A type of basic, as opposed to acidic, substance; in batteries, it refers to a type using alkaline electrolytes such as potassium hydroxide, known for long life and steady power output.

P-Type

A type of semiconductor material that is doped with elements which create excess positive charge carriers or holes.

N-Type

A category of semiconductor material where the charge carriers are predominantly electrons, achieved by doping the material with elements having more valence electrons than the semiconductor.
