Aqua Metals said today it has signed a letter of intent (LOI) with Taiwanese lead refining company, ACME Metal Enterprise, to deploy its lead battery recycling technology at a facility in Keelung.

The companies also intend to develop a process to convert briquettes fabricated with the AquaRefining technology directly into battery-grade lead oxide using a ball mill.

Aqua Metals said the LOI gives both sides 60 days to finalise a definitive agreement, including terms for licensing and a phased deployment of the AquaRefining equipment – with a "global battery manufacturer” to be named at a later date.

ACME currently refines lead bullion into lead alloys for sale to global battery producers.

'Special opportunity'

Aqua Metals said it has already converted briquettes into lead oxide using the Barton pot (melting) method. The addition of the ball mill, or grinding process, would give the partners the potential to produce oxide using the only two industry standard processes available.

Aqua Metals president and CEO Steve Cotton said: "The added value of potentially strengthening our intellectual property related to oxide manufacturing and the ability to offer our clients the technology to create oxide directly from AquaRefined briquettes, using both industry standard methods, makes this a special opportunity for Aqua Metals.”

ACME’s MD, Linus Lu, said the partnership would allow his company to expand its dealings with large battery manufacturers and establish itself "as the first green tech lead recycler in Asia”.
