Ohlelweni lwebhethri lwebhethri lwamanje lwe-Lithium-Ion, isici esinqunyelwe ikakhulukazi ukuthuthuka kukagesi. Ikakhulu, ukuthuthuka okunganele kwento eyanele ye-elektrode kukhawulela ngqo umsebenzi wokuphendula kwe-electrochemical. Kuyadingeka ukwengeza i-ejenti efanelekile yokuqhuba i-ejenti yokuvuselelwa kokwenziwa futhi kwakha inethiwekhi esebenzayo ukuhlinzeka ngesiteshi esisheshayo sezokuThutha i-elektroni futhi kuqinisekiswe ukuthi izinto ezisebenzayo zisetshenziswa ngokuphelele. Ngakho-ke, i-ejenti esebenzayo nayo iyinto ebaluleke kakhulu kwibhethri le-lithium ion lihlobene nezinto ezisebenzayo.

Ukusebenza kwe-ejenti ephethe kuncike ngezinga elikhulu esakhiweni sezinto zokwakha kanye nemikhuba lapho ukuxhumana khona nezinto ezisebenzayo. I-Lithium Ion Battery yebhethri yebhethri yebhethri inezimpawu ezilandelayo:

. Izinhlayiya ezinhle, uchungechunge lwenethiwekhi olugcwele kakhulu, indawo enkulu engaphezulu komhlaba, kanye neyunithi yeyunithi, okuzuzisa ukwakha isakhiwo esisebenzayo se-electrode. Njengommeleli walabo abasebenza ngendabuko abasebenza ngendabuko, i-carbon emnyama njengamanje ingumenzeli osetshenziswa kakhulu osebenza. Okubi ukuthi intengo iphakeme futhi kunzima ukuhlakazeka.

(2)I-graphite: I-Graphite ye-Praphite ibonakala ngosayizi wezinhlayiyana eduze kwaleyo yezinto zokwakha ezinhle nezingalungile, indawo ekhethekile yokulinganisa, kanye nokusebenza okuhle kukagesi. Isebenza njengendawo yenethiwekhi esebenzayo ebhethri, nakwi-electrode engemihle, ayikwazi ukwenza ngcono ukuhambisa, kodwa futhi namandla.

. Okubi ukuthi kunzima ukuhlakazeka.

(4)I-Carbon Nanotubes (CNTs): Ama-CNTs ama-ejenti athuthukile aqhamuke eminyakeni yamuva. Ngokuvamile banesilinganiso esingaba ngu-5mm nobude be-10- 20um. Azikwazi ukwenza kuphela "njengezintambo" kumanethiwekhi ahambisanayo, kepha futhi zinomphumela we-electrode acler we-electrode ukuze uwadlale izici eziphezulu ze-supercapacitors. Ukuvuselelwa kwayo okuhle okushisayo nakho kuyasiza ekushiseni kokushisa ngesikhathi sokushaja kwebhethri nokukhipha, ukunciphisa ukukhiqizwa kwebhethri, ukuthuthukisa ukusebenza kwebhethri okuphezulu kanye nokushisa kwebhethri.

Njengomenzeli oqhutshwayo, ama-CNTs angasetshenziswa ngokuhambisana nezinto ezahlukahlukene ze-elektrode ezinhle ukuthuthukisa amandla, isilinganiso, kanye nomjikelezo wokusebenza kwe-material / ibhethri. Izinsizakusebenza ze-elektrodi ezinhle ezingasetshenziswa zifaka phakathi: I-LILNO2, I-Limn2O4, i-LifePo4, i-Electrode enhle ye-polymer, i-LI3V2 (i-Po4) 3, i-MANnganese onide, nokunye.

Uma kuqhathaniswa namanye ama-ejenti ajwayelekile asebenzayo, ama-carbon nanotubes anezinzuzo eziningi njengama-ejenti amahle futhi angemuhle amabhethri e-lithium ion. I-Carbon Nanotubes inokuphakelayo okuphezulu kukagesi. Ngaphezu kwalokho, ama-CNTs anesilinganiso esikhulu se-Aspect, futhi inani elingezansi lokungezwa lingafinyelela umkhawulo we-percolation ofana nezinye izengezo (ukugcina ibanga lama-elektroni afudumele noma endawo). Njengoba i-carbon nanotubes ingakha inethiwekhi esebenza kahle ye-elektroni yezothutho, inani lokuvuselela elifana nalelo lesengezo esiyindilinga lingatholakala nge-0.2 wt% ye-SWCNTS.

(5)UhloboUhlobo olusha lwe-Plan Carbon Carbon Carbon Carnol enezimo ezimbili ezinobudlova obuhle kakhulu kagesi nobudlova. Isakhiwo sivumela i-graphene sheet ungqimba ubheke izinhlayiya ezibonakalayo ezisebenzayo, futhi zinikeze inani elikhulu lezindawo zokuxhumana ezisebenzayo ze-electrode ezisebenzayo ze-electrode ezisebenzayo, ukuze ama-elekthronikhi angenziwa endaweni enezinhlangothi ezimbili ukuze wakhe inethiwekhi enkulu yendawo yokusebenza. Ngakho-ke kubhekwe njenge-ejenti ekahle yokusebenza njengamanje.

I-carbon emnyama kanye nezinto ezibonakalayo ezisebenzayo zithintana nezimpawu zokuxhumana, futhi zingangena ezinhlwini zezinto ezisebenzayo ukuze zikhuphule ngokugcwele isilinganiso sokusetshenziswa kwezinto ezisebenzayo. I-carbon nanotubes isezingeni eliphakeme lokuxhumana, futhi lingagxilwa phakathi kwezinto ezisebenzayo zokwakha isakhiwo senethiwekhi, esingenakukhulisa i-ejenti elisezingeni eliphakeme, elingaxhunyaniswa yi-point-avel yenethiwekhi, kodwa kunzima ukumboza ngokuphelele impahla esebenzayo. Noma ngabe inani le-graphene enenyeli liyanda ngokuqhubekayo, kunzima ukusebenzisa ngokuphelele izinto ezisebenzayo, futhi lisebenzise i-lions linye futhi lilimaze ukusebenza nge-elektrode. Ngakho-ke, lezi zinto ezintathu zinenkambiso enhle yokuhambisana. Ukuxuba i-carbon emnyama noma ye-carbon nanotubes ene-grapheen ukwakha inethiwekhi ephelele yokuqhutshwa kungathuthukisa ukusebenza kwe-electrode.

Ngaphezu kwalokho, ngokombono we-graphene, ukusebenza kwe-graphene kuyavela ezindleleni ezihlukile zokulungiselela, ngokwezinga lokuncishiswa, ubukhulu beshidi kanye nesilinganiso se-carbon Black, i-electrode yonke ithinta izinzwa ze-agents ephathekayo. Phakathi kwazo, selokhu umsebenzi we-ejenti ophethe ukwakha inethiwekhi esebenzayo yezokuhamba ze-elektroni, uma i-ejenti ye-ejenti uqobo ayihlakazwa kahle, kunzima ukwakha inethiwekhi esebenzayo yokusebenza. Uma kuqhathaniswa ne-ejenti yendabuko ye-carbon emnyama yokuqhutshwa, i-graphene inendawo ethize ephezulu, kanye nomphumela we-Π-Π Ngakho-ke, ukuthi ungayenza kanjani i-graphene enze uhlelo oluhle lokuhlakazeka futhi usebenzise ngokugcwele ukusebenza kwalo okuhle kuyinkinga esemqoka edinga ukuxazululwa kuhlelo lokusebenza olusakazekile lwe-graphiene.
