Over the past decades, the application of new hybrid materials in energy storage systems has seen significant development. The efforts have been made to improve electrochemical performance, cyclic stability, and cell life. To achieve this, attempts have been made to modify existing electrode materials. This was achieved by using nano-scale materials. A reduction of size enabled an obtainment of changes of conductivity, efficient energy storage and/or conversion (better kinetics), emergence of superparamagnetism, and the enhancement of optical properties, resulting in better electrochemical performance. The design of hybrid heterostructures enabled taking full advantage of each component, synergistic effect, and interaction between components, resulting in better cycle stability and conductivity. Nowadays, nanocomposite has ended up one of the foremost prevalent materials with potential applications in batteries, flexible cells, fuel cells, photovoltaic cells, and photocatalysis. The main goal of this review is to highlight a new progress of different hybrid materials, nanocomposites (also polymeric) used in lithium-ion (LIBs) and sodium-ion (NIBs) cells, solar cells, supercapacitors, and fuel cells and their electrochemical performance.

“…[161,162] Other candidates for next-generation, energy-dense, safe, and costefficient batteries for biomedical applications include magnesium batteries, aluminum ion batteries, nickel-zinc batteries, a silicon-based anode for LIBs, proton batteries, and graphite dual ion batteries. [163][164][165][166][167][168][169][170][171][172][173] However, most of these state-of-the-art battery technologies are being developed for large-scale applications, such as for energy grids or electric vehicles, and they do not reliably and efficiently operate at room temperature yet. Further research and efforts will be needed to achieve not only high volumetric energy density and safety, but also miniaturization, cost efficiency, and efficient operation at room temperature for biomedical applications.…”

Implantable and ingestible biomedical electronic devices can be useful tools for detecting physiological and pathophysiological signals, and providing treatments that cannot be done externally. However, one major challenge in the development of these devices is the limited lifetime of their power sources. The state-of-the-art of powering technologies for implantable and ingestible electronics is reviewed here. The structure and power requirements of implantable and ingestible biomedical electronics are described to guide the development of powering technologies. These powering technologies include novel batteries that can be used as both power sources and for energy storage, devices that can harvest energy from the human body, and devices that can receive and operate with energy transferred from exogenous sources. Furthermore, potential sources of mechanical, chemical, and electromagnetic energy present around common target locations of implantable and ingestible electronics are thoroughly analyzed; energy harvesting and transfer methods befitting each energy source are also discussed. Developing power sources that are safe, compact, and have high volumetric energy densities is essential for realizing long-term in-body biomedical electronics and for enabling a new era of personalized healthcare.

Silicon is considered as the desirable anode material for lithium‐ion batteries due to its suitable discharge potential, abundant reserve, and ultra‐high specific capacity. However, poor conductivity and unstable battery performance caused by large volume change during cycling limit the further development of silicon anode. In order to avoid the unstable solid electrolyte interface layer caused by the direct contact between silicon and electrolyte, and to eliminate the structural collapse caused by the volume change during cycling, dimension size reduction, reserved voids, and novel structural framework are usually adopted. Although these methods can effectively improve the defects, a new problem is introduced and cannot be ignored: contact engineering between the coating layer and silicon core. Herein, contact engineering is classified into three categories: face to face (F2F), line to line (L2L), and point to point (P2P) according to the contact modes between the coating and core. There is utilizability of the structure categories of different contact modes and their influence on electrochemical performance. Therefore, in the future research of silicon anode, contact engineering is a non‐negligible aspect in the structural design process. Finally, feasible strategies based on contact engineering have been indicated.
