Kuti atulutse mphamvu zomwe zimasungidwa masana usiku,magetsi a mumsewu oyendetsedwa ndi dzuwaamagwiritsidwa ntchito kwambiri powunikira panja. Mabatire a Lithium iron phosphate (LFP), omwe ndi ofunikira kwambiri, ndi mtundu wofala kwambiri wa mabatire. Mabatire awa ndi osavuta kuyika pamitengo yowunikira kapena mapangidwe ophatikizika chifukwa cha kulemera kwawo kwakukulu ndi kukula kwake. Palibenso nkhawa kuti kulemera kwa mabatire kudzawonjezera kupsinjika pamtengowo, mosiyana ndi mitundu yakale.
Ubwino wawo wambiri ukuonekeranso chifukwa chakuti amagwira ntchito bwino kwambiri ndipo ali ndi mphamvu zambiri kuposa mabatire a lead-acid. Ndiye kodi zigawo zazikulu za batire iyi ya lithiamu iron phosphate yomwe imasintha ndi ziti?
1. Kathodi
Lithium ndi gawo lofunika kwambiri la mabatire a lithiamu, monga momwe dzinalo likusonyezera. Koma Lithium ndi chinthu chosakhazikika kwambiri. Chogwiritsidwa ntchito nthawi zambiri chimakhala lithiamu oxide, chisakanizo cha lithiamu ndi mpweya. Cathode, yomwe imapanga magetsi kudzera mu reaction ya mankhwala, imapangidwa powonjezera zowonjezera ndi zomangira. Cathode ya batire ya lithiamu imalamulira mphamvu yake yamagetsi komanso mphamvu yake.
Kawirikawiri, kuchuluka kwa lithiamu mu chinthu chogwira ntchito, mphamvu ya batri imakhala yayikulu, kusiyana komwe kulipo pakati pa cathode ndi anode kumakhala kwakukulu, ndipo mphamvu yamagetsi imakhala yayikulu. Mosiyana ndi zimenezi, mphamvu ya lithiamu imakhala yochepa, mphamvu yamagetsi imakhala yochepa komanso mphamvu yamagetsi imakhala yochepa.
2. Anode
Pamene mphamvu yamagetsi yosinthidwa ndi solar panel ikuchaja batire, ma lithiamu ion amasungidwa mu anode. Anode imagwiritsanso ntchito zinthu zogwira ntchito, zomwe zimalola kuyamwa kapena kutulutsa ma lithiamu ion omwe amatulutsidwa kuchokera ku cathode pamene mphamvu yamagetsi ikuyenda kudzera mu dera lakunja. Mwachidule, imalola kutumiza ma elekitironi kudzera mu mawaya.
Chifukwa cha kapangidwe kake kokhazikika, graphite nthawi zambiri imagwiritsidwa ntchito ngati chinthu chogwira ntchito cha anode. Sichimasintha kwambiri voliyumu, sichimasweka, ndipo chimatha kupirira kusintha kwakukulu kwa kutentha kwa chipinda popanda kuvulala. Komanso, ndi yoyenera kupanga anode chifukwa cha mphamvu yake yochepa yamagetsi.
3. Electrolyte
Zoopsa zachitetezo zimaposa kulephera kupanga magetsi ngati ma lithiamu ion adutsa mu electrolyte. Kuti apange mphamvu yofunikira, ma lithiamu ion amangofunika kuyenda pakati pa anode ndi cathode. Electrolyte imagwira ntchito yofunika kwambiri pa ntchito yoletsa iyi. Ma electrolyte ambiri amapangidwa ndi mchere, zosungunulira, ndi zowonjezera. Mchere umagwira ntchito makamaka ngati njira zoyendetsera kayendedwe ka ma lithiamu ion, pomwe zosungunulira ndi madzi omwe amagwiritsidwa ntchito kusungunula mchere. Zowonjezera zimakhala ndi ntchito yapadera.
Electrolyte iyenera kukhala ndi mphamvu yoyendetsa ma ionic komanso kutchinjiriza kwamagetsi kuti igwire ntchito mokwanira ngati njira yotumizira ma ionic ndikuchepetsa kutulutsa madzi. Kuti zitsimikizire kuti mphamvu yoyendetsa ma ionic ikugwira ntchito, nambala ya lithiamu-ion ya electrolyte iyeneranso kusungidwa; kuchuluka kwa 1 ndikoyenera.
4. Cholekanitsa
Cholekanitsa chimalekanitsa makamaka cathode ndi anode, kuletsa kuyenda kwa ma elekitironi mwachindunji ndi ma short circuits, ndikungopanga njira zoyendetsera ma ion.
Polyethylene ndi polypropylene nthawi zambiri zimagwiritsidwa ntchito popanga zinthuzi. Chitetezo chabwino ku ma short circuits amkati, chitetezo chokwanira ngakhale m'malo odzaza kwambiri, zigawo zopyapyala za electrolyte, kukana kwamkati kochepa, kugwira ntchito bwino kwa batri, komanso kukhazikika bwino kwa makina ndi kutentha zonse zimathandiza kuti batri likhale labwino.
Magetsi a mumsewu a Tianxiang oyendetsedwa ndi dzuwaZonsezi zimayendetsedwa ndi mabatire a lithiamu apamwamba kwambiri okhala ndi maselo osankhidwa mosamala okhala ndi mphamvu zambiri. Ndi oyenera kutentha ndi chinyezi chakunja, amakhala ndi moyo wautali, amatha kuyatsa ndi kutulutsa mphamvu zambiri, komanso amateteza kutentha ndi kuzizira kwambiri. Mabatirewa amateteza mphamvu zambiri ku ma circuit afupiafupi, kutulutsa mphamvu zambiri, komanso kudzaza mphamvu zambiri kumatsimikizira kusungidwa kwa mphamvu nthawi zonse komanso kugwira ntchito kwa nthawi yayitali, zomwe zimathandiza kuti magetsi azigwiritsidwa ntchito nthawi zonse ngakhale pa mitambo kapena mvula. Kufananiza bwino ma solar panels ndi mabatire a lithiamu apamwamba kumatsimikizira kuti magetsi ndi odalirika komanso kuti ndalama zosamalira zizikhala zochepa.
