Li-electrode tsa graphite ke ntho e ka sehloohong ea ho futhumatsa e sebelisoang ka sebōping sa motlakase sa arc, mokhoa oa ho etsa tšepe moo masela a likoloi kapa lisebelisoa tsa khale a qhibilihang ho hlahisa tšepe e ncha.
Lisebelisoa tsa motlakase tsa arc li theko e tlaase ho haha ho feta libōpi tsa khale tsa ho phatloha, tse etsang tšepe ka tšepe ea tšepe 'me li besoa ke mashala a coking.Empa litšenyehelo tsa ho etsa litšepe li holimo kaha li sebelisa makumane a tšepe 'me li tsamaisoa ke motlakase.
Li-electrode ke karolo ea sekoahelo sa sebōpi 'me li bokelloa ka litšiea.Joale motlakase o feta ka har'a li-electrode, 'me o etsa sekhahla sa mocheso o matla o qhibilihisang litšepe.Li-electrode li fapana haholo ka boholo empa li ka ba bolelele ba limithara tse 0.75 (maoto a 2 le halofo) le bolelele ba limithara tse 2,8.E kholo ka ho fetisisa e boima ba lithane tse fetang tse peli tsa metric.
Ho nka lik'hilograma tse 3 (6.6 lb) tsa li-electrode tsa graphite ho hlahisa tonne e le 'ngoe ea tšepe.
