Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

Summary: A novel time-optimal multi-point trajectory generator (TMTG) is proposed to improve the motion accuracy and efficiency of robotic manipulators. The TMTG utilizes a piecewise motion profile and a series-parallel analytical strategy to generate optimal trajectories. It eliminates overshoot and undershoot by composing the trajectory of various subtrajectories according to constrained velocity direction. The simulations and experiments demonstrate that TMTG outperforms existing approaches in terms of accuracy and efficiency for multi-joint manipulators, with absolute position errors within 0.007 degrees at the end of motion.
