▎ 摘  要

NOVELTY - Battery cell (100) comprises a first electrode (140A), a second electrode (140B), a solid state electrolyte layer (110) interposed between the first electrode and the second electrode, and a resistive layer interposed between the first electrode and the second electrode. The resistive layer is electrically conductive to regulate an internal current flow within the battery cell. The internal current flow resulting from an internal short circuit is formed between the first electrode and the second electrode. The internal short circuit is formed from the solid state electrolyte layer penetrated by metal dendrites formed at the first electrode or the second electrode. USE - Battery cell. ADVANTAGE - The short circuit current can generate a large quantity of heat (e.g., thermal runaway) within the battery cell that can lead to combustion of the battery cell. The first polymer electrolyte layer and the base film layer can be configured to prevent a decomposition of the solid state electrolyte layer during a production and/or an operation of the battery cell. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the battery cell consistent with implementations of the current subject matter. 100Battery cell 110Solid state electrolyte layer 120Polymer electrolyte layer 130Base film layer 140A, 140BElectrodes
