Recycling Revival: Inventive Drawback-Fixing For EV Battery Recycling


After being stabilized in an ambulance as he struggled to breathe, Jonathan Harter hit a low level. It was 2020, he was very sick with COVID-19, and his job as a lab technician at Oak Ridge Nationwide Laboratory was ending alongside along with his analysis funding.

“It was a bizarre scenario the place I felt just a little bit powerless — once more. I assumed, ‘If I don’t create a possibility for myself, I’m carried out,’” he stated.

Harter had been in difficult spots earlier than. A primary-generation faculty scholar from the native Tennessee hamlet of Walland, Harter was chosen for an ORNL robotics internship in 2016 that helped pay his manner by close by Pellissippi State Group School. When the internship ended, he needed to persuade his ORNL supervisor to fund him for the primary time by one other internship.

It labored, and Harter has continued tackling powerful challenges at ORNL ever since. His initiative and perseverance have incessantly enabled him to show lifeless ends into prospects. At the moment he’s a technical skilled within the Power Science and Expertise Directorate, specializing in electronics recycling and high-voltage applied sciences.

“I knew I might be taught rapidly. I simply wanted a couple of folks to consider in me and belief me to do vital issues,” stated Harter. “For those who throw me into the hearth, I determine it out.”

The primary at hand Harter a giant task was now-retired ORNL senior researcher Tim McIntyre, who was growing automation processes and controls for recovering vital supplies from exhausting drives and electrical automobile, or EV, batteries. Harter credit McIntyre with offering him alternatives as an intern for significant accountability and analysis, together with growing tasks and inventing disassembly strategies and processes.

After Harter grew to become a lab technician, McIntyre helped him enhance his technical communication expertise by sharing presentation and reporting duties. McIntyre inspired Harter to behave as a liaison with recycling firms to be taught extra about their wants, the know-how they may undertake and particulars of their enterprise operations. In lots of instances, firms indicated they have been shredding whole batteries or exhausting drives for disposal with out separating parts for reuse.

Automated disassembly is safer and improves the standard and worth of extracted supplies reminiscent of copper and aluminum. “We like to speak about recovering the worth as an alternative of recycling,” stated Harter, who earned two patents within the course of.

McIntyre and Harter demonstrated the quick, environment friendly restoration of uncommon earth magnets from exhausting drives for direct reuse, which is the purpose for each profitability and environmental profit. Additionally they developed automated processes to recuperate supplies and parts from EV drivetrains and automotive lithium-ion batteries. The center of the method is a big six-axis industrial robotic arm with customized tooling. The duo selected an older, off-the-shelf robotic to point out that the method may very well be reasonably priced for scrap outlets, enabling extra widespread adoption of superior recycling. The robotic’s pivoting, vivid blue arm, with an “elbow” that bends above Harter’s head, is guided by a controller and machine imaginative and prescient because it unscrews the bolts on an energized EV battery meeting.

For Harter, who takes all the security coaching he can, working with the automated robotic was interesting partly as a result of its use might defend staff in salvage yards and upkeep outlets from dealing with harmful voltages.

Harter nonetheless hadn’t given up on the classroom. Academic and profession steerage throughout highschool and faculty have been scarce. Though he had accomplished affiliate’s levels in electrical engineering know-how and industrial automation, Harter found he had not been in the appropriate educational observe to switch to the College of Tennessee.

He persevered, taking part in catch-up by taking extra programs whereas working full time. However then the automation tasks started winding down and McIntyre retired. That’s when Harter got here down with COVID whereas contemplating job choices. He was ending mission studies when he obtained the decision from Madhu Chinthavali, then a gaggle chief in ESTD. Chinthavali had taken word of Harter’s initiative and supplied him the possibility to strive a brand new analysis course.

“He learns quick,” stated Chinthavali, now head of the Power Techniques Integration and Controls Part. “This surroundings wants folks like him, as a result of when analysis morphs, he has the aptitude and mindset to adapt to these wants and take full possession of the issues he’s answerable for.”

Engaged on energy electronics, Harter started making a check mattress for grid methods parts and including automation capabilities to the Grid Analysis Integration and Deployment Middle, or GRID-C. However he additionally helped rise up the ability through the COVID shutdown with the assistance of only some colleagues working on-site.

“That’s what’s actually enjoyable about this place: I get to do some grunt work, which I get pleasure from, and I additionally get to develop lab house and invent new know-how,” stated Harter, who has additionally labored jobs in development, reworking and carpentry. “I can take the initiative to pursue the issues I need.”

Now a technical skilled after finishing his bachelor’s diploma final yr, Harter is recycling his personal expertise by making use of his high-voltage information to automation. At the moment he leads a multifaceted new sequence of tasks associated to automated recycling of lithium-ion batteries, which is important to making sure environmental profit all through their life cycle and past.

For instance, Harter is specializing in superior diagnostics to establish particular person or failing cells among the many a whole lot to 1000’s inside a single EV battery stack. And since used batteries usually nonetheless retain helpful capability — even when not sufficient to run a automobile — Harter is growing strategies for combining them to construct residential power storage items. These battery clusters might present a secondary house power supply when excessive demand causes a spike in electrical energy costs, reminiscent of throughout warmth waves.

“I’m excited that automated battery disassembly is lastly beginning to be acknowledged extra broadly as an vital alternative,” Harter stated. “I can’t wait to develop new tooling to defeat sure becoming a member of applied sciences, take batteries aside actually quick, and put collectively all of the automation items. That’s going to be enjoyable.”

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, however it at all times felt flawed — and it was at all times powerful to determine what we must always put behind there. In principle, your most unique and greatest content material goes behind a paywall. However then fewer folks learn it! We simply don’t love paywalls, and so we have determined to ditch ours.

Sadly, the media enterprise remains to be a troublesome, cut-throat enterprise with tiny margins. It is a unending Olympic problem to remain above water and even maybe — gasp — develop. So …
