Aluminum-air battery

The aluminum-air battery, or Al-air battery, is a primary metal-air electrochemical cell that generates electricity by oxidizing an aluminum anode while drawing oxygen from surrounding air.

Aluminum-ion battery

An aluminum-ion battery is a rechargeable battery that uses a metallic aluminum anode with chloride-based electrolytes, promising high capacity and safety but not yet commercially viable.

Aluminum–sulfur battery

An aluminum–sulfur battery (Al–S battery) is a rechargeable battery pairing an aluminum anode with a sulfur cathode, typically in molten salt or ionic liquid electrolytes.

Aqueous zinc-iodine battery

An aqueous zinc-iodine battery is a rechargeable, water-based battery using zinc and iodine electrodes, valued for low cost and safety but limited by the polyiodide shuttle effect.

Aqueous zinc–manganese dioxide batteries

Aqueous zinc–manganese dioxide batteries are rechargeable batteries pairing a zinc metal anode with a manganese dioxide cathode in a water-based electrolyte such as zinc sulfate.

Metal–air battery

A metal–air battery is an electrochemical cell that oxidizes a metal anode while drawing its cathode oxygen from the air, giving it some of the highest theoretical energy densities of any battery family.

Molten-salt battery

A molten-salt battery is a battery using molten salt as an electrolyte, ranging from primary thermal cells to rechargeable types such as the sodium-sulfur and sodium-metal halide (ZEBRA) batteries.

Non-nucleophilic magnesium electrolytes

Non-nucleophilic magnesium electrolytes are liquid electrolytes for rechargeable magnesium batteries whose magnesium-carrying species do not attack electrophilic cathodes such as sulfur, unlike early Grignard-based electrolytes.

Organic radical battery

An organic radical battery (ORB) is a rechargeable battery that uses nitroxide radical polymers such as PTMA instead of lithium-ion intercalation, allowing very fast charging.
