Withkuenderera mberi kwekuvandudzwa kwemotokari itsva dzesimba, kutarisisa kwakanyanya kwakabhadharwa kune mabhatiri emagetsi.Bhatiri, mota uye yemagetsi control system ndiwo matatu akakosha emagetsi emagetsi matsva, ayo bhatiri remagetsi ndiro chikamu chakakosha, chinogona kunzi "moyo" wemotokari nyowani, saka ndeapi mabhatiri emagetsi matsva. mota dzemagetsi? Zvakadini nemapoka makuru?
1. Lead-asidhi bhatiri
Lead-acid bhatiri (VRLA) ibhatiri rine maelectrodes anonyanya kugadzirwa nemutobvu nemaokisisa ayo, uye electrolyte isulfuric acid solution.Mumamiriro ekupomerwa kwebheteri ye-lead-acid, chikamu chikuru che electrode yakanaka inotungamirira diokisi, uye chikamu chikuru che electrode yakaipa inotungamira; muhurumende yakasunungurwa, chikamu chikuru chezvakanaka uye zvisina kunaka electrodes is lead sulfate.Iro zita remagetsi ebhatiri re-sero-lead-asidi bhatiri i2.0V, inogona kuburitswa kusvika pa1.5V nekuchajwa.kusvika ku2.4V; mumashandisirwo, 6 mabhatiri e-single-cell lead-acid anowanzobatanidzwa munhevedzano kuti aite zita rekuti 12V lead-acid bhatiri , uye 24V, 36V, 48V, nezvimwewo.
Se tekinoroji yakura, mabhatiri e-lead-asidhi achiri iwo ega bhatiri remotokari dzemagetsi dzinogona kugadzirwa-zhinji nekuda kwemutengo wadzo wakaderera uye chiyero chepamusoro chekuburitsa.Nekudaro, iyo chaiyo simba, chaiyo simba uye simba density yemabhatiri e-lead-asidhi yakadzikira, uye mota dzemagetsi dzinoshandisa izvi sesosi yemagetsi hadzigone kuve nekumhanya kwakanaka uye kufamba.range .
2. Nickel-cadmium mabhatiri uye nickel-metal hydride mabhatiri
Nickel-cadmium bhatiri (Nickel-cadmium bhatiri, rinowanzonzi NiCd, rinodaidzwa kuti “nye-cad”) bhatiri rine mukurumbira.Bhatiri iri rinoshandisa nickel hydroxide (NiOH) nesimbi cadmium (Cd) semakemikari kugadzira magetsi.Kunyange zvazvo kushanda kwayo kuri nani kudarika kwemabhatiri e-lead-acid, ine simbi inorema, iyo inosvibisa nharaunda mushure mekushandiswa nekusiiwa.
Iyo nickel-cadmium bhatiri inogona kuchajwa uye kuburitswa kanopfuura ka500, iyo ine mari uye yakasimba.Kupikisa kwayo kwemukati kudiki, kupikisa kwemukati kudiki, kunogona kukurumidza kuchaja, uye inogona kupa yakakura ikozvino kune mutoro, uye shanduko yemagetsi idiki panguva yekubuda, inova yakanaka kwazvo DC magetsi emagetsi bhatiri.Kuenzaniswa nemamwe marudzi emabhatiri, nickel-cadmium mabhatiri anogona kutsungirira kuwandisa kana kuwandisa.
Ni-MH bhatiri inoumbwa nehydrogen ion uye simbi nickel, uye simba rayo rekuchengetedza i30% kupfuura iro reNi-Cd bhatiri. .
3. Lithium bhatiri
Lithium bhatiri imhando yebhatiri inoshandisa lithium simbi kana lithium alloy seyakanaka electrode zvinhu uye inoshandisa isiri-aqueous electrolyte mhinduro.Lithium mabhatiri anogona kukamurwa kuita zvikamu zviviri: lithium simbi mabhatiri uye lithium ion mabhatiri..Lithium-ion mabhatiri haana lithium mune simbi yesimbi uye anochajwa zvakare.
Lithium simbi mabhatiri anowanzo shandisa manganese dioxide seyakanaka electrode zvinhu, simbi lithium kana alloy simbi yayo seyakaipa electrode zvinhu, uye kushandisa isiri-aqueous electrolyte mhinduro.Lithium bhatiri zvinhu zvinonyanya kuumbwa ne: positive electrode material, negative electrode material, separator, electrolyte.
Pakati pezvinhu zvecathode, zvinowanzoshandiswa zvinhu zvinonzi lithium cobalt oxide, lithium manganate, lithium iron phosphate uye ternary zvinhu (polymers nickel, cobalt uye manganese).Iyo yakanaka electrode zvinhu inotora chikamu chikuru (huwandu hwehuwandu hwezvakanaka uye zvisina kunaka electrode zvinhu ndeye 3: 1 ~ 4: 1), nokuti kushanda kweiyo yakanaka electrode zvinhu zvinokanganisa zvakananga kushanda kwe lithium-ion bhatiri, uye mutengo wayo. zvakare inosarudza zvakananga mutengo webhatiri.
Pakati pezvinhu zveanode, izvo zvazvino anode zvinhu zvinonyanya kugadzirwa graphite uye yekugadzira graphite.Zvishandiso zveanode zviri kuongororwa zvinosanganisira nitrides, PAS, tin-based oxides, tin alloys, nano anode materials, uye mamwe macommunication intermetallic.Sechimwe chezvikamu zvina zvikuru zvelithium bhatiri, iyo negative electrode material inoita basa rakakosha mukuvandudza kugona uye kutenderera kuita kwebhatiri, uye ndicho chinongedzo chepakati pakati peiyo lithium bhatiri indasitiri.
Sero yemafuta isiri-yakapisa electrochemical simba rekushandura mudziyo.Iyo kemikari simba rehydrogen (nemamwe mafuta) uye oxygen inoramba ichishandurwa kuita simba remagetsi.Nheyo yekushanda kwayo ndeyokuti H2 yakasvibiswa muH + uye e- pasi pekuita kweanode catalyst, H + inosvika kune electrode yakanaka kuburikidza neproton exchange membrane, inopindirana neO2 pa cathode kuti ibudise mvura, uye inosvika kune cathode kuburikidza ne rekunze redunhu, uye inoenderera ichiita inoburitsa ikozvino. Kunyangwe sero remafuta rine izwi rekuti "bhatiri", haisi simba rekuchengetedzamudziyo nenzira yechinyakare, asi mudziyo wekugadzira magetsi. Uyu ndiwo musiyano mukuru pakati pefuel cell nebhatiri rechinyakare.
