Abstract
Abstract Battery comprising a container housing a plurality of sealed cells employing an oxyhalide-, halide- and/or liquid sulfur dioxide-containing nonaqueous electrolyte, and a porous shock absorbing material impregnated with an immobilizing agent which will react with and neutralize any oxyhalide, halide, liquid sulfur dioxide or their reaction products that escape from the cells.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
177 words
A battery comprising an outer container having an opening at the top and a closed base member; disposed within said container at least two nonaqueous cells employing an electrolyte solution containing at least a liquid selected from the group consisting of an oxyhalide, a halide, liquid sulfur dioxide and mixtures thereof, said cells electrically connected in predetermined electrical relation so as to provide two electrode terminals for a cell assembly disposed at the open end of the container; a terminal board having two external terminals exposed on its surface and being secured to the open end of the container, each of said external terminals being electronically connected to one of the two electrode terminals of the cell assembly; and a resilient material disposed within the container between the cells and at least a portion of an inner wall of the container, said resilient material containing an immobilizing chemical agent that will substantially react with and neutralize any of the oxyhalide, halide, liquid sulfur dioxide, mixtures thereof or their reaction products that escape from any of the cells.
Claim 2
Dependent Claim
177 words
A battery comprising an outer container having an opening at the top and a closed base member; disposed within said container at least two nonaqueous cells employing an electrolyte solution containing at least a liquid selected from the group consisting of an oxyhalide, a halide, liquid sulfur dioxide and mixtures thereof, said cells electrically connected in predetermined electrical relation so as to provide two electrode terminals for a cell assembly disposed at the open end of the container; a terminal board having two external terminals exposed on its surface and being secured to the open end of the container, each of said external terminals being electronically connected to one of the two electrode terminals of the cell assembly; and a resilient material disposed within the container between the cells and at least a portion of an inner wall of the container, said resilient material containing an immobilizing chemical agent that will substantially react with and neutralize any of the oxyhalide, halide, liquid sulfur dioxide, mixtures thereof or their reaction products that escape from any of the cells.
