Critical overview of polyanionic frameworks as positive electrodes
Na-ion batteries (NIBs) are an important technological alternative to Li-ion batteries (LIBs) for developing energy storage systems that are cost-effective and less constrained by geographical supply chains, with similar energy densities. Analogous to LIBs, cathodes play a critical role in determining the energy density of NIBs, and layered transition
