REDUCING HAZARD OF LITHIUM DENDRITES IN LITHIUM CELLS

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.
