Kinetically fast charging lithium-ion battery

A battery comprising:

• a lithium-containing cathode material layer, wherein the lithium-containing cathode material layer is selected from a lithium-containing material containing grains having a grain size of less than 100 nm and a density of grain boundaries of 1010 cm−2 or greater, or a lithium-containing material having a columnar microstructure;
• an anode structure of unitary construction and including a non-porous region and a porous region comprising a top porous layer having a first thickness and a first porosity, and a bottom porous layer located beneath the top porous layer and forming an interface with the non-porous region, wherein at least an upper portion of the non-porous region and an entirety of the porous region are composed of silicon, and wherein the bottom porous layer has a second thickness that is greater than the first thickness, and a second porosity that is greater than the first porosity;
• and
• an electrolyte region located between the top porous layer of the anode structure and the lithium-containing cathode material layer.
