Abstract
Abstract A modular battery construction comprising one or more cells, each cell having positive and negative electrodes formed by parallel, thin sheets of porous, inert material impregnated with finely divided electrode materials, and a thin sheet of porous inert material impregnated with electrolyte is sandwiched between the electrodes. A stack of cells is mounted in each casing, which casings are nestable together in any desired number. Each casing has an end wall and a peripheral side wall adapted to nestingly engage the side wall of an adjacent casing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
197 words
A modular battery comprising: a. a plurality of stacks of thin flat cells, each cell having a positive and a negative electrode plate and a thin sheet member containing an electrolyte disposed between such electrode plates; b. a plurality of nestable means for defining an outermost casing for said battery and for separately containing said cell stacks, each said nestable means comprising an end wall of wall area larger than the area of any one of said cell plates and sheet members and sidewalls supported on each edge of said end wall and extending beyond both sides thereof, the sidewalls of adjacent of said nestable means being engageable and thereupon defining with the end walls of said adjacent nestable means separate adjacent containers for said cell stacks, said end walls each defining an aperture Therethrough, the end wall apertures of adjacent of said nestable means being axially aligned upon such engagement of said sidewalls; and c. pressure sensitive probe means for monitoring the gas pressures in said separate cell stack containers comprising hollow tube means extending through said end wall apertures for defining pressure-sensing openings extending from said hollow tube means into each of said separate containers.
Claim 2
Dependent Claim
197 words
A modular battery comprising: a. a plurality of stacks of thin flat cells, each cell having a positive and a negative electrode plate and a thin sheet member containing an electrolyte disposed between such electrode plates; b. a plurality of nestable means for defining an outermost casing for said battery and for separately containing said cell stacks, each said nestable means comprising an end wall of wall area larger than the area of any one of said cell plates and sheet members and sidewalls supported on each edge of said end wall and extending beyond both sides thereof, the sidewalls of adjacent of said nestable means being engageable and thereupon defining with the end walls of said adjacent nestable means separate adjacent containers for said cell stacks, said end walls each defining an aperture Therethrough, the end wall apertures of adjacent of said nestable means being axially aligned upon such engagement of said sidewalls; and c. pressure sensitive probe means for monitoring the gas pressures in said separate cell stack containers comprising hollow tube means extending through said end wall apertures for defining pressure-sensing openings extending from said hollow tube means into each of said separate containers.
Claim 3
Dependent Claim
44 words

Claim 4
Dependent Claim
58 words
The modular battery claimed in claim 1 wherein each said end wall includes first and second electrically conductive pin members extending therethrough, said battery further including first and second connector means for connecting said first and second pin members respectively to the positive and negative electrode plates of the cell stack adjacent one side of said end wall.
Claim 5
Dependent Claim
30 words
