Abstract
Introducing bimodal porous current collector with high open porosity and good mechanical stability has been expected to be a very effective approach to improve the areal capacity and cycling performance of Sn anode for lithium ion batteries. In this study, a novel 3D bimodal porous current collector with large interconnected spherical channels of 100-200â¯Î¼m and nano-pores of 100-150â¯nm was fabricated by molten-metal infiltration and dealloying. It is found that Sn coated bimodal porous composite electrodes with good mechanical stability can exhibit higher areal capacity and cycling stability than other bimodal porous electrodes and the planar electrodes.
