摘要： The present invention discloses an iron-based cathode material for a sodium-ion battery, which comprises a Na3Fe2(SO4)3F material and a carbon-based material embedded into the bulk structure of Na3Fe2(SO4)3F material. The weight percentage of the carbon-based material is ranked between 1% and 10%. The present invention also provides a method for preparing the above-mentioned iron-based cathode material for a sodium-ion battery, and a corresponding sodium-ion full battery using the Na3Fe2(SO4)3F-based cathode material. The Na3Fe2(SO4)3F cathode material ensures desired electrochemical sodium storage performance, involving high specific sodium storage capacity, improved cycle stability and superior rate performance in comparison with that of various pristine NaxFey(SO4)z materials. The actual operating potential of the reported sodium-ion full battery in the present invention is significantly higher than the output potential of existing commercial sodium-ion full batteries, and the increase in battery energy density is also achieved.

摘要： An electrolyte includes a fluorinated cyclic carbonate, a multi-nitrilemulti-nitrile compound having an ether bond and a cyclic carbonate having a carbon-carbon double bond. Based on a total weight of the electrolyte, a weight percentage (Cf) of the fluorinated cyclic carbonate is greater than a weight percentage (Cn) of the multi-nitrilemulti-nitrile compound having an ether bond. The electrolyte can control the expansion of the electrochemical device, so that the electrochemical device has excellent cycle, storage and/or floating-charge performance.
