Abstract
Electric batteries are provided wherein the positively charged electrode contacts an aqueous layer containing material which is reduced during electric discharge and/or metal ions are transported through special electrolyte that inhibits dendritic deposition on the negatively charged electrode. Methods described include electrolyte compositions including organoborate anions and cations with low charge density, and aqueous solutions containing bromate and/or bromide anions and high concentrations of dissolved salts.
Claims19
An electric battery comprising in order:
- a negatively charged electrode, an electrolyte which directly contacts said negatively charged electrode, optional additional layers, and a positively charged electrode, wherein said negatively charged electrode contains at least 2% metallic sodium and/or metallic potassium by mass when the electric battery is fully charged which is active material that migrates towards the positively charged electrode as the electric battery is discharged, and wherein said electrolyte contains at least 100 μM of cations with lower charge density than cations of said active material, and wherein said electrolyte contains dissolved anions which are at least 50% organoborate anions by mass.
An electric battery comprising in order:
- a negatively charged electrode, optional additional layers, an electrolyte containing organic compounds, optional additional layers, an aqueous layer containing material which is oxidized as the electric battery is charged and reduced as the electric battery is discharged and further containing one or more dissolved salts which have high solubility in water and act to reduce solubility of water in an electrolyte layer of the electric battery, optional additional layers, and a positively charged electrode.
