Electronic properties of lithium-ion battery cathodes studied in ion-gated transistor configuration.

ABSTRACT: Electronic and ionic transport governs lithium-ion battery (LIB) operation. The in operando study of electronic transport in lithium-ion transition metal oxide (LMOx) cathodes at different states of charge enables the evaluation of the state of health of LIBs and the optimization of their performance. We report on electronic transport in LIB cathode materials at different states of charge controlled in operando in ion-gated transistor (IGT) configuration. We considered LiNi_0.5Mn_0.3Co_0.2O₂ (NMC532)- and LiMn_1.5Ni_0.5O₄ (LNMO)-based composite materials formulated like in conventional LIB cathodes and operated in the organic electrolyte LP30 (1M LiPF₆ in ethylene carbonate:dimethyl carbonate 1:1 v/v).
