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: 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. Transparent parts of the pouch may be used for direct sensing of cell elements. Removable covers may be used to protect battery components from illumination damage. Indicators in the transparent pouch may be associated with cell components such as electrodes and electrolyte to indicate their condition. External sensors may be used to derive data from the indicators, and bi-directional electromagnetic (e.g., optical) communication may be established through the transparent pouch, to enhance monitoring and spare physical electrical connections. For example, the transparent pouch may be used to monitor and enhance battery safety and/or to modify operational parameters non-destructively, during operation of 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.

Abstract: A method of preparing an anode for a Li-ion Battery comprises mixing metal particles containing at least one of Ge, Sn and Si particles with carbon particles to form a mixture, and deoxidizing the metal particles by heating the mixture in a vacuum atmosphere in a range of 10−3 to 10−6 mbar for 60-100 hours at a temperature in a range of 150 to 350° C. to form a deoxidized mixture, the deoxidation improves the Li ion absorption performance of the anode.
