Abstract
Lithium-ion battery with high Li+ flux transferability is a key direction in the field of clean energy. However, with small thickness, commercial polyolefin separators own low porosity to ensure sufficient thermomechanical properties, resulting in tortuous and enlarged Li+ diffusion pathways that induce large overpotentials and detrimental dendrite growth. This research (DOI: 10.1002/elt2.1) introduces a ∼3-μm ultralight PTFE matrix (UP3D) separator and describes its design principle and mechanism. Results show that the UP3D separator has a high Li+ flux transferability and strong mechanical properties, which reflects its promising potential in high-flux battery applications.
