Abstract
A high energy density, high power lithium metal anode rechargeable battery having volumetric energy density of >1000 Wh/L and/or a gravimetric energy density of >350 Wh/kg, that is capable of >1 C discharge at room temperature. In some embodiments, a high power lithium metal anode rechargeable battery of the present disclosure includes a lithium metal anode having a thickness of less than 20 μm and a ratio of anode capacity (n) to cathode capacity (p) in a discharged state, i.e., n/p, in a range of 0.8 to less than or equal to 1 or in a range of 0.9 to less than or equal to 1. In some embodiments, a high power lithium metal anode rechargeable battery of the present disclosure further includes a high-voltage cathode and a hybrid separator.
