Nitrogen doped SnO 2 polycrystalline nanostructures were produced from commercial SnO powders in a new system that combines a low‐temperature plasma with heating. The method has the potential to improve the initial efficiency and the cycling performance of SnO 2 anodes in Li‐ion batteries. With this system, the temperature of the SnO to SnO 2 conversion was lowered from 430 to 320 °C, up to 5 at% of doped nitrogen was detected and a nano‐scale polycrystalline structure was observed in the product. Combining heat and low‐pressure plasma is a promising approach for the production and treatment of enhanced energy storage materials.
