Synthesis and performance of lithium vanadium phosphate as cathode materials for lithium ion batteries by a sol–gel method

Application of quaternized activated carbon derived from Macadamia nutshells for the removal of hexavalent chromium from aqueous solutions

“…The obtained product was calcined for eight hours at 700-900°C in a reducing atmosphere (8 % H 2 in Ar). 40 The electrochemical performances of this material showed an increase in cycling capacity with reasonably good capacity retention of about 95 %. 40 LiNiO 2 was also used as a cathode material for Li-ion batteries.…”

“…39 Li 3 V 2 (PO 4 ) 3 prepared by the sol-gel method involved dissolving LiOH·H 2 O, NH 4 VO 3 , H 3 PO 4 and citric acid in distilled water while stirring continuously and maintaining the pH around 9 by adding NH 3 ·H 2 O. 40 The gel was formed by means of vacuum drying at 120°C for eight hours. The dried gel was heated at 300°C for three hours in air to remove water, NH 3 and CO 2 completely.…”

A review of using spray pyrolysis through sol-gel materials in the synthesis of cathode materials for lithium-ion batteries

“…40 The electrochemical performances of this material showed an increase in cycling capacity with reasonably good capacity retention of about 95 %. 40 LiNiO 2 was also used as a cathode material for Li-ion batteries. The cost of LiNiO 2 was relatively lower than the cost of LiCoO 2 and had a higher reversible capacity.…”

The Electrochemical Performance of Li3V2(PO4)3/Graphene Nano-powder Composites as Cathode Material for Li-ion Batteries

“…The three reduction peaks was also observed at 3.9, 3.6 and 3.5 V corresponding to the reinsertion of the two Li + ions, associated with V 4+ /V 3+ redox couple [31,32]. The capacity of LVP/graphene electrode was calculated based on active material including carbon content.…”
