Emhlabeni wokugcinwa kwamandla, amabhethri adlala indima ebalulekile ekunikeni amandla izimpilo zethu zansuku zonke. Ngokukhula kwesidingo semithombo yamandla avuselelekayo nezimoto zikagesi, isidingo samabhethri asebenza kahle kakhulu asikaze sibe sikhulu. Ababili abaqhudelana kule nkundla ibhethri ye-ion ye-sodium engu-75Ah kanye nebhethri ye-lithium engu-100Ah. Ake sihlolisise lobu buchwepheshe obubili futhi sibone ukuthi buhlangana kanjani.
Amabhethri e-sodium ion abelokhu ethola ukunakwa njengendlela engase ibe enye yamabhethri e-lithium-ion. Enye yezinzuzo ezibalulekile zamabhethri e-sodium ion ukuchichima kwe-sodium, okuwenza abe inketho esimeme futhi engabizi kakhulu. Ukwengeza, amabhethri e-sodium ion anganikeza ukuminyana kwamandla okuphezulu uma kuqhathaniswa namabhethri e-lithium-ion, okungenzeka anikeze amandla ahlala isikhathi eside kuphakheji elincane.
Ngakolunye uhlangothi, amabhethri e-lithium abengamandla amakhulu emakethe yokugcina amandla iminyaka. Ukuminyana kwabo okuphezulu kwamandla, impilo yomjikelezo omude, namandla okushaja okusheshayo kubenze bakwazi ukukhetha ezinhlelweni eziningi, okuhlanganisa izimoto zikagesi nezinhlelo zokugcina igridi. Ibhethri ye-lithium engu-100Ah, ikakhulukazi, inikeza umthamo omkhulu, okwenza ifaneleke izinhlelo zokusebenza ezidingeka kakhulu ezidinga ukuphuma kwamandla okuqhubekayo.

Uma uqhathanisa lokhu kokubili, kubalulekile ukucabangela izici ezifana nokuminyana kwamandla, impilo yomjikelezo, izindleko, nomthelela wendawo. Nakuba amabhethri e-sodium ion ebonisa isithembiso mayelana nokusimama kanye nokuminyana kwamandla, asesezigabeni zokuqala zokuthuthuka futhi angase angakafani nokusebenza kwamabhethri e-lithium. Ngakolunye uhlangothi, amabhethri e-lithium anerekhodi eliqinisekisiwe futhi athuthuka ngokuqhubekayo ngokwezindleko nokusimama.
Ekugcineni, ukukhetha phakathi kwebhethri le-ion ye-sodium engu-75Ah nebhethri ye-lithium engu-100Ah kuzoncika ezidingweni ezithile zohlelo lokusebenza. Kulabo abafuna inketho esimeme kakhudlwana futhi enamandla amakhulu wokuminyana kwamandla, amabhethri e-sodium ion angase acatshangelwe. Kodwa-ke, kuzinhlelo zokusebenza ezidinga ukusebenza okuphezulu nokuthembeka, amabhethri e-lithium ahlala eyinketho ephezulu.
Njengoba ubuchwepheshe buqhubeka nokuthuthuka, womabili amabhethri e-sodium ion kanye ne-lithium azobona ukuthuthuka okwengeziwe, okuwenza ancintisane nakakhulu emakethe yokugcina amandla. Noma ngabe i-sodium ion noma i-lithium, ikusasa lokugcina amandla liqhakazile, nabo bobabili ubuchwepheshe budlala indima ebalulekile ekunikezeni amandla umhlaba ube nekusasa elizinzile.
