''The new '''lithium sulphur''' batteries promise the highest performance to weight ratio.''
=== [https://en.wikipedia.org/wiki/Lithium-ion_battery#Shapes|formes] ===
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)
