Abstract:Sodium ion batteries (SIBs) have drawn much attention as alternative charge carrier to lithium because of their abundance and cost‐effectiveness. However, SIBs are limited by their low capacity to achieve comparable loadings in graphite. Here, cyanographene and cyanographite are proposed as materials exhibiting superior storage capacity, facilitating sodium ionization. First principle calculations are performed to evaluate the sodium adsorption and diffusion of cyanographene and cyanographite. Calculation show… Show more
