Direct fabrication of LiCoO2 thin-films in water–ethanol solutions by electrochemical–hydrothermal method

Water‐Based Paintable LiCoO2Microelectrodes: A High‐Rate Li‐Ion Battery Free of Conductive and Binder Additives

“…At such high charge and discharge rates, the risk of failure of the cell is very high due to the intense current peaks in the first stages of charging, which can lead to irreversible structural damages of LiCoO 2 . Also, this can produce high overcharges leading to several catastrophic events: i) collapse of the layered LiCoO 2 structure, ii) release of oxygen, iii) oxidative decomposition of the electrolyte solvents, and consequently, iv) thermal runaway in the cell. Results of this charge–discharge program are shown in Figure D.…”

Advances in Cathode Nanomaterials for Lithium-Ion Batteries

“…The influence of parameters such as ethanol-water ratio, pressure, temperature, current density and reaction time were evaluated on the R3m layered phase formation and in the electrochemical response of Li batteries. The results show that well-crystalized LiCoO2 with preferred orientation (101) without traces of spinel-like phase and cobalt oxide impurities were achieved and show a capacity of around 120 mAh.g -1 (Azib et al 2015).…”

“…Different methods and synthesis routes such as sol-gel (Balakrishnan et al 2018;and Gao et al 2015), flux-coating (Mizuno et al 2014), one-step electrochemicalhydrothermal (Azib et al 2015), combustion (Rodrigues et al 2001), microwave (Hu et al 2004), hydrothermal (Burukhin et al 2002), thermal decomposition (Mizuno et al 2012) and auto flame (Singh et al 2018), were used to produce the LiCoO2.…”

“…In Azib's approach (Azib et al 2015), thin films of LiCoO2 were synthesized via electrochemical-hydrothermal route using ethanol and water blends as a solvent. The influence of parameters such as ethanol-water ratio, pressure, temperature, current density and reaction time were evaluated on the R3m layered phase formation and in the electrochemical response of Li batteries.…”

Recent progress in hybrid cathode materials for lithium ion batteries

“…4 Cathode materials are one of the most important components of LIBs and play a critical role in determining the performance of LIBs. 5 In the past few years, many cathode materials have been reported, such as LiCoO 2 , [6][7][8][9][10][11][12] LiMn 2 O 4 , [13][14][15] LiMnPO 4 , [16][17][18][19][20] LiTi 2 (PO 4 ) 3 , [21][22][23] LiFePO 4 , [24][25][26][27][28][29][30][31][32][33] Li 3 V 2 (PO 4 ) 3 , [34][35][36][37][38][39][40][41] LiVPO 4 F 42,43 and LiVOPO 4 .
