Ukuqonda Ingozi Eqhumayo Yamabhethri e-Polymer Lithium-Ion

Ngokusekelwe ohlotsheni lwe-electrolyte esetshenzisiwe, amabhethri e-lithium-ion ahlukaniswa amabhethri e-lithium-ion awuketshezi (LIB) namabhethri e-lithium-ion e-polymer (PLB), aziwa nangokuthi amabhethri e-lithium-ion epulasitiki.

Ama-PLB asebenzisa izinto ezifanayo ze-anode ne-cathode njengamabhethri e-lithium-ion e-lithium, okuhlanganisa i-lithium cobalt oxide, i-lithium manganese oxide, izinto ze-ternary, ne-lithium iron phosphate ye-cathode, ne-graphite ye-anode. Umehluko omkhulu usekusetshenzisweni kwe-electrolyte: Ama-PLB athatha indawo ye-electrolyte ewuketshezi nge-polymer electrolyte eqinile, engaba "yomile" noma "i-gel-like." Ama-PLB amaningi okwamanje asebenzisa i-polymer gel electrolyte.

Manje, umbuzo uphakama: ingabe amabhethri e-lithium-ion e-polymer aqhuma ngempela? Uma kubhekwa ubukhulu bawo obuncane nesisindo esilula, ama-PLB asetshenziswa kakhulu kuma-laptops, ama-smartphones, kanye nezinye izinto zikagesi eziphathwayo. Ngala madivaysi avame ukuqhutshwa, ukuphepha kwawo kubaluleke kakhulu. Ngakho-ke, kuthembeke kangakanani ukuphepha kwama-PLB, futhi abeka engcupheni yokuqhuma?

1. Ama-PLB asebenzisa i-electrolyte efana nejeli, ehlukile ku-electrolyte ewuketshezi kumabhethri e-lithium-ion. Le electrolyte efana nejeli ayibilisi noma ikhiqize igesi eningi, ngaleyo ndlela iqede ukuqhuma okunobudlova okungenzeka.
2. Amabhethri e-lithium ngokuvamile afika nebhodi lokuvikela kanye nolayini ovimbela ukuqhuma ukuze aphephe. Nokho, ukusebenza kwabo kungase kulinganiselwe ezimweni eziningi.
3. Ama-PLB asebenzisa amaphakheji epulasitiki e-aluminium aguquguqukayo, ngokuphambene ne-casing yensimbi yamaseli awuketshezi. Uma kunezinkinga zokuphepha, zivame ukuvuvukala kunokuba ziqhume.
4. I-PVDF, njengempahla yohlaka lwama-PLB, isebenza kahle kakhulu.

Izinyathelo Zokuphepha zama-PLB:

• Umjikelezo omfushane: Ubangelwa izici zangaphakathi noma zangaphandle, ngokuvamile ngesikhathi sokushaja. Ukungahlangani kahle phakathi kwamapuleti ebhethri nakho kungaholela kumasekhethi amafushane. Nakuba amabhethri amaningi e-lithium-ion eza namasekhethi avikelayo kanye nemigqa elwa nokuqhuma, lokhu kungase kungasebenzi ngaso sonke isikhathi.
• Ukushajwa ngokweqile: Uma i-PLB ishajwa nge-voltage ephezulu kakhulu isikhathi eside, ingabangela ukushisa kwangaphakathi nokwakheka kwengcindezi, okuholela ekwandeni nokugqabuka. Ukushajwa ngokweqile kanye nokushajwa okujulile kungalimaza ngendlela engenakulungiseka ukwakheka kwamakhemikhali ebhethri, kuthinte ngokuphawulekayo ubude bayo bempilo.

I-lithium iyasebenza kakhulu futhi ingabamba umlilo kalula. Ngesikhathi sokushaja nokukhipha, ukushisisa okuqhubekayo kwebhethri nokwandiswa kwamagesi akhiqizwayo kungakhuphula ukucindezela kwangaphakathi. Uma i-casing yonakalisiwe, ingaholela ekuvuzeni, emlilweni, noma ngisho nokuqhuma. Nokho, ama-PLB maningi amathuba okuthi avuvuke kunokuqhuma.

Izinzuzo zama-PLBs:

1. I-voltage ephezulu yokusebenza ngeseli ngalinye.
2. Ukuminyana komthamo omkhulu.
3. Ukuzikhulula okuncane.
4. Impilo yomjikelezo omude, imijikelezo engaphezu kuka-500.
5. Awukho umphumela wenkumbulo.
6. Ukusebenza kahle kokuphepha, kusetshenziswa amaphakheji epulasitiki e-aluminium aguquguqukayo.
7. Izacile kakhulu, ingangena ezikhaleni ezilingana nekhadi lesikweletu.
8. I-Lightweight: Asikho isidingo se-casing yensimbi.
9. Umthamo omkhulu uma uqhathaniswa nosayizi olinganayo wamabhethri e-lithium.
10. Ukumelana okuphansi kwangaphakathi.
11. Izici ezinhle zokukhipha.
12. Idizayini yebhodi yokuvikela eyenziwe lula.

Ukungalungi kwama-PLBs:

1. Izindleko zokukhiqiza eziphezulu.
2. Isidingo sokujikeleza kokuzivikela.
