“…As can be seen, the discharge/ charge plateau is increasingly shortened with increasing C-rate due to the increase in ohmic resistance and the limitation of lithium diffusion, but it is still apparent at high current densities (such as 2.25 and 5.62 C) compared with that of ATMCNs ( Figure S5, Supporting Information), indicating that less electrode polarization occurs for this hybridized structure. [ 14 ] The rate performance at stepwise C-rates from 0.11 to 5.62 C was shown in Figure 4 c. The average discharge capacities of ATMCNs-GE at 0.11, 0.22, 0.56, 1.12, 2.25, and 5.62 C are 1266.9, 1213.7, 1111.2, 978.0, 793.1, and 509.3 mAh g −1 , respectively. However, they are only 1172.…”

“…Li 4 Ti 5 O 12 has been found to change its structure negligibly during the discharge/charge process, and possesses good lithium ion mobility and a long and stable voltage plateau, together with low cost, environmental friendliness, and enhanced safety. [7][8][9] In addition, as the high equilibrium potential of the Ti 4+ /Ti 3+ redox couple is above the reduction potential of common electrolyte solvents, an SEI film caused by solvent reduction does not form during the charge and discharge process. All of these merits make Li 4 Ti 5 O 12 more competitive as a safe anode material for high power LIBs.…”

. (2014). Rapid synthesis of Li4Ti5O12/graphene composite with superior rate capability by a microwave-assisted hydrothermal method. Nano Energy, Rapid synthesis of Li4Ti5O12/graphene composite with superior rate capability by a microwave-assisted hydrothermal method AbstractLi4Ti5O12 microspheres composed of nanoflakes wrapped in graphene nanosheets have been synthesized by an advanced microwave-hydrothermal (MW-HT) method for the preparation following by an annealing step. Microwave-assisted synthesis processes are appealing, as they can rapidly synthesize materials with a high degree of control of particle size and morphology at low cost. The resultant composite reveals a unique loose structure which could avoid the restacking of graphene sheets and offer rapid lithium ion diffusion paths. Therefore the Li4Ti5O12/graphene electrode has highly desirable properties: a specific capacity approaching the theoretical value, stable cycling, and exceptional rate capability. The composite also can be a good indicator of the remained charge and discharge capacity since it presents a curved charge and discharge line instead of a stable plateau.Keywords rapid, synthesis, li4ti5o12, graphene, composite, superior, rate, capability, hydrothermal, microwave, method, assisted Disciplines Engineering | Physical Sciences and Mathematics Publication DetailsShi, Y., Gao, J., Abruna, H.

[8][9][10] Nevertheless, its potential is still relatively higher, about 1.6 V (versus Li + /Li), thus halving the overall cell voltage and negating the benefits.…”

). Hollow structured Li3VO4 wrapped with graphene nanosheets in situ prepared by one-pot template-free method as an anode for lithium-ion batteries. Nano Letters: a journal dedicated to nanoscience and nanotechnology, 13 (10), 4715-4720. Hollow structured Li3VO4 wrapped with graphene nanosheets in situ prepared by one-pot template-free method as an anode for lithium-ion batteries AbstractTo explore good anode materials of high safety, high reversible capacity, good cycling, and excellent rate capability, a Li3VO4 microbox with wall thickness of 40 nm was prepared by a one-pot and template-free in situ hydrothermal method. In addition, its composite with graphene nanosheets of about six layers of graphene was achieved. Both of them, especially the Li3VO4/graphene nanosheets composite, show superior electrochemical performance to the formerly reported vanadium-based anode materials. The composite shows a reversible capacity of 223 mAh g−1 even at 20C (1C = 400 mAh g−1). After 500 cycles at 10C there is no evident capacity fading. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 2 ABSTRACT: To explore good anode materials of high safety, high
