Why are lithium ion batteries so difficult to disassemble?

The disassembly of lithium–ion battery systems from automotive applications is complex and time-consuming due to varying battery designs, flexible components, and safety hazards associated with high voltage and chemicals.

What happens after a battery is disassembled?

After spent batteries are disassembled, the electrodes need to be sorted after being taken out, and then stripped of the active materials from current collector.

What considerations should be taken when disassembling a battery?

The remainder of this paper outlines the considerations that should be taken when disassembling a battery in order to produce test results that are indicative of the true operating state of the battery. Before a battery is disassembled, precautions must be taken to ensure the safety of any handlers during the disassembly process.

Can lithium batteries be recycled?

With the rising EV demand and the need for a closed-loop circular economy, the concept of reusing lithium batteries is becoming popular. The closed-loop manufacturing of LIBs starting with remanufacturing, then repurposing, and finally recycling can benefit the LIB-based energy storage ecosystem.

Can reusing and remanufacturing reduce the cost of lithium-ion batteries?

Recycling coupled with reusing and remanufacturing can bring down the up-front cost of lithium-ion batteries (LIBs). Research suggests that reused and remanufactured batteries will be 30%–70% cheaper by 2025 and account for 26 GWh of energy storage globally.

Can robots disassemble lithium ion batteries?

In the specific context of lithium–ion battery (LIB) pack disassembly, research has demonstrated that human–robot collaboration is the most effective approach. Robots can efficiently cut the battery pack, while technicians can quickly sort battery components and handle connectors or fasteners that might be challenging for robots.
