“…In discharge process, the transition-metal compound will be reduced to transition metal particles and dispersed in Li 2 O matrix. The low electrical conductivity of transition metal compounds together with the volume change and aggregation of transition metal particles limit the performance of these materials [12][13][14][15].…”

Energy storage systems such as Li-ion batteries and supercapacitors are extremely important in today's society, and have been widely used as the energy and power sources for portable electronics, electrical vehicles and hybrid electrical vehicles. A lot of research has focused on improving their performance; however, many crucial challenges need to be addressed to obtain high performance electrode materials for further applications. Recently, the electrostatic spray deposition (ESD) technique has attracted great interest to satisfy the goals. Due to its many advantages, the ESD technique shows promising prospects compared to other conventional deposition techniques. In this paper, our recent research outcomes related to the ESD derived anodes for Li-ion batteries and other applications is summarized and discussed.

“…The 2 nd and 3 rd cycle CV curves show similar profiles at a scan rate of 0.1 mV s −1 . In the first cathodic process, the initial reduction of NiO to Ni is induced by a conversion reaction (NiO + 2Li + 2e − ĺ Ni + Li 2 O) [27]. Two small peaks can be observed at 0.43 and 0.83 V, and preliminary decomposition of the electrolyte forms part of the reversible solid electrolyte interphase (SEI) layer [28].…”

“…[22]). Until 2010, however, the reversible capacities obtained on all kinds of NiO-anodes such as Ni/NiO core shell particles [499], NiO hollow nanospheres [500], NiO microspheres [501], NiO-carbon nanocomposites [502][503][504], NiO porous thin films [505][506][507], NiO/poly(3,4-ethylenedioxythiophene) (PEDOT) composites [508] were confined in the range 250-650 mAh g À1 after 20-50 cycles at current rate 0.1-1C in the voltage range 0.005-3 V. Similar results have been obtained in 2011 with Co-doped NiO Nanoflake arrays showing a capacity of 600 mAh g À1 after 50 discharge/charge cycles at low current density of 100 mA g À1 , and it retains 471 mAh g À1 when the current density is increased to 2 A g À1 [509]. The doping is important since the electrochemical performance is significantly improved with respect to undoped ingle-crystalline NiO nanoflake arrays directly on copper substrates by a modified hydrothermal synthesis and post-annealing [510].…”

Lithium-ion batteries (LiBs) have made considerable progress since the first commercial one by Sony in 1991, which had LiCoO 2 and graphite as active elements of the positive and negative electrodes, respectively. The LiBs are now the primary energy storage devices in the transportation and communications, from portable use in computers, up to electric and hybrid vehicles. More recently, they have also been used as back-up supply units, frequency regulators (load leveling) to integrate on smart grids the electricity produced by windmills and photovoltaic plants (for a recent review, see [1]). These applications require high energy densities, high power, and safety among others. Considerable efforts have been made to propose other electrodes to fulfill these requirements. We have recently reviewed the works and progress concerning the materials for the positive electrode [2][3][4][5][6]. The present work is devoted to the materials for the negative electrode counterpart. It is common to use the terminology anode and cathode for the negative and positive electrodes, respectively, although the electrodes play alternatively the role of anode and cathode during the charge and discharge process. We shall use this terminology in the following for conciseness purposes only.An ideal active anode element should fulfill the following requirements as follows: (1) It must be light and accommodate as much Li as possible to optimize the gravimetric capacity. (2) Its redox potential with respect to Li 0 /Li + must be as small as possible at any Li-concentration. The reason is that this potential is subtracted to the redox potential of the cathode material to give the overall voltage of the cell, and smaller voltage means smaller energy density. (3) It must possess good electronic and ionic conductivities since faster motion of the lithium ions and the electrons also mean higher power density of the cell. (4) It must not be soluble in the solvents of the electrolyte and not react with the lithium salt. (5) It must be safe, i.e. avoid any thermal runaway of the battery, a criterion that is not independent of the previous one, but deserves special attention, especially for use in transportation such as electric vehicles and planes. (6) It must be cheap and environmentally friendly. The different materials proposed as anode elements for Li-ion batteries must be discussed with respect to these different criteria.The graphite is still the most used anode material and is still the reference. The first works giving evidence of the insertion of lithium in graphite date from 1955 [7], confirmed by the synthesis of LiC 6 in 1965 [8]. The synthesis of LiC 6 , however, was not obtained by electrochemical process at that time. Another decade was spent before Besenhard and Eichinger discovered the reversible intercalation of lithium in graphite, proposing this material as an anode in 1976 [9,10]. Increasing the Li content in LiC 6 is possible [8], but no reversible cycling beyond LiC 6 could ever be obtained. The graphite anode can thus be cyc...
