“…Many macropores maintain their initial shapes and sizes after cycling at such a high current density, which is favourable for obtaining good cycling stability. [27,28,38,[44][45][46]53,[60][61][62] compares the electrochemical performance of the current study with the previously reported works. It can be seen that the electrochemical performance of the HPC anode is superior to most of reported biomass-based carbon materials.…”

“…After 5 min, the brightness of the LED bulb decreases obviously compared with its initial state, while the bulb still can work.

“…The primary coulombic efficiency of HPC anode is about 61.1%. The irreversible capacity loss could be attributed to the formation of SEI, the irreversible lithium-ion intercalation on the new-formed surfaces, and even disordered carbon binder [53][54][55][56]. In the first discharge curve, a plateau is found at about 0.5 V and then disappears in the subsequent discharge curves.…”

Hierarchically Porous Carbon Derived from Biomass Reed Flowers as Highly Stable Li-Ion Battery Anode

et al. 2020

As lithium-ion battery (LIB) anode materials, porous carbons with high specific surface area are highly required because they can well accommodate huge volume expansion/contraction during cycling. In this work, hierarchically porous carbon (HPC) with high specific surface area (~1714.83 m2 g−1) is synthesized from biomass reed flowers. The material presents good cycling stability as an LIB anode, delivering an excellent reversible capacity of 581.2 mAh g−1 after cycling for 100 cycles at a current density of 100 mA g−1, and still remains a reversible capacity of 298.5 mAh g−1 after cycling for 1000 cycles even at 1000 mA g−1. The good electrochemical performance can be ascribed to the high specific surface area of the HPC network, which provides rich and fast paths for electron and ion transfer and provides large contact area and mutual interactions between the electrolyte and active materials. The work proposes a new route for the preparation of low cost carbon-based anodes and may promote the development of other porous carbon materials derived from various biomass carbon sources.

“…This biochar was employed as an anode for an Li-ion battery and showed an impressive discharge capacity of up to 1169 mAh/g. Low porousity biochars have shown far lower performances, as reported by Luna-Lama et al [242], who used spent coffee grounds pyrolyzed at 800 • C and reached a specific capacity of only 360 mAh/g. This trend was confirmed by Zhang et al [243], who reported values of around 600 mAh/g when using a microporous biochar.…”

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

“…SCGs are a source of antioxidant insoluble fiber as well as of essential amino acids and low glycemic sugars, resistant to thermal food processing and digestion [1]. Since 2015, the processing of carbon has been refined and carbon nanosheets were produced starting from SCGs, e.g., [24,30]; as a consequence of this, another new popular issue at the moment is the production of sustainable anodes for lithium-ion batteries, e.g., [31] or [32]. Finally, among these main outcomes, it should be emphasized that the term pellet, the fulcrum of this research, was found in the class of emerging topics.…”

The Role of ICT in Supporting Spent Coffee Grounds Collection and Valorization: A Quantitative Assessment

2019

As never before, there is nowadays the will to consider alternative energy sources from renewable and waste materials so as to preserve planet and society. One of the possible elements suitable for this purpose is every day in our houses: Coffee. Or rather, spent coffee grounds. Indeed, many studies in recent years have addressed its potential exploitation, especially for biodiesel production; recent works also pointed out its possible thermal valorization for industrial processes. In light of this, this paper proposes a new sustainable use of spent coffee grounds, converted into combustible pellets; this source can then be used not only for industrial heaters, but also for public or private buildings. To this end, a feasibility study of a pellet production plant fed by waste collected by vending companies operating in the North of Italy is developed, including the logistic model supported by an Information and Communication Technology (ICT) system to help gather spent coffee grounds from the different companies and collect them into the pellet production facility.
