Li diffusion in LiNi0.5Mn0.5O2 thin film electrodes prepared by pulsed laser deposition

Electrochemical performance of LiNi1/3Co1/3Mn1/3O2 thin film electrodes prepared by pulsed laser deposition

“…It is noted that the plot of D Li versus the cell voltage exhibits a minimum around 3.67 V, which coincides with the plateau observed in the voltage profile during chargeedischarge cycling. Similar results were also obtained by Shaju [7], Liao [30] and Xia et al [31]. The values of D Li in LiNi 1/3 Co 1/3 Mn 1/3 O 2 thin film electrode are in the range of 10 À9 e10 À10 cm 2 s À1 .…”

“…The D Li values in this study are in agreement with the results obtained from GITT in LiNi 1/3 Co 1/3 Mn 1/3 O 2 composite electrodes (10 À9 e10 À10 cm 2 s À1 ) [7]. However, the D Li values are higher than those obtained from GITT in 300 Cannealed LiCoO 2 thin films (10 À12 e10 À13 cm 2 s À1 ) [30] and LiNi 0.5 Mn 0.5 O 2 thin films (10 À12 e10 À16 cm 2 s À1 ) [31].…”

Hierarchical Porous LiNi1/3Co1/3Mn1/3O2 Nano-/Micro Spherical Cathode Material: Minimized Cation Mixing and Improved Li+ Mobility for Enhanced Electrochemical Performance

“…Cyclic voltammetry analyses at various scan rates were carried out to investigate the lithium ion apparent diffusion coefficient, which is a key factor for electrochemical performance31. For both PNM-NCM and Bulk-NCM, the anodic peak shifts to higher potential while the cathodic peak shifts to lower potential with increasing scan rate from Figs 7a and S7a†, indicating the diffusion controlled behavior.…”

Electrochemical performance of all-solid-state Li batteries based LiMn0.5Ni0.5O2 cathode and NASICON-type electrolyte

“…As seen in Fig. 7, the potential difference between cathodic and anodic peak in the CV plot is about 0.5 V, larger than that of the well-crystallized LiMn 0.5 Ni 0.5 O 2 thin film soaked by the liquid electrolyte [24,25], also suggesting a sluggish electrode kinetics of the all-solid-state battery.…”
