An 18650 size lithium ion battery, with an alkaline AA for scale Cylindrical lithium-ion rechargeable battery Lithium-ion rechargeable batteries are generally not interchangeable with primary types using different chemistry, though certain lithium primary cell sizes do have lithium-ion rechargeable equivalents.
A lithium primary battery, not interchangeable with zinc types. A rechargeable lithium-polymer version is available in the same size and is interchangeable in some uses. According to consumer packaging, replaces (BR) 2 ⁄ 3 A. In Switzerland as of 2008, these batteries accounted for 16% of lithium camera battery sales.
A lithium polymer battery, or more correctly lithium-ion polymer battery, is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, like tablet computers, cellular telephone handsets and radio-controlled aircraft.
A nickel-cadmium battery (NiCd or NiCad) is a rechargeable battery used for portable computers, drills, camcorders and other small battery-operated devices requiring an even power discharge. NiCds use electrodes made of nickel oxide hydroxide, metallic cadmium and an alkaline electrolyte of potassium hydroxide.
