Na-ion batteries have been proposed as candidates for replacing Li-ion batteries. In this paper we examine the viability of Na-ion negative electrode materials based on Na alloys or hard carbons in terms of volumetric energy density. Due to the increased size of the Na atom compared to the Li atom, Na alloys would lead to negative electrode materials with roughly half the volumetric energy density of their Li analogs. Volumetric energy densities obtainable with sodiated hard carbons would also be significantly less than those obtainable with lithiated graphite. These findings highlight the need of novel ideas for Na-ion negative electrodes.

(2014, background): “To this end, researchers have proposed a number of high-capacity sodium host materials (negative electrode) involving either carbon or group IVA and VA elements that form intermetallic compounds with Na.(9-13) The alloying compounds demonstrate high first cycle Na-storage capacities, such as Na15Sn4”
- Electrospun Sb/C fibers for a stable and fast sodium-ion battery anode. (2013, background): “Since the sodium ion possesses a larger radius than the lithium ion, the effect of volume change upon sodiation/desodiation should be even more severe for the application of alloy-based materials in SIBs.(23) Thus, the development of stable alloy-based anode materials for SIBs became more challengin”
