚合物在电极形成阶段存在。然而，它在电极利用之前通过受控处理分解。在随后的高压压制之后，先前由牺牲聚合物占据的空隙空间提供了电极活性材料塌陷成紧密压缩的物质的位置，其中活性材料颗粒之间具有增强的粒子与粒子之间的接触。对于初级电池中的阴极，例如Li / SVO电池，结果被认为是在整个放电过程中提高速率能力，容量和稳定性。

摘要： An improved cathode material for nonaqueous electrolyte lithium electrochemical cell is described. The preferred active material is silver vanadium oxide (SVO) coated with a protective layer of an inert metal oxide (MxOy) or lithiated metal oxide (LixMyOz). A preferred coating method is by a sol-gel process. The SVO core provides high capacity and rate capability while the protective coating reduces reactivity of the active particles with electrolyte to improve the long-term stability of the cathode.

摘要： The current invention relates to the preparation of an improved cathode active material for non-aqueous lithium electrochemical cell. In particular, the cathode active material comprises ε-phase silver vanadium oxide prepared by using a γ-phase silver vanadium oxide starting material. The reaction of γ-phase SVO with a silver salt produces the novel ε-phase SVO possessing a lower surface area than ε-phase SVO produced from vanadium oxide (V2O5) and a similar silver salt as starting materials. Consequently, the low surface area ε-phase SVO material provides an advantage in greater long-term stability in pulse dischargeable cells.

摘要： The present invention is directed to a method for analyzing the tail-end behavior of a lithium cell having a solid cathode. The tail of a longer-term accelerated discharge data (ADD) test is estimated from the tail of two shorter-term ADD tests. This is accomplished by first comparing the discharge tails of shorter-term ADD tests and determining angles or rotation that correspond to Rdc growth, and then trending rotation angles versus time to reach a give DoD. For example, the 18-month and 36-month ADD test tails are used to estimate the ADD test tail of a similarly constructed cell subjected to a longer-term ADD test, for example a 48-month ADD test.
