Abstract: In order to maintain electrical contact between the anode, cathode and electrolyte layers in an electrochemical cell, a layer of material under tension is wrapped around the cell so that the material compresses the layers together to ensure sufficient electrical contact. Alternatively, a metal, foam or inflatable gas spring is employed in a housing structure containing the electrochemical cell to apply a compressive force to achieve the same result.

Abstract: There is provided an electrochemical cell which has a non-metal negative electrode (anode on discharge). The anode is not a solid metal, is not metallic, and has no free metal. Rather, an amount of lithium ions are incorporated into the anode carbon-polymer structure. The anode of the invention has no more than a minor amount of lithium in a precharged or fully discharged state. The anode is used with lithium-containing cathodes (positive electrodes), preferably of the intercalation type. The anode of the invention is of a material which includes carbon, an electrolyte, and one or more constituents selected from the group consisting of metal and semi-metal elements and compounds and alloys thereof, other than lithium and its alloys. Such constituents are further characterized by an ability to react electrochemically with lithium by accepting and releasing lithium. Preferred metals and semi-metals include aluminum, boron and silicon, and compounds and alloys thereof, such as AlSi.

Abstract: This invention is directed to solid electrolytes containing a solvent and, in particular, a solvent comprising a mixture of an organic carbonate and glyme as well as electrolytic cells prepared from such solid electrolytes.

Abstract: An apparatus for shielding adjacent batteries during testing includes a shell with partitions to form an array of pockets, and a cover with shields. When a cover is placed in a closed position on top of the shell, each shield would contact a corresponding partition to completely isolate two batteries placed in two pockets adjacent to the shield and partition. In this manner, even if a battery catches fire or leaks, the partition and the shield minimizes the effect on an adjacent battery.
