This study presents a novel approach to synthesize N-doped hard carbons via co-hydrothermal treatment of vine shoots and pig manure and subsequent thermal annealing of the resulting hydrochar. This method enhances the development of micro- and ultra-microporosity in the synthesized hard carbons, with nitrogen, and to a lesser extent phosphorus and sulfur, introduced as doping elements. Furthermore, the incorporation of hydrochloric acid during the hydrothermal step promotes biomass hydrolysis, leading to increased mesoporosity and the formation of microsphere clusters. In the realm of electrochemical performance, an investigation into various ester- and ether-based electrolytes has revealed NaPF6 in diglyme as the best formulation, thanks to its thinner and more stable solid electrolyte interface (SEI). Using this electrolyte, the best-performing electrode showed an initial Coulombic efficiency (ICE) of 73 %, with reversible capacities of 239, 180, 86, and 57 mAh g−1 at 0.1, 1, 5, and 10 A g−1, respectively. In addition, the electrode exhibited a remarkable capacity retention of 88 % after 250 cycles as well as a compatible behavior when paired with a NVPF-based cathode. info:eu-repo/grantAgreement/ES/DGA-FEDER/T22-23R info:eu-repo/grantAgreement/ES/MICINN/PID2029-107737RB-I00 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es 7.9 2024 CHEMISTRY, PHYSICAL 43 / 185 = 0.232 2024 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 88 / 461 = 0.191 2024 Q1 T1 ENERGY & FUELS 41 / 182 = 0.225 2024 Q1 T1 ELECTROCHEMISTRY 7 / 44 = 0.159 2024 Q1 T1 1.784 2024 Electrical and Electronic Engineering 2024 Q1 Renewable Energy, Sustainability and the Environment 2024 Q1 Physical and Theoretical Chemistry 2024 Q1 Energy Engineering and Power Technology 2024 Q1 14.9 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Antorán, Daniel Universidad de Zaragoza Darjazi, Hamideh Elia, Giuseppe Antonio Sebastian, Victor Universidad de Zaragoza (orcid)0000-0002-6873-5244 Manyà, Joan J.
