Relectrify technology brings new life to old lithium-ion batteries

Melbourne-based company Relectrify is developing and commercialising control technology that unlocks extra performance in battery systems by boosting their second-life storage capability and lifespan once they are no longer effective as electric vehicle or plug-in hybrid car batteries.

Relectrify's technology focuses on providing an affordable, sustainable energy storage alternative by giving the batteries in today's electric cars the potential to power households tomorrow.

Battery packs that are no longer useful in vehicles often still have around 80 per cent of their capacity, but if there's one weak cell, it impacts the ability of the entire battery.

Relectrify's technology identifies the weaker cells and then draws more energy from the stronger cells and less energy from the weaker cells.

This unlocks capacity that can be then used in other applications, such as batteries for household purposes or motorhomes and recreational vehicles that use batteries when external power is not available.

Relectrify, which was founded in 2015, is an alumni of the University of Melbourne's accelerator program. It was one of 10 start-up companies which pitched their projects at the Clean Energy Innovation Fund's inaugural Clean Energy Innovators Demo Day in February 2017.

Relectrify had its technology validated by CSIRO last year, and had been recognised as a leading innovator by Tech23 and Falling Walls Germany.

In December 2018, Relectrify announced a collaboration with Nissan Motor and Sumitomo subsidiary 4R Energy Corp to deliver battery storage products.

The Clean Energy Finance Corporation through the Clean Energy Innovation Fund is committing $750,000 equity to Relectrify to help "prove" the business with further development of the technology and initial trials.  The investment is part of a $1.5m pre-Series A equity raising by Relectrify.
