Abstract
An anode for a lithium metal battery includes a host structure configured to be between an anode current collector and a separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure has a void space of ≥60% and ≤80%. Another anode for a lithium metal battery includes a current collector, a separator, and a host structure between the current collector and the separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure is formed of fibers.
Claims17
An anode for a lithium metal battery, comprising:
- a host structure configured to be between an anode current collector and a separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure has a void space of ≥60% and ≤80%, wherein the host structure is a layer of material having columnar voids created through a thickness of the layer, each columnar void having a diameter of between 0.5 μm and 5 μm, inclusive.
An anode for a lithium metal battery, comprising:
- a current collector;
- a separator;
- and
- a host structure between the current collector and the separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure is formed of fibers and individual void spaces each have a diameter between 0.5 μm and 5.0 μm, inclusive.
