Ukuqanjwa kabusha kwamandla: Izinzuzo zobuchwepheshe zebhethri ye-sodium-ion engu-220Ah ziphazamisa imakethe yebhethri ye-LiFePO4 evamile.

Ngokukhula kwesidingo sanamuhla samandla avuselelekayo, ukusungulwa kobuchwepheshe bebhethri sekube ukhiye wokuthuthukisa ikusasa. Muva nje, ibhethri elisha le-sodium-ion engu-220Ah lidonse ukunaka kwabantu abaningi embonini, futhi izinzuzo zalo zobuchwepheshe zimemezela ukuchithwa kwemakethe yebhethri ye-LiFePO4 evamile.

Idatha ekhishwe ngalesi sikhathi ibonisa ukuthi ibhethri entsha ye-sodium-ion ingcono kunebhethri ye-LiFePO4 ekuhlolweni okuningi kokusebenza, ikakhulukazi mayelana nezinga lokushisa lokushaja, ukujula kokukhishwa kanye nokugcinwa kwezinsiza. Amabhethri e-sodium-ion angashajwa ngokuphephile ezindaweni eziphansi njenge-minus 10 degrees Celsius, okupholile ngo-10 degrees kunomkhawulo wokususa wamabhethri e-LiFePO4. Lokhu kuphumelela kwenza amabhethri e-sodium-ion asetshenziswe kabanzi ezindaweni ezibandayo.

Okuhlaba umxhwele nakakhulu ukuthi amabhethri e-sodium-ion angafinyelela ukujula kokukhipha okungu-0V. Lesi sici asigcini nje ngokuthuthukisa kakhulu ukusetshenziswa kwebhethri, kodwa futhi sisiza ukuthuthukisa impilo yonke yebhethri. Ngokuphambene, ukujula kokukhishwa kwamabhethri e-LiFePO4 kuvame ukusetha ku-2V, okusho ukuthi amandla amancane atholakala kuzinhlelo zokusebenza ezingokoqobo.

Ngokuphathelene nemithombo yemithombo, amabhethri e-sodium-ion asebenzisa i-sodium element eningi emhlabeni. Le nto inezinqolobane ezinkulu kanye nezindleko eziphansi zezimayini, ngaleyo ndlela iqinisekisa izindleko zokukhiqiza kanye nokuzinza kwebhethri. Amabhethri e-LiFePO4 athembele kuzinsiza ze-lithium ezilinganiselwe futhi angase abhekane nobungozi bokunikezwa ngenxa yemithelela yezwe.

Mayelana nokuphepha, amabhethri e-sodium-ion akalwe ngokuthi “aphephile”. Lokhu kuhlola kusekelwe ekuzinzeni kwabo kwamakhemikhali kanye nesakhiwo sesakhiwo, futhi kulindeleke ukuthi kunikeze abasebenzisi izinga eliphezulu lokuphepha.

Lezi zinzuzo ezibalulekile zobuchwepheshe zibonisa ukuthi amabhethri e-sodium-ion awakwazi nje ukunikeza izixazululo ezisebenza kahle nezithembekile zokugcina amandla, kodwa ubungane bawo bemvelo nokusebenza kahle kwezindleko kuzophinde kukhuthaze ukusetshenziswa kwazo ezimotweni zikagesi, izinhlelo ezinkulu zokugcina amandla, kanye nemishini kagesi ephathekayo. . anhlobonhlobo izicelo ensimini. Njengoba ubuchwepheshe bebhethri ye-sodium-ion bukhula, sinesizathu sokukholelwa ukuthi ikusasa lamandla elisimeme nelisebenza kahle liyeza.
