Improved electrochemical performance of LiCoO2 surface treated with Li4Ti5O12

Recent development and application of Li4Ti5O12 as anode material of lithium ion battery

“…Fig. 2 [75] reported the LiCoO 2 cathode material coated by Li 4 Ti 5 O 12 particles by a simple mechano-thermal process, followed by calcination at 723 K for 10 h in air, and the electrochemical performance studies indicated that a 1.0 wt% Li 4 Ti 5 O 12 coated LiCoO 2 sample treated at this condition exhibits an initial discharge capacity of 171 mAh g À 1 and an excellent cycle stability of about 148 cycles for a cutoff voltage of 80% when cycled between 2.75 and 4.40 V. Ohta et al [76] reported that the discharge capacity of LiCoO 2 was increased by the coating of Li 4 Ti 5 O 12 , and the best performance was observed for a sample with an average thickness of coating layer ca. 5 nm.…”

Electrochemical performance of LiCoO2 cathodes by surface modification using lanthanum aluminum garnet

“…It also resisted the dissolution, by a chemical interaction with the electrolyte solution, of strongly oxidized Co ions from the Li 1−x CoO 2 lattice [8,9], as shown in Table 1. The cell cycling performance of 1.0 wt.% 3LaAlO 3 :Al 2 O 3 -coated LiCoO 2 was compared to the earlier reports of mixed oxide coated LiCoO 2 electrodes in Table 2 [22,[32][33][34][35]. It can be concluded from Table 2 that cycling performance improved after 3LaAlO 3 :Al 2 O 3 was coated on the surface of the LiCoO 2 electrode materials.…”

“…The cell performance of the cathodes was evaluated with coin-type cells of the 2032 configuration. The detailed procedure and operation were described in our previous work [11].…”

Novel Nanocomposite Materials for Advanced Li-Ion Rechargeable Batteries

“…The power densities of the solid-state batteries with the thin Li 4 Ti 5 O 12 layer between the LiCoO 2 cathode and sulfide electrolyte are greatly increased and comparable to those of commercial lithium batteries, which is attributed to the suppression of the lithium-ion transfer. A mechano-thermal method has also been used to prepare Li 4 Ti 5 O 12 -coated LiCoO 2 particles [23]. The Li 4 Ti 5 O 12 coating suppresses the increase of the impedance and the dissolution of Co ions.…”
