Battery Chemistry Energy Density Chart

Battery technology has evolved tremendously since the introduction of the voltaic pile by Allesandro Volta in 1799,  experiments with different metals and electrolyte solutions have resulted in rechargeable chemistries we know and have used for many years such as: Lead Acid, Nickel Cadmium, Nickel Metal Hydride, and Lithium Ion. The goal from each advancement in chemistry technology is to make a smaller, lighter, more powerful and longer lasting battery design. This energy density chart shows the energy capability of each chemistry and demonstrates the advancement of each technology.
