Tšebeliso ea thepa ea li-nanotubes tsa carbon:

Li-nanotube tsa carbon ke mofuta o mocha oa thepa ea moemeli ea tsamaisang motlakase, e ka ntlafatsang ho tsamaisoa ha thepa e sebetsang ea electrode e ntle ho feta li-agent tsa setso tse tsamaisang motlakase. Ke moemeli ea tsamaisang motlakase oa betri ea lithium e ntle ka ho fetisisa. Hona joale li-agent tse tsamaisang motlakase tse sebelisoang haholo bakeng sa libeteri tsa lithium-ion li kenyelletsa haholo-holo carbon black, graphite e tsamaisang motlakase, li-nanotube tsa carbon, li-nanofiber tsa carbon, le graphene. Graphite e ntšo ea carbon le graphite e tsamaisang motlakase ke li-agent tsa setso tse tsamaisang motlakase, tse etsang marang-rang a tsamaisang motlakase a nang le ntlha pakeng tsa thepa e sebetsang; li-nanotube tsa carbon, li-fiber tsa carbon le graphene ke thepa e ncha e tsamaisang motlakase, eo ho eona li-nanotube tsa carbon le li-fiber tsa carbon li leng pakeng tsa thepa e sebetsang. Marang-rang a tsamaisang motlakase a nang le mohala a thehoa, 'me graphene e theha marang-rang a tsamaisang motlakase a nang le bokaholimo pakeng tsa thepa e sebetsang. Mofuta oa khokahano ea mola le mofuta oa khokahano ea bokaholimo li ka haha ​​​​marang-rang a tsamaisang motlakase ka botlalo, e leng se ka ntlafatsang ka ho hlaka ts'ebetso ea thepa ea cathode. Ho tsamaisoa ha thepa, ka hona ho fokotsa palo ea moemeli ea tsamaisang motlakase a ekelitsoeng thepa ea electrode e ntle. Ka kakaretso, palo e eketsoang ea moemeli oa khabone o motšo o tsamaisang motlakase thepa ea cathode hangata e ka ba 3%, ha palo e eketsoang ea baemeli ba bacha ba tsamaisang motlakase joalo ka li-nanotubes tsa khabone le graphene e ka fokotsoa ho fihla ho hoo e ka bang 0.5% ~ 1.0%, e leng se ntlafatsang ho tlatsoa ha thepa e sebetsang ea cathode. Bongata ba matla bo ka thusa ho eketsa bongata ba matla a libeteri tsa lithium-ion. Lipolasitiki tse tsamaisang motlakase: tšebeliso e tšoanang ea thepa ea tsamaisang motlakase ea li-nanotubes tsa khabone, e kopantsoeng le polasetiki ea boenjiniere e ka etsoa ka polasetiki e tsamaisang motlakase e nang le litšobotsi tsa ho tsamaisa motlakase le tsa polasetiki, e sebelisoang haholo ho li-semiconductor le thepa e khahlanong le ho tsitsa.
