Peb yuav tsum paub tias cov ntaub ntub dej graphite yuav tsum tau qhuav ua ntej siv, thiab hais tias cov xov ntawm sab hauv ntawm lub qhov electrode tsis khov. Peb siv cua compressed los ntxuav qhov saum npoo ntawm seem graphite electrode thiab cov xov sab hauv ntawm lub qhov. Yuav tsum tsis muaj roj lossis dej haus; tsis txhob siv cov xov xov hlau lossis hlau txhuam cov ntaub npuag.
Nws yog ib qho tseem ceeb kom ua tib zoo ntsia hlau txuas mus rau hauv lub qhov hluav taws xob ntawm qhov hluav taws xob graphite electrode, thiab ntsia hlau lub ntsej muag electrode (graphite pluaj pom zoo) mus rau hauv qhov electrode ntawm lwm qhov kawg ntawm qhov hluav taws xob tsis txaus.
