Alkaline cell

The common 1.5 V single-use cell, with a zinc negative electrode and manganese dioxide positive in potassium hydroxide electrolyte. It is the reference point for most people’s idea of a battery, and is not rechargeable.

Aqueous battery

Any battery whose electrolyte is water-based, from lead–acid and nickel–metal hydride to aqueous zinc-ion and sodium-ion designs. Water is cheap, non-flammable and highly conductive, but it splits at 1.23 V in theory and around 2 V in practice, which caps cell voltage and energy density.

Dendrite

A tree-like metal deposit that can grow from the negative electrode through the separator, raising self-discharge or causing an internal short circuit.

Nickel–zinc battery

An alkaline rechargeable cell with a nickel oxyhydroxide positive and zinc negative, giving about 1.6 V — more than NiMH — with good power and no flammable electrolyte. Zinc dissolves and redeposits unevenly, changing shape and growing dendrites, which limits cycle life; it is used in AA cells and in high-power backup supplies for data centres.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.
