US4525438A — Recombination multicell electric storage battery

Claim 1

Independent Claim 213 words

An electric storage battery comprising a plurality of cells, including two electrical end cells, electrically connected in series, each cell comprising a stack of alternating positive and negative battery plates interleaved with separator material, said separator material being capable of absorbing electrolyte in an amount sufficient to provide an electrical connection between adjacent plates of opposite polarity in the stacks, the battery containing substantially no mobile electrolyte, and each plate, with the exception of every alternate plate in the two electrical end cells, being electrically connected to a substantially coplanar plate of opposite polarity in an adjacent cell by an integral bridge piece, the bridge pieces together constituting intercell connectors, and every alternate plate in the two electrical end cells being connected to a battery terminal, each cell having at least one surface which is adjacent and opposed to a respective surface of a further cell, each pair of cells which is directly connected by an intercell connector being spaced apart and maintained in spaced relationship by only the said intercell connector and each pair of opposed surfaces of a pair of adjacent cells which is not directly connected by an intercell connector being associated with restraining means which prevent relative movement of those cells resulting in contact of the said opposed surfaces.

Claim 2

Dependent Claim 213 words

An electric storage battery comprising a plurality of cells, including two electrical end cells, electrically connected in series, each cell comprising a stack of alternating positive and negative battery plates interleaved with separator material, said separator material being capable of absorbing electrolyte in an amount sufficient to provide an electrical connection between adjacent plates of opposite polarity in the stacks, the battery containing substantially no mobile electrolyte, and each plate, with the exception of every alternate plate in the two electrical end cells, being electrically connected to a substantially coplanar plate of opposite polarity in an adjacent cell by an integral bridge piece, the bridge pieces together constituting intercell connectors, and every alternate plate in the two electrical end cells being connected to a battery terminal, each cell having at least one surface which is adjacent and opposed to a respective surface of a further cell, each pair of cells which is directly connected by an intercell connector being spaced apart and maintained in spaced relationship by only the said intercell connector and each pair of opposed surfaces of a pair of adjacent cells which is not directly connected by an intercell connector being associated with restraining means which prevent relative movement of those cells resulting in contact of the said opposed surfaces.

Claim 3

Dependent Claim 36 words

The battery of claim 1 in which the restraining means comprises an intercell partition extending between the opposed surfaces afforded by each pair of cells which are adjacent but not directly connected by an intercell connector.

Claim 4

Dependent Claim 21 words

The battery of claim 2 in which the cells are located in a container having one or more integral intercell partitions.

Claim 5

Dependent Claim 29 words

The battery of claim 1 in which the cells are located in a container closed by a lid, all the plates lying in planes substantially parallel to the lid.

Claim 6

Dependent Claim 14 words

The battery of claim 1 in which the cells are arranged in two lines.

Claim 7

Dependent Claim 48 words

The battery of claim 5 in which the cells are located in a container having one or more intercell partitions, all the intercell connectors extending between the lines and every pair of adjacent cells in the same line being separated by an intercell partition integral with the container.

Claim 8

Dependent Claim 58 words

The battery of claim 6 in which the container is of a substantially rectangular section having two sidewalls and two end walls, with one or more intercell partitions integral with each sidewall, the intercell partitions extending substantially only to the center of the container and being offset from the intercell partitions on the other side of the container.

Claim 9

Dependent Claim 147 words

An electric storage battery comprising a plurality of cells, each cell comprising a stack of alternating positive and negative battery plates interleaved with separator material, said separator material being capable of absorbing electrolyte in an amount sufficient to provide an electrical connection between adjacent plates of opposite polarity in the stacks, the battery containing substantially no mobile electrolyte and having at least two cells which afford opposed adjacent surfaces and which are directly connected by a plurality of bridge pieces constituting an intercell connector, each bridge piece being integrally formed with and interconnecting a single plate in one of the two cells to a respective plate of opposite polarity in the other cell with each so connected pair of plates being substantially coplanar, the said cells being spaced apart only by the said bridge pieces and the said opposed surfaces being separated only by an air gap.

Claim 10

Dependent Claim 147 words

An electric storage battery comprising a plurality of cells, each cell comprising a stack of alternating positive and negative battery plates interleaved with separator material, said separator material being capable of absorbing electrolyte in an amount sufficient to provide an electrical connection between adjacent plates of opposite polarity in the stacks, the battery containing substantially no mobile electrolyte and having at least two cells which afford opposed adjacent surfaces and which are directly connected by a plurality of bridge pieces constituting an intercell connector, each bridge piece being integrally formed with and interconnecting a single plate in one of the two cells to a respective plate of opposite polarity in the other cell with each so connected pair of plates being substantially coplanar, the said cells being spaced apart only by the said bridge pieces and the said opposed surfaces being separated only by an air gap.
