Dispersibility of nano-TiO2 on performance of composite polymer electrolytes for Li-ion batteries

Nanocomposite polymer membrane derived from nano TiO2-PMMA and glass fiber nonwoven: high thermal endurance and cycle stability in lithium ion battery applications

“…The excellent C-rate performance of LiCoO 2 /Li cell with NCPE is associated with the improvement of the ionic conductivity and interfacial compatibility of NCPE and electrode. [18][19][20][21][22][23][24][25] This result suggests As shown in Fig.6, in the first 100 cycles, the discharge capacity of three kinds of cells are similar (about 135 mAh/g). But with the cycle number increasing, the cycle stability of the cell with CPE declines and the discharge capacity decreases to 20 10 mAh/g after 500 cycles.…”

“…[14][15][16] Croce et al 17 reports that, for adding ceramic particles into polymer electrolyte, the interfacial resistance can be 60 reduced,which will improve C-rate performance. In our previous work, a highly dispersed nano-TiO 2 @PMMA hybrid [18][19][20][21] was successfully prepared by in-situ synthesis of nano-TiO 2 grafted with PMMA. The nano-TiO 2 hybrid was blend with PVDF-HFP solution in DMF solution and then casted on Celgard@2300 to prepare gel composite polymer electrolyte membrane.…”

Flexible, high-voltage and free-standing composite polymer electrolyte membrane based on triethylene glycol diacetate-2-propenoic acid butyl ester copolymer for lithium-ion batteries

“…However, their poor mechanical properties still limit their applications [8][9][10][11]. To address the problems, ceramic fillers such as SiO 2 [12][13][14], Al 2 O 3 [15,16], TiO 2 [17,18] have been incorporated into polymer matrices to develop a new family of composite polymer electrolytes (CPE). It has been noticeable that the addition of ceramic fillers can offer improved ionic conductivity, safety, and in particular, electrolyte/ electrode compatibility [19][20][21].…”

Modified TiO2-SiO2 ceramic filler for a composite gel polymer electrolytes working with LiMn2O4

“…Generally speaking, a CPE used as a device component must be capable of maintaining its rated performance for a sufficiently long time, as appropriate to the particular application [9,10].…”
