“…The SEM image analysis using MeasureIT (free edition) obtained particle sizes of LTO-A and LTO-B of 0.521 µm ± 0.180 µm and 0.533 µm ± 0.157 µm, respectively. Meanwhile, the LTO synthesized using LiOH.H 2 O and TiO 2 as starting materials produced agglomerates of particles with a size of around 25-34 µm [25], i.e. around 50 times larger than those produced by this research.…”

Lithium titanate, LTO, was synthesized by solid state reaction with Li 2 CO 3 and TiO 2 powder as precursors. The result was characterized to investigate its crystal structure, phase content, cell parameters, surface morphology, electrical conductivity and its performance as electrode in a lithium ion battery. XRD analysis with Le Bail refinement showed that the prepared materials consisted of 4 phases of Li 4 Ti 5 O 12 , Li 2 TiO 3 , anatase TiO 2 and rutile TiO 2. The surface morphology was still not homogeneous, with an average grain size of 0.533 ± 0.157 µm. When 1% LTO was mixed with graphite and used as anode of an LFP battery, it produced a specific capacity of 130.66 mAhg-1 with Coulombic efficiency of 94.2%. When the composition was 5% of the total anode powder, the specific capacity was 118.74 mAhg-1 and Coulombic efficiency was 92.72%.

“…The Raman spectra of LTO, LTO/GQDs-1, LTO/GQDs-2, LTO/GQDs-3 and LTO/GQDs-4 are shown in figure 2(c), characteristic peaks of LTO and TiO 2 can be observed in Raman spectra. The existentence of characteristic peaks of TiO 2 in LTO indicates that TiO 2 has not completely reacted with LiOH [22]. As for pure LTO, there exists three characteristic peaks located at 237, 420, and 679 cm −1 .…”

Anode materials based on lithium titanate (LTO)/graphene composites are considered as ideal candidates for high-rate lithium-ion batteries (LIBs). Considering the blocking effects of graphene nanosheets in electrodes during ion-transfer processes, construction of LTO/graphene composite structures with enhanced electrical and ionic conductivity via facile and scalable techniques is still challenging for high-rate LIB. In this work, structures of anode materials based on LTO nanoplates embedded with graphene quantum dots (GQDs) are demonstrated for high-rate LIB. The hybrids can be facilely prepared via in situ introduction of GQDs during the process LTO preparation, which enables a uniform dispersion of GQDs within LTO. This method is convenient, rapid, and can be easily scaled-up. The introduction of 0.05 wt.% GQDs can greatly enhance the electrochemical performance of the electrodes. The electrodes with 0.05 wt.% GQDs deliver a specific discharge capacity of 185, 181 and 179 mAh g−1 at 5, 10, and 20 C, respectively. The performance enhancement is suggested to be due to the synergistic interactions between LTO and GQDs. The strategy as well as as-designed structures of LTO/GQDs show potentials for application as high-rate anode materials in LIBs application.

“…Solid electrolyte, SE, is an alternative to overcome the difficulties because of eliminating potential leakage, explosion, and fire risk. Some solid electrolytes for all-solid-state lithium-ion battery (ASSB) have been investigated, including lithium lanthanum titanate, LLTO (Inaguma et al, 2004), lithium titanate (Priyono et al, 2017), lithium lanthanum zirconate (LLZO) (Awaka et al, 2009), lithium phosphorus sulfide (Hayashi et al, 2010), lithium sulfide-phosphorus sulfide (Mizuno et al, 2005), glassy ceramic Li2S-P2S5 (Mizuno et al, 2005) and Li2P3S11 (Hayashi et al, 2010).…”

This research aims to study the Al-Y dopant to Lithium Lanthanum Zirconate (LLZO) to the characteristics and electrical properties of the LLZO as solid electrolyte. The synthesis was conducted through solid state reaction with Al2O3 and Y2O3 as dopant precursors. X-ray diffraction analysis along with Le Bail refinement was done to understand their structure, and phase content inside. The result found that Al and Y doping increased the cubic phase from 49.58% to 84.91%. The Al-Y doped-LLZO (LLZAYO) powder was then treated by a various cold isostatic pressing, CIP of 0, 20, 30, and 40 MPa to understand the effect of cold isostatic pressure to the ionic conductivity and solid electrolyte performance of the material even without heat sintering treatment. The result found that the green pellet of LLZAYO) which was isostatically pressed by 40 MPa at room temperature provides (9.06 ±0.26) x10-6 Scm-1, about 8 times higher than the LLZO without doping, i.e., (1.25 ±0.01) x 10-6 Scm-1. All solid-state battery with the prepare LLZAYO CIP 40 as solid electrolyte shows reversible reaction of Li/Li+ redox accompanied with Al/Al3+ redox. The Al/Al3+ reaction seems to decrease the electronic resistance between LCO-LLZAYO CIP40-Li which causes the full cell performance to decrease. The initial specific charging capacity is 82 mAh/g, and the initial discharge was 83 mAh/g, confirming 101 % of Coulombic efficiency. The discharge capacity drops to 46 mAh/g at second cycle, leading to a decrease in Coulombic efficiency to 56 %.
