Performance and design considerations for lithium excess layered oxide positive electrode materials for lithium ion batteries

“…The Ni-Mn-Co systems and its transition metal (TM) derivatives including Mn, 6,[73][74][75][76][77] Ni-Mn, 5, Mn-Cr, [114][115][116][117][118][119][120][121][122][123][124] Mn-Fe, [125][126][127][128][129][130][131][132][133][134][135] and Mn-Co [136][137][138][139][140] are predominantly studied due to adoptability from the classical layered oxides already established (corresponding colored open circles in Fig. 1).…”

A Cobalt‐Free Li(Li0.17Ni0.17Fe0.17Mn0.49)O2 Cathode with More Oxygen‐Involving Charge Compensation for Lithium‐Ion Batteries

“…Fe-substituted Li-rich materials [26][27][28][29][30][31][32] have attracted great interesti nr ecent years. [38][39][40][41][42] Therefore, ac lear pictureo ft he redox mechanism of TM or Oo ft he Fe-substituted Li-rich system is necessary to understand whether the behavior of Fe is like that of Co, in which Oi ons are oxidized, and the functionofFes ubstitution. [34,35] In Fe-substitutedL i-rich materials, like other Li-rich materials, anionic reversible redox reactionO 2À /O 2 2À was detected, [36,37] but whether Fe 3 + participates in the redox reaction or not during charging/discharging remains unsure.…”
