Positive electrode material for lithium-ion battery

The present invention relates to a precursor of a negative electrode compartment for rechargeable metal-air batteries, comprising a rigid casing (), at least one solid electrolyte membrane (), a protective covering (), completely covering the inside face of the solid electrolyte membrane (), a metallic current collector () applied against the inside face of the protective covering (), preferably also a block () of elastic material applied against the current collector and essentially filling the entire internal space defined by the walls of the rigid casing and the solid electrolyte (), and a flexible electronic conductor () passing in a sealed manner through one of the walls of the rigid casing. The present invention also relates to a negative electrode compartment having a rigid casing obtained from said precursor and to a battery containing such a negative electrode compartment.

Positive electrode material for a lithium-ion accumulator

An alloy comprising tin, silicon and carbon, and containing a crystalline M-Sn phase, M being an inert metal. An alloy comprising tin and silicon, comprising: A manufacturing process for this alloy.

Active material composition for the negative electrode of a lithium-ion accumulator

An electrode comprises a porous three-dimensional conductive support and at least one reinforcing metal band fixed along a longitudinal edge portion of the support and having a coefficient of elongation to rupture equal to at least 20% in a direction parallel to the edge portion of the support. Two longitudinal edge portions of the band are bent against the same face of the band, at least part of whose surface is pressed against the support.

Spiral-wound electrode with three-dimensional support

A process of preparing an electrode for an electrochemical cell comprising a foamlike porous metal support (1) loaded with active material, wherein, on each side of said support there is placed a separator layer (2, 3) made of polyolefin fibers, and wherein the assembly thus obtained is compressed so as to produce an adhesive bond between the layers of separator and the entire surface of said support.
