Abstract
A lithium-ion battery may include a cathode, an anode, and a polymer electrolyte. The anode may include a current collector. The current collector may include a metal oxide layer provided in a first pattern overlaying a metal layer. The anode may also include a patterned lithium storage structure. The patterned lithium storage structure may include a continuous porous lithium storage layer overlaying at least a portion of the first pattern of metal oxide. These and other lithium-ion batteries are described.
