Composite films of nanobeam V 2 O 5 and poly-3,4-ethylenedioxythiophene (PEDOT) were grown using an electrochemical polymerization method. PEDOT in the composite film connects the isolated V 2 O 5 nanobeams and gives rise to a conductive network, improved Li-ion accessibility and transport pathways in the electrode. The nanobeam-V 2 O 5 /PEDOT composite film cathodes have high capacities, excellent rate capabilities and cycling stabilities at various C rates: their specific capacities were 262 mAh g À1 at 0.1 C, 239 mAh g À1 at 1 C, 186 mAh g À1 at 10 C, and 141 mAh g À1 at 100 C. After testing the battery for more than 150 battery cycles at a rate of 10 C, the degradation rate was found to be approximately 9 %. The diffusion coefficient of the nanobeam-V 2 O 5 crystalline electrode was calculated to be approximately 4.6 10 À8 ; and those of a-, e-, and d-Li x V 2 O 5 crystalline phases, were estimated to be in the range of (2.1-9.8) 10À10 . Under the conditions of PEDOT coating and networking in the composite film, the diffusion coefficients of each phase of Li x V 2 O 5 that reversibly formed during the discharging and charging processes were able to be estimated.

The scalp nerve block decreased the early post-operative pain after paediatric nevus excision, but it did not decrease the incidence of EA with sevoflurane anaesthesia.
