摘要: Abstract Three-dimensional (3-D) current collectors in lithium-ion batteries with high areal loading of cathode materials enables reduced packaging weight and cost compared to planar collector materials. Here, we demonstrate the use electrophoretic deposition (EPD) as a route prepare thick assembles 3-D scaffolds using LiFePO4 loadings measured from 2 mg/cm2 up 20 mg/cm2 conductive carbon cloth Our findings cathodes capacity ∼2.4 mAh/cm2 minimal decay (
