Additive‐free nanoscale LiCoO2 thin‐films deposited on Si substrates using DC sputtering show exceptional electrochemical performance due to the unique kinetics of the nanoscale thin‐film in aqueous environment. At extremely high scan rates and galvanostatic current densities of up to 100 mV s−1 and 200 C respectively, a capacity retention equivalent to 97 mAh g−1 (4.8 μAh cm−2, 48.3 μAh cm−2 μm−1) is obtained. A significant contribution of non‐diffusion controlled kinetics in a LiCoO2 electrode is shown.

“…In addition, the construction of grid connections is complex and expensive to power IoE devices in hazardous, toxic, or hard‐to‐reach areas . Some devices are not connected to the power grid, such as wireless sensors, health monitors, and wearables . Therefore, a fundamental solution to these challenges is to develop an energy harvesting system that can constantly convert ubiquitous energy into electricity and an energy storage system that can continuously provide electricity to ensure sustainable and maintenance‐free operation.…”

The Internet of Everything (IoE), which aims to realize information exchange and communications for anything with the Internet, has revolutionized our modern world. Serving as the driving force for devices in the IoE network, power supply systems play a fundamental role in the development of the IoE. However, due to the complexity, multifunctionality and wide‐scale deployment of diverse applications, power supply systems face great challenges, including distribution, connection, charging technologies, and management. In this review, some challenges and advances in the development of both power supply systems and their units are presented. In the overall system‐level field, establishing sustainable and maintenance‐free power supply systems through wireless connections, efficient power management and integrated energy harvesting and storage systems is highlighted. Additionally, the main performance metrics of power supply units are discussed, including energy density, service life, and self‐power ability. In addition, some directions of power quality assessment for both the system and unit levels of power supply systems are presented, aiming to provide insight into the future development of high‐performance power supply systems for the IoE.

“…However, conventional coin‐type supercapacitors suffer from many problems, including difficulties in their miniaturization, a high landing area due to an external lead, low volumetric efficiency in the electrode layout, and low surface mounting yield owing to their cylindrical shape. Chip‐type supercapacitors with a ceramic substrate have improved electrical properties and are widely investigated as alternatives to the conventional coin‐type supercapacitors . Generally, alumina‐based ceramics are used as the substrates for chip‐type capacitors because they offer high mechanical strength, which is required to effectively dissipate the mechanical shock generated during surface mounting and device drop test .…”

“…Chip-type supercapacitors with a ceramic substrate have improved electrical properties and are widely investigated as alternatives to the conventional coin-type supercapacitors. [23][24][25][26][27] Generally, alumina-based ceramics are used as the substrates for chiptype capacitors because they offer high mechanical strength, which is required to effectively dissipate the mechanical shock generated during surface mounting and device drop test. [28][29][30] However, nickel (or tungsten), which has a high melting temperature with relatively low electrical conductivity, is preferred for the electrodes because the alumina-based ceramics need to be sintered at high temperatures.…”

A CaO‐B2O3‐SiO2 (CBS) glass/40 wt% Al2O3 composite sintered at 900°C exhibited a dense microstructure with a low porosity of 0.21%. This composite contained Al2O3 and anorthite phases, but pure glass sintered at 900°C has small quantities of wollastonite and diopside phases. This composite was measured to have a high bending strength of 323 MPa and thermal conductivity of 3.75 W/(mK). The thermal conductivity increased when the composite was annealed at 850°C after sintering at 900°C, because of the increase in the amount of the anorthite phase. 0.25 wt% graphene oxide and 0.75 wt% multi‐wall carbon nanotubes were added to the CBS/40 wt% Al2O3 composite to further enhance the thermal conductivity and bending strength. The specimen sintered at 900°C and subsequently annealed at 850°C exhibited a large bending strength of 420 MPa and thermal conductivity of 5.51 W/(mK), indicating that it would be a highly effective substrate for a chip‐type supercapacitor.
