Isimiso sokukhiqiza ibhethri le-sodium-ion

Amabhethri e-sodium-ion (ama-SIB amafushane) angamabhethri okugcina amandla aphinde ashajwe anezinzuzo zomthamo omkhulu, isisindo esilula, ukukhiqiza ukushisa okuphansi, ukuzikhipha okuphansi, kanye nezindleko eziphansi. Idivayisi ethuthukisiwe yama-SIB ingangena esikhundleni samabhethri e-lithium e-Graphene azokhuthaza ngamandla ukusetshenziswa kwamandla okugaywa kabusha kwabantu.

Ngokuvamile, isimiso sokusebenza sama-SIB simi kanje: ngesikhathi sokushaja/ukuchithwa, ukugcwala kwe-Na+ kuma-electrode ama-SIBs kuyanda/kwehla, futhi ngokusetshenziswa kwemithwalo nezinguquko kuma-electrode awo, ukushaja oxidation/ukunciphisa ekugcineni kukhiqiza amabhondi e-hydrogen. . Lokhu kusabela kuqedwa iziqukathi ezimbili eziphambene zeseli ye-electrochemical. Isitsha esisodwa esiphambene siqukethe i-Na+ electrolyte, kanti esinye isitsha esiphambene siqukethe uketshezi lwe-electrode.

Ukuze kuhlangatshezwane nezidingo zamanje zomthamo ophezulu kanye nevolumu yemikhiqizo kagesi, abacwaningi bavamise ukusebenzisa ama-electrode agobile ukuze behlise usayizi webhethri wama-SIB. Uma kuqhathaniswa nezinye izinhlobo zebhethri ye-lithium-ion, ama-electrode agobile angadlulisela i-Na+ phakathi kweziqukathi ezimbili ngendlela ephumelela kakhudlwana. Ama-SIB angabuye athuthukiswe abe ama-electrode e-nano-copolymer, aqinisekisa umthamo ophezulu nokusebenza komthamo okungashintshi webhethri phakathi nezinqubo zokunemba.

20 okuhle nokubi

inzuzo:

1. Amabhethri e-sodium-ion anomthamo ophezulu futhi angagcina amandla amaningi, awenze afaneleke kakhulu ekufakweni komthamo omkhulu;

2. Ama-SIB mancane ngosayizi futhi alula ngesisindo, angonga isikhala nesisindo;

3. Inokumelana nokushisa okuhle kanye nokuzinza okuphezulu kwezinga lokushisa;

4. Izinga elincane lokuzikhipha, isitoreji samandla esihlala isikhathi eside;

5. Ama-SIB anokuphepha okungcono kunamanye amabhethri futhi mancane amathuba okuthi akhele ku-polarization yoketshezi;

6. Inekhono elihle lokugaywa kabusha futhi ingasetshenziswa kabusha izikhathi eziningi;

7. Ama-SIB anezindleko eziphansi futhi onga izindleko zezinto ezibonakalayo ekukhiqizeni.

ukushiyeka:

1. Ama-SIB ane-voltage ephansi ngaphansi kwezimo ezijwayelekile futhi awafanele ukusetshenziswa ezinhlelweni zamandla kagesi aphezulu;

2. Ama-SIB ngokuvamile ane-conductivity ephezulu, okuholela ekushajisweni okuphansi nokusebenza kahle kokukhipha;

3. Ukumelana kwangaphakathi kuphezulu, futhi izinqubo zokushaja nokukhipha zizobangela ukulahlekelwa okukhulu;

4. Izinto ze-electrode azinzile futhi kunzima ukuzigcina isikhathi eside;

5. Amabhethri kwesinye isikhathi anezinga eliphezulu lokuhluleka ngaphansi kwamazinga okushisa aphezulu nezimo ezinzima;

6. Amandla ancishisiwe ama-SIB azodala ukulahlekelwa okukhulu ngesikhathi sokujikeleza;

7. Akuyona yonke imikhiqizo kagesi engasebenzisa amabhethri e-sodium-ion. Isibonelo, amanye amadivaysi adinga ukugcina amandla kagesi athile ngaphambi kokuthi asebenze kahle.
