“…Although the first contributions were reported in early 2000s, showing promising potential for coffee shells and beans-derived carbon, [79][80][81] more recently coffee grounds got back attention as carbon precursor for lithium-and sodium-ion batteries. Improvements in anode performances were reported thanks to the porous honeycomb structure, 82 and both micro-porous 83 and non-porous structures 84 were demonstrated to be effective over 100 cycles.…”

Coffee is among the most drunk beverages in the world and its consumption produces massive amounts of waste. Valorization strategies of coffee wastes include production of carbon materials for electrochemical energy storage devices such as batteries, supercapacitors, and fuel cells.Coffee is one of the most consumed beverages in the world. In the linear model adopted so far, its consumption is associated with huge amounts of waste and spent coffee grounds. These wastes, instead, are very interesting secondary raw materials for several circular economy concepts. Nano-structured porous carbon materials obtained by coffee waste are emerging as active materials for electrochemical energy storage devices like supercapacitors and batteries. The major results achieved in the last decade in this high-value exploitation strategy of coffee wastes are summarized to suggest a new sustainable use of coffee waste in the empowerment of the ongoing transition toward a green, electrified, and happier coffee-drinking society.

“…Electron beam (EB) irradiation has several advantages in the modification of the surface of organic and inorganic materials [10]. (i) The sample can be irradiated at atmospheric pressure regardless of the status of the sample (i.e., surface roughness, phase).…”

“…Surface morphology, oxidation states, optical properties, and electrochemical properties can be modified by EB irradiation [10e12]. For example, Endo et al reported the effects of EB irradiation on the performance of carbon anodes for LIBs and attributed the performance enhancement to the surface structure change in the carbon materials and the degradation of the poly(vinylidene fluoride) (PVDF) binder by the EB irradiation [10]. The degradation of the PVDF binder could affect electrode performance because it is related to the binder content in the bulk material and at the electrolyte interface [13].…”

“…The degradation of the PVDF binder could affect electrode performance because it is related to the binder content in the bulk material and at the electrolyte interface [13]. Turbostratic component formation from the amorphous carbon due to EB irradiation further enhances electrode performance [10]. By contrast, Kim et al found that the electrochemical performance of a V 2 O 5 thin film [11] is enhanced by EB irradiation because of the increased surface area and crystallinity and change in oxidation states.…”

The rotating ring-disk electrode system and ab initio molecular orbital calculations were used to investigate the initial reaction in the reductive decomposition of electrolyte solutions for lithium batteries. It was confirmed that electron transfer is induced by the cathodic polarization of the electrode, forming soluble reduced species which can be reoxidized. This electron transfer is an exothermic reaction with a reaction energy of Ϫ3 eV, from the electrode to the solvent molecules coordinated with lithium ions. This is the initial reaction in the reductive decomposition of electrolyte solutions for lithium batteries, which must be controlled to improve the performance of lithium-ion and lithium secondary batteries.
