Ekugcineni, ukulawulwa kwekhwalithi eqinile kuUkukhiqizwa Kwezinto ze-AnodeKuhunyushwa othembeni, ukuphepha, kanye nokusebenza okubonakalayo. Lokhu kufaka phakathi ukukhethwa kwezinto ezibonakalayo ezibonakalayo, Ukulawulwa kwenqubo okuqondile (ukuxuba, ukuhlanganisa, ukwelashwa okushisa, ukuvezwa), nokuhlolwa okuphelele (Ukuhlolwa kwamakhemikhali, ukuhlolwa kwe-electrochemical,Ukuhlolwa kwesikhathi esideamaphrothokholi). Kwabathengi bathola lezi zinto ezibucayi, abambisene nomenzi ababeka phambili futhi abangakhombisa ukulawulwa kwekhwalithi eqinile kubaluleke kakhulu ekugwemeni ukwehluleka okubizayo kanye nokuqinisekisa ukuphumelela kokusebenza. Ukuzibophezela kwethu kuIfektri ye-electrode ye-professional graphiteyakhelwe kulesi sisekelo sekhwalithi.

Ukukhukhuleka okusemqoka ngezinto zokusetshenziswa kwe-anode:

• Le khasiingomayi-I-electrodelapho i-oxidation (ukulahleka kwama-elektroni) kwenzeka, kuyilaphoIKathodeyilapho ukwehliswa (ukuzuza kwama-elektroni) kwenzeka.
• Amandla e-electrodeiyalainsimbi yanama iniiba yiingomangombhangqwana we-galvanic; eyodwa enokubi ngokwengeziwe-ngaba namandlaama-corlode akhetha.
• I-Anodes (I-Zinc Anode, I-Aluminium Anode, I-Magnesium Anode) Vikela abaluleke kakhuluizinsimbi (IKathode) Ngokulungisa esikhundleni salokho, inqubo ibizwa ngokuthiUkuvikelwa kweCathodic.
• I-Zinc Anodezithembekile ngaphakathiamanzi kasawoti; I-Aluminium Anodenikeza ngaphezuluokukhiqizaphakathi kwa-amanzi kasawotiKepha dinga ukulawulwa kwekhwalithi ngokucophelela;I-Magnesium Anodehlinzeka okuphezulu-ngaba namandlaIlungeleamanzi amashaKepha i-corrode ngokushesha.
• I-graphitekubusaimpahla ye-anodephakathi kwa-Amabhethri e-li-ionNgenxa yokuhle kwayookukhiqiza, impilo yomjikelezo, nezindleko, inika amandla i-lithiumihhashiIsitoreji ngeukuboshwa.
• Silicon nezinye izinto ezithuthukisiwe (uhlobo, LTO,ama-metal oxides) athuthukiswe njengobaIzinto ze-anodeOkokuphakamaokukhiqizanoma ukushaja ngokushesha.
• Le khasiIndwangu yeKathode(imvamisa i-lithiumama-metal oxidesLike LCO, NMC, LFP) lithinta kakhulu ibhethriamandla kagesi, okukhiqiza, ukuphepha, nezindleko.
• Ukukhethaizinto ezinhle kakhulu ongazisebenzisayeingomaIncike kakhulu kwi-ngaba namandla, okukhiqiza, imvelo (amanzi kasawotivs.amanzi amasha), izindleko, kanye nokuphila okudingekayo.
• Ukulawulwa kwekhwalithi okuqinile ngesikhathiUkukhiqizwa Kwezinto ze-Anodekubalulekile ekuqinisekiseni ukusebenza okungaguquki, ukuvimbela ukwehluleka ngaphambi kwesikhathi (ukugqwala, ukuwohloka kwelanga), nokuqinisekisa ukuphepha kuzo zombiliI-Abode ehlanganyelwekanye nezinhlelo zebhethri.
