Electrode materials for lithium secondary batteries prepared by sol–gel methods

All‐Solid‐State Lithium‐Ion Microbatteries: A Review of Various Three‐Dimensional Concepts

“…Since many thin fi lm battery materials are metal oxides and sol-gel is a common method to prepare such oxides, sol-gel techniques are often applied to form various lithium-ion battery electrode materials, [ 182 ] such as lithium cobalt oxides, [ 140 , 183-185 ] lithium nickel oxides, [ 186 ] lithium manganese oxides, [ 183 ] various vanadium oxides, [ 187 , 188 ] tin oxide [ 185 ] and titanium oxides. [ 140 ] It is, on the one hand, remarkable that sol-gel is a relatively mature technique for the deposition of electrode materials but, on the other hand, that a relatively low number of publications are describing the results for complete battery stacks produced by this method.…”

LiNi0.5Mn1.5O4 Spinel and Its Derivatives as Cathodes for Li-Ion Batteries

“…It is common that after precursors are obtained by wet method, less energy or lower reaction temperature are needed to turn the precursors into final products. Wet chemical methods include coprecipitation method [57][58][59][60], polymerpyrolysis method [61,62], ultrasonic-assisted co-precipitation (UACP) method [63,64], solgel method [65][66][67], radiated polymer gel method [68], sucrose-aided combustion method [69], spray-drying method [70], emulsion drying method [71], composite carbonate process [72], molten salt method [73,74], mechanochemical process [75], poly (methyl methacrylate) (PMMA)-assisted method [76] ultrasonic spray pyrolysis [77], polymer-assisted synthesis [78], combinational annealing method [79], pulsed laser deposition [80], electrophoretic deposition [81], spin-coating deposition [82], carbon combustion synthesis [83], soft combustion reaction method [84], pulsed laser deposition [85], spray drying and postannealing [86], rheological method [87], polymer-mediated growth [88], self-reaction method [89], internal combustion type spray pyrolysis [90,91], a chloride-ammonia coprecipitation method [92], a novel carbon exo-templating method [93], flame type spray pyrolysis [94], self-combustion reaction (SCR) …”

Synthesis and electrochemical properties of monoclinic Li3V2(PO4)3/C composite cathode material prepared from a sucrose-containing precursor

“…The lithiated transition metal phosphates based on either the olivine or Nasicon structures, such as LiMPO 4 [M = Mn, Fe, Co] [1][2][3][4][5][6][7][8][9][10][11][12], Li 3 V 2 (PO 4 ) 3 [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], and LiVOPO 4 [32,33], appear to hold particular promise. In comparison with lithiated transition metal oxides, they display high redox potentials, good Li + transport, remarkable electrochemical and thermal stability, and comparable energy density [28]; however, their low electronic conductivity prevents full use of the total capacity even at slow rates, presenting a major drawback to practical implementation of these materials.…”
