Expanded graphite as superior anode for sodium-ion batteries.
Graphite, as the most common anode for commercial Li-ion batteries, has been reported to have a very low capacity when used as a Na-ion battery anode. It is well known that electrochemical insertion of Na(+) into graphite is significantly hindered by the insufficient interlayer spacing. Here we report expanded graphite as a Na-ion battery anode. Prepared through a process of oxidation and parti...
متن کاملAnode for Sodium-Ion Batteries
DOI: 10.1002/aenm.201500174 The continuous pulverization of alloy anodes during repeated sodiation/desodiation cycles is the major reason for the faster capacity decay. However, if these elements can form a compound (such as Sn 4 P 3 ) after each Na extraction, the pulverization of these elements can be partially repaired and the accumulation of pulverization can be terminated. Therefore, we ca...

Owing to almost unmatched volumetric energy density, Li-ion batteries have dominated the portable electronics industry and solid state electrochemical literature for the past 20 years. Not only will that continue, but they ar...
متن کاملDissolution and ionization of sodium superoxide in sodium–oxygen batteries
With the demand for high-energy-storage devices, the rechargeable metal-oxygen battery has attracted attention recently. Sodium-oxygen batteries have been regarded as the most promising candidates because of their lower-charge overpotential compared with that of lithium-oxygen system. However, conflicting observations with different discharge products have inhibited the understanding of precise...
متن کاملMicro-nano structure hard carbon as a high performance anode material for sodium-ion batteries
Superior first-cycle Coulomb efficiency (above 80%) is displayed by filter paper-derived micro-nano structure hard carbon, and it delivers a high reversible capacity of 286 mAh g-1 after 100 cycles as the anode for Na-ion battery at 20 mA g-1. These advantageous performance characteristics are attributed to the unique micro-nano structure, which reduced the first irreversible capacity loss by l...
