An anode-free rechargeable battery is disclosed. The battery includes an anode current collector and a cathode containing an active cation M, where n=1, 2, or 3. The anode-free rechargeable battery further includes a separator placed between the anode current collector and the cathode. The anode-free rechargeable battery also includes an electrolyte including a salt or salt mixture containing an active cation Mdissolved in a solvent or solvent mixture.

Anode-free rechargeable battery

Embodiments of a non-aqueous electrolyte for a rechargeable sodium (Na)-based battery comprise a sodium salt and a nonaqueous solvent, the electrolyte having a sodium salt concentration &#x2265;2.5 M or a solvent-sodium salt mole ratio &#x2264;4:1. Na-based rechargeable batteries including the electrolyte exhibit both high cycling stability and high coulombic efficiency (CE). Some embodiments of the disclosed batteries attain a CE&#x2265;80% within 10-30 charge-discharge cycles and maintain a CE&#x2265;80% for at least 100 charge-discharge cycles. In certain embodiments, the battery is an anode-free battery in the as-assembled initial state.
