Precisely Tunable Instantaneous Carbon Rearrangement Enables Low‐Working‐Potential Hard Carbon Toward Sodium‐Ion Batteries with Enhanced Energy Density

As the preferred anode material for sodium-ion batteries, hard carbon (HC) confronts significant obstacles in providing a long and dominant low-voltage plateau to boost the output energy density of full batteries. The critical challenge lies in precisely enhancing the local graphitization degree to minimize Na
