Metal-organic framework electrodes for sodium ion batteries

DWPI Title: Sodium ion battery e.g. coin cell battery, under charging causes positive sodium ions to deintercalate from cathode to anode through ion-conductive electrolyte and discharging causes few of sodium to migrate from anode to cathode
Abstract: A sodium ion battery comprises a cathode having a porous redox active metal-organic framework material. The battery can be an organic electrolyte sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an organic solvent or mixture of organic solvents. Alternatively, the battery can comprise an aqueous sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an aqueous solvent. Battery performance is especially related to electrolyte and binder selection.
Use: Sodium ion battery e.g. coin cell battery (claimed).
Advantage: The sodium ion battery is economical and safe. The battery has long life cycle and round-trip energy efficiency and needs minimum maintenance.
Novelty: Sodium ion battery e.g. coin cell battery comprises a cathode comprising a porous redox active metal-organic framework (MOF) material comprising redox active metal center and organic linker, an anode and an ion-conductive electrolyte between anode and cathode. The charging of the battery causes positive sodium ions to deintercalate from cathode to anode through ion-conductive electrolyte and discharging causes few of sodium to reversibly migrate from anode and intercalate back into the cathode.
