Kuyerera mabhatiri anowana 70-85% kunyatsoshanda zvinoenderana nekemikari uye mamiriro ekushanda. Kubudirira kunokanganisa zvakananga mihoro yepurojekiti-hurongwa hwekuchovha bhasikoro zuva nezuva ne 85% kunyatsoita zvichienzaniswa ne75% kushanda zvakanaka kunopa 15% yakawanda inotengeswa simba pagore, zvichikanganisa zvakanyanya kudzoka pamusoro pemakore gumi ehupenyu hweprojekiti.
Inguva yakareba sei mabhatiri egridi anochengetedza kushanda asati atsiviwa?
Lithium-ion masisitimu anowanzoita 5,000-7,000 macycles asati adzikisira pasi pe80% inokwana, zvichiturikira kusvika 10-15 years pasi pekuchovha bhasikoro zuva nezuva. Mabhatiri anoyerera anoda gumi,{8}} ma cycles anogona kugonesa 20+ kushanda kwegore, kunyange hazvo magadzirirwo mashoma akasimbisa mafungidziro aya kwenguva refu. Huwandu hwekudzikisirwa hunowedzera nekudzika kwakadzika, tembiricha yakakwira, uye kugara uchichaja, zvichiita kusawirirana pakati pekuwedzera mari yazvino uye kuchengetedza kukosha kweasset kwenguva refu. Mapurojekiti mazhinji anosanganisira ekuwedzera mabhajeti ekuwedzera kwehuwandu hwehuwandu hwekuwedzera sezvo mabhatiri ekutanga anoderera.
Imhando ipi yebhatiri ine njodzi yakaderera yemoto?
Mabhatiri anoyerera anoshandisa mvura{{0}eelectrolyte anopa njodzi shoma nekuda kwe-kemesitiri isingabatike uye kuparadzaniswa kwemagetsi kubva pakuchengetera magetsi. Sodium-mabhatiri eion ane njodzi yakaderera yekumhanya kupfuura lithiamu-ion kuburikidza nekemikari yakagadzikana uye kuderera kwesimba. Pakati pelithium chemistries, LFP akasiyana akachengeteka zvakanyanya kupfuura mabhatiri eNMC, ane kugadzirwa kwakadzikama kwekupisa uye maitiro akatsiga ekupisa. Lead{{7}mabhatiri easidhi anogona kugadzira gasi rehydrogen rinobvira moto panguva yekuchaja, zvinoda kufefeterwa nemhepo uye zvidzori zvinopinza. Yakakodzera bhatiri manejimendi masisitimu, yekudziya yekutarisa, uye yekudzikira moto midziyo inoderedza njodzi pamatekinoroji ese, asi misiyano yemakemikari inoumba zvakakosha kuchengetedzwa.
Mabhatiri esodium-ion agadzirira kutsiva lithium-ion mumashandisirwo egridi?
Mabhatiri eSodium-ion anowanikwa mune zvekutengesa kugedhi bhatiri rekuchengetedza simba rekushandisa kubva muna 2024, nekuisa kuChina uye kutanga kushandiswa kweUS. Mukana wokushanda unoramba uripo-150 Wh/kg simba remagetsi richipesana ne lithium-ion's 185-265 Wh/kg, uye kusimbiswa kweupenyu kuchiri kuwanda nedata shoma{13}}refu rekushanda.
