“…Obviously, extra energy is consumed to create the viable charging environment. To avoid the range reduction and safety problems during discharge, the active thermal management systems are required for batteries to be heated or cooled when BEVs run in extreme temperature conditions [58,59]. The extra energy consumed by active thermal management system further eats the range of BEVs significantly.…”

“…The low-temperature internal storage is an energy storage system that can optimally perform at room temperature (e.g., 25 °C) and some examples of this are lead acid (PbO2), nickel cadmium (NiCd), lithium ion (Li-on), sodium metal-halide, and nickel metal hydride (NiMH) batteries [55]. Using these batteries at extreme cold or hot conditions can negatively affect their charging and discharging performance [56][57][58][59][60]. For high-temperature external storage, its chemical storage system and electrical conversion unit are separated but somehow linked during charging or discharging processes in order to allow the electrochemical reaction exchanges to happen [55].…”

Abstract:The telecommunication sector plays a significant role in shaping the global economy and the way people share information and knowledge. At present, the telecommunication sector is liable for its energy consumption and the amount of emissions it emits in the environment. In the context of off-grid telecommunication applications, offgrid base stations (BSs) are commonly used due to their ability to provide radio coverage over a wide geographic area. However, in the past, the off-grid BSs usually relied on emission-intensive power supply solutions such as diesel generators. In this review paper, various types of solutions (including, in particular, the sustainable solutions) for powering BSs are discussed. The key aspects in designing an ideal power supply solution are reviewed, and these mainly include the pre-feasibility study and the thermal management of BSs, which comprise heating and cooling of the BS shelter/cabinets and BS electronic equipment and power supply components. The sizing and optimization approaches used to design the BSs' power supply systems as well as the operational and control strategies adopted to manage the power supply systems are also reviewed in this paper.

“…Rechargeable lithium ion batteries (LIBs) have achieved great development during the past decades as power sources for various portable devices such as laptops, smart phones and electric vehicles [1][2][3][4]. However, the specific energy of the commercialized lithium ion batteries will become insufficient for the future electric vehicles due to the low capacity of conventional electrode materials.…”

Guo, Z. (2014). TiO2 coated three-dimensional hierarchically ordered porous sulfur electrode for the lithium/sulfur rechargeable batteries. Energy, 75 597-602.TiO2 coated three-dimensional hierarchically ordered porous sulfur electrode for the lithium/sulfur rechargeable batteries AbstractA three-dimensional (3D) hierarchically ordered mesoporous carbon-sulfur composite slice coated with a thin TiO2 layer has been synthesized by a low-cost process and investigated as a cathode for the lithium-sulfur batteries. The TiO2 coated carbon sulfur composite thin slice works as a binder-free cathode without any current collectors for lithium-sulfur batteries. The hierarchical architecture provides a 3D conductive network for electron transfer, open channels for ion diffusion and strong confinement of soluble polysulfides. Meanwhile, TiO2 (titanium dioxide) coating layer could further effectively prevent the dissolution of polysulfides and also improve the strength of the entire electrode, thereby enhancing the electrochemical performance. As a result, after TiO2 coating, the electrode demonstrates excellent cycling performance, with a discharge capacity of 608 mAh/g at 0.2 C current rate and 500 mAh/g at 1 C current rate after 120 cycles, respectively.
