A performance evaluation undertaken by Exponent Inc has revealed that EcoloCap’s Nano Lithium X Battery offers over 98 percent efficiency and has "the world’s highest energy density output per mass". Outperforming company expectations, the battery was also found to have the "fastest recharge time of any comparable commercial battery" together with the "lowest cost per energy output".
In the evaluation, engineering and scientific consultants Exponent Inc tested for the charge and discharge capabilities of the Nano Lithium X Battery from EcoloCap at 100 amps, 150 amps, 200 amps and 235 amps and, as you can see from the table below, its efficiency scored 98 percent or over in all but the last rate.
One 720Ahr/12V battery was used for the whole evaluation which saw it being hooked up to a 2005-S LEM current transducer to measure the current and having the temperature, voltage and current recorded using a Fluke Hydra Logger. The battery was discharged at a constant current until it dropped to 9V, then it was charged using an open circuit, 12.6V power supply set to the test charge current. Once fully charged, the Nano Lithium X was then tested whilst being discharged at the test current until it again dropped to 9V. Then it was retested at the next charge current until the evaluation concluded.
Ecolocap has compared its Nano Lithium X battery to Lithium-ion batteries and claims that its proven to have the highest energy density and the lowest cost per watt-hour. Commenting on the results, the company's Michael Siegel said: "This battery is well-positioned to become a leader in key markets seeking high-performance batteries, including use in electric vehicles, golf carts, cellular towers and similar demanding applications."
