Also sodium ions prefer octahedral and prismatic sites [7] compared to octahedral and tetrahedral sites for lithium [8]. Carbon negative electrode (anode) materials are generally divided into three classes: graphite, non-graphitized glass-like carbon (hard carbon) which cannot be graphitized even when heat-treated at very high …

In a more practical design for lithium-ion batteries, a 70-80 μm electrode can still reach a discharge rate capability of 10 C. The useful charge rates are also comparatively high (1 C). The discharge rates of graphite electrodes are sufficient for use in lithium-ion batteries for automotive and similar applications.

2.1 Synthesis of peanut-shell-derived Hard carbon. As shown in Fig. 1, the peanut shells (collected from the farm in India as agricultural waste) were washed and ultrasonicated with tap water and de-ionised water (DI water) several times to remove dust, dirt, and other impurities.Then dried the peanut shells in a vacuum oven at 60 °C for 12 h. …
Graphite is the commercial anode for lithium-ion batteries; however, it fails to extend its success to sodium-ion batteries. Recently, we demonstrated that a low-cost amorphous carbon—soft carbon exhibits remarkable rate performance and stable cycling life of Na-ion storage. However, its Na-ion storage mechanism has remained elusive, …
