Biomass-derived carbon materials have been considered as the likely next-generation anodes for safe and sustainable post-lithium-ion technology [1,2]. Hard carbon is recognized as the most promising anode candidate for Na-ion batteries due to its highly disordered structure and suitable interlayer spacing for the insertion of large amounts of Na-ions. Herein, a series of hard carbon (HC) samples was synthesized by the simple and effective route including carbonization of viticulture industry byproduct – vine shoots (VS) at different temperatures ranging from 700 to 1600 ℃. All materials were examined as electrodes for Na-ion rechargeable batteries using a coin cell configuration. The temperature influence on the Na storage behavior in an organic electrolyte was investigated at different currents in terms of irreversible capacity loss in the first cycle, its correlation with material porosity and cycling stability. Relations between Na storage performance and the structural/textural properties of carbon will be presented and discussed. The optimal conditions for obtaining high-quality and sustainable hard carbon will be revealed to show possible directions toward the simple design of a high-performance HC anode for Na-ion rechargeable batteries.
