February 26, 2020: StoreDot assigned patent for optical communication through transparent pouches of lithium-ion batteries


This patent covers lithium-ion batteries and cells, as well as operating and testing methods, 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.


Transparent pouches based on this patent may be used to monitor and enhance battery safety and/or to modify operational parameters non-destructively, during operation of the battery.
