Electrochemical stability of ZnMn2O4: Understanding Zn-ion rechargeable battery capacity and degradation [PDF]
J. Phys. Chem. C 126, 10957-10967 (2022), 2022 We present a refined Mn-Zn-H$_2$O Pourbaix diagram with the emphasis on parameters relevant for the Zn/MnO$_2$ rechargeable cells. It maps out boundaries of electrochemical stability for MnO$_2$, ZnMn$_2$O$_4$, ZnMn$_3$O$_7$, and MnOOH. The diagram helps to rationalize experimental observation on processes and phases occurring during charge/discharge ...

Mobile Recharger Path Planning and Recharge Scheduling in a Multi-Robot Environment [PDF]
arXiv, 2021 In many multi-robot applications, mobile worker robots are often engaged in performing some tasks repetitively by following pre-computed trajectories. As these robots are battery-powered, they need to get recharged at regular intervals. We envision that in the future, a few mobile recharger robots will be employed to supply charge to the energy ...
