bhatiri reGraphite rakanzwainoita basa guru mumatekinoroji emazuva ano emabhatiri, kunyanya mumabhatiri anoyerera uye masero emafuta. Sechinhu chinoshanda uye chinogara kwenguva refu, girafiti yegrafiti inopa kufambiswa kwemagetsi kwakanaka uye kugadzikana kwekupisa, ukuwo ichibatsirawo mukuvandudza mashandiro ebhatiri, kureba kwenguva yehupenyu, uye kuchengetedzeka kwakawedzerwa. Mukushandiswa kwemabhatiri anoyerera uye masero emafuta, hunhu hwakasiyana hwegirafiti yegrafiti inoita kuti ive chinhu chakakosha muhurongwa hwekuchengetera simba hunoshanda zvakanyanya.
Kushandiswa kweGraphite Battery Felt muFlow Batteries
Mabhatiri ekuyerera, kunyanya mabhatiri ekuyerera evanadium redox (VRFB) uye mabhatiri ekuyerera ezinc-bromine, anotsvakurudzwa zvakanyanya uye anoshandiswa muhunyanzvi hwekuchengetedza simba. Anochengeta uye anoburitsa simba kuburikidza nezvinhu zvinoshanda zvakanyungudutswa mu electrolyte, izvo zvinoapa hupenyu hurefu uye kugona kukuru kwekuchengetedza simba zvichienzaniswa nemabhatiri echinyakare. Mukugadzirwa kwemabhatiri aya, graphite battery felt inowanzo shandiswa muzvikamu zve electrode, kunyanya apo electrolyte inoyerera inosangana nezvinhu zve electrode.
Kufambiswa kwemafuta egraphite kwakanyanya ndiyo mukana mukuru wekushandiswa kwayo mumabhatiri ekuyerera. Mumabhatiri ekuyerera, electrochemical reaction inoitika pakati peelectrolyte nemaelectrodes, saka kufambisa mafuta eelectrode kwakakosha pakushanda kwebhatiri. Sechinhu cheelectrode, graphite felt inogona kukurudzira kufamba kwemaion mu electrolyte uye kuona kuti maerekitironi anofambiswa zvakanaka, izvo zvinovandudza kushaja kwebhatiri uye kushanda zvakanaka kwekuburitsa mafuta.
Pamusoro pezvo, graphite felt inoita basa guru mukutarisira kupisa mukati memabhatiri ekuyerera. Munguva yekushanda kwemabhatiri ekuyerera, kupisa kwemukati kunogadzirwa. Kufambiswa kwakanaka kwekupisa kwegraphite felt kunobatsira kubvisa kupisa uku, kudzivirira kupisa kwebhatiri uye kuona kuti rinoshanda mukati mehurefu hwekupisa hwakakwana. Kugona uku kwekutarisira kupisa hakungobatsiri chete kuwedzera hupenyu hwebhatiri asiwo kunowedzera kuchengetedzeka kwaro, zvichideredza njodzi yekukundikana kwebhatiri nekuda kwekupisa kwakanyanya.
Kushandiswa kweGraphite Battery Felt muFuel Cells
Masero emafuta zvishandiso zvinoshandura simba remakemikari kuita simba remagetsi kuburikidza nemagetsi, zvinoshandiswa zvakanyanya mumotokari dzemagetsi, simba rekuchengetedza, uye masisitimu esimba rinodzokororwa. Kushandiswa kwebhatiri regirafiti rinonzwa mumasero emafuta kunonyanya kukosha mubasa raro segasi rinopararira (GDL) uye electrode material. Kukosha kwaro kunoonekwa zvakanyanya mumasero emafuta eproton exchange membrane (PEMFC).
Muma fuel cells, graphite felt inoshanda se gas diffusion layer (GDL), inotarisira kugovera zvakaenzana ma reactant gases akadai sehydrogen ne oxygen kunzvimbo dze electrode, ukuwo ichishanda se conductive medium. Nekuda kwe conductivity yayo yakanaka, graphite felt inogona kutamisa ma electrons anogadzirwa mukati me cell kuenda ku external circuit, zvichiita kuti simba remagetsi ribude. Maumbirwo ayo ane maburi anobatsirawo kupararira kwe gas uye electrolyte conduction, zvichiita kuti electrochemical reactions mu fuel cells ifambe zvakanaka.
Graphite inonzwikwa mumafuel cells haingodi chete kupa magetsi akanaka, asi inofanirawo kuva nekudzivirira ngura zvakanaka uye kushanda zvakanaka pakupisa kwakanyanya. Sezvo mafuel cells achishanda munzvimbo dzine kupisa kwakanyanya uye dzinopisa, kugadzikana kwemakemikari uye kugadzikana kwekupisa kwegraphite zvinoita kuti ive sarudzo yakanaka. Inogona kushanda zvakadzikama mumamiriro ezvinhu akaipisisa kwenguva yakareba, ichidzivirira kuora kwekushanda nekuda kwekukwegura kwezvinhu kana ngura.
Uyezve, graphite inonzwikwa mumafuel cells inobatsirawo kugadzirisa mashandiro ekuita basa kuburikidza nechimiro chayo chakagadzirwa zvakanaka. Kurongeka uye kuiswa kwema graphite fibers hakungowedzere simba rayo chete asiwo kunovandudza mashandiro egasi. Nekugadzirisa nemazvo porosity uye chimiro chegraphite felt, simba rekubuda uye mashandiro emafuel cells zvinogona kuvandudzwa zvakanyanya.
Kuvandudzwa Kwemangwana kweGraphite Battery Felt
Sezvo matekinoroji ebhatiri rinoyerera uye maseru emafuta achiramba achichinja, mikana yekushandisa bhatiri regrafiti iri kuwedzera. Vaongorori vari kutsvaga nzira dzekuwedzera mashandiro ebhatiri regrafiti kuburikidza nekushandisa graphite composites, matekiniki edoping, uye kurapwa kwepamusoro. Semuenzaniso, kuvandudza dhizaini yemagadzirirwo ebhatiri regrafiti kunogona kuwedzera conductivity yayo, kuwedzera kuramba kwayo ngura, uye kuvandudza kugona kwekutonga kupisa. Kuvandudzwa uku kuchawedzera kufambira mberi kwekushandiswa kwemabhatiri anoyerera uye maseru emafuta munzvimbo dzekuchengetedza simba dzinoshanda zvakanyanya uye nzvimbo dzekushandura.
Mukupedzisa, kushandiswa kwebhatiri regrafiti rinonzwa mumabhatiri anoyerera uye mafeteri emafuta, nekufambisa kwayo zvakanaka, kugona kwayo kutonga kupisa, uye kugadzikana kwechimiro, kwave chinhu chakakosha kune aya masisitimu ekuchengetedza simba epamusoro uye ekushandura. Sezvo matekinoroji esimba achiramba achikura, bhatiri regrafiti rinonzwa richaita basa rakakosha mukusimudzira hunyanzvi hwetekinoroji yemabhatiri, kuvandudza mashandiro esimba, uye kusimudzira budiriro inoenderera mberi.
