Detailed Description for Ultra Battery

        ·         Ultra Battery is a hybrid device that combines ultra-capacitor technology with lead-acid battery technology in a single cell with a common electrolyte.UltraBattery® technology is already successfully deployed in automotive and stationary energy applications.

·         Physically, Ultra Battery has a single positive electrode and a twin negative electrode – one part carbon, one part lead, in a common electrolyte. Together these make up the negative electrode of the Ultra Battery unit, but specifically the carbon is the electrode of the capacitor and lead is the electrode of the lead-acid cell. The single positive electrode (lead oxide) is typical of all lead acid batteries and is common to the lead acid cell and the ultra-capacitor.

·         This technology (specifically the addition of the carbon electrode) gives Ultra Battery different performance characteristics to conventional VRLA batteries. In particular, Ultra Battery technology suffers significantly less from the development of permanent (or hard) sulfation on the negative battery electrode – a problem commonly exhibited in conventional lead acid batteries.

·         Ultra Battery is a hybrid, long-life lead-acid energy storage device. It combines the fast charging rates and longevity of an ultra-capacitor technology with the energy storage potential of a lead-acid battery technology in a hybrid device with a single common electrolyte.

 

Applications of Ultra Batteries:-

Multi-Purposing of Data Centres:-

·         Ultra Battery can be used to backup an uninterruptible power supply (UPS). In conventional UPS systems, the batteries sit, essentially unused, until a grid outage event occurs. Because the Ultra Battery can provide frequency regulation and related grid services, it can generate revenue for the UPS asset owner at the same time as providing backup power.

 

Grid Services:-

·         Ultra Battery can manage variability on electricity grids in five main ways: frequency regulation, renewable energy integration (smoothing and shifting), spinning reserve, ramp-rate control, and power quality and weak grid support.

 

Ramp-rate control for distributed storage:-

·         Many small-scale deployments of rooftop photovoltaic panels tend to multiply the effect of the intermittency of solar generation – creating a problem for grid operators. [REF] Ultra Battery energy storage has been used to reduce renewable intermittency by ramping the power on the electricity grid in a controlled manner, making renewable-generated power more predictable.

 

Power quality and weak grid support:-

·         Ultra Battery can also be used for demand management, which addresses the problems of grid supply and demand, but not necessarily those related to renewable intermittency. At the periphery of large grids, or on old grid infrastructure – such as single-wire earth return networks – the effect of a demand spike or variance in supply can be amplified because of its scale relative to other local activity. Ultra Battery can reduce these effects and ensure power quality from the grid for local users.

 

Standards & Safety:

·         Ultra Battery’s electrolyte solution contains H2SO4 in water, and its lead electrodes are inert. As the electrolyte is largely water, Ultra Battery is fire retarding. Ultra Batteries have the same transport and hazard restrictions as conventional VRLA batteries.

 

Recycling:-

·         Every part of each Ultra Battery – lead, plastic, steel and acid – is virtually 100% recyclable for later reuse. Large-scale recycling facilities for these batteries are already available and 96% of lead acid batteries used in the US are recycled. [30] Battery manufacturers recover and separate the lead, plastics and acid from VRLA batteries. The lead is smelted and refined for reuse. Plastic parts are cleaned, ground, extruded and moulded into new plastic parts. The acid is reclaimed, cleaned and used in new batteries.
