“…The fundamental challenges, including huge volume deformation of electrode, low electrical conductivity, and dissolution/diffusion of electrochemical intermediates, as well as dendrite propagation on metallic Li anode, plague advanced Li batteries with severe electrode pulverization, poor electron conduction, active materials loss and unstable electrolyte/electrode interface, which lead to poor Coulombic efficiency and rapid capacity decay, and therefore limit their practical realization. Nano‐structured carbonaceous materials reveal significantly potentials to mitigate the above problems in a Li battery owing to their unique structural merits in nano spatial confinement, long/short‐range conductivity, as well as surface/interfacial property …”

Biomass materials are of great interest in high‐energy rechargeable batteries due to their appealing merits of sustainability, environmental benefits, and more importantly, structural/compositional versatilities, abundant functional groups and many other unique physicochemical properties. In this perspective, we provide both overview and prospect on the contributions of biomass‐derived ecomaterials to battery component engineering including binders, separators, polymer electrolytes, electrode hosts, and functional interlayers, and so forth toward high‐stable lithium–ion batteries, lithium–sulfur batteries, lithium–oxygen batteries, and solid state lithium metal batteries. Furthermore, based on the multifunctionalities of bio‐based materials, the design protocols for battery components with desired properties are highlighted. This perspective affords fresh inspiration on the rational designs of biomass‐based materials for advanced lithium‐based batteries, as well as the sustainable development of advanced energy storage devices.

Main observation and conclusion With the increasing demand of sustainable and eco‐friendly resources, it is very attractive to use waste leaves for activated carbon (AC) preparation that can be used in supercapacitors. Considering the practically collected leaves are commonly in mixed nature, and extra efforts are needed to sort these mixtures, we here report the first preparation of AC using mixed leaves from different plants, including Platanus acerifolia (PA), Firmiana platanifolia (FP) and Pistia stratiotes (PS), and compared the results with single leaves‐derived AC materials. These leave‐derived AC samples were characterized with FESEM, EDS, FTIR and Raman spectroscopy, and electrochemical tests. The AC derived from mixed leaves (PA3FP1PS2AC) showed a good specific capacitance of 246 F·g−1 at 1 A·g−1 in aqueous 3 mol·L–1 KOH. This sample further showed the largest specific capacitance of 201 F·g−1 at 5 A·g−1, as compared with the non‐mixed AC samples, and a good stability of 100.0% capacitance retention over 1000 cycles. Utilizing mixed leaves for AC preparation is not only demonstrated to be a promising approach of low cost and high‐performance AC production for supercapacitor applications, but may also help environmental protection by reducing the invasive species problem.

How to prepare porous carbons with appropriate structure for supercapacitors is a big challenge. In general, activation is the simplest way to obtain porous carbons. Porous bamboo-like CNTs were fabricated by simple activating sulfonated polymer nanotubes with steam at 800 C. Compared with the unactivated one, activated carbon nanotubes (ACNTs) have good tubular structure, larger specific surface area and rich porosity thanks to the protection of steam during the activation. The ACNTs electrode for supercapacitors displays a specific capacity of 276 F g −1 at 1 A g −1. When assembling ACNTs into a symmetrical supercapacitor, the specific capacity of the device can retain 98% after 10 000 cycles, and this result shows the great application prospect of ACNTs for supercapacitors.
