Iibhetri zesodium-ion: Ngaba zingcono kuneebhetri ze-lithium?
Kwiminyaka yakutshanje, kukho umdla okhulayo kwiibhetri ze-sodium-ion njengezinye iindlela ezinokuthi zenziwe kwiibhetri ze-lithium-ion.Njengoko imfuno yezisombululo zokugcina amandla iqhubeka nokunyuka, abaphandi kunye nabavelisi bahlola amandla eebhetri ze-sodium-ion ukuhlangabezana neemfuno ezikhulayo zamashishini ahlukeneyo, kubandakanywa izithuthi zombane, ukugcinwa kwamandla avuselelekayo kunye ne-elektroniki ephathekayo.Oku kuye kwavusa ingxoxo malunga nokuba iibhetri ze-sodium-ion ziphezulu kuneebhetri ze-lithium-ion.Kweli nqaku, siza kuphonononga umahluko ophambili phakathi kweebhetri ze-sodium-ion kunye ne-lithium-ion, i-pros and cons of each, kunye nokubanakho kweebhetri ze-sodium-ion ukodlula iibhetri ze-lithium-ion.
Iibhetri ze-sodium-ion, njengeebhetri ze-lithium-ion, zizixhobo zokugcina amandla ezihlawulelwayo ezisebenzisa iinkqubo ze-electrochemical ukugcina nokukhulula amandla.Umahluko omkhulu ulele kwizinto ezisetyenziselwa i-electrodes kunye ne-electrolyte.Iibhetri ze-lithium-ion zisebenzisa iikhompawundi ze-lithium (ezifana ne-lithium cobalt oxide okanye i-lithium iron phosphate) njenge-electrodes, ngelixa iibhetri ze-sodium-ion zisebenzisa i-sodium compounds (njenge-sodium cobalt oxide okanye i-sodium iron phosphate).Lo mahluko kwizinto eziphathekayo unempembelelo enkulu ekusebenzeni kwebhetri kunye neendleko.
Enye yeenzuzo eziphambili zeebhetri ze-sodium-ion kukuba i-sodium ininzi kakhulu kune-lithium kwaye ayibizi kakhulu.Isodium yenye yezona zinto zininzi emhlabeni kwaye inexabiso eliphantsi ukuyikhupha kunye nokusebenza xa kuthelekiswa ne-lithium.Olu buninzi kunye neendleko eziphantsi zenza iibhetri ze-sodium-ion zibe yinto ekhangayo kwizicelo zokugcinwa kwamandla amakhulu, apho ukuphumelela kweendleko kuyinkalo ephambili.Ngokwahlukileyo, unikezelo oluncinci lwe-lithium kunye neendleko eziphezulu ziphakamisa inkxalabo malunga nokuzinza kwexesha elide kunye nokufikeleleka kweebhetri ze-lithium-ion, ngakumbi njengoko imfuno yokugcina amandla iqhubeka ikhula.
Enye inzuzo yeebhetri ze-sodium-ion yikhono labo lokuxinana kwamandla aphezulu.Ubuninzi bamandla bubhekisa kumthamo wamandla anokugcinwa kwibhetri yomthamo okanye ubunzima obunikiweyo.Ngelixa iibhetri ze-lithium-ion ngokwesiko zibonelela ngamandla aphezulu amandla kunezinye iintlobo zeebhetri ezinokutshajwa, inkqubela phambili yamva nje kwitekhnoloji yebhetri ye-sodium-ion ibonise iziphumo ezithembisayo ekufezekiseni amanqanaba okuxinana kwamandla.Olu luphuhliso olubalulekileyo njengoko uxinaniso lwamandla aphezulu lubalulekile ekwandiseni uluhlu lwezithuthi zombane kunye nokuphucula ukusebenza kombane ophathwayo.
Ukongeza, iibhetri ze-sodium-ion zibonisa ukuzinza okuhle kwe-thermal kunye neempawu zokhuseleko.Iibhetri ze-lithium-ion zaziwa ngokuthanda ukubaleka kwe-thermal kunye neengozi zokhuseleko, ngakumbi xa zonakaliswe okanye zibonakaliswe kumaqondo aphezulu.Ngokuthelekisa, iibhetri ze-sodium-ion zibonisa ukuzinza okungcono kwe-thermal kunye nomngcipheko ophantsi wokubaleka kwe-thermal, okwenza kube yinto ekhuselekileyo yokukhetha kwizicelo ezahlukeneyo.Olu khuseleko luphuculweyo lubaluleke kakhulu kwizithuthi zombane kunye neenkqubo zokugcina amandla ezimileyo, apho umngcipheko wokutsha kwebhetri kunye nokudubula kufuneka kuncitshiswe.
