Hard Carbon Networks for Mitigating Graphite Lattice Strain Under Extreme‑Low‑Temperature Fast Charging

ABSTRACT Low‐temperature fast charging of lithium‐ion batteries is primarily constrained by sluggish reaction kinetics and mechanical degradation of graphite anodes. Here, a kinetic–structural coordination strategy based on a 15 wt.% hard carbon (HC) percolating network embedded...
