Abstract Co‐free O3‐type NaNi 0.5 Mn O 2 cathode material for sodium‐ion batteries has shown great promise due to its high theoretical capacity and plentiful Na reservoir. However, the rapid recession caused by harmful phase transition large volume strain severely restricts their practical application. Herein, obstacle is well addressed constructing a P2&O3 biphasic structure via customized boron‐doping strategy. The light‐weight boron doping in interstitial position reduces energy gap of formation P2 O3 structure, which induces biphase state. In addition, exhibits near zero lattice interlocking effect P2&O3, as identified situ X‐ray diffraction measurement. As result, it presents remarkable cyclability with retention 85.2% over 1000 cycles at rate 5 C. More importantly, pouch‐type full‐cell device can exhibit long cycling life 70.8% 150 0.1 This work offer new inspiration designing advanced sodium electrode materials light element future storage devices.

Lignocellulosic biomass-derived pyrolysis hard carbon (LCB-HC) shows promising commercial potential as an anode material for sodium-ion batteries (SIBs). LCB compromises multiple biopolymer sources, including cellulose, hemicellulose, and lignin, which influence the formation microstructure of HC. However, poor plateau kinetics LCB-HC is one main obstacles that severely limits its energy density with high power density, could be attributed to narrow interlayer distance lack abundant closed pores intercalation/filling Na+. Herein, we proposed a bottom-up approach tailoring by regulating components precursor at molecular level using bioenzymes secreted lignocellulolytic bacteria. This mild efficient enzymatic hydrolysis pathway partially depolymerized biopolymers basswood specifically, thereby enabling construction small curved-graphite domain architecture increased enlarged LCB-HC, benefiting low-voltage Na+ storage accelerated kinetics. As result, basswood-derived HC delivers reversible capacity 366.4 mAh g–1 performed remarkable retainability proportion 74.3% even current 1000 mA g–1. Such microbial-chemistry-assisted provided insights into construct high-performance SIB materials.
