Dry-processed thick electrode design with a porous conductive agent enabling 20 mA h cm ⁻² for high-energy-density lithium-ion batteries

Dry-processed thick cathodes designed with a porous spherical conductive agent exhibit superior electrochemical performances, even with high areal capacities of up to 20 mA h cm −2 and a high composite density of 3.65 g cm −3 .
