Lintlha tsa mantlha mabapi le libeteri tsa sodium-ion
Libetri tsa sodium-ion ke mofuta oa betri ea bobeli (e nchafatsoang hape) e sebelisang li-ion tsa sodium (Na⁺) joalo ka bajari ba litefiso. Molao-motheo oa bona oa ho sebetsa o tšoana le oa libeteri tsa lithium-ion: nakong ea ho tjhaja le ho ntša, li-ion tsa sodium shuttle pakeng tsa cathode le anode ka electrolyte, ho nolofalletsa ho boloka matla le ho lokolloa.
·Lisebelisoa tsa mantlha: Hangata cathode e sebelisa li-oxide tse layered, metsoako ea polyanionic, kapa li-analogues tse putsoa tsa Prussia; anode haholo-holo e entsoe ka k'habone e thata kapa k'habone e bonolo; electrolyte ke tharollo ea letsoai la sodium.
·Khōlo ea Theknoloji: Lipatlisiso li qalile lilemong tsa bo-1980, 'me tsoelo-pele ea morao-rao ea thepa le mekhoa e ntlafalitse haholo matla a matla le bophelo ba potoloho, e leng se etsang hore khoebo e khonehe le ho feta.
Libetri tsa Sodium-ion Khahlanong le Libetri tsa Lithium-ion: Liphapang tsa Bohlokoa le Melemo
Leha libetri tsa sodium-ion li arolelana sebopeho se ts'oanang le libeteri tsa lithium-ion, li fapana haholo ka thepa le maemo a ts'ebeliso:
| Papiso Dimension | Libetri tsa sodium-ion | Libetri tsa lithium-ion |
| Bongata ba Mohlodi | Sodium e ngata (2.75% karolong ea Lefatše) 'me e ajoa haholo | Lithium ea haella (0.0065%) 'me e shebane le libaka |
| Litšenyehelo | Litsenyehelo tse tlase tsa thepa e tala, phepelo e tsitsitseng haholoanyane | Ho feto-fetoha ha theko e phahameng bakeng sa lithium, cobalt, le lisebelisoa tse ling, tse itšetlehileng ka thepa e tsoang linaheng tse ling |
| Matla a Matla | Tlase (120-160 Wh/kg) | Holimo (200-300 Wh/kg) |
| Tshebetso ea Mocheso o Tlase | Ho boloka matla >80% ho -20℃ | Ts'ebetso e mpe ka mocheso o tlase, bokhoni bo fokotseha habonolo |
| Polokeho | Ho tsitsisa ha mocheso o phahameng, ho hanyetsa ho feta tekano / ho tsoa | E hloka taolo e tiileng ea likotsi tsa ho baleha ha mocheso |
Melemo ea mantlha ea libeteri tsa sodium-ion:
1.Theko e tlaase le Tšebeliso ea Mohloli: Sodium e fumaneha haholo metsing a leoatle le liminerale, e fokotsa ho itšetleha ka litšepe tse fokolang le ho fokotsa litšenyehelo tsa nako e telele ka 30% -40%.
2. Polokeho e Phahameng le Botsoalle ba Tikoloho: E lokolohile tšilafalong ea tšepe e boima, e tsamaellanang le lisebelisoa tse sireletsehileng tsa electrolyte, 'me e loketse ho boloka matla a maholo.
3. Wide Temperature Range Ho ikamahanya le maemo: Ts'ebetso e ntle haholo maemong a mocheso o tlase, e loketseng libaka tse batang kapa lits'ebetso tsa polokelo ea matla kantle.
Litebello tsa Ts'ebeliso ea Libetri tsa Sodium-ion
Ka tsoelo-pele ea theknoloji, libeteri tsa sodium-ion li bontša bokhoni bo boholo libakeng tse latelang:
1. Litsamaiso tse kholo tsa polokelo ea matla (ESS):
E le tharollo e tlatselletsang bakeng sa moea le matla a letsatsi, theko e tlase ea libeteri tsa sodium-ion le nako e telele ea bophelo li ka fokotsa ka katleho litšenyehelo tse lekantsoeng tsa motlakase (LCOE) le ho ts'ehetsa ho kuta.
2. Likoloi tsa Motlakase tsa lebelo le tlase le Mabili a Mabeli:
Maemong a nang le litlhoko tse tlase tsa matla a matla (mohlala, libaesekele tsa motlakase, likoloi tsa thepa), libeteri tsa sodium-ion li ka nka sebaka sa libeteri tsa lead-acid, tse fanang ka melemo ea tikoloho le moruo.
3. Backup Power le Base Station Energy Storage:
Ts'ebetso ea bona e pharaletseng ea mocheso e ba etsa hore ba tšoanelehe bakeng sa litlhoko tsa matla a bekapo lits'ebetsong tse sa tsotelleng mocheso joalo ka liteishene tsa puisano le litsi tsa data.
Mekhoa ea Tsoelo-pele ea Bokamoso

·Lintho Tse Ncha: Ho hlahisa li-cathodes tse nang le matla a phahameng (mohlala, li-oxide tsa mofuta oa O3) le lisebelisoa tsa nako e telele tsa anode ho eketsa matla a matla ho feta 200 Wh / kg.
·Tshebetso ea ho ntlafatsa: Ho sebelisa mela ea tlhahiso ea betri ea lithium-ion e holileng ho holisa tlhahiso ea betri ea sodium-ion le ho fokotsa litšenyehelo.
·Katoloso ea Kopo: Ho tlatselletsa libeteri tsa lithium-ion ho aha potefolio ea theknoloji ea polokelo ea matla e fapaneng.
