“…Various biomass precursors, such as rice husk [121], peanut shell [122], lignite [123,124], have been used to produce activated carbon materials by microwave activation for supercapacitor application. For example, He et al reported a high-performance mesoporous carbon derived from rice husk by microwave-assisted activation method, which demonstrated a high specific surface area of 1634 m 2 g −1 and a maximum capacitance of 245 F g −1 [122].…”

Electrochemical energy storage devices, such as supercapacitors and batteries, have been proven to be the most effective energy conversion and storage technologies for practical application. However, further development of these energy storage devices is hindered by their poor electrode performance. Carbon materials used in supercapacitors and batteries are often derived from nonrenewable resources under harsh environments. Naturally abundant biomass is a green, alternative carbon source with many desired properties. This review article presents state of the art of renewable carbon materials derived from natural biomasses with an emphasis on their applications in supercapacitors and lithium-sulfur batteries. IMPACT STATEMENTThis review paper provides a comprehensive understanding for obtaining renewable carbons from natural biomass precursors via various activation methods for electrochemical energy storage application, especially for supercapacitor and lithium sulfur battery.

The aim of this work is to give a procedure to compute an ISS Lyapunov function (ISS ‐ input‐to‐state stability) for a large‐scale networked control system (NCS) in which sensors, controllers and actuators are connected via multiple communication networks that operate asynchronously, [1]. The main idea is that the NCS is modeled as an interconnection of controlled subsystems and (hybrid) error systems, for which local ISS Lyapunov functions can be derived from the underlying medium access control (MAC) protocol systematically. The application of a small‐gain result leads to the construction of an ISS Lyapunov function for the whole NCS. In particularly, maximally allowable transfer intervals (MATIs) and maximally allowable delays (MADs) for each communication network can be computed that are directly related to the ISS gains and convergence rates. In this respect, tradeoffs between the quality‐of‐control (QoC) of the whole NCS and the quality‐of‐service (QoS) of the communication networks become explicit. (© 2016 Wiley‐VCH Verlag GmbH & Co.

“…The mesopore percentage of the CCFs0 is only 14%. The mesopre percentage of CCFs increases with the increase in the ZnCl 2 /cotton mass ratio from 1 to 3, indicating that the porosity created by ZnCl 2 activation is due to the space activated and left by ZnCl 2 after washing [15]. The average pore size increases from 1.97 to 2.65 nm, and the yield decrease from 26.2 % to 23.1% with increase of the ZnCl 2 /cotton mass ratio from 1 to 3 ( Table 1).…”

Abstract.Cotton, an inexpensive natural product, was used as a precursor for fabrication of high specific capacitance porous carbon fibers for spercapacitors. Porous carbon fibers with the hollow structure, high surface area of 1620 m 2 g -1 and high content of C=O functional group are prepared by one-step carbonization and activation using ZnCl 2 as activation agent. The maximum specific capacitance of porous carbon fibers activated at a ZnCl 2 /cotton mass ratio of 2:1 is measured to be 426.7 F g -1 at a current density 0.6 A g -1 . The tubular structure, high surface area, and high content of oxygen functional groups are responsible for the excellent electrochemical performance.
