Why Lithium-ion?

First commercialized by SONY in 1991, lithium-ion battery technology has matured to the point where it is now being used in many applications previously dominated by other battery technologies, including every electric vehicle currently on the market, most notably Tesla. Li-ion batteries power cell phones, laptops and many smaller consumer devices.

Li-ion technology is a winner in terms of both power and energy. As the chart below indicates, Li-ion batteries have superior energy and power compared to older battery technologies – such as lead acid. This means that Li-ion provides greatly enhanced range/run-time and power in a smaller, lighter package.
