Preparation of Li1.5Al0.5Ti1.5(PO4)3 solid electrolyte via a sol–gel route using various Al sources

Microwave-assisted reactive sintering and lithium ion conductivity of Li1.3Al0.3Ti1.7(PO4)3 solid electrolyte

“…In the literature, AlPO 4 is very commonly observed, even as traces, in the XRD patterns [24,26,27]. Its action as a resistive layer is well-known and deleterious to ionic conductivity [28]. Here we show that MW-assisted reactive sintering enables producing pure LATP ceramics to be produced, probably because LATP cannot decompose in such a short processing time.…”

Effects of preparation conditions on the ionic conductivity of hydrothermally synthesized Li1+Al Ti2-(PO4)3 solid electrolytes

“…Moreover, actual electrolytes using LATPs have been seen in many earlier examples of lithiumion [17][18][19][20][21][22], Li-air [23,24], and Li-sulfur batteries [25]. For more information, Table 1 summarizes the LATP examples [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]26] prepared by various synthetic methods to obtain various values of room-temperature (RT) ionic conductivity (s) and activation energy (E a ), including the reported ionic conductivities (s b and s g ) and activation energies (E b and E g ) in both phases of bulk and grain boundary. Until now, the highest total s(RT) achievable was proved to be 1.3 Â 10 À3 S cm À1 from the LATP prepared by meltquenching at temperatures over 1400 C [3][4][5], but it is very dangerous to handle due to the extremely high temperature.…”

“…In particular, an LATP particle has grain boundaries that deliver different Li + conduction paths from its bulk phase. More recently, various effective synthesis methods have been tried to prepare LATP with superior electrochemical properties; these methods include meltquenching [3][4][5], sol-gel [6][7][8][9][10][11], mechanical milling [12,13], and co-precipitation [14][15][16] techniques. Moreover, actual electrolytes using LATPs have been seen in many earlier examples of lithiumion [17][18][19][20][21][22], Li-air [23,24], and Li-sulfur batteries [25].…”

Effect of lithium bis(trifluoromethylsulfonyl)imide salt-doped UV-cured glycidyl methacrylate

“…In addition, the lone pairs that were carried by those polar functional groups were believed to contribute to the effective salt solvation [10,11,14]. This behavior attracted much attention from the scientific community to focus on a various type of polymer host containing many polar atoms [15,16]. Methacrylatebased materials become one of the predominant polymer hosts for many works, due to its low processing cost and high chemical and mechanical stability [10,13].…”
