Abstract
A lithium-ion battery includes an electrode with a plurality of channels formed at least partially through its thickness. Each channel has a diameter in a range from 5 μm to 100 μm and/or is spaced apart from another channel by a distance in a range from 10 μm to 200 μm as measured between centerlines of the channels. The electrode may be an anode and includes carbonaceous material such as graphite and/or additional electrochemically active lithium host materials. The battery can be charged at a C-rate greater than 2 C.
