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 together with his analysis funding.
“It was a bizarre scenario the place I felt a little bit bit powerless — once more. I assumed, ‘If I don’t create a possibility for myself, I’m performed,’” he mentioned.
Harter had been in difficult spots earlier than. A primary-generation school scholar from the native Tennessee hamlet of Walland, Harter was chosen for an ORNL robotics internship in 2016 that helped pay his means by means of close by Pellissippi State Group Faculty. When the internship ended, he needed to persuade his ORNL supervisor to fund him for the primary time by means of one other internship.
It labored, and Harter has continued tackling robust challenges at ORNL ever since. His initiative and perseverance have incessantly enabled him to show useless ends into potentialities. Immediately he’s a technical skilled within the Vitality Science and Expertise Directorate, specializing in electronics recycling and high-voltage applied sciences.
“I knew I might be taught rapidly. I simply wanted a number of folks to consider in me and belief me to do essential issues,” mentioned Harter. “If you happen to 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 creating automation processes and controls for recovering important supplies from laborious drives and electrical car, or EV, batteries. Harter credit McIntyre with offering him alternatives as an intern for significant duty and analysis, together with creating tasks and inventing disassembly strategies and processes.
After Harter turned 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 corporations to be taught extra about their wants, the know-how they could undertake and particulars of their enterprise operations. In lots of circumstances, corporations indicated they have been shredding total batteries or laborious drives for disposal with out separating parts for reuse.
Automated disassembly is safer and improves the standard and worth of extracted supplies equivalent to copper and aluminum. “We like to speak about recovering the worth as a substitute of recycling,” mentioned Harter, who earned two patents within the course of.
McIntyre and Harter demonstrated the quick, environment friendly restoration of uncommon earth magnets from laborious drives for direct reuse, which is the aim for each profitability and environmental profit. In addition they developed automated processes to recuperate supplies and parts from EV drivetrains and automotive lithium-ion batteries. The guts of the method is a big six-axis industrial robotic arm with customized tooling. The duo selected an older, off-the-shelf robotic to indicate that the method may very well be reasonably priced for scrap outlets, enabling extra widespread adoption of superior recycling. The robotic’s pivoting, shiny 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 shield employees 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 school 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 monitor to switch to the College of Tennessee.
He persevered, enjoying 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 venture studies when he acquired the decision from Madhu Chinthavali, then a bunch chief in ESTD. Chinthavali had taken observe of Harter’s initiative and supplied him the possibility to attempt a brand new analysis course.
“He learns quick,” mentioned Chinthavali, now head of the Vitality Programs Integration and Controls Part. “This setting 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 take a look at mattress for grid methods parts and including automation capabilities to the Grid Analysis Integration and Deployment Middle, or GRID-C. However he additionally helped arise the ability throughout 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 area and invent new know-how,” mentioned Harter, who has additionally labored jobs in building, reworking and carpentry. “I can take the initiative to pursue the issues I would like.”
Now a technical skilled after finishing his bachelor’s diploma final 12 months, Harter is recycling his personal expertise by making use of his high-voltage data to automation. Immediately he leads a multifaceted new collection of tasks associated to automated recycling of lithium-ion batteries, which is significant 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 hundreds inside a single EV battery stack. And since used batteries typically nonetheless retain helpful capability — even when not sufficient to run a automotive — Harter is creating strategies for combining them to construct residential vitality storage models. These battery clusters might present a secondary house vitality supply when excessive demand causes a spike in electrical energy costs, equivalent to throughout warmth waves.
“I’m excited that automated battery disassembly is lastly beginning to be acknowledged extra extensively as an essential alternative,” Harter mentioned. “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 all the time felt fallacious — and it was all the time robust to resolve what we must always put behind there. In concept, your most unique and finest 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 …
