Imigaqo yokuvelisa ibhetri ye-sodium-ion kunye neenzuzo kunye nokungonakali

Umgaqo wokuvelisa ibhetri ye-sodium-ion

Iibhetri ze-sodium-ion (i-SIBs ngokufutshane) ziibhetri zokugcina amandla ezihlawulelwayo ezineenzuzo zomthamo ophezulu, ubunzima bokukhanya, ukuveliswa kobushushu obuphantsi, ukukhutshwa okuphantsi, kunye neendleko eziphantsi. Isixhobo se-SIBs esiphuhlisiwe sinokuthatha indawo yeebhetri ze-lithium ze-Graphene ziyakukhuthaza ngamandla ukusetyenziswa kwamandla okurisayikilisha kwabantu.

Ngokuqhelekileyo, umgaqo osebenzayo we-SIBs umi ngolu hlobo lulandelayo: ngexesha lokutshaja / ukuchithwa, ukuxinwa kwe-Na + kwi-electrodes ye-SIBs kwandisa / kuncipha, kunye nokusetyenziswa kwemithwalo kunye noshintsho kwi-electrodes yabo, i-oxidation ihlawulise / ukunciphisa ekugqibeleni ivelisa ibhondi ze-hydrogen. . Ezi mpendulo zigqitywe zizikhongozeli ezibini ezichaseneyo zeseli ye-electrochemical. Esinye isikhongozeli esichaseneyo siqulethe i-Na+ electrolyte, kunye nesinye isikhongozeli esichaseneyo siqulethe ulwelo lwe-electrode.

Ukuze kuhlangatyezwane nomthamo ophezulu wangoku kunye neemfuno zevolumu yeemveliso ze-elektroniki, abaphandi bakholisa ukusebenzisa i-electrodes egobileyo ukunciphisa ubungakanani bebhetri yee-SIBs. Xa kuthelekiswa nezinye iintlobo zebhetri ye-lithium-ion, i-electrode egobileyo inokudlulisa i-Na + phakathi kwezikhongozeli ezimbini ngokufanelekileyo. Ii-SIBs nazo zingaphuculwa zibe yi-nano-copolymer electrode, eqinisekisa umthamo ophezulu kunye nokusebenza rhoqo kwamandla ebhetri ngexesha leenkqubo ezichanekileyo.

20 okulungileyo nokubi

inzuzo:

1. Iibhetri ze-sodium-ion zinomthamo ophezulu kwaye ziyakwazi ukugcina amandla amaninzi, okwenza kube lula ngakumbi kwizicelo zomthamo omkhulu;

2. Ii-SIBs zincinci ngobukhulu kwaye zikhaphukhaphu ngobunzima, ezinokugcina indawo kunye nobunzima;

3. Unokumelana nobushushu obuhle kunye nokuzinza okuphezulu kobushushu;

4. Izinga elincinci lokuzikhupha, ukugcinwa kwamandla okuhlala ixesha elide;

5. Ii-SIBs zinokhuseleko olungcono kunezinye iibhetri kwaye azinakwenzeka ukuba zivuthe kwi-polarization yolwelo;

6. Inesakhono esihle sokurisayikilisha kwaye ingaphinda isetyenziswe ngamaxesha amaninzi;

7. Ii-SIB zineendleko eziphantsi kwaye zigcina iindleko zezinto eziphathekayo kwimveliso.

ukusilela:

1. Ii-SIBs zinombane ophantsi phantsi kweemeko eziqhelekileyo kwaye azifanelekanga ukusetyenziswa kwizicelo eziphezulu zombane;

2. Ngokuqhelekileyo ii-SIBs zine-conductivity ephezulu, okubangelwa ukuhlawulwa okuphantsi kunye nokusebenza kakuhle kokukhutshwa;

3. Ukuchasana kwangaphakathi kuphezulu, kwaye iinkqubo zokutshaja kunye nokukhupha ziya kubangela ilahleko enkulu;

4. Izinto ze-electrode aziqinisekanga kwaye kunzima ukuzigcina ixesha elide;

5. Iibhetri ngamanye amaxesha zinezinga eliphezulu lokungaphumeleli phantsi kobushushu obuphezulu kunye neemeko ezinzima;

6. Umthamo oncitshisiweyo wee-SIB uya kubangela ilahleko enkulu ngexesha lokujikeleza;

7. Ayizizo zonke iimveliso ze-elektroniki ezinokusebenzisa iibhetri ze-sodium-ion. Ngokomzekelo, ezinye izixhobo kufuneka zigcine amandla ombane athile ngaphambi kokuba zisebenze kakuhle.
