Hollingsworth & Vose, a global leader in filtration and energy storage solutions, will be showcasing its PowerFill AGM lead-acid battery filling technology at ELBC this week.
The PowerFill was designed to solve the challenges of slow and uneven filling of the acid electrolyte by enhancing the surface of the separator to create open channels.
The open channels allow gas pockets to escape more easily from the battery during the acid filling process, thereby allowing acid to flow quickly and evenly into the centre of the plates and AGM separator.
The technology prevents a gas pocket from becoming trapped toward the centre of the plates and AGM separator— air and possibly CO2 generated by the reaction of the acid electrolyte— a key factor affecting the acid filling speed.
This improves acid concentration in the centre of the electrode and eliminates black or dry spots found in standard AGM separators.
The PowerFill patented technology can be applied to various types of AGM separators and replaces existing standard AGM separators.
The technology is best for tall industrial and commercial truck batteries that are difficult to fill as well as data centre, commercial truck, telecommunication and industrial truck applications.
H&V says the PowerFill has demonstrated a 50% reduction in acid filling time and demonstrated more than a 10% increase in battery capacity and cycle.
To hear more about PowerFill, Nicolas Clement will be presenting a paper: “PowerFill™ – A novel AGM separator improving acid filling and battery performance” in the supplier Forum on Wednesday 7th.
H&V will be exhibiting at Booth number 5.
