Strain accommodation and potential hysteresis of LiFePO4 cathodes during lithium ion insertion/extraction

Interdispersed Amorphous MnOx–Carbon Nanocomposites with Superior Electrochemical Performance as Lithium‐Storage Material

“…In addition to kinetics, GITT can also yield thermodynamic properties such as the equilibrium potential and potential hysteresis. [27] The overpotential of the amorphous MnO x -C in the first lithiation gradually decreased with lithiation because: 1) the defects and deformation generated from the volume change in initial lithiation decreased the resistance in subsequent lithiation processes; and 2) the electronic conductivity of the converted …”

Freeze-drying synthesis of Li3V2(PO4)3/C cathode material for lithium-ion batteries

“…LiFePO 4 is one of the most promising candidates for cathode materials of LIBs, which shows appealing features such as high theoretical capacity (170 mAh g À1 ), low cost, high safety and environmental benignity [5][6][7]. In recent years, another lithium metal phosphate, monoclinic Li 3 V 2 (PO 4 ) 3 is also considered to be one of the most promising cathode materials due to its good ion mobility, high theoretical capacity and relatively high operate voltage [8][9][10][11][12][13][14].…”

Water‐Soluble Conductive Composite Binder Containing PEDOT:PSS as Conduction Promoting Agent for Si Anode of Lithium‐Ion Batteries

“…The voltage difference between the charge and discharge curve reflects the polarization intensity during the discharge/charge process. [52][53][54] The different polarizations during the discharge/charge process are due to different resons. The total polarization of the electrode resulted in the voltage hysteresis.…”

“…The total polarization of the electrode resulted in the voltage hysteresis. [52,53] The hysteresis at around 0.4 V, corresponding to the typical discharge plateau of Si as indicated by the blue arrows, was picked up and analyzed ( Figure 5 a-c). The voltage difference as a function of current density is shown in Figure 5 d.…”
