Disclosed herein is a safety feature for batteries comprising an integrated series of lithium-ion bi-cells. Each individual bi-cell comprises, sequentially, an anode, a film separator, a cathode, a film separator, and an anode. When multiple bi-cells are joined within a single package an insulator element, preferably an electrolyte permeable insulator element, is placed between anode elements of adjoining bi-cells. This insulator element appears to restrict internal shorting during crushing of the battery, thus avoiding undesirable effects of shorting such as thermal run-away and producing a safer battery.
