Abstract: An insulator ring for preventing short circuit contact between the opposite polarity electrode in a case-terminal cell design is described. Typically, a lithium/silver vanadium oxide cell is built in a case-negative design with the casing serving at the negative terminal. The cathode is connected to an insulated terminal pin. In a conventional cell construction, the electrode assembly is enclosed in an insulator bag in addition to the electrode separator envelopes before being housed inside the casing. The insulator bag ensures the cathode electrode will not come into short circuit contact with the casing. In the present invention, the insulator bag is replaced with an insulator ring which only protects those portions of the electrode assembly vulnerable to short circuit contact.
Abstract translation: 描述了一种用于防止壳体端子电池设计中的相反极性电极之间的短路接触的绝缘环。 通常，锂/银氧化钒电池内置在壳体负极设计中，壳体在负极端子处。 阴极连接到绝缘端子引脚。 在常规电池结构中，除了电极分离器的包封之外，电极组件被封装在绝缘体袋中，然后被容纳在壳体内。 绝缘子袋确保阴极不会与壳体发生短路接触。 在本发明中，绝缘体袋被绝缘体环代替，绝缘环仅保护电极组件的那些部分易于短路接触。

Abstract: An insulator structure forming a physical barrier encapsulating the entire electrode assembly including all the positive portions and segregating them from the negative leads and the casing is described. By completely encapsulating the electrode assembly including the cathode lead portions from the anode leads and the casing, no opposite polarity structures that can potentially serve as a surface for lithium bridging are left exposed to electrolyte.

Abstract: an electrochemical cell comprising a cathode of a powder material pressed into intimate contact with a rod-shaped current collector and an anode at least partially wrapped around the cathode is described. The cathode current collector is preferably provided with a plurality of offset flats offset with respect to each other. This helps prevent the cathode active material from sliding off of the rod-shaped current collector. The anode has spaced apart edges at opposite ends of its width that form a gap with the anode wrapped around the cathode. This helps in sliding the anode/cathode electrode assembly into a cylindrical tube comprising the cell casing. A preferred chemistry is a lithium/CFx activated with a nonaqueous electrolyte.

Abstract: An electrochemical cell comprising a cathode material contacted to a perforated current collector having a portion left uncovered and an anode material contacted to an anode current collector is described. A separator sheet segregating the anode from direct contact with the cathode is folded back upon itself along a crease with an upper portion at least partially sealed to a lower portion along an aligned peripheral edge to form an envelope. A first envelope portion houses the cathode having the uncovered portion of the cathode current collector spaced from the crease and a second envelope portion houses the anode. The first envelope portion is sealed to the second envelope portion through the uncovered perforations of the cathode current collector to lock the anode aligned with the cathode. The anode and cathode are then wound into a jellyroll electrode assembly housed in a cylindrical casing and activated with an electrolyte.

Abstract: The present invention relates to a current collector for an electrochemical cell. The current collector is a substrate having a grid pattern comprising open areas converging at an imaginary focal point on a connector tab of the substrate. The openings are grouped into distinct regions with the larger openings immediately adjacent to the connector tab and the smaller openings distant there from. This provides more conductive pathways at greater distances from the tab.

Abstract: An electrochemical cell is described. The cell comprises a cathode material contacted to a perforated current collector having a portion left uncovered and an anode material contacted to an anode current collector. The anode comprises first and second strips positioned on opposite sides of the cathode, which is also in the form of a strip, but one that is much longer than each of the anode strips. Proximal ends of the anode strips reside adjacent to where the cathode is secured to a terminal pin/sleeve assembly. Distal ends of the anode strips are adjacent to the opposed ends of the cathode strip. A separator sheet segregating the anode from direct contact with the cathode provides an upper portion at least partially sealed to a lower portion along an aligned peripheral edge and through the uncovered perforations of the cathode current collector to lock the cathode in position. The anode and cathode are then wound into a galaxy electrode assembly housed in a cylindrical casing and activated with an electrolyte.
