Abstract:
A high energy density rechargeable metal-ion battery includes an anode energy layer, a cathode energy layer, a separator for separating the anode and the cathode energy layers, an anode current collector for transferring electrons to and from the anode energy layer, the battery characterized by a maximum safe voltage for avoiding overcharge, and an interrupt layer that interrupts current within the battery upon exposure to voltage in excess of the maximum safe voltage. The interrupt layer is between the anode energy layer and current collector. When unactivated, it is laminated to the cathode current collector, conducting current therethrough. When activated, the interrupt layer delaminates from the anode current collector, interrupting current therethrough. The interrupt layer includes a voltage sensitive decomposable component that upon exposure to voltage in excess of the maximum safe voltage decomposes, evolving a gas, delaminating the interrupt layer from the anode current collector, interrupting current therethrough.
