Layered hydrotalcite derived holey porous cobalt oxide nanosheets coated with nitrogen-doped carbon for high-mass-loading Li-ion storage

Transition metal oxides are promising for Li-ion batteries but suffer from sluggish Li-ion storage in thick electrodes. This work achieves high-mass-loading Li-ion storage by forming holey porous structures in CoO nanosheets using layered hydrotalcites as starting materials.
