Li 2 O-Al 2 O 3 -TiO 2 -P 2 O 5 (LATP) glass was fabricated by conventional melt quenching route. Glass transition temperature (T g =296°C) and crystallization temperatures (T C1,2 ) were obtained from thermal analysis. LATP glass was converted to glass-ceramic by heat treatment in the range 550-950°C for 6 h. X-ray diffraction analysis revealed LiTi 2 (PO 4 ) 3 as a major phase. Ionic conductivity increased monotonically with concentration, reaching a maximum of~10 −4 S/cm. AlPO 4 phase was detected in samples heat-treated above 850°C. Its presence decreased the conductivity, suggesting LiTi 2 (PO 4 ) 3 phase as main contributor to high ionic conductivity. NMR spectra confirmed the presence of mobile 7 Li ions in the entire sample series and also gave some information on the structure and dynamics of conductivity.

Lithium silicate thin films were successfully deposited by pulsed laser deposition (PLD) technique using an ArF excimer laser. The ionic conductivities, the structures and the stability against CO 2 of the lithium silicate films were examined. The ionic conductivity value at 25°C was 2. IntroductionAll-solid-state thin-film rechargeable lithium batteries are now demanded for micro power devices. The key material for the TFB is amorphous lithium-ion conductor as the electrolyte. In comparison with crystalline electrolyte, amorphous materials have advantages such as good contact with electrode, isotropy of lithium ion conduction and so on. TFBs should be stable for many cycles. Therefore it is important to develop a thin film solid electrolyte which is stable in cycles especially against possible reductions at negative electrode.LVSO (Li 2 O-V 2 O 5 -SiO 2 ) is the amorphous solid state electrolyte which is deposited by PLD 1,2) . The battery fabricated with LVSO (Li 2.2 V 0.54 Si 0.46 O 3.4 ) film shows poor reversibility on CV cycles. This is because of the reduction of vanadium at the interface to the negative electrode.Lithium silicate glasses (Li 2 O-SiO 2 ), which is prepared by removing vanadium from LVSO, are an amorphous solid-state-electrolyte with a wide band gap, which has good charge-discharge reversibility in cycles. Because of its wide gap, lithium silicate thin film is difficult to be deposited by pulsed laser deposition (PLD) technique. By using an ArF excimer laser ( =193 nm), the lithium silicate thin film can be successfully deposited.

“…Fabrication techniques of nano-structured Sn, SnO 2 and carbon/tin composites include autocatalytic deposition [44], ball-milling [41,45,51], chemical reduction [46,50], electrodeposition [47], hydrolysis [48], pyrolysis [49,] sputtering [52], plasma laser deposition (PLD) [53], sol-gel techniques [54], partial reduction [55], precipitation [56], sonochemical methods [57], and vapor deposition [58]. However, these processes often involve several time consuming steps and offer only limited control of the particle size and distribution.…”

In this paper we report results of a novel synthesis method of thin-film composite Sn/C anodes for lithium batteries. Thin layers of graphitic carbon decorated with uniformly distributed Sn nanoparticles were synthesized from a solid organic precursor Sn(IV) tert-butoxide by a one step microwave plasma chemical vapor deposition (MPCVD). The thin-film Sn/C electrodes were electrochemically tested in lithium half cells and produced a reversible capacity of 440 and 297 mAhg -1 at C/25 and 5C discharge rates, respectively. A long term cycling of the Sn/C nanocomposite anodes showed 40% capacity loss after 500 cycles at 1C rate.
