• IanodeIngaba ii-electrodeapho i-oxidation (ilahleko ye-elektroni) yenzeka, ngelixai-cathodeKulapho kuncitshiswa (inzuzo ye-elektroniki) yenzeka.
• I-electrode enokubakhoHlambayointsimbiibaanodekwisibini esitshatileyo; enye enezinto ezingalungangakunokwenzekaI-corrodes ngokukhethekileyo.
• I-avilas (zinc anode, i-aluminium anode, magnesium afade) Khusela ixabiseke ngakumbiizinyithi (i-cathode) ngokuthintela endaweni yoko, inkqubo ibizwaUkukhuselwa kwe-cathodic.
• I-zinc anodeszinokuthenjwa ngaphakathiamanzi ityiwa; i-aluminium anodesNikeza phezuluamandlangaphakathiamanzi ityiwakodwa funa ulawulo olusemgangathweni;magnesium anodesbonelela phezulukunokwenzekailungeleamanzi amatshakodwa ukhuphe ngokukhawuleza.
• Igrafuyeyona nto iphambiliIzinto ze-AnodengaphakathiI-Li-ion ibhetringenxa yokulungileyoamandla,, ubomi bomjikelo, kunye neendleko, ukuvumela i-lithiumionukugcinwa ngeUkulungelelaniswa.
• I-Silicon kunye nezinye izinto eziphambili (igraphene, LO,izesi zentsimbi) ziyaphuhliswa njengeIzinto ze-Anodengaphezuluamandlaokanye ukutshaja ngokukhawuleza.
• IIzinto ze-Cathodede(ihlala i-lithiumizesi zentsimbiNjenge-lCO, i-NMC, lfp) ibhetriI-Voltage, amandla, ukhuseleko, kunye neendleko.
• Ukukhetha ieyona nto ibalulekileyo ekufuneka uyisebenziseyeanodeixhomekeke kukunokwenzeka, amandla, okusingqongileyo (amanzi ityiwavsamanzi amatsha), iindleko, kunye nokufunwa ngubomi bexesha.
• Ukulawulwa komgangatho ophantsi ngexeshaImveliso ye-Anodeibalulekile ekuqinisekiseni ukusebenza okungaguqukiyo, ukuthintela ukusilela kwangaphambili (i-corrosion, ukonakaliswa) kunye nokuqinisekisa ukhuseleko kuzo zombiniindawo yedinikunye nezicelo zebhetri.
