K-BATTERY SHOW 2026, a Korean battery industry trade show held August 19–22, gave two startups their first real public exposure. Thot showed a robot called “Dismantlebot” built to automate the disassembly of retired EV batteries. Barkroad showed a battery pack reconfigured from retired cells and a modular power system built around it. Both companies showed these products at the event, so what follows keeps a hard line between what was demonstrated on the floor and what each company said about it. Performance figures and cost claims that can’t be independently checked are left out entirely.

Disassembly: putting a robot where hands used to be

Thot’s Dismantlebot is a robot in development that aims to automate battery disassembly using robotic control and AI vision. According to the company, disassembly is one application of a broader push into automating high-difficulty, non-standardized industrial processes — alongside manufacturing and logistics work. The company said it’s targeting real industrial deployment, but the show materials didn’t specify how many units are operating today, or what accuracy and throughput the system currently achieves.

Battery disassembly has largely stayed a manual process. Packs vary by manufacturer and model, and internal layouts aren’t standardized, which is exactly what makes the process hard to automate. Whether a disassembly robot can actually hold up on a factory floor comes down to how reliably it handles that variability — something this show appearance doesn’t settle. What it does confirm is that someone is now building toward it.

Reconfiguration and repurposing: rebuilding a pack for a different job

Barkroad’s booth featured a lithium-ion battery pack reconfigured from retired batteries pulled from Hyundai’s E-GMP EV platform, plus a modular power system that combines multiple packs. The company said the product could serve small fishing boats, agricultural transport equipment, food trucks, and camper vans. Whether any of these have actually been deployed, and how many units are running, isn’t verifiable from what was shown at the booth.

It’s worth running this repurposing pitch through the three-question framework ARC Current laid out in Why Retired EV Batteries End Up in ESS. First: does the application need EV-level instantaneous power? Small fishing boats, transport equipment, and food trucks generally don’t — gradual charge-discharge should be enough. Second: is it a fixed setting where condition can be monitored continuously? This is where these uses diverge from ESS. Camper vans and small boats are mobile and exposed to outdoor and vibration conditions that a stationary installation doesn’t face, making continuous cell-variance monitoring through a BMS harder to sustain. Third: can the pack be reused at the module level without further teardown? This is the question Barkroad’s pitch leans on hardest — reconfiguring E-GMP retired cells into a pack, rather than breaking them down further for size, is what a module-level answer to that question looks like.

Answering one of the three questions well doesn’t make the other two go away. Extending into mobile, outdoor applications still leaves the second question open — whether cell condition can be adequately managed outside a fixed setting. Nothing shown at the booth answers that.

Reading disassembly and reconfiguration as one process

Placed side by side, the two products target two different points in the same pipeline — disassembly and reconfiguration — each with a piece of hardware attached. Much of the public conversation around this industry so far has centered on diagnostic technology for judging whether a battery qualifies for reuse. Standardizing or automating the physically hands-on steps — tearing a pack apart, rebuilding it into another form — has gotten comparatively little attention. These two products look like early attempts to fill that gap.

Based only on what was shown at the event, though, there’s little basis yet for judging how far either gets toward mass production or commercial deployment. What to watch next: how much throughput the disassembly robot can actually deliver, and how well the reconfigured pack holds up outside a fixed, monitored setting.
