''The new '''lithium sulphur''' batteries promise the highest performance to weight ratio.''

''Li-ion cells (as distinct from entire batteries) are available in various shapes, which can generally be divided into four groups:''

''[...] "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.''
