Chitetezo cha mabatire a lithiamu ndi mabatire a lead-acid nthawi zonse akhala akukangana pakati pa ogwiritsa ntchito.Anthu ena amanena kuti mabatire a lithiamu ndi otetezeka kuposa mabatire a lead-acid, koma ena amaganiza mosiyana.Malinga ndi kapangidwe ka batri, mapaketi a batri a lithiamu omwe alipo tsopano ndi mabatire 18650 opakira, ndipo mabatire a acid-lead kwenikweni ndi mabatire opanda lead-acid okhala ndi ntchito yabwino yosindikiza, ndipo ziwopsezo za awiriwa ndizofanana.Ndani ali otetezeka, ingoyang'anani pansi ndipo mudzadziwa!

lithiamu batire:

Mabatire a lithiamu ndi mtundu wa mabatire omwe amagwiritsa ntchito chitsulo cha lithiamu kapena aloyi ya lithiamu ngati zinthu zopanda ma elekitirodi ndipo amagwiritsa ntchito njira ya electrolyte yopanda madzi.Mabatire a lithiamu amatha kugawidwa m'magulu awiri: mabatire a lithiamu zitsulo ndi mabatire a lithiamu-ion.Mu 1912, mabatire a lithiamu zitsulo adapangidwa koyamba ndikuphunziridwa ndi Gilbert N. Lewis.Chifukwa champhamvu kwambiri yamankhwala a lithiamu zitsulo, kukonza, kusungirako, ndi kugwiritsa ntchito zitsulo za lithiamu kumakhala ndi zofunika kwambiri zachilengedwe.Chifukwa chake,mabatire a lithiamusanagwiritsidwe ntchito kwa nthawi yayitali.Ndi chitukuko cha sayansi ndi teknoloji, mabatire a lithiamu tsopano akhala otchuka.

Mabatire a lead-acid:

Batire ya lead-acid (VRLA) ndi batire yosungira yomwe maelekitirodi ake amapangidwa makamaka ndi lead ndi ma oxides ake, ndipo electrolyte yake ndi sulfuric acid solution.Pakutha kwa batire ya acid-acid, gawo lalikulu la electrode yabwino ndi lead dioxide, ndipo gawo lalikulu la electrode yoyipa ndi lead;mu boma mlandu, zigawo zikuluzikulu za maelekitirodi zabwino ndi zoipa ndi lead sulphate.

Mphamvu yamagetsi ya batire ya cell lead-acid ndi 2.0V, yomwe imatha kutulutsidwa mpaka 1.5V ndipo imatha kulipitsidwa mpaka 2.4V.M'mapulogalamu, mabatire 6 a lead-cell lead-acid nthawi zambiri amagwiritsidwa ntchito motsatizana kupanga batire ya 12V ya lead-acid.Palinso 24V, 36V, 48V ndi zina zotero.

Ndi chiyani chomwe chili chotetezeka, batri la lithiamu kapena batri ya acid-acid?

Kuchokera pakuwona chitetezo cha chitetezo cha batri, ma valve otetezera amapangidwa pa maselo a 18650, omwe sangangotulutsa kupanikizika kwakukulu kwa mkati, komanso kumasula batri kuchokera kudera lakunja, lomwe liri lofanana ndi kudzipatula kwa selo kuti liwonetsetse kuti chitetezo. ma cell ena a batri mu paketi ya batri.Kuphatikiza apo, mapaketi a batri a lithiamu nthawi zambiri amakhala ndi matabwa oteteza BMS, omwe amatha kuwongolera bwino momwe selo lililonse mu paketi ya batri liri, ndikuthetsa vuto la kuchulukirachulukira komanso kutulutsa kwambiri pazifukwa zake.

Lithium batire BMS dongosolo kasamalidwe batire akhoza kupereka chitetezo chokwanira kwa batire, ntchito zikuphatikizapo: kulipira / kutulutsa chitetezo chapamwamba ndi chotsika kutentha;single cell overcharge / overdischarge voteji chitetezo;chitetezo / kutulutsa overcurrent chitetezo;cell balance;chitetezo chaching'ono;Zikumbutso ndi zina.

Mphamvu ya electrolytelithiamu batire paketindi njira yosakanikirana ya mchere wa lithiamu ndi organic solvent, yomwe lifiyamu mchere wogulitsidwa ndi lithiamu hexafluorophosphate.Nkhaniyi imakonda kuwonongeka chifukwa cha kutentha kwambiri ndipo imakhala ndi thermochemical reaction ndi kuchuluka kwa madzi ndi zosungunulira za organic kuti muchepetse kukhazikika kwamafuta a electrolyte.

