''Li-ion cells (as distinct from entire batteries) are available in various shapes, which can generally be divided into four groups:''# ''Small cylindrical (solid body without terminals, such as those used in laptop batteries)''# ''Large cylindrical (solid body with large threaded terminals)''# ''Pouch (soft, flat body, such as those used in cell phones)''# ''Prismatic (semi-hard plastic case with large threaded terminals, such as vehicles' traction packs)'' https://en.wikipedia.org/wiki/Lithium_polymer_battery ''A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated variously as '''LiPo, LIP''', Li-poly and others), is a rechargeable battery of lithium-ion technology in a pouch format. Unlike cylindrical and prismatic cells, LiPos come in a soft package or pouch, which makes them lighter but also less rigid.'' ''"polymer" refers more to a "polymer casing" (that is, the soft, external container) rather than a "polymer electrolyte". While the design is usually flat, and lightweight, it is not truly a polymer cell, since the electrolyte is still in liquid form, although it may be "plasticized" or "gelled" through a polymer additive. These cells are sometimes designated as "LiPo"; however, from a technological point of view, they are the same as the ones marketed simply as "Li-ion", since the underlying electrochemistry is the same.'' ''The name "lithium polymer" (LiPo) is widespread among users of radio-controlled models, for which it may indicate a single cell or a battery pack with cells connected in series or parallel. The more general term "lithium-ion" (Li-ion) is used almost everywhere else, including consumer electronics such as mobile phones and notebook computers, and battery-powered electric vehicles.''
