Molao-motheo oa tlhahiso ea betri ea sodium-ion

Libetri tsa sodium-ion (SIBs ka nako e khutšoanyane) ke libeteri tsa polokelo ea matla tse khonang ho ts'oaroa hape tse nang le melemo ea matla a phahameng, boima bo bobebe, mocheso o fokolang oa mocheso, ho itšehla thajana le litšenyehelo tse tlaase. Sesebelisoa se ntlafalitsoeng sa SIBs se ka nka sebaka sa libeteri tsa graphene lithium tsa setso se tla khothaletsa ka matla tšebeliso ea matla a batho.

Ka kakaretso, molao-motheo oa ts'ebetso ea li-SIB ke tse latelang: nakong ea ho tjhaja / ho lahla, khatello ea Na + holim'a li-electrode tsa SIB e eketseha / ea fokotseha, 'me ka ts'ebeliso ea meroalo le liphetoho ho li-electrode tsa tsona, ho lefella oxidation / ho fokotsa qetellong ho hlahisa li-hydrogen bond. . Liphetoho tsena li phethoa ke lijana tse peli tse fapaneng tsa sele ea electrochemical. Setshelo se le seng se fapaneng se na le Na + electrolyte, 'me sejana se seng se fapaneng se na le mokelikeli oa electrode.

E le ho finyella litlhoko tsa hona joale tse phahameng le tsa boleng ba lihlahisoa tsa elektroniki, bafuputsi ba atisa ho sebelisa li-electrode tse kobehileng ho fokotsa boholo ba betri ea SIBs. Ha ho bapisoa le mefuta e meng ea betri ea lithium-ion, li-electrode tse kobehileng li ka fetisetsa Na + pakeng tsa lijana tse peli ka mokhoa o atlehileng haholoanyane. Li-SIB li ka boela tsa ntlafatsoa hore e be li-electrode tsa nano-copolymer, tse netefatsang matla a phahameng le ts'ebetso e tsitsitseng ea betri nakong ea ts'ebetso e nepahetseng.

Melemo le mathata a 20

molemo:

1. Libetri tsa sodium-ion li na le matla a holimo 'me li ka boloka matla a mangata, e leng ho etsang hore li be bonolo ho li-application tsa matla a maholo;

2. Li-SIB li nyenyane ka boholo le boima bo bobebe, tse ka bolokang sebaka le boima ba 'mele;

3. E na le ho hanyetsa mocheso o motle le botsitso bo phahameng ba mocheso;

4. Sekhahla se senyenyane sa ho itlhatsoa, ​​​​ho boloka matla a nako e telele;

5. Li-SIB li na le tšireletso e molemo ho feta libeteri tse ling 'me ha li na monyetla oa ho hotetsa polarization ea metsi;

6. E na le bokhoni bo botle ba ho tsosolosa hape e ka sebelisoa hangata;

7. Li-SIB li na le litšenyehelo tse tlaase 'me li boloka litšenyehelo tsa thepa tlhahisong.

khaello:

1. Li-SIB li na le motlakase o fokolang tlas'a maemo a tloaelehileng 'me ha lia lokela ho sebelisoa lits'ebetsong tse phahameng tsa motlakase;

2. Hangata li-SIB li na le conductivity e phahameng, e hlahisang tefiso e tlaase le katleho ea ho ntša;

3. Ho hanyetsa ka hare ho phahame, 'me lits'ebetso tsa ho tjhaja le ho ntša li tla baka tahlehelo e kholo;

4. Thepa ea elektrode e tsitsitse ebile ho thata ho e boloka ka nako e telele;

5. Ka linako tse ling libeteri li na le tekanyo e phahameng ea ho hlōleha tlas'a mocheso o phahameng le maemo a thata;

6. Matla a fokotsehileng a li-SIB a tla baka tahlehelo e kholo nakong ea ho potoloha;

7. Ha se lihlahisoa tsohle tsa elektronike tse ka sebelisang libeteri tsa sodium-ion. Ka mohlala, lisebelisoa tse ling li hloka ho boloka motlakase o itseng pele li ka sebetsa hantle.