Mphamvu ya lithiamu batire makamaka imagwiritsa ntchito lithiamu iron phosphate.Chomangira cha PO mu lithiamu iron phosphate crystal ndi chokhazikika komanso chovuta kuwola.Ngakhale kutentha kwambiri kapena kuchulukirachulukira, sikungagwere ndikupanga kutentha kapena kupanga zinthu zolimba za okosijeni monga lithiamu cobaltate.Chitetezo chabwino.Zimanenedwa kuti mu ntchito yeniyeni, chiwerengero chochepa cha zitsanzo chinapezeka kuti chiwotchedwa panthawi ya acupuncture kapena kuyesa kwafupipafupi, koma palibe kuphulika komwe kunachitika.Chitetezo cha mapaketi a batri a lithiamu chasinthidwa kwambiri.

Mosiyana ndi zimenezi, mabatire a lead-acid alibe chitetezo cha dongosolo la BMS.Mabatire a lead-acid akuwoneka kuti alibe chitetezo chachitetezo kupatula ma valve oteteza.BMS chitetezo pafupifupi kulibe.Ma charger ambiri otsika samatha ngakhale kuzimitsa atachangidwa kwathunthu.Chitetezo chachitetezo chili kutali ndi mabatire a lithiamu.Kuphatikizidwa ndi charger yotsika, ndikwabwino kuti mukhale bwino.

Kuphulika kodzidzimutsa m'magalimoto amagetsi nthawi zambiri kumachitika, zomwe zambiri zimayamba chifukwa cha kulipiritsa batire ndi kutulutsa.Akatswiri ena afotokoza kuti mabatire a lead-acid amatenga nthawi yayitali kuti azilipiritsa, ndipo akamalizidwa mpaka kumapeto, mizati iwiri ikasinthidwa kukhala zinthu zogwira mtima, ngati apitiliza kulipira, magetsi ambiri amapangidwa.Hyrojeni, mpweya wa oxygen.Pamene mpweya wosakanikiranawu umakhala 4% mumlengalenga, ndi mochedwa kwambiri kuti athawe.Ngati dzenje lotayira latsekedwa kapena gasi lachuluka, limaphulika likakumana ndi lawi lotseguka.Idzawononga batire pakuwala, ndikuvulaza anthu ndikuwononga kwambiri.Ndiye kuti, batire ya asidi-lead ikangochulukitsidwa, imawonjezera mwayi wophulika.Pakalipano, mabatire a lead-acid pamsika sanachitepo "chitetezo chowonjezera", chomwe chimapangitsa mabatire a lead-acid pakulipiritsa, makamaka kumapeto kwa kulipiritsa, koopsa kwambiri.

Pomaliza, ngati mawonekedwe a batri awonongeka chifukwa chagundana mwangozi, mabatire a lead-acid amawoneka otetezeka kuposa mabatire a lithiamu.Komabe, pamlingo uwu wa ngozi, zinthu za batri zakhala zikuwonekera kale kumalo otseguka, ndipo kuphulika sikungathe kuyankhula.

Kuchokera paziwopsezo zachitetezo pamwambapa za mabatire a lead-acid ndi mabatire a lithiamu iron phosphate, zitha kuwoneka kuti chiwopsezo chachikulu chachitetezo cha mabatire a lead-acid chagona muzinthu zawo.Ma electrode a mabatire a lead-acid amapangidwa makamaka ndi mtovu ndi ma oxide ake, ndipo electrolyte ndi njira ya sulfuric acid.Kukhazikika kwazinthu zokhazikitsidwa izi sizokwera kwambiri.Ngati ngozi yotuluka kapena kuphulika ichitika, zovulaza zomwe zachitika zimakhala zazikulu kuposa za mabatire a lithiamu.

Chidule cha nkhani:

Kuchokera pakuwona kwa chitetezo cha batri ndi mapangidwe a redundancy, mabatire a lithiamu oyenerera ndi mabatire a lead-acid amatha kutsimikizira chitetezo cha ogwiritsa ntchito, ndipo palibe kusiyana koonekeratu kwa chitetezo.Kodi batire ya lithiamu kapena batire ya asidi ya lead ndiyotetezeka?Panthawi imeneyi, chitetezo chinthumabatire a lithiamuakadali apamwamba.
