“…Improving the efficiency of energy recovery processes in relevant applications, such as the regenerative braking in vehicles, elevators and cranes, requires energy storage devices that enable faster charging and discharging compared to existing lithium-ion batteries, which are the highest energy density batteries currently available on the market [1]. Capacitors are also able to charge and discharge much faster than existing batteries, performing hundreds of thousands of charge/discharge cycles without significant loss of capacity.…”

Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electrodes. In particular, we have obtained nanostructured electrodes in Pb and PbO2 through electrosynthesis in a template consisting of a nanoporous polycarbonate membrane. These electrodes are characterized by a wider active surface area, which allows for a better use of the active material, and for a consequent increased specific energy compared to traditional batteries. In this research, the performance of lead-acid batteries with nanostructured electrodes was studied at 10 C at temperatures of 25, −20 and 40 °C in order to evaluate the efficiency and the effect of temperature on electrode morphology. The batteries were assembled using both nanostructured electrodes and an AGM-type separator used in commercial batteries.

“…[3][4][5] Moreover, the nanotechnology age extends the application potentialities of this type of material since the extremely small size particles of the oxide counterpart can be maintained disperse in a conducting polymeric phase, having this way a considerable influence in the electrochemical behaviour of the resulting composite. 3,[5][6][7] In this context, the present work introduces the preparation and characterisation of a new Li 0?33 La 0?56 TiO 3 -polyaniline (PANI) nanocomposite in which the good ionic transport of Li z ions of the oxide nanoparticles is satisfactorily combined with the electronic conductivity of conducting PANI, both at room temperature.…”

A new electrode material based on the Li 0?33 La 0?56 TiO 3 -polyaniline nanocomposite is reported. This material is prepared by in situ polymerisation of aniline in the presence of Li 0?33 La 0?56 TiO 3 nanoparticles. The nanocomposite and its precursors are characterised by X-ray diffraction, thermogravimetry, Fourier transform infrared, TEM, SEM, electrical conductivities and electrochemical measurements. The structural and electrochemistry study reveals the existence of relatively strong interactions between the conducting polymer and the oxide particles to assure good synergy in the transport process. The dc and ac electrical conductivities and diffusion coefficient measurements at room temperature indicate that the conductivity values are several orders of magnitude higher in the composite than in the oxide alone. This behaviour determines better reversibility for Li insertion in charge-discharge cycles compared to the pristine oxide and polymer when it is used as electrode of lithium batteries.

With the anticipated increase in renewable wind and solar energy, efficient storage of electrical energy for balancing energy generation and demand on various time scales is becoming increasingly important. This review summarises the fundamentals of electrical energy storage in capacitors and batteries, discusses the similarities and differences of the two classes of devices and addresses the potential impact of the current research. A number of new materials and device structures that are anticipated to play roles in new devices are reviewed in greater detail. Topics covered are carbon nanotubes (CNTs), graphene, nanostructured transition metal oxides, silicon-based devices, ionic liquids (ILs), ion-conductive polymers and asymmetric supercapacitors.
