Lithium-boron battery using ammonia as a fluid agent. High-power battery for endurance use or igniting fusion devices. Higher power density than current lithium-air batteries. Terminals are lithium and carbon. A 1kg closed cell battery should hold about 10 amp-hours of charge and produce 16 volts. As with all lithium batteries, it will need to be recycled as it begins to wear out.
Vanadium-sulfur using acetic acid (purified vinegar, molar density 1.104). Carbon and copper terminals. Can be a flow battery or closed cell. Medium-power battery for long-term endurance use. High power density compared to vanadium and sulfuric acid. A 1kg closed cell battery should hold about 17 amp-hours and produce about 10 volts. This battery will last an extremely long time, about twice the durability of lead-acid marine batteries.
Vanadium-tin battery using a mild acid like vinegar or lemon juice. Low-power battery for long-term use. Terminals are tin and carbon. Not rechargeable (tin is a bit crumbly). A 1kg battery (always closed cell) will hold about 2 amp-hours and produce about 2 volts. Recommended to use only with low-power and/or short-term devices, typically with a charging circuit for an on-board capacitor in the device for burst usage.
In both vanadium batteries, use vanadium dust, not vanadium plates.
