Kushandiswa kweCMC Binder mumabhatiri

Mudenga reTekinoroji yebattery, sarudzo yezvinhu zvekusungwa zvinotaridza chiitiko chakakosha pakufunga kuita, kugadzikana, uye kuzere kwebhatiri.Carboxymethyl cellose (cmc), Polymer-Soluble Polymer anotorwa kubva kuCellulose, akaburitswa seyekuvimbisa binder nekuda kwezvinhu zvakasarudzika zvakadai sesimba rakanyanya kusimba, kugona kwemafirimu ekuumba, uye kuenderana kwezvakatipoteredza.

Kuwedzera Kuwedzera Kwemapamusoro-maitiro ekuita maindasitiri akasiyana-siyana, kusanganisira zvemotokari, zvemagetsi, uye simba rakatsvuka, rakakurudzira kuedza kwakawanda kwekunyatsogadzira mabheti ebhatiri uye matekinoroji. Pakati pezvikamu zvakakosha zvebhatiri, iyo Binder inoita basa rakakosha mukuzvisimbisa zvinoshanda mumuteresi aripo, anoverengera mari yekubhadhara uye anodzora maClound. Zvechivanhu zvechinyakare sePolyvinylidene Fluoride (PVDF) zvine zvazviparadzaniswa zvezvemamiriro ekunze, uye kuwirirana neyekutanga-kwechizvarwa bhatiri emistries. Carboxymethyl Cellelose (CMC), ine zvivakwa zvaro zvakasarudzika, zvakabuda semhando yekuvimbisa imwe yekubatanidza zvinhu zvekuvandudza mabasa ebhatiri uye kusimbisa.

1.Properties yeCarboxyMethyl Cellulose (CMC):
CMC imvura-solullo inobva kune cellulose, polymer yakasikwa yakawanda mumasango masero emadziro. Kuburikidza nemakemikari kugadziridzwa, carboxymethyl mapoka (-Ch2cooh) anounzwa muCellulose Backbone, zvichikonzera kusimba kwekusimbisa uye kwakagadziridzwa mashandiro ekushanda. Zvimwe zvakakosha zvivakwa zveCMC zvinoenderana nekunyorera kwayo mukati

(1) mabhatiri anosanganisira:

Yakanyanya Dhiziri Simba Resimba: CMC Inoratidza Zvakasimba Zvivakwa, zvichivaita kuti zvive zvinobudirira zvinosunga zvinoshanda zvinoshanda kune iyo yazvino muteresi, nekuvandudza magetsi emagetsi kugadzikana.
Good Firimu-Kugadzira Kugona: CMC inogona kuumba yunifomu uye yakajeka mafirimu pane electrode nzvimbo, kufambisa iyo yekuvhara yezvishandiso zvinoshanda uye kuvandudza electrode-Electrolyte kudyidzana.
Kuenderana Kwepomberedza: Sekuratidzira kweBiodetable uye isina chepfu yakabviswa kubva kune yekuvandudza zvinyorwa, CMC inopa zvakanakira zvakatipoteredza pamusoro peSynthetic Binders sePVDF.

2.Application yeCMC Binder muBatteries:

(1) Electrode Fibraction:

CMC inowanzo shandiswa seyekuchinjika mukugadzira ma electrodes yemakemikari akasiyana-siyana, kusanganisira lithium-ion mabhatiri (sodium-ion mabhatiri (SIBS), uye masheji makuru.
MuLibs, CMC inovandudza kudenha pakati pezvinyorwa zvinoshanda (semuenzaniso, lithium coilt oxide, graphist) uye iyo yemuteresi (eg, inotungamira kuvimbika kweElectrode kutendeka uye kudzikisira kwekunyora panguva yekucheka.
Saizvozvo, muBibs, CMC-yakavakirwa magetsi inoratidza kuvandudzwa kwakasimba uye cycling performance zvichienzaniswa nemagetsi nemagetsi zvinosungirwa.
Iyo firimu-inogadzira kugona kweCmcInovimbisa yunifomu yekuvhara yezvinhu zvinoshanda pane yazvino muteresi, kuderedza emagetsi emagetsi uye kugadzirisa ion kutakura kinetics.

(2) Kuverengera Kuwedzera:

Nepo CMC pachayo isiri yekufambisa, iko kubatanidzwa kwayo kuita electrode mafomu kunogona kusimudzira magetsi ese ekuita kweale electrode.
Nzira dzakadai sekuwedzera kwekuzvibata (semuenzaniso, kabhoni dema, Grapheene) parutivi rweCMC dzakashanda kuderedza kusavapo kwakabatana neCMC-yakavakirwa magetsi.
Hybrid Binder Systems inosanganisira CMC nePolymers Polymers kana Carbon Nanomaterials yakaratidza kuvimbisa kunoguma nekuvandudza magetsi kusazviita pasina kubayira michero.

3.Elelelectrode kugadzikana uye cycling performance:

CMC inotora basa rakakosha mukuchengetedza electrode kugadzikana uye kudzivirira anoshanda zvinhu zvakasarudzika kana kuunganidzwa panguva yekukwira.
Kuchinjika uye kusimba kuDhinda kwakapihwa neCMC kunobatsira mukuvimbika kwemagetsi, kunyanya pasi pemamiriro ezvinhu ane simba panguva yekubhadhara-discharge clecle.
Iyo hydrophic mhando yeCMC inobatsira mukuchengetedza Electrolyte mukati meiyo Electrode chimiro, ichiita kuti isimbe ion yekutakura uye kuderedza kugona kwekufamba kwenguva refu.

4.CHALALENGES uye NZIRA YEKUSVIKI:

Ipo kushandiswa kweCMC kuchinjika mumabhatiri kunopa zvakakwanywa zvakanakira, matambudziko akati wandei nemikana yekuvandudza

(1) kuvapo:

Kuvandudzwa Kufambidzana: Kumwe kutsvagisa kunodiwa kuti uwedzere kunhuhwirira kweCMC-yakavakirwa magetsi, kungave kuburikidza nekusanganisa kwekugadzira kana kusanganisa kweSynergistic nemaitiro ekuzvibata.
Kuenderana neakakwira-simba che

Mistries: Iyo yekushandiswa kweCMC mukubuda kwebhatiri nemakomisheni ane simba rakakura, akadai lithium-sarulog-saruimu-mhepo mabhatiri ekugadzikana uye maitiro eElectrochemical.

(2) Scalability uye mutengo-kushanda:
Maindasitiri-kuunganidzwa kwemagetsi eCMC anofanirwa kuve ehupfumi anofanirwa kuve ehupfumi anoshanda, anokoshesa mari inobudirira synthesis nzira uye maitiro anowanikwa echigadzirwa.

(3) Kutsigirwa kwezvakatipoteredza:
Nepo Cmc inopa zvakanakira zvevanonchengetedzo pamusoro pematanda emamiriro ezvinhu, kuedza kusimudzira kwekutsigira mberi, sekushandisa zvinodzokorwazve mhuru mbozha kana kuvandudza maElekitori

Carboxymethyl cellose (cmc)Inomiririra zvinhu zvakasiyana uye zvinosemesa zvekusungwa zvine midziyo yakakura kwazvo yekufambira mberi kwebattery battery. Yayo yakasarudzika yekusanganisa kwesimba Kuenderera mberi kwekutsvaga nekuvandudza kuedza kwakanangana nekudzikisira kweCMC.
