Abstract:<\/h4>\n
Abstract Calcium ion batteries (CIBs) are considered as an important candidate for post\u2010lithium energy storage devices due to their abundance of resources and low cost. However, CIBs still suffer from slow kinetics due to the large solvation structure and high desolvation energy of Ca 2+ ions. Here, a solvation regulation strategy based on donor number (DN) is reported to achieve easy\u2010desolvation and rapid storage of Ca 2+ in sodium vanadate (Na 2 V 6 O 16 \u00b72H 2 O, NVO). Specially, the solvent with a low DN, represented by propylene carbonate (PC), forms the first solvation shell of calcium ions with weak binding energy and small shell structure, which facilitates the migration of Ca 2+ in the electrolyte. More importantly, the low DN solvent is preferentially desolvated at the cathode\/electrolyte interface, promoting the insertion of Ca 2+ into the NVO electrode. Mechanism studies further confirm the highly reversible uptake\/release of Ca 2+ in the NVO cathode, along with the V\uf8ffO distance change in the coordination structure. Therefore, the NVO cathode achieves high capacity (376 mAh g \u22121 at 0.3 A g \u22121 ) and high\u2010rate performance (151 mAh g \u22121 at 5 A g \u22121 ). The weak solvation effect strategy further improves the electrochemical performance and provides great importance for the design of the long\u2010term development of CIBs.<\/p>\n","protected":false},"excerpt":{"rendered":"
