Abstract

A facile freeze tape casting (FTC) strategy is utilized to prepare bilayered 4 mAh cm^-2 high-loading LiNi_0.6Co_0.2Mn_0.2O₂ cathodes. The bottom layer is a conventional nonaqueous electrode, which has a dense structure for high-energy purposes. The top layer is prepared by the proposed FTC, exhibiting a porous feature for high-power requirement. With the assistance of FTC, the bilayered electrodes successfully deliver enhanced rate and cyclic performance due to the improved lithium-ion diffusion kinetics and pathways. Therefore, the proposed FTC strategy and its delivered electrodes are promising for energy- and power-density lithium-ion batteries, potentially enlightening the research and development of lithium-ion battery manufacturing.
