Yeyiphi imida yobugcisa yeebhetri zesodium-ion?

Iibhetri ze-sodium-ion zibuchwephesha bebhetri obunamandla amakhulu, kodwa basajongene nobunzima kwimveliso yabo kunye nemveliso yobuninzi. Okokuqala, ukubonelela ngezinto ezikrwada ngumba ophambili kwimveliso yebhetri ye-sodium-ion. Nangona imithombo ye-sodium ininzi kakhulu, xa imfuno ye-sodium inyuka ngokukhawuleza njengemfuno ye-lithium, ixabiso layo alinakuqinisekiswa ukuba lizinzile.

Ngelo xesha, i-sodium mining kunye neteknoloji yokucoca ibuyele ngasemva. Emva kwayo yonke loo nto, i-sodium ayizange ifumane ingqwalasela enkulu ngaphambili. Oku kubangele ukunyanzeliswa kwekhonkco lokubonelela okwenza kube nzima ukuhlangabezana neemfuno ezinkulu zokuvelisa ibhetri ye-sodium-ion. Okwesibini, ukulungiswa kwenkqubo yokuvelisa ibhetri ye-sodium-ion nayo ingumngeni.

Inkqubo yokuveliswa kweebhetri ze-sodium-ion idinga ulawulo oluchanekileyo kakhulu. Ukuhlanganiswa kwezinto, ukugquma kunye nokuhlanganisa i-electrode kunye nezinye iikhonkco akufuneki kube yi-sloppy. Ingxaki kukuba ukungazinzi kaninzi kwenzeka kula makhonkco. Oku kuphazamiseka kuya kuchaphazela ukusebenza kwebhetri kunye nobomi kunye nokunyusa iindleko zemveliso.

Okwesithathu, ukhuseleko ngumba ophambili ekufuneka uhoywe ngqalelo ekuvelisweni kweebhetri ze-sodium-ion. Isinyithi se-sodium esetyenziswa kwiibhetri ze-sodium-ion sisebenza kakhulu xa sidibana nomoya kunye namanzi, nto leyo enokubangela ukukhathazeka kokhuseleko. Ngoko ke, amanyathelo akhuselekileyo okhuseleko kufuneka athathwe ngexesha lenkqubo yokuvelisa ukuqinisekisa ukhuseleko ngexesha lokuvelisa kunye nokusetyenziswa kweebhetri ze-sodium-ion.

Ekugqibeleni, iindleko zokuvelisa ngomnye umba omele uqwalaselwe xa uvelisa ubuninzi beebhetri ze-sodium-ion. Xa kuthelekiswa neebhetri ze-lithium-ion ezivuthiweyo, iindleko zokuvelisa iibhetri ze-sodium-ion ziphezulu. Ngakolunye uhlangothi, ixabiso lezinto eziluhlaza, kwelinye icala, ubunzima benkqubo yokuvelisa kunye nokutyalomali kwezixhobo kuya kwandisa iindleko zemveliso.

Eyona ndlela yokunciphisa iindleko zemveliso kukuphumeza imveliso ngobuninzi. Emva kokuba umthamo ufezekisiwe, i-curve yeendleko inokulungiswa. Oku kudala i-paradox. Kuphela xa ixabiso liphantsi kwaye inkunzi yemarike inkulu iya kwenzeka imveliso enkulu enesibindi. Ukuba ixabiso liphezulu kakhulu, imveliso yobuninzi iya kuba ngaphandle kokufikelela. Ukufezekiswa kokuphucula ukusebenza kakuhle kwemveliso kunye nokunciphisa iindleko kusajongene nemida emininzi.
