WebHere, we report an inverse case by which the defects generated at the particle surface are continuously pumped into the bulk lattice. We show that, during operation of a rechargeable battery, oxygen vacancies produced at the surfaces of lithium-rich layered cathode particles migrate towards the inside lattice. WebJan 31, 2024 · At higher temperatures (T > 300 °C), the bulk lattice oxygen of the catalyst is involved in the reaction, so a Mars-Van–Krevelen redox mechanism takes place. Under such conditions, the consumed lattice oxygen is regenerated through the adsorption, dissociation, and incorporation of oxygen from the gas phase [23,25,28].
