Abstract: Techniques are described for monitoring the degradation of electrochemical cells. A battery monitoring system monitors, for each of one or more cells of a plurality of cells in a battery, an amount of mechanical deformation using one or more measuring devices. The battery monitoring system determines a number of cells of the plurality of one or more monitored cells for which the monitored amount of mechanical deformation exceeds a deformation threshold. The battery monitoring system determines whether the determined number of cells exceeds a threshold number of cells with an amount of mechanical deformation exceeding the deformation threshold. Responsive to determining the determined number of cells exceeds the threshold number of cells, the battery monitoring system sends a notification that the battery is degraded beyond an acceptable limit.

Abstract: A lithium battery cell is disclosed. The lithium battery cell includes particles such as silicon oxide (e.g., glass) that can reduce thermal runaway within the battery cell due to the presence of lithium metal dendrites within the battery cell. As lithium metal dendrites heat up due to shorting a cathode and anode in the battery cell, the particles may encapsulate the lithium metal dendrites to absorb the heat and reduce the ongoing reaction within the cell.
