Customer ServiceLithium-rich materials (LRMs) are among the most promising cathode materials toward next-generation Li-ion batteries due to their extraordinary specific capacity of over 250 mAh g −1 and high energy density of over 1 000 Wh kg −1. The superior capacity of LRMs originates from the activation process of the key active component Li 2 MnO 3.
As a unique phenomenon of LRMs during the initial charge of over 4.5 V , the activation process provides extra capacity compared to conventional layered cathode materials. Activation of the LRMs involves an oxygen anion redox reaction and Li extraction from the Li 2 MnO 3 phase.
The energetically hindered step of lithium-ion desolvation in the course of ion intercalation into cathode or anode materials for Li-ion batteries is frequently considered to be responsible for the pronounced rate-limitations in the low-temperature and high-power limits of battery operation.
Elemental substitution is also an effective way to adjust the activation of LRMs. In the reported attempts, K, Rb, Cs, Ti, Ru, W, and Re can accelerate the activation, Cr, Fe, Cu, Zn, and F can suppress the activation, while Na, Mg, Ca, Ba, Nb, and Mo can stabilize the oxygen redox but has no significant influence on the activation extent.
Yet, the activation energies drop to 0.2-0.3 eV, when the intercalation of Li-ion proceeds in aqueous solution [7, 39].
Herein, the conformation inversion strategy not only prevents the corrosion of Li anodes caused by cyanide groups of SN, but also helps to regulate Li + flux, thereby facilitating the uniform Li deposition and stable electrolyte/Li anode interface.
