摘要： An improved high energy density rechargeable (HEDR) battery with an anode energy layer, a cathode energy layer, a separator between the anode and cathode energy layers for preventing internal discharge thereof, and at least one current collector for transferring electrons to and from either the anode or cathode energy layer, includes a resistive layer interposed between the separator and one of the current collectors for limiting the rate of internal discharge through the failed separator in the event of separator failure. The resistive layer has a fixed resistivity at temperatures between a preferred temperature range and an upper temperature safety limit for operating the battery. The resistive layer serves to avoid temperatures in excess of the upper temperature safety limit in the event of separator failure in the battery, and a fixed resistivity of the resistive layer is greater than the internal resistivity of either energy layer.

摘要： A high energy density rechargeable (HEDR) metal-ion battery includes an anode and a cathode energy layer, a separator for separating the anode and cathode energy layers, and at least one current collector for transferring electrons to and from either the anode or cathode energy layer. The HEDR battery has an upper temperature safety limit for avoiding thermal runaway. The HEDR battery further includes an interrupt layer that activates upon exposure to temperature at or above the upper temperature safety limit. When the interrupt layer is unactivated, it is laminated between the separator and one of the current collectors. When activated, the interrupt layer delaminates, interrupting current through the battery. The interrupt layer includes a temperature sensitive decomposable component that, upon exposure to temperature at or above the upper temperature safety limit, evolves a gas upon decomposition. The evolved gas delaminates the interrupt layer, interrupting current through the battery.

摘要： A battery may include a first electrode and a second electrode having opposite polarities. The battery may include a separator interposed between the first electrode and the second electrode. The battery may further include a current interrupter configured to generate a liquid upon activation of a temperature trigger. The liquid may react with the first electrode and/or the second electrode to cause a decomposition of the first electrode and/or the second electrode. The decomposition of the first electrode may delaminate the first electrode from a first current collector coupled with the first electrode while the decomposition of the second electrode may delaminate the second electrode from a second current collector coupled with the second electrode. The delamination of the first electrode and/or the second electrode may generate at least one nonconductive gap that interrupts a current flow within the battery.
