Interesting article on restoring battery capacity. https://www.sciencedaily.com/releases/2022/01/220104095611.htm If anyone has access to the full report, I'd love to read it. Or at least understand what charge and discharge rates (C rate) they used to get results. Also interest if this research proves what the Nissan Leaf community has known for quite some time. Repeated attempts at rapid acceleration and then regen braking can increase the vehicles SOH, and if this can be applied to other electric vehicles.
Beyond interesting! This study needs independent replication. Highlights for me: ""We found that we can move the detached lithium toward the anode during discharging, and these motions are faster under higher currents," said Liu. "So we added a fast, high-current discharging step right after the battery charges, which moved the isolated lithium far enough to reconnect it with the anode. This reactivates the lithium so it can participate in the life of the battery."" ""It's like a very slow worm that inches its head forward and pulls its tail in to move nanometer by nanometer," Cui said. "In this case, it transports by dissolving away on one end and depositing material to the other end. If we can keep the lithium worm moving, it will eventually touch the anode and reestablish the electrical connection."" Bob Wilson
