February 28, 2019: Hammond, the US-headquartered supplier of lead battery additives, has unveiled an entirely new oxide-making process, HALO, which should go live in March.
The system — it stands for Hammond Advanced Leady Oxide — re-invents how oxides are produced and can control particle size and the amount of free lead produced, president and CEO Terry Murphy told BESB.
Murphy said the new “Barton-Like” process is an entirely new system that can control particle size and the amount of free lead produced. It will allow for oxides to be tailored for specific battery configurations at less cost and with far greater control, he said.
“We’ll have a new centre-line machine going into production next month,” Murphy told BESB. “No one else has anything that looks like this.
The HALO process could become another tool in the battery manufacturer’s toolkit, said Murphy.
“Right now, making oxide is hard to do,” he said. “It’s capital intensive, and it’s not as controlled as it should be. We think that we can do a better job in controlling it. Current variations in the oxide production process are corrected in the down-stream processes, so we think that producing to a tighter specification would allow our customers, the battery manufacturers, to shorten curing their times. We have also proven that we can tailor the “free lead”, so we think we can make better red lead, better litharge, and tailor everything else in between.
“It’s mainly about achieving cost reduction in downstream process, optimizing the oxide, the “free-lead”, for a particular battery configuration, but there may also be some untapped potential in performance as well,” he says.
“The bottom-line message is we are 100% committed to tailoring oxides just as we tailor expanders.That’s our goal.”
