Suppressing Lignin Self‐Condensation Enables Microstructure Engineering of Bamboo Derived Hard Carbon for High Performance Sodium‐Ion Batteries

at 6 C and superior cycle stability with a capacity retention of 93.97% after 2000 cycles at 2 C. This work not only unravels the mechanisms of efficient delignification at molecular level but also proposes a novel strategy to produce high-performance hard carbon from lignocellulosic biomass.
