EcoloCap claims its battery technology more than 98% efficient
The Nano Lithium X Battery from EcoloCap
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."

pretty impressive charging a 750 Amp-hour battery in 3 and a half hours!
Hmmm, where they using a 120volt or a 240volt circuit to charge the battery on? Or, what was the charging current? They only say it was 12.6 volts. To charge a 750 Ah battery in 3 hours requires a heck of a lot of amps at the charging circuit!
Something doesn\'t smell right here as it\'s hard to believe it has 750amphrs.
With such amphrs the eff or charge.discharge rates are rather light being just .3 of it\'s rated cap or far less at 100 amps.
It\'s what can only be called puny for such a battery terminals is a joke.
we are Envision Energy Systems of Utah, we would like to test this battery in our new EV. can you give me a cost and when we could have them. can you give us the weight of the battery and size of the 235 battery.
the car we are building will have many new technologies that we will be testing. we are not sure of the voltage need yet, need to make changes in the motor first.
please contact Rocky Whitham at 801-232-0322 or email@example.com
Testing a 750Ah battery at 235A only represents a .3c load. In high end Radio control aircraft we are using LiPo and LiFePo4 battery packs that can deliver greater than constant 40c with burst current much higher than that. It is nice to see such big efficiencies, but show me a graph at 40c and then I\'ll get excited. Also, what charge rating do theses batteries have? We are charging our best packs at 5c and 6c rates. That means fully discharged to fully charged in 10-12 minutes. That is probably not feasible for a pack as large as 750Ah but I would like to know what they are rated at.
bet you can\'t say the name of this company 3 times without sputtering \"eco-clap\"
What\'s this battery\'s CCA rating?
okay, I want 20 of these batteries please
