Mwenje yezuva yave chikamu chakakosha chezvivakwa zvemazuva ano zvemaguta, zvichipa mhinduro yemwenje isingakuvadzi nharaunda uye isingadhuri. Mwenje iyi inoshandisa mabhatiri akasiyana-siyana kuchengetedza simba rinotorwa nemagetsi ezuva masikati.
1. Marambi emumugwagwa ezuva anowanzo shandisa mabhatiri e-lithium iron phosphate:
Chii chinonzi lithium iron phosphate battery?
Bhatiri reLithium Iron phosphate imhando yebhatiri reLithium-ion rinoshandisa Lithium Iron phosphate (LiFePO4) se cathode material uye Kabhoni se anode material. Voltage yemasero rimwe chete i3.2V, uye voltage yekucheka kuchaja iri pakati pe3.6V ne3.65V. Panguva yekuchaja, maion eLithium anobuda kubva kuLithium Iron phosphate ofamba nepakati pe electrolyte kuenda ku Anode, achizvipinza mu carbon material. Panguva imwe chete, maerekitironi anoburitswa kubva mu cathode ofamba nepakati pe external circuit kuenda ku Anode kuchengetedza kuenzana kwe chemical reaction. Panguva yekubuda, maion eLithium anofamba kubva ku Anode kuenda ku Cathode kuburikidza ne electrolyte, nepo maerekitironi achifamba kubva ku Anode kuenda ku Cathode kuburikidza ne External circuit, zvichipa simba kunyika yekunze.
Bhatiri re lithium iron phosphate rine zvakanakira zvakawanda: kuwanda kwesimba, saizi shoma, kuchaja nekukurumidza, kugara kwenguva refu, uye kugadzikana kwakanaka. Zvisinei, ndiro rinodhura zvakanyanya pakati pemabhatiri ese. Rinowanzo tsigira kuchaja kwe1500-2000 deep cycle uye rinogona kugara kwemakore 8-10 kana richishandiswa zvakajairika. Rinoshanda mukati mekupisa kwakakura kubva -40°C kusvika 70°C.
2. Mabhatiri eColloidal anowanzo shandiswa mumwenje yemagetsi ezuva:
Chii chinonzi bhatiri re colloidal?
Bhatiri recolloidal imhando yebhatiri rine lead-acid umo chinhu chinoiswa mujelling chinowedzerwa kusulfuric acid, zvichishandura electrolyte kuita segel. Mabhatiri aya, ane electrolyte yavo ine gelled, anonzi mabhatiri ecolloidal. Kusiyana nemabhatiri ekare ane lead-acid, mabhatiri ecolloidal anovandudza hunhu hwe electrochemical hwe electrolyte base structure.
Mabhatiri eColloidal haana kugadziriswa, zvichikunda matambudziko ekugadzirisa anowanzo sangana nemabhatiri ane lead-acid. Maumbirwo awo emukati anotsiva liquid sulfuric acid electrolyte ne gelled version, zvichiwedzera zvakanyanya kuchengetedza simba, kugona kuburitsa, kushanda kwekuchengetedza, uye hupenyu, dzimwe nguva zvichitopfuura mabhatiri e ternary lithium-ion pamutengo. Mabhatiri eColloidal anogona kushanda mukati mekupisa kwe -40°C kusvika 65°C, zvichiita kuti akwanise kushandiswa munzvimbo dzinotonhora. Anodzivirirawo kuvhunduka uye anogona kushandiswa zvakachengeteka mumamiriro akasiyana-siyana akaoma. Hupenyu hwawo hwekushanda huviri kana kupfuura kana tichienzanisa nemabhatiri akajairwa e lead-acid.
3. Mabhatiri eNMC lithium-ion anowanzo shandiswa mumwenje yemagetsi ezuva:
Mabhatiri eNMC lithium-ion ane mabhenefiti akawanda: simba rakawanda, saizi diki, uye kuchaja nekukurumidza. Anowanzo tsigira kuchaja kwe500-800 deep cycle, ane hupenyu hwakafanana nemabhatiri ecolloidal. Tembiricha yawo inoshanda iri -15°C kusvika 45°C. Zvisinei, mabhatiri eNMC lithium-ion anewo matambudziko, kusanganisira kugadzikana kwemukati kushoma. Kana akagadzirwa nevagadziri vasina kukodzera, pane njodzi yekuputika panguva yekuchaja zvakanyanya kana munzvimbo dzinopisa zvakanyanya.
4. Mabhatiri ane lead-acid anowanzo shandiswa mumwenje yemagetsi ezuva:
Mabhatiri e lead-acid ane ma electrode anoumbwa ne lead ne lead oxide, ane electrolyte yakagadzirwa ne sulfuric acid solution. Zvakanakira zvikuru zvemabhatiri e lead-acid ivoltage yavo yakagadzikana uye mutengo wakaderera. Zvisinei, ane simba rakaderera, zvichikonzera huwandu hwakawanda kana tichienzanisa nemamwe mabhatiri. Hupenyu hwavo hupfupi, hunowanzo tsigira 300-500 deep cycle charges, uye anoda kugadziriswa nguva nenguva. Pasinei nekushata uku, mabhatiri e lead-acid achiri kushandiswa zvakanyanya muindasitiri yemagetsi emumugwagwa ezuva nekuda kwemutengo wawo.
Kusarudzwa kwemabhatiri emagetsi emumugwagwa anoshandiswa nesolar kunoenderana nezvinhu zvakaita sekushandisa simba zvakanaka, hupenyu hwezuva, zvinodiwa pakugadzirisa, uye mutengo. Rudzi rwebhatiri rumwe nerumwe rune zvarunobatsira zvakasiyana, zvichienderana nezvinodiwa nemamiriro ezvinhu akasiyana, zvichiita kuti mwenje yemumugwagwa irambe iri mhinduro yemwenje yakavimbika uye inogara kwenguva refu.
