   en.wikipedia.org/wiki/Electric_vehicle_battery

   An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Compared to liquid fuels, most current battery technologies have much lower ...

   en.wikipedia.org/wiki/Nine-volt_battery

   The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3, introduced for early transistor radios.

   Compared to older battery types such as lead-acid batteries. Lithium-ion batteries for example now have an energy density of 0.9–2.63 MJ/L whereas lead-acid batteries had an energy density of 0.36 MJ/L (so 2.5 to 7.3x higher). There is still a long way to go if comparing it to petroleum-based fuels and biofuels, however (gasoline having an ...

6. Lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-ion_battery

   A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

   Before lithium-ion: 1960-1975. 1960s: Much of the basic research that led to the development of the intercalation compounds that form the core of lithium-ion batteries was carried out in the 1960s by Robert Huggins and Carl Wagner, who studied the movement of ions in solids. [1] In a 1967 report by the US military, plastic polymers were already ...
