Ukusetyenziswa kweSodium Carboxymethyl Cellulose kwiBattery yeSekondari ye-Electrolyte engenamanzi

I-Sodium carboxymethyl cellulose (i-NaCMC) yi-polymer enyibilikayo emanzini, ubunzima bemolekyuli ephezulu ephuma kwi-cellulose. Iimpawu zayo eziyingqayizivele, ezifana nokugcinwa kwamanzi aphezulu, ikhono elihle kakhulu lokwenza ifilimu, kunye nokuzinza okulungileyo, kwenza ukuba kube yinto ebalulekileyo kwizicelo ezininzi zezoshishino. Kwiminyaka yakutshanje, i-NaCMC iye yavela njengomviwa othembisayo wokusetyenziswa kwiibhetri zesibini ze-electrolyte ezingenamanzi ngenxa yokukwazi ukuphucula ukusebenza kwebhetri kunye nokhuseleko. Kweli nqaku, siza kuxubusha ukusetyenziswa kwe-NaCMC kwiibhetri zesibini ze-electrolyte ezingenamanzi.

Iibhetri zesibini ze-electrolyte ezingenamanzi zisetyenziswa ngokubanzi kwizixhobo zombane eziphathwayo, izithuthi zombane, kunye neenkqubo zokugcina amandla ngenxa yobuninzi bamandla kunye nobomi bomjikelo omde. Nangona kunjalo, ukusetyenziswa kwe-electrolyte engekho emanzini kubangela iingxaki zokhuseleko, ezifana nokungazinzi kwe-thermal, ukutsha kunye nokuvuza. I-NaCMC iboniswe ukujongana nale miba ngokuphucula ukhuseleko kunye nokusebenza kweebhetri zesibini ze-electrolyte ezingenamanzi.

1. Ukuzinza kwe-Electrolyte: Ukuzinza kwe-electrolyte kubalulekile ekusebenzeni kunye nokhuseleko lwebhetri. I-NaCMC inokuphucula ukuzinza kwe-electrolyte ngokunciphisa izinga lokuphuma kwamanzi, ukuthintela ukuvuza, kunye nokwandisa i-viscosity ye-electrolyte. Ukongezwa kwe-NaCMC kunokunciphisa ukubola kwe-electrolyte kunye nokwandisa ukuzinza kwayo kwe-thermal.
2. Ion conduction: I-NaCMC inokuphucula i-ion conduction ye-electrolyte ngokwenza inethiwekhi efana ne-gel eyenza ukuthuthwa kwee-ion ze-lithium phakathi kwe-electrodes. Oku kukhokelela ekusebenzeni okuphuculweyo kwebhetri kunye nobomi bomjikelezo omde.
3. Ukhuseleko lwebhetri: I-NaCMC inokuphucula ukhuseleko lwebhetri ngokuthintela ukubunjwa kwee-dendrites, eziyizakhiwo ezifana nenaliti ezinokukhula ukusuka kumphezulu we-anode kwaye zingene kwi-separator, ekhokelela ekujikelezeni okufutshane kunye nokubaleka kwe-thermal. I-NaCMC inokuphucula ukuzinza komatshini we-electrode kwaye ithintele i-detachment yayo kumqokeleli wangoku, ukunciphisa umngcipheko weesekethe ezimfutshane zangaphakathi.
4. Ukuzinza kwe-Electrode: I-NaCMC inokuphucula ukuzinza kwe-electrode ngokwenza i-coating efanayo kwindawo yayo, enokuthintela ukuchithwa kwezinto ezisebenzayo kunye nokunciphisa ukulahlekelwa kwamandla ngexesha. I-NaCMC inokuphucula ukunamathela kwe-electrode kumqokeleli wangoku, ekhokelela ekuphuculeni ukuhanjiswa kunye nokunciphisa ukuxhathisa.

Ukuqukumbela, i-NaCMC sisongezo esithembisayo sokusetyenziswa kwiibhetri zesibini ze-electrolyte ezingenamanzi ngenxa yokukwazi ukuphucula ukusebenza kwebhetri kunye nokhuseleko. Iimpawu zayo ezikhethekileyo, ezifana nokugcinwa kwamanzi aphezulu, ubuchule obuhle bokuqulunqa ifilimu, kunye nokuzinza okulungileyo, kwenza ukuba ibe yinto eyongezelelweyo yokuphucula ukuzinza kunye ne-ion conduction ye-electrolyte, ukukhusela ukubunjwa kwe-dendrites, ukuphucula ukuzinza komatshini we-electrode, kunye nokunciphisa ukulahleka kwamandla ngokuhamba kwexesha. Ukusetyenziswa kwe-NaCMC kunokukhokelela ekuphuhlisweni kweebhetri zesibini ze-electrolyte ezikhuselekileyo nezisebenzayo, ezinokuthi zibe nempembelelo enkulu ekuphuhlisweni kweshishini lezithuthi zombane kunye necandelo lokugcina amandla.
