Uhlalutyo lwendlela yophuhliso lobugcisa be-lithium battery electrolyte
I-1, i-electrolyte yamandla aphezulu
Ukusukela amandla athile aphezulu lolona lwalathiso lophando lwebhetri ye-lithium-ion, ngakumbi xa izixhobo eziphathwayo zithatha ubunzima obuninzi kubomi babantu, uluhlu, lube yeyona ntsebenzo ibalulekileyo yebhetri.
2, i-electrolyte yamandla aphezulu
Okwangoku, ibhetri ye-lithium-ion yorhwebo kunzima ukufikelela kwizinga eliphezulu lokukhutshwa okuzinzileyo, isizathu esibalulekileyo kukuba i-bettery pole indlebe yokufudumeza ishushu, ukuchasana kwangaphakathi okukhokelela kubushushu bebhetri buphezulu kakhulu, buxhomekeke ekubalekeni kwe-thermal. . Ngoko ke, i-electrolyte inokuthintela ibhetri ekufudumezeni ngokukhawuleza ngelixa igcina i-conductivity ephezulu. Kwaye malunga neebhetri ze-lithium zamandla, ukufezekisa ukutshaja ngokukhawuleza kukwayindlela ebalulekileyo yophuhliso lwe-electrolyte.
3, Ubushushu obubanzi be-electrolyte
Ibhetri ilungele ukubola kwe-electrolyte ngokwayo kunye nokuqiniswa kwempendulo yecala phakathi kwezinto eziphathekayo kunye neengxenye ze-electrolyte kwiqondo lokushisa eliphezulu; ngelixa kubushushu obuphantsi kunokubakho i-electrolyte ityuwa yemvula kunye nokuphindaphinda kwe-impedance yefilimu ye-SEI engathandekiyo. Into ebizwa ngokuba yi-electrolyte ebanzi yobushushu kukwenza ibhetri ibe nendawo yokusebenza ebanzi.
4. Ukhuseleko electrolyte
Ukhuseleko lwebhetri lubalulekile ekutshisweni nasekuqhumeni. Okokuqala, ibhetri ngokwayo inokutsha, ngoko ke xa ibhetri igqithise kakhulu, ikhutshwe okanye ifutshane, xa ifumana i-pinprick yangaphandle okanye i-extrusion, kwaye xa ukushisa kwangaphandle kuphezulu kakhulu, kunokubangela izingozi zokhuseleko. Ke ngoko, i-flame retardant sisikhokelo esibalulekileyo sophando lokhuseleko lwe-electrolyte.
5. Umjikelo omde wohlobo lwe-electrolyte
Ekubeni kusekho ubunzima obukhulu bobugcisa ekuhlaziyweni kweebhetri ze-lithium-ion, ngakumbi ekuhlaziyweni kweebhetri ze-lithium zamandla, ukuphucula ubomi bebhetri yindlela enye yokunciphisa le meko. Kukho iingcamango ezimbini ezibalulekileyo zophando zomjikelo omde wohlobo lwe-electrolyte, enye ukuzinza kwe-electrolyte, kubandakanywa ukuzinza kwe-thermal, ukuzinza kweekhemikhali, ukuzinza kwe-voltage; okwesibini ukuzinza kunye nezinye izinto, ezifuna ukubunjwa kwefilimu ezinzileyo kunye ne-electrodes, akukho oxidation kunye ne-diaphragm, kwaye akukho ukubola kunye nomqokeleli wamanzi.
