Abstract: Lithium ion batteries and cells, as well as operating and testing methods are provided, which utilize a transparent pouch to monitor the battery in operational condition and/or in operation. Covers may be used to prevent illumination of battery components when testing is not required, and the covers may be removed or have modifiable transparency configured to enable visual monitoring. Indicators in the transparent pouch may be associated with cell components such as electrodes and electrolyte to indicate their condition. For example, the transparent pouch may be used to monitor battery safety, e.g., by enabling to monitor lithium metallization on an anode (directly or via indicators), monitor battery lifetime and other operational parameters, without having to damage the battery.

Abstract: Methods, stacks and electrochemical cells are provided, in which the cell separator is surface-treated prior to attachment to the electrode(s) to form binding sites on the cell separator and enhance binding thereof to the electrode(s), e.g., electrostatically. The cell separator(s) may be attached to the electrode(s) by cold press lamination, wherein the created binding sites are configured to stabilize the cold press lamination electrostatically—forming flexible and durable electrode stacks. Electrode slurry may be deposited on a sacrificial film and then attached to current collector films, avoiding unwanted interactions between materials and in particular solvents involved in the respective slurries. Dried electrode slurry layers may be pressed or calendared against each other to yield thinner, smother and more controllably porous electrodes, as well as higher throughput. The produced stacks may be used in electrochemical cells and in any other type of energy storage device.
