Battery-giredhi CMC

Battery-giredhi carboxymethyl cellulose (CMC) imhando yakasarudzika yeCMC inoshandiswa sebhainda uye gobvu ajenti mukugadzira lithium-ion mabhatiri (LIBs). MALIB mabhatiri anochajwa anowanzo shandiswa mumidziyo yemagetsi inotakurika, mota dzemagetsi, uye masisitimu ekuchengetedza simba nekuda kwekuwanda kwesimba uye hupenyu hurefu hwekutenderera. Battery-giredhi CMC inoita basa rakakosha mukugadzirwa kwemagetsi eLIBs, kunyanya mukugadzirwa kwemaelectrodhi ezvese cathode uye anode.

Mabasa uye Zvivakwa zveBattery-Giredhi CMC:

1. Binder: Battery-giredhi CMC inoshanda sebhainda rinobatsira kubata anoshanda emagetsi emagetsi (se lithium cobalt oxide ye cathodes uye graphite ye anode) pamwe chete uye anonamatira kune yazvino yekuunganidza substrate (kazhinji aluminium foil yema cathodes uye foil yemhangura yeanode. ) Izvi zvinovimbisa kunaka kwemagetsi conductivity uye mechanical kugadzikana kwe electrode.
2. Thickening Agent: Bhatiri-giredhi CMC inoshandawo seyakakora mumiriri mune electrode slurry kuumbwa. Inobatsira kudzora viscosity uye rheological zvimiro zve slurry, zvichibvumira kupfekedza yunifomu uye kuiswa kweiyo electrode zvinhu pane yazvino muunganidzi. Izvi zvinogonesa kuenderana kwe electrode ukobvu uye density, izvo zvakakosha kuti uwane yakakwana bhatiri kuita.
3. Ionic Conductivity: Bhatiri-giredhi CMC inogona kunyatso gadziridzwa kana kuumbwa kuti iwedzere yayo ionic conductivity mukati mebhatiri electrolyte. Izvi zvinogona kuvandudza kushanda kwese electrochemical uye kugona kwe lithium-ion bhatiri.
4. Electrochemical Stability: Battery-giredhi CMC yakagadzirirwa kuchengetedza kuvimbika kwayo kwechimiro uye electrochemical kugadzikana pamusoro pehupenyu hwebhatiri, kunyangwe pasi pemamiriro ekushanda akaomarara sekupisa kwakanyanya uye mitengo yebhasikoro. Izvi zvinovimbisa kuvimbika kwenguva refu uye kuchengetedzwa kwebhatiri.

Manufacturing Process:

Battery-giredhi CMC inowanzo gadzirwa kuburikidza nekemikari gadziriso ye cellulose, yakasikwa polysaccharide inotorwa kubva kumiti fibers. Mapoka ecarboxymethyl (-CH2COOH) anounzwa pane cellulose musana kuburikidza neakatevedzana emakemikari reactions, zvichikonzera kuumbwa kwecarboxymethyl cellulose. Iyo dhigirii yecarboxymethyl substitution uye molecular huremu hweCMC inogona kugadzirwa kuti isangane nezvinodiwa chaizvo zve lithium-ion bhatiri application.

Applications:

Bhatiri-giredhi CMC inonyanya kushandiswa mukugadzira maelectrode emabhatiri e-lithium-ion, kusanganisira ese ari maviri cylindrical uye pouch cell masisitimu. Inosanganiswa mu electrode slurry formulation pamwe chete nezvimwe zvikamu zvakadai sekushanda kwe electrode zvinhu, conductive additives, uye solvents. Iyo electrode slurry inozoputirwa pane yazvino yekuunganidza substrate, yakaomeswa, uye inounganidzwa musero rekupedzisira rebhatiri.

Zvakanakira:

1. Yakavandudzwa Electrode Performance: Bhatiri-giredhi CMC inobatsira kusimudzira mashandiro e electrochemical, kugadzikana kwebhasikoro, uye chiyero kugona kwemabhatiri e-lithium-ion nekuita kuti yunifomu ye electrode ipfeke uye kunamatira kwakasimba pakati pezvinhu zvinoshanda uye vateresi vemazuva ano.
2. Kuwedzeredzwa Kuchengetedzeka uye Kuvimbika: Kushandiswa kweyemhando yepamusoro bhatiri-giredhi CMC ine yakarongedzerwa zvivakwa kunobatsira kuchengetedzeka, kuvimbika, uye hupenyu hurefu hwemabhatiri e-lithium-ion, kuderedza njodzi ye electrode delamination, mapfupi maseketi, uye kupisa kunotiza zviitiko.
3. Tailored Formulations: Bhatiri-giredhi CMC magadzirirwo anogona kugadzirwa kuti asangane nezvinodiwa chaizvo uye mashandiro ezvinangwa zveakasiyana bhatiri chemist, maapplication, uye maitiro ekugadzira.

Muchidimbu, bhatiri-giredhi carboxymethyl cellulose (CMC) chinhu chakasarudzika chinoita basa rakakosha mukugadzirwa kwemabhatiri e-high-performance lithium-ion. Hunhu hwayo hwakasiyana-siyana sebhainda uye gobvu mumiriri inobatsira kugadzikana, kushanda zvakanaka, uye kuchengetedzeka kwelithium-ion bhatiri maelectrodes, zvichiita kuti kufambira mberi kwehunyanzvi hwesimba remagetsi uye kufamba kwemagetsi.
