Kuchengetedzwa kwemabhatiri e-lithium uye mabhatiri e-lead-acid yakagara iri nyaya yekukakavadzana pakati pevashandisi.Vamwe vanhu vanoti mabhatiri e-lithium akachengeteka kupfuura mabhatiri e-lead-acid, asi vamwe vanofunga zvakasiyana.Kubva pamaonero ehurongwa hwebhatiri, ikozvino lithium bhatiri packs anonyanya 18650 mabhatiri ekurongedza, uye lead-asidhi mabhatiri anonyanya kugadzirisa-isina lead-asidhi mabhatiri ane kuita chisimbiso kwakanaka, uye njodzi dzezviviri zvakangofanana.Ndiani akachengeteka, ingotarisa pasi uye iwe uchaziva!

lithium bhatiri:

Lithium mabhatiri imhando yemabhatiri anoshandisa lithium simbi kana lithium alloy sechinhu chisina kunaka che electrode uye anoshandisa isiri-aqueous electrolyte solution.Lithium mabhatiri anogona kukamurwa kuita zvikamu zviviri: lithium simbi mabhatiri uye lithium-ion mabhatiri.Muna 1912, lithium simbi mabhatiri akatanga kutaurwa uye kudzidza naGilbert N. Lewis.Nekuda kweiyo inoshanda makemikari zvimiro zvelithium simbi, kugadzirisa, kuchengetedza, uye kushandiswa kwelithium simbi kune zvakanyanya kudiwa kwezvakatipoteredza.Naizvozvo,lithium mabhatiriisati yashandiswa kwenguva refu.Nekuvandudzwa kwesainzi uye tekinoroji, mabhatiri e-lithium atova makuru.

Lead-asidhi mabhatiri:

Lead-asidhi bhatiri (VRLA) bhatiri rekuchengetedza iro maelectrode ayo anonyanya kugadzirwa nemutobvu nemaokisisa ayo, uye ayo electrolyte iri sulfric acid solution.Mumamiriro ekubudiswa kwebhatiri ye-lead-acid, chikamu chikuru che electrode yakanaka inotungamirira diokisi, uye chikamu chikuru che electrode yakaipa inotungamira;muhurumende inopomerwa, zvikamu zvikuru zvezvakanaka uye zvisina kunaka electrodes zvinotungamirira sulfate.

Iro zita remagetsi ebhatiri re-sero-lead-asidhi i2.0V, inogona kuburitswa kusvika ku1.5V uye inogona kuchajwa kusvika ku2.4V.Mumaapplications, 6 single-cell lead-acid mabhatiri anowanzo shandiswa munhevedzano kugadzira 12V inotungamira-asidhi bhatiri.Kune zvakare 24V, 36V, 48V uye zvichingodaro.

Ndeipi yakachengeteka, lithium bhatiri kana lead-asidhi bhatiri?

Kubva pakuona kwekuchengetedzwa kwebhatiri kuchengetedza, mavharuvhu ekuchengetedza akagadzirwa pamasero e18650, ayo asingagoni kungosunungura zvakanyanya mukati memukati, asiwo nemuviri kubvisa bhatiri kubva kudunhu rekunze, iro rakaenzana nekuparadzanisa sero sero kuti ive nechokwadi chekuti Kuchengetedzeka. yemamwe masero ebhatiri mubhatiri pack.Mukuwedzera, lithium bhatiri packs inowanzogadzirirwa neBMS mabhodhi ekudzivirira, ayo anogona kunyatso kudzora chimiro chesero imwe neimwe mubhatiri pack, uye kugadzirisa zvakananga dambudziko rekuwedzera uye kuwedzera kubva kune chikonzero.

Lithium bhatiri BMS bhatiri manejimendi system inogona kupa dziviriro yakazara kune bhatiri, mabasa anosanganisira: kubhadharisa / kuburitsa yakakwirira uye yakaderera tembiricha kudzivirira;single cell overcharge / overdischarge voltage kudzivirira;kubhadharisa / kuburitsa overcurrent kudzivirira;cell balance;pfupi dunhu kudzivirira;Zviyeuchidzo nezvimwe.

Iyo electrolyte yelithium bhatiri packmushonga wakasanganiswa welithium munyu uye organic solvent, iyo inotengeswa inotengeswa lithium munyu inonzi lithium hexafluorophosphate.Ichi chinyorwa chinowanzoita kuora kwekupisa pakupisa kwakanyanya uye chinosangana ne thermochemical reaction nekutevera huwandu hwemvura uye organic solvents kuderedza Thermal kugadzikana kwe electrolyte.

