"UltraBattery" Lead-Acid Supercap Hybrid Battery Class

Postby tigerbay » Sun Mar 09, 2014 9:11 pm

Lead Acid batteries have been around for quite some time, are very cheap and easy to maintain - however, they still have many drawbacks compared to other, more expensive and complex battery technologies.
However last year, taking the information known about the newer makes of Super Capacitors and combining it with that of Lead Acid, Ecoult has announced what it believes is the breakthrough for a whole new generation of lead acid battery production, and boasting a claim that it will be “an attractive and cost-effective alternative to other advanced battery chemistries”:

"UltraBattery®: The New Dimension in Lead Acid Battery Technology
Hybrid Energy Storage

UltraBattery® is a completely new class of lead-acid technology: a hybrid, long-life lead-acid energy storage device containing both an ultracapacitor and a lead-acid battery in a common electrolyte.

The breakthrough energy storage technology combines the advantages of the most tried and tested advanced rechargeable lead-acid battery technology with the advantages of an ultracapacitor. UltraBattery® enables an optimal balance of an energy-storing lead-acid battery with the quick charge acceptance, power discharge, and longevity of a capacitor.
High Efficiency and Cycle Endurance in Partial State of Charge Use

Standard valve-regulated lead-acid (VRLA) batteries can form ‘hard’ lead sulphate deposits inside the negative plate when operated continuously in a Partial State of Charge (PSoC) regime, unless given frequent refresh overcharge cycles. The Ultracapacitor integrated in the UltraBattery® chemistry modifies the process associated with the formation and dissolving of sulphate crystals in the negative plate when charging and discharging. This enables the UltraBattery® to operate with high efficiency in Partial State of Charge use.

Combined with the cycling endurance of the technology, UltraBattery’s® high efficiency in a PSoC results in an ability to process a much greater amount of energy in the device’s usable lifetime – a significant multiple over standard VRLA battery technology. The ability of UltraBattery’s® to process more energy, more quickly and for longer than a VRLA battery is fundamental to the typical grid and renewables requirements for smoothing the variability and shifting of energy.

Proven Outperformance of UltraBattery®

With its high cycling life, high conversion efficiency and low operating costs, UltraBattery® offers an economical $/kWh solution for whole of life for continuous regulation services and intermittency control. As the new dimension in lead-acid battery technology, it is safe, recyclable and produces virtually zero emissions. UltraBattery® is the economic and environmentally sound alternative to conventional generation assets. The outperformance of UltraBattery® across a range of key performance parameters has been proven in multiple tests by Sandia National Laboratory, the Advanced Lead Acid Battery Consortium (ALABC), CSIRO, Furukawa Battery, East Penn Manufacturing and Ecoult. UltraBattery® takes charges faster, lasts longer, and is more reliable in a string than any competing best-performing VRLA battery.
UltraBattery® – Versatile Energy Storage Technology

Invented by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia’s national science agency, UltraBattery® is a flexible energy storage battery technology suitable for multiple uses: automotive (such as hybrid electric vehicles), motive and stationary (such as renewable energy) applications.

"UltraBattery® Energy Storage:
The New Dimension in Lead Acid Battery Technology

UltraBattery® is a hybrid, long-life lead-acid energy storage device. It combines the fast charging rates of an ultracapacitor technology with the energy storage potential of a lead-acid battery technology in a hybrid device with a single common electrolyte.

Combining these two technologies in one cell means that UltraBattery® works efficiently in a Partial State of Charge (PSoC).

Compared with conventional VRLA batteries, UltraBattery® provides more energy and costs less over its lifetime when used in variable power applications. The technology is more efficient, and is also safe and recyclable.

UltraBattery® technology is already successfully deployed in automotive and stationary energy applications."

Are they available for purchase?
Where?
At which cost?

Would they perform better than lead-crystal batteries or TPPL (Tin Plates Pure Lead) batteries?

They don't seem to say as such - though the Chinese seem to in a google search make a supposed "ultrabattery" and sell them through things like Alibaba or wholesalers websites, though I'm not sure whether they are the same (or indeed the performance of such devices and hence unless another BVS member has accessed such technology, not sure whether a comparison can be made for the time being)
