METHOD AND APPARATUS FOR MONITORING SELF-DISCHARGE PHENOMENA OF ELECTROCHEMICAL CELLS

원문 (중국어)

A method for monitoring self-discharge phenomena of electrochemical cells, comprising the steps of: a) providing a plurality of electrochemical cells, wherein each cell has a first dimension and a second dimension, extending respectively along a first direction and a second direction orthogonal to one another, greater than a third dimension extending along a third direction orthogonal to the first direction and the second direction, wherein each cell comprises a casing and a plurality of layers arranged inside the casing, wherein the layers comprise at least one first electrode layer, at least one second electrode layer and at least one first separator layer interposed between the first electrode layer and the second electrode layer; b) arranging the cells inside a container, wherein the pressure inside the container is equal to a first pressure; c) bringing the pressure inside the container to a second pressure greater than the first pressure; d) measuring a voltage of each cell of the plurality of cells to detect whether a self-discharge value of said cell is greater than a predetermined threshold, wherein step c) is prior to or at least partially simultaneous with step d), and step d) is prior to a step of assembling the cells into one or more batteries.