Iyo simba lithium bhatiri inonyanya kushandisa lithium iron phosphate.Iyo PO bond mu lithium iron phosphate crystal yakagadzikana uye yakaoma kuparara.Kunyangwe pakupisa kwakanyanya kana kuwandisa, haizopunzike uye kuunza kupisa kana kuumba yakasimba oxidizing zvinhu se lithium cobaltate.Kuchengeteka kwakanaka.Zvinoshumwa kuti mukushanda chaiko, nhamba shoma yemasampuli yakawanikwa ichipisa panguva yekuongorora acupuncture kana pfupi-circuit, asi hapana chiitiko chekuputika chakaitika.Kuchengetedzwa kwe lithium bhatiri packs kwakagadziridzwa zvakanyanya.

Mukupesana, mabhatiri e-lead-acid haana dziviriro yeBMS system.Lead-asidhi mabhatiri anoita seari kushaikwa mukuchengetedzwa kwekuchengetedza kunze kwemavharuvhu ekuchengetedza.BMS dziviriro inenge isipo.Machaja mazhinji epasi haatombogone kudzima mushure mekuchajiswa zvizere.Kudzivirirwa kwekuchengetedza kuri kure nemabhatiri e lithium.Yakabatana nechaja yemhando yakaderera, zvakanaka kuti iwe uve muchimiro chakanaka.

Kuputika kwezvinoputika mumotokari dzemagetsi kunowanzoitika, mazhinji acho anokonzerwa nekuchaja kwebhatiri uye kubuda.Dzimwe nyanzvi dzakatsanangura kuti mabhatiri e-lead-acid anotora nguva yakareba kuti ajaire, uye kana achinge abhadhariswa kusvika kumagumo, mushure mekunge mapango maviri ashandurwa kuita zvinhu zvinoshanda, kana vakaramba vachichaja, huwandu hwemagetsi huchagadzirwa.Hydrogen, okisijeni gasi.Kana kuzara kwegasi iri rakasanganiswa richiita 4% mumhepo, kunonoka kutiza.Kana gomba rekubuditsa rakavharwa kana kuti gasi rakawandisa, rinoputika kana rasangana nemurazvo wakavhurika.Ichakuvadza bhatiri muchiedza, uye kukuvadza vanhu uye kukuvadza mumatambudziko akakomba.Ndiko kuti, kana bhatiri re-lead-acid ranyanya kubhadharwa, inowedzera mukana wekuputika.Parizvino, mabhatiri e-lead-acid ari pamusika haana kuita chero "kuchengetedzwa kwepamusoro", izvo zvinoita kuti mabhatiri e-lead-acid mukuchaja, kunyanya pakupera kwekuchaja, ane ngozi zvakanyanya.

Chekupedzisira, kana chimiro chebhatiri chakakuvadzwa nekuda kwekudhumhana netsaona, lead-asidhi mabhatiri anoita seakachengeteka kupfuura lithium mabhatiri.Zvisinei, munharaunda iyi yetsaona, zvinhu zvebheteri zvakatove zvichionekwa kune nzvimbo yakazaruka, uye kuputika hakugoneki kutaura nezvazvo.

Kubva pane njodzi dzekuchengetedza dziri pamusoro dzemabhatiri e-lead-asidhi uye mabhatiri e-lithium iron phosphate, zvinogona kuonekwa kuti njodzi huru yekuchengetedzwa kwemabhatiri e-lead-acid iri mumidziyo yavo.Maelectrodes emabhatiri e-lead-asidhi anonyanya kugadzirwa nemutobvu nemaokisi ayo, uye electrolyte inogadzirisa sulfuric acid.Kugadzikana kwezvinhu izvi zvinoumba hakuna kunyanya kukwirira.Kana tsaona yekuvuza kana kuputika ikaitika, kukuvadzwa kwakakonzerwa kuchave kwakanyanya kudarika iyo yebhatiri ye lithium.

Pfupiso:

Kubva pakuona kwekuchengetedzwa kwebhatiri uye redundancy dhizaini, inokwanisa mabhatiri e-lithium uye mabhatiri e-lead-asidhi anogona kuvimbisa zvizere kuchengetedzwa kwevashandisi, uye hapana mutsauko wakajeka wekuchengetedza.Ko lithium bhatiri kana lead acid bhatiri yakachengeteka here?Panguva ino, iyo yekuchengetedza chinhu chelithium mabhatiriichiri yakakwirira.
