The demand for more efficient energy storage devices has become increasingly important in order to face the ongoing energy transition. In this regard, it is equally important to attain the production of these devices with the lowest possible environmental impact. In light of this, the use of waste materials and low‐polluting methods has become a strategic priority. In this study, brewers’ spent grains were utilized as raw material to produce anodic electrodes for lithium‐ion batteries (LIBs). The synthesis process involves only two pyrolysis steps at low temperatures without any chemical treatment, reducing energy investment and waste generation. The result is a porous biocarbon structure—with mixed graphitic and amorphous characteristics—decorated with silica nanoparticles. The presence of silica greatly enhances storage capacity. The obtained biocarbon based electrodes exhibites a capacity of 455 mAh g−1 after 100 cycles, surpassing the standard anode material commonly used in commercial LIBs.

“…The methods for extracting biobased SiO 2 from agricultural wastes are subjected to extensive research. Various sources have been utilized for SiO 2 extraction, such as rice husks ( Zhang et al, 2016 ) ( Kim et al, 2017 ), barley husk ash ( Kalidas et al, 2020 ), bamboo leaves ( Wang et al, 2015 ) ( Lin et al, 2016 ), bamboo charcoal ( Zhang et al, 2018 ), reed plants ( Wang J. et al, 2021 ) ( Liu et al, 2015 ), horsetail ( He et al, 2018 ), sugarcane ( Chen et al, 2021 ), and corn leaves ( Su et al, 2020 ). The SiO 2 content of the biosources mainly depends on the geological origin of the plants.…”

“…The initial step in the leaching method is removing the impurities. Hydrochloric acid (HCl) is identified as the most used acid for the purification process, as reported in studies ( Zhang et al, 2016 ) ( Kalidas et al, 2020 ) ( He et al, 2018 ). The agricultural residues are pulverized using the ball milling method and then mixed with 10% HCl solution for 2–12 h at 70–120°C and are stirred to remove metallic impurities.…”

Lithium-ion batteries (LIBs) are the most preferred energy storage devices today for many high-performance applications. Recently, concerns about global warming and climate change have increased the need and requirements for LIBs used in electric vehicles, and thus more advanced technologies and materials are urgently needed. Among the anode materials under development, silicon (Si) has been considered the most promising anode candidate for the next generation LIBs to replace the widely used graphite. Si cannot be used as such as the electrode of LIB, and thus, carbon is commonly used to realize the applicability of Si in LIBs. Typically, this means forming a-Si/carbon composite (Si/C). One of the main challenges in the industrial development of high-performance LIBs is to exploit low-cost, environmentally benign, sustainable, and renewable chemicals and materials. In this regard, bio-based Si and carbon are favorable to address the challenge assuming that the performance of the LIB anode is not compromised. The present review paper focuses on the development of Si and carbon anodes derived from various types of biogenic sources, particularly from plant-derived biomass resources. An overview of the biomass precursors, process/extraction methods for producing Si and carbon, the critical physicochemical properties influencing the lithium storage in LIBs, and how they affect the electrochemical performance are highlighted. The review paper also discusses the current research challenges and prospects of biomass-derived materials in developing advanced battery materials.

“…Our groups’ collaboration [ 45 , 46 , 47 , 48 ] have demonstrated that pSi derived from magnesiothermic reduction of these plant sources can produce nanostructures for drug delivery. Other research groups [ 49 , 50 , 51 , 52 , 53 , 54 ] have focused on anode material for lithium batteries. Both application areas have generated industrial activity as well as academic research (see Section 4.1 and Section 6 ).…”

Pedagogical tools are needed that link multidisciplinary nanoscience and technology (NST) to multiple state-of-the-art applications, including those requiring new fabrication routes relying on green synthesis. These can both educate and motivate the next generation of entrepreneurial NST scientists to create innovative products whilst protecting the environment and resources. Nanoporous silicon shows promise as such a tool as it can be fabricated from plants and waste materials, but also embodies many key educational concepts and key industrial uses identified for NST. Specific mechanical, thermal, and optical properties become highly tunable through nanoporosity. We also describe exceptional properties for nanostructured silicon like medical biodegradability and efficient light emission that open up new functionality for this semiconductor. Examples of prior lecture courses and potential laboratory projects are provided, based on the author’s experiences in academic chemistry and physics departments in the USA and UK, together with industrial R&D in the medical, food, and consumer-care sectors. Nanoporous silicon-based lessons that engage students in the basics of entrepreneurship can also readily be identified, including idea generation, intellectual property, and clinical translation of nanomaterial products.
