Abstract

Lithium Iron Phosphate Cathodes Gradient porosity LiFePO4 electrode design facilitates Li-ion kinetics and electron transfer in high-energy-density Li-ion batteries. In article number 2500093, Ungyu Paik, Taeseup Song, Junghyun Choi and co-workers present a well-designed IPB (increasing porosity toward bottom) electrode with uniform binder distributions that enables facile Li-ion/electron transfer and easier electrode processing. This electrode design paves the way for cost-effective, high-energy-density Li-ion batteries.
