“…In Li ion battery, to induce a defect energy level in carbon-based substrates can increase the conductivity of substrate and enhance Li adsorption and diffusion [31][32][33] . Meanwhile, to induce defect energy level in active materials may speed up Li ion transport and stabilize some lithiated compounds, and so on [34,35] . Recently, Yan et al has demonstrated that the failure mechanism of layered LiNi 1/3 Mn 1/3 Co 1/3 O 2 by using advanced transmission electron microscopy, lies at crack incubation in the interphase of active materials.…”

“…Hard carbon has a “house of cards” structure containing few approximately parallel graphene sheets stacked together and amorphous region, which has attracted tremendous attention as anodes for both LIBs and PIBs . Besides, these materials have many active sites such as edges, defects, nanopores, which are in favor of the insertion, adsorption and transmission for alkali metal ions . Han and co‐workers reported that hard carbon/graphene composites display a reversible capacity of 480 mA h g −1 at 20 mA g −1 and a stability over long‐term cycling (82% of initial specific capacity after 500 cycles) for LIBs .…”

The low capacity and unsatisfactory rate capability of hard carbon still restricts its practical application for Li/K‐ion batteries. Herein, a low‐cost and large‐scale method is developed to fabricate phosphorus‐doped hard carbon (PHC‐700) by crosslinking phosphoric acid and epoxy resin and followed by annealing at 700 °C. H3PO4 acts not only as a crosslinker to solidify epoxy resin for promoting the degree of graphitization and lowering the specific surface area, but also as phosphorus source for forming PC and PO bonds, thus providing more active sites for Li/K storage. As a result, the PHC‐700 electrode delivers a highly reversible capacity of 1294.8 mA h g−1 at 0.1 A g−1 and a capacity of 214 mA h g−1 after 10 000 cycles at 10 A g−1. As for potassium‐ion batteries, PHC‐700 exhibits a reversible capacity of 381.9 mA h g−1 at 0.1 A g−1 and a capacity of 260 mA h g−1 after 1000 cycles at 0.2 A g−1. In situ Raman and in situ NMR measurements reveal that the P‐containing bonds can enhance the adsorption to alkali metal ions, and the PC bond can participate in electrochemical redox reaction by forming Lix PCy . Additionally, P‐doped hard carbon shows better structural/interfacial stability for improved long‐term cycling stability.

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.
