Kushandiswa kweCMC Binder mumabhatiri

Munzvimbo yebhatiri tekinoroji, kusarudzwa kwebinder zvinhu kunoita basa rakakosha pakuona mashandiro, kugadzikana, uye hupenyu hurefu hwebhatiri.Carboxymethyl cellulose (CMC), polima inonyungudika nemvura yakabva muselulosi, yakabuda sechinhu chinovimbisa bhainda nekuda kwehunhu hwayo hunoshamisa hwakadai sesimba rekunamatira, kugona kugadzira firimu rakanaka, uye kuenderana kwezvakatipoteredza.

Kuwedzera kuri kuda kwemabhatiri ekushanda kwepamusoro mumaindasitiri akasiyana siyana, anosanganisira mota, zvemagetsi, uye simba rinogoneka, kwakurudzira kuedza kwakawanda kwekutsvagisa kugadzira zvinhu zvitsva zvebhatiri uye matekinoroji. Pakati pezvinhu zvakakosha zvebhatiri, binder inobata basa rakakosha mukumisa zvinhu zvinoshanda pamuunganidzi wazvino, kuve nechokwadi chekuchaja kwakanaka uye kuburitsa. Masungiro echinyakare akadai se polyvinylidene fluoride (PVDF) ane zvipimo maererano nekukanganisa kwezvakatipoteredza, zvivakwa zvemuchina, uye kuenderana neanotevera-chizvarwa bhatiri chemistries. Carboxymethyl cellulose (CMC), ine zvimiro zvayo zvakasiyana, yabuda seimwe inovimbisa imwe binder zvinhu zvekuvandudza kushanda kwebhatiri uye kusimba.

1.Zvinhu zveCarboxymethyl Cellulose (CMC):
CMC imvura inonyungudika kubva kune cellulose, yakasikwa polymer yakawanda muchirimwa sero madziro. Kuburikidza nekuchinja kwemakemikari, mapoka e-carboxymethyl (-CH2COOH) anounzwa mumusana we cellulose, zvichiita kuti kunyungudika kunyungudika uye kuvandudzwa kwebasa. Zvimwe zvakakosha zvivakwa zveCMC zvinoenderana nekushandiswa kwayo mukati

(1) mabhatiri anosanganisira:

Yakakwira yekunamatira simba: CMC inoratidzira yakasimba yekunamira zvivakwa, ichiigonesa kusungira zvinobudirira zvinhu zvinoshanda kune yazvino yekuunganidza pamusoro, nekudaro inovandudza electrode kugadzikana.
Kugona kwakanaka kwekugadzira firimu: CMC inogona kuumba mayunifomu uye akaonda mafirimu pamagetsi emagetsi, kufambisa kuvharirwa kwezvinhu zvinoshanda uye kuwedzera kuwirirana kwe electrode-electrolyte.
Kugarisana kwezvakatipoteredza: Senge biodegradable uye isina-chepfu polymer inotorwa kubva kune inogona kudzokororwa masosi, CMC inopa mabhenefiti ezvakatipoteredza pamusoro pezvakasungirirwa zvinosungirirwa sePVDF.

2.Kushandiswa kweCMC Binder mumabhatiri:

(1) Kugadzirwa kweElectrode:

CMC inowanzoshandiswa sebhainda mukugadzira maelectrodes emakemikari akasiyana siyana ebhatiri, anosanganisira lithium-ion mabhatiri (LIBs), sodium-ion mabhatiri (SIBs), uye supercapacitors.
MuLIBs, CMC inovandudza kunamatira pakati pezvinhu zvinoshanda (semuenzaniso, lithium cobalt oxide, graphite) uye iye zvino muunganidzi (semuenzaniso, foil yemhangura), zvichiita kuti kuwedzeredzwa kwe electrode kutendeseka uye kuderedza delamination panguva yebhasikoro.
Saizvozvo, muSIBs, CMC-yakavakirwa maelectrode anoratidza kugadzikana kwakagadziridzwa uye kuita kwebhasikoro zvichienzaniswa nemagetsi ane akajairwa mabhandi.
Iko kugona kugadzira firimu reCMCinova nechokwadi chekuputira yunifomu yezvinhu zvinoshanda pane yazvino muunganidzi, kuderedza electrode porosity uye kunatsiridza ion yekufambisa kinetics.

