Abstract. High-voltage generation (over 4 V versus Li + /Li) of polyanion-positive electrode materials is usually achieved by Ni 3+ /Ni 2+, Co 3+ /Co 2+, or V 4+ /V 3+ redox couples, all of which, however, encounter cost and toxicity issues. In this short review, our recent efforts to utilize alternative abundant and less toxic Fe 3+ /Fe 2+ and Cr 4+ /Cr 3+ redox couples are
Prelithiation additives may be suitable with industrial battery manufacturing procedures since they may be applied to either the positive or negative electrode . Due to the higher cut-off voltage of LCO materials, the diffusivity of lithium ion decreases, and it seriously hampers the battery capacity.
Such a lithiated phase is preferable as a positive electrode material for assembling complete cells (LIBs) in combination with carbonaceous materials as negative electrodes. In contrast with LiFeF 3, NaFeF 3 is easily prepared as a thermodynamically stable phase because the large Na ions are energetically stabilized at A-sites of the perovskite
