Macroporous Li(Ni1/3Co1/3Mn1/3)O2: A High‐Power and High‐Energy Cathode for Rechargeable Lithium Batteries

“…, [9] 153 mA h g -1 at 2 C (360 mA g -1 ), [17] 132 mA h g -1 at 4 C, [20] 115 mA h g -1 at 700 mA g -1 , [37] and 125 mA h g -1 at 750 mA g -1 . [40] The best literature result is 145 mA h g -1 at 12 C and at 30°C reported by the group of Ohzuku for material synthesized using the mixed-hydroxide method. [12] Voltage profiles for charging to 4.6 V and discharging to 2.5 V at increasing rates from 20 to 4000 mA g -1 and at 30°C are shown in Figure 5b.…”

Improvement of the electrochemical performance of LiNi0.33Mn0.33Co0.33O2 cathode material by chromium doping

“…Since LiNi 0.33 Mn 0.33 Co 0.33 O 2 was first proposed by Ohzuku et al [1], it has attracted great interest as a promising cathode material for lithium secondary in terms of operating voltage, high discharge capacity, high rate capability, cycleability, good structure, and thermal stability [2][3][4][5][6]. However, its rate capability and cycling performance at high current density are not satisfactory [7,8]. The origin of these phenomena is mainly related to its low electronic conductivity, transitional metal ions dissolution into the electrolyte and the instability of the surface layer between the active particles and the electrolyte solution [9][10][11][12][13].…”

Rational Construction of a Functionalized V2O5 Nanosphere/MWCNT Layer‐by‐Layer Nanoarchitecture as Cathode for Enhanced Performance of Lithium‐Ion Batteries

“…[9][10][11][12][13] Moreover, cost effectiveness, facility of synthesis, and abundance in natural resource are other important advantages of investigatingV 2 O 5 cathode.Nevertheless, achieving decent electrochemical performances for V 2 O 5 in various aspects, including specifi c capacity, rate capability, and cycle life, has been a challenge which is ascribed to its low ionic diffusivity and inferior electrical conductivity. [ 9,[14][15][16] To address these intrinsic drawbacks, an effective strategy was adopted to decrease the active materials to nanoscale level, such as nanowires, [ 17 ] nanorods, [ 18 ] nanobelts, [ 19 ] and nanospheres, [ 20,21 ] which can shorten the transport lengths both for electrons and Li ions, minimize the effect of the low ionic diffusivity, and better accommodate the strain of Li ions intercalation/deintercalation in active materials.…”
