Field enhanced Li ion conduction in nanoferroelectric modified polymer electrolyte systems

Lithium Transference Numbers in PEO/LiTFSA Electrolytes Determined by Electrophoretic NMR

“…(ii) Another explanation could be bulk flow effects, for example electroosmotic flow, which was described previously for eNMR of aqueous systems by Hallberg et al and Bielejewski et al 31,33 Field induced orientation.-In the literature of conductivity studies in salt-in-PEO electrolytes, there are only two reports of nonlinear field-dependent effects, however giving no definite answer on the underlying mechanisms. 34,35 Both studies found that at electric field strengths comparable to our present study, the total conductivity of the salt-in-PEO electrolyte is increasing with the electric field strength. Wang and Lei therefore concluded that this may be attributed to an alignment of polymer chains, creating ion pathways with enhanced conduction.…”

Lithium ion transport in solid polymer electrolyte filled with alumina nanoparticles

“…Reference source not found., [8], [10]. The PEO-based film is a flexible solid electrolyte with a low glass transition temperature (T g ), high dielectric constant, and a certain mechanical strength, which can be used for special electronic devices [11], [12].…”

“…[8][9][10] The PEO-based film is a flexible solid electrolyte with a low glass transition temperature (T g ), high dielectric constant, and certain mechanical strength, which can be used for special electronic devices. 11,12 The conductivity in the PEO-based SPE greatly depends on the dynamic properties of the PEO chains. The properties of PEO-based structures depend strongly on the chain length.…”

Polyethylene Oxide-Based Solid-State Composite Polymer Electrolytes for Rechargeable Lithium Batteries

“…55 An electric field has an important influence on the ion conductivity of CPEs with ferroelectric ceramic fillers. 57 Oneorder enhancement of conductivity due to the field is observed at 323 K. The electric field (beyond 15 V cm −1 ) can significantly increase the ion conductivity (by an order of magnitude) in the range of 0−100 V cm −1 , further verifying the field dependence of conductivity. In addition, the particle size and content of ferroelectric ceramic fillers are also important factors on the performance of CPEs.…”
