Effects of Ca doping on the electrochemical properties of LiNi0.8Co0.2O2 cathode material

Rheological phase reaction synthesis and electrochemical performance of Li3V2(PO4)3/carbon cathode for lithium ion batteries

“…The spectra clearly show that the charge-transfer resistance of LVP/C electrode decreased after 1 and 10 cycles. Low resistance is preferred for hopping of lithium ions from one site to another [25] and thus explains the good cycling stability of LVP/C electrode to some extent.…”

Insight into Lithium-rich Layered Cathode Materials Li[Li0.1Ni0.45Mn0.45]O2 in situ Coated with Graphene-like Carbon

“…It indicates that the LPAN coating promotes the formation of big particles through the adhering of graphene-like carbon. This morphology is benefit to the improvement of electrochemical properties since cathode materials with big particles size tend to have high cycle stability [35]. Meanwhile, it is observed in Fig.…”

Adipic Acid Assisted Sol-Gel Synthesis of Li1+x(Mn0.4Ni0.4Fe0.2)1-xO2(0 > x > 0.3) as Cathode Materials for Lithium Ion Batteries

“…As seen from Figure 5(a), there is an appearance of one anodic peak around at 4.2 V during charging process and corresponding reduction peak is observed at 3.6 V on discharge corresponding to the oxidation of Ni 2+ to Ni 4+ and the subsequent reduction of Ni 4+ in the solid solution. 27 It is noted from CV curve that there is no cathodic peak observed around ~3 V, indicating Mn…”
