High performances of ultrafine and layered LiCoO2 powders for lithium batteries by a novel sol–gel process

Synthesis of novel high-voltage cathode material LiCoPO4 via rheological phase method

“…Research of cathode materials, such as LiCoO 2 , LiMn 2 O 4 , Li 3 V 2 (PO 4 ) 3 , LiFePO 4 , LiCoPO 4 and others lithium metal (metal = Ni, Co, Mn etc.) mixed oxide compounds, has been the hot spot, recently [1][2][3][4][5][6][7][8][9]. Among these materials, the LiCoPO 4 with an ordered olivine structure has the highest work voltage of 4.8 V [7], far above that of the other materials (3.4-4.1 V), which can increase the energy and power density of LIBs.…”

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

“…Jiao [22] In this work, an attempt has been made to stabilize the LiNi 0.33 Mn 0.33 Co 0.33 O 2 by sol-gel method that employs citric acid as a chelating agent with Cr as a dopant. This soft chemistry technique offers many advantages such as better homogeneity, low calcination temperature, shorter heating time, regular morphology, sub-micron sized particles, less impurities, large surface area, and good control of stoichiometry [23][24][25][26]. The effects of Cr 3+ on the structural, morphological and electrochemical performances are investigated in this paper.…”

Effects of precipitator on the morphological, structural and electrochemical characteristics of Li[Ni1/3Co1/3Mn1/3]O2 prepared via carbonate coprecipitation

“…However, such disadvantages as the high cost, limited capacity and toxicity inhibit its further application in high power and price-sensitive fields, e.g. hybrid electric vehicles (HEV) [3][4][5]. Thus, extensive research has been carried out over the past ten years to find alternative materials with the low cost, long life and high capacity.…”
