International audienceElectrospinning is attracting close interest as a versatile fabrication method for one dimensional mesostructured organic, inorganic and hybrid nanomaterials of controlled dimensions prepared as randomly oriented or oriented continuous nanofibres that can present internal compositional organisation such as core-sheath, hollow or porous fibre, or even multichannel microtube arrangements. The dimensionality, directionality and compositional flexibility of electrospun nanofibres and mats are increasing being investigated for the targeted development of electrode and electrolyte materials. Specific properties associated with the nano-scale features such high surface to volume and aspect ratios, low density and high pore volume allow performance improvements in energy conversion and storage devices. We review here the application of electrospinning for designing architectured nanofibre materials for dye sensitised solar cells, fuel cells, lithium ion batteries and supercapacitors, with particular emphasis on improved energy and power density imparted by performance improvement to, inter alia, ionic conductivity, cyclability, reversibility, interfacial resistance and electrochemical stability, as well as mechanical strength, of electrospun electrode and electrolyte components
