Lithium-ion
https://en.wikipedia.org/wiki/Lithium-ion_battery
Handheld electronics mostly use LIBs based on lithium cobalt oxide (LiCoO2), which offers high energy density, but presents safety risks, especially when damaged.
Lithium iron phosphate (LiFePO4), Lithium ion manganese oxide battery (LMnO or LMO) and lithium nickel manganese cobalt oxide (LiNiMnCoO2 or NMC) offer lower energy density, but longer lives and inherent safety. Such batteries are widely used for electric tools, medical equipment and other roles. NMC in particular is a leading contender for automotive applications.
Lithium nickel cobalt aluminum oxide (LiNiCoAlO2 or NCA) and lithium titanate (Li4Ti5O12 or LTO) are specialty designs aimed at particular niche roles.
The new lithium sulphur batteries promise the highest performance to weight ratio.
Modèles de location
Puisque c'est un modèle commercial qui est pratiqué (en particulier s'agissant de certains véhicules électriques), il vaudrait la peine de le décrire/comprendre afin d'en tenir compte et de ne pas passer à côté de solutions économiquement intéressantes.