(2) Kuvandudza Kuita:

Nepo CMC pachayo isiri conductive, kubatanidzwa kwayo mumagadzirirwo emagetsi emagetsi kunogona kuwedzera huwandu hwemagetsi emagetsi e electrode.
Matanho akadai sewedzero yezvekuwedzeredza (semuenzaniso, kabhoni nhema, graphene) padivi peCMC akashandiswa kudzikamisa impedance ine chekuita neCMC-based electrodes.
Hybrid binder masisitimu anosanganisa CMC ane conductive polymers kana kabhoni nanomaterials yakaratidza mhedzisiro inovimbisa mukuvandudza electrode conductivity pasina kupira ma mechanic properties.

3.Electrode Stability uye Cycling Performance:

CMC inoita basa rakakosha mukuchengetedza kugadzikana kwe electrode uye kudzivirira inoshandira zvinhu dhizaini kana agglomeration panguva yekuchovha bhasikoro.
Iko kuchinjika uye kunamatira kwakasimba kwakapihwa neCMC kunobatsira mukusimba kwemagetsi emagetsi emagetsi, kunyanya pasi pesimba rekushushikana kwemamiriro panguva yekuchaja-yekuburitsa.
iyo hydrophilic chimiro cheCMC inobatsira mukuchengetedza electrolyte mukati meiyo electrode chimiro, kuve nechokwadi chekufambisa kweiyoni uye kuderedza kugona kupera pamusoro pekufamba kwenguva refu bhasikoro.

4.Matambudziko uye Maonero Anouya:

Nepo kushandiswa kweCMC binder mumabhatiri kuchipa zvakakosha, matambudziko akati wandei nemikana yekuvandudza

(1) iripo:

Enhanced Conductivity: Imwe tsvakiridzo inodiwa kukwirisa conductivity yeCMC-based electrode, kungave kuburikidza nehunyanzvi hwekugadzira binder maumbirwo kana synergistic musanganiswa ane conductive additives.
Kuenderana neHigh-Energy Che

mamistries: Kushandiswa kweCMC mumakemistri ari kubuda mabhatiri ane simba rakanyanya density, senge lithium-sarufa uye lithium-air mabhatiri, zvinoda kunyatsotariswa kwekugadzikana kwayo uye kuita kwemagetsi.

(2) Scalability uye Mutengo-kubudirira:
Kugadzirwa kwemaindasitiri-chikero cheCMC-based electrode kunofanirwa kuve nehupfumi, zvichidikanwa nemutengo-unoshanda synthesis nzira uye scalable kugadzira maitiro.

(3) Kuchengetedza Kwezvakatipoteredza:
Nepo CMC ichipa mabhenefiti ezvakatipoteredza pane akajairwa mabhandi, kuedza kwekusimudzira kuenderera mberi, sekushandisa zvakadzokororwa cellulose masosi kana kugadzira biodegradable electrolyte, zvinotenderwa.

Carboxymethyl cellulose (CMC)inomiririra zvinhu zvakasiyana-siyana uye zvakagadzikana zvinosungirirwa zvine mukana wakakura wekusimudzira tekinoroji yebhatiri. Mubatanidzwa wayo wakasarudzika wesimba rekunamira, kugona kugadzira firimu, uye kuenderana kwezvakatipoteredza kunoita kuti ive sarudzo inoyevedza yekusimudzira kushanda kwe electrode uye kugadzikana mumhando dzakasiyana dzemabhatiri chemistries. Kuenderera mberi kwekutsvaga nekusimudzira kuedza kwakanangana nekugadzirisa CMC-based electrode formulations, kuvandudza conductivity, uye kugadzirisa matambudziko ekusagadzikana kuchagadzira nzira yekutorwa kwakapararira kweCMC mumabhatiri echizvarwa chinotevera, zvichibatsira mukusimudzira hunyanzvi hwesimba remagetsi.
