1. E entsoe ka lisebelisoa tsa boleng bo phahameng ba graphite, li-electrode tsa rona tse nyenyane tsa graphite li hahiloe ho mamella mocheso o feteletseng le ho fana ka motlakase o babatsehang oa motlakase.Sena se tiisa ts'ebetso e tsitsitseng le e sebetsang ea ho qhibilihisa, e hlahisang boleng bo phahameng ba sehlahisoa le ho fokotsa tšebeliso ea matla.
2. Boholo bo bonyenyane ba li-electrode tsena bo lumella hore ho be le taolo e nepahetseng haholoanyane holim'a mokhoa oa ho qhibiliha, ho etsa hore e be e phethahetseng bakeng sa likopo tse hlokang ho nepahala ho phahameng le liphello tse hlophisitsoeng hantle.Hore na o hlahisa li-alloys kapa litšepe tse hloekisitsoeng, li-electrode tsa rona li tla u thusa ho fihlela sephetho se lakatsehang ka nepo e ke keng ea bapisoa.
3. Li-electrode tsa rona tse nyane tsa graphite li loketse mefuta e mengata ea liindasteri, ho kenyelletsa tlhahiso ea tšepe, ts'ebetso ea lik'hemik'hale le ho lahla tšepe.Ho sa tsotelehe boholo ba ts'ebetso ea hau, li-electrode tsa rona li ka hlophisoa ho fihlela litlhoko tsa hau tse ikhethileng.
4. Ha ho etsoa litšepe, li-electrode tsa rona tse nyenyane tsa graphite tse bophara ba tsona li sebelisoa liboping tsa motlakase tsa motlakase, moo li bapalang karolo ea bohlokoa tlhahisong ea tšepe ea boleng bo phahameng.Boholo ba bona bo bonyenyane bo lumella taolo e nepahetseng holim'a mokhoa oa ho qhibiliha, ho netefatsa liphello tse tsitsitseng le ho fokotsa litšila.
5. Ts'ebetsong ea lik'hemik'hale, li-electrode tsa rona li bohlokoa bakeng sa tlhahiso ea calcium carbide le ho ntlafatsa carborundum.Mekhoa ena e hloka taolo e nepahetseng ea mocheso, eo li-electrode tsa rona li fanang ka tsona ka ho nepahala ho fetisisa.
6. Bakeng sa ho lahla tšepe, li-electrode tsa rona tse nyenyane tsa graphite li sebelisoa ho qhibilihisa tšepe e sa tloaelehang le limela tsa Ferrosilicon.The conductivity e phahameng ea graphite e lumella ho qhibiliha ha tšepe hantle, ho fella ka potoloho ea tlhahiso e potlakileng le tlhahiso e phahameng ka kakaretso.
