Abstract

Producing hard carbon from lignocellulosic biomass has been the focus of recent studies as a promising source of anode material for Na-ion batteries. Woody biomass is a potential source, but it is already well valorised. Consequently, river driftwood can be an excellent alternative, especially since it is a disturbing waste for dam regulators.. It can jeopardize dam safety, damage intake works, and sink in reservoirs, lowering water quality and decreasing reservoir volume. We examine the potential of river driftwood as a source of hard carbon for Na-ion batteries. Hydrothermal carbonization (HTC) was carried out at temperatures between 180 and 220 °C as the first step to produce hydrochar followed by an upgrading pyrolysis step at 1400 °C under an inert atmosphere to obtain hard carbon. We investigated the effect of HTC operational conditions and driftwood biomass (genera) on hydrochar and hard carbon properties, as well as the latter's impact on Na-ion batteries. Anode delivered a reversible discharge of 270 to 300 mAhg-1 for the first cycle. Derived hard carbon had Coulombic efficiency of 77 to 83 % and a promising cyclability of maximum 2% loss after 100 cycles. Moreover, results suggest that obtained hard carbon can compete with commercial materials and is capable to supply large battery factories with anode material.
