Isixazululo samandla esizukulwane esisha: 18650-70C ibhethri le-sodium-ion lidlula ibhethri elivamile le-LiFePO4 ekusebenzeni
Engqungqutheleni Yamazwe Ngamazwe Anamandla Aqhubekayo ebanjwe namuhla, ibhethri ye-sodium-ion ebizwa ngokuthi i-18650-70C idonse ukunaka okubanzi kwabahlanganyeli. Ibhethri idlula ubuchwepheshe bebhethri ye-lithium iron phosphate (LiFePO4) ekhona kumapharamitha amaningi okusebenza abalulekile futhi ibhekwa njengentuthuko enkulu emkhakheni wamandla avuselelekayo.
Ukusebenza kwamabhethri e-sodium-ion kuvelele kakhulu ngaphansi kwezimo zokushisa eziphansi kakhulu. Izinga lokushisa layo lokukhipha lingafinyelela ku-minus 40 degrees Celsius, elifaneleka kakhulu ezindaweni ezibandayo kune-minus 30 degrees Celsius yamabhethri e-LiFePO4. Okuhlaba umxhwele nakakhulu ukuthi izinga lokushaja (3C) laleli bhethri le-sodium-ion liphindwe kathathu kunebhethri le-LiFePO4 (1C), futhi izinga lokuphuma (35C) liphindwe izikhathi ezingu-35 kunelekamuva (1C). Ngaphansi kwezimo zokukhishwa kwe-pulse high-load, izinga layo eliphezulu lokukhishwa kwe-pulse (70C) cishe liphindwe izikhathi ezingu-70 kunebhethri ye-LiFePO4 (1C), ebonisa amandla amakhulu okusebenza.
Ngaphezu kwalokho, amabhethri e-sodium-ion angashajwa ngokugcwele ku-0V ngaphandle kokulimaza impilo yebhethri, okubaluleke kakhulu ekweluleni impilo yebhethri. Ngokuphathelene nezinto ezigciniwe zezinto ezibonakalayo, amabhethri e-sodium-ion asebenzisa izinsiza eziningi kakhulu futhi ezingavinjelwe, okusho ukuthi emhlabeni wonke, amabhethri e-sodium-ion azothengeka kakhulu mayelana nokuhlinzekwa kanye nezindleko kunamabhethri e-LiFePO4, anezinsiza ezilinganiselwe ze-lithium. Inzuzo.
Uma kubhekwa ukuthuthukiswa kokusebenza kokuphepha, leli bhethri kuthiwa "liphephile", futhi nakuba amabhethri e-LiFePO4 aye abhekwa kabanzi njengohlobo lwebhethri oluphephile, uma kuqhathaniswa namabhethri amasha e-sodium-ion, lokhu okugcina ngokusobala kuyindinganiso ephephile.
Lokhu kuphumelela kwezobuchwepheshe kunikeza izixazululo zamandla amasha ezimotweni zikagesi, amadivaysi eselula, nezinhlelo ezinkulu zokugcina amandla, futhi kulindeleke ukuthi kubangele izinguquko ezinkulu emakethe yokugcina amandla emhlabeni.
Njengoba uguquko lwamandla luqhubeka nokujula, impumelelo kubuchwepheshe obusha bebhethri buvule umnyango wekusasa elisebenza kahle, eliluhlaza, nelizinze kakhudlwana.