Ngaphandle kwezi nzuzo, iibhetri zesodium-ion nazo zinemida ethile xa kuthelekiswa neebhetri ze-lithium-ion.Omnye wemingeni ephambili ngumbane ophantsi kunye namandla athile ebhetri ye-sodium-ion.Amandla ombane asezantsi aphumela ekuphumeni kwamandla asezantsi kwiseli nganye, nto leyo echaphazela ukusebenza kunye nokusebenza kakuhle kwenkqubo yebhetri.Ukongezelela, iibhetri ze-sodium-ion ngokubanzi zinamandla athile aphantsi (amandla agcinwe ngeyunithi ubunzima) kuneebhetri ze-lithium-ion.Oku kunokuchaphazela ubuninzi bamandla kunye nokusebenziseka kweebhetri ze-sodium-ion kwizicelo ezithile.
Omnye umda weebhetri ze-sodium-ion bubomi babo bomjikelezo kunye nekhono lokulinganisa.Ubomi bomjikelo bubhekiselele kwinani lentlawulo kunye nemijikelo yokukhupha ibhetri enokuthi idlule kuyo phambi kokuba umthamo wayo wehle kakhulu.Ngelixa iibhetri ze-lithium-ion ziyaziwa ngobomi bazo bomjikelo omde, iibhetri zesodium-ion ziye zabonisa ngokwembali ubomi bomjikelo ophantsi kunye nentlawulo ecothayo kunye namazinga okukhutshwa.Nangona kunjalo, uphando oluqhubekayo kunye neenzame zophuhliso zijolise ekuphuculeni ubomi bomjikelezo kunye nomthamo wezinga leebhetri ze-sodium-ion ukwenza ukuba bakhuphisane ngakumbi neebhetri ze-lithium-ion.
Zombini iibhetri ze-sodium-ion kunye ne-lithium-ion zinemingeni yazo xa kuziwa kwimpembelelo yendalo.Nangona i-sodium ininzi kwaye ingabizi kakhulu kune-lithium, ukutsalwa kunye nokucutshungulwa kwee-sodium compounds kusenokuba neempembelelo zokusingqongileyo, ngakumbi kwiindawo apho izibonelelo ze-sodium zigxininiswe.Ukongezelela, ukuveliswa kunye nokulahlwa kweebhetri ze-sodium-ion kufuna ukuqwalaselwa ngenyameko kwimimiselo yokusingqongileyo kunye nezenzo ezizinzileyo zokunciphisa impembelelo yazo kwindalo.
Xa kuthelekiswa nokusebenza ngokubanzi kunye nokufaneleka kweebhetri ze-sodium-ion kunye ne-lithium-ion, kubalulekile ukuqwalasela iimfuno ezithile zezicelo ezahlukeneyo.Ngokomzekelo, kwiinkqubo ezinkulu zokugcina amandla, apho iindleko-ukusebenza kunye nokuzinza kwexesha elide zizinto eziphambili, iibhetri ze-sodium-ion zinokunika isisombululo esikhangayo ngenxa yobuninzi be-sodium kunye neendleko eziphantsi.Ngakolunye uhlangothi, iibhetri ze-lithium-ion zisenokuhlala zikhuphisana kwizicelo ezifuna ukuxinana kwamandla aphezulu kunye nokuhlawuliswa ngokukhawuleza kunye namazinga okukhutshwa, njengezithuthi zombane kunye ne-elektroniki ephathekayo.
Isishwankathelo, ingxabano malunga nokuba iibhetri ze-sodium-ion ziphezulu kuneebhetri ze-lithium-ion ziyinkimbinkimbi kwaye zininzi.Ngelixa iibhetri ze-sodium-ion zibonelela ngeenzuzo ngobuninzi, iindleko, kunye nokhuseleko, nazo zijongene nemingeni ekuxininiseni kwamandla, ubomi bomjikelezo, kunye nokukwazi ukulinganisa.Njengoko uphando lweteknoloji yebhetri kunye nophuhliso luqhubeka luqhubela phambili, iibhetri ze-sodium-ion zinokuthi zikhuphisane ngakumbi neebhetri ze-lithium-ion, ngakumbi kwizicelo ezithile apho iimpawu zabo ezizodwa zifanelekile.Ekugqibeleni, ukhetho phakathi kweebhetri ze-sodium-ion kunye ne-lithium-ion ziya kuxhomekeka kwiimfuno ezithile zesicelo ngasinye, ukuqwalaselwa kweendleko kunye neempembelelo zokusingqongileyo, kunye nokuqhubela phambili okuqhubekayo kwiteknoloji yebhetri.
