National Laboratory Astanahttp://nur.nu.edu.kz/handle/123456789/6618The paper proposed the facile and successful preparation of P-doped coffee ground-derived hard carbon using H3PO4 as a dopant material for sodium-ion batteries. The manipulation with 1-3 M of H3PO4, contributed to finding the optimal concentration for the maximum incorporation of phosphorus ions into the carbon framework. The use of 2 M of H3PO4 dopant material for hard carbon as anode for sodium-ion battery delivers promising electrochemical performanceenAttribution-NonCommercial-ShareAlike 3.0 United StatesType of access: EmbargoP-doped coffee ground-derived hard carbonsodium-ion batteriesAbstract
