Chiyambi:
Mabatire akhoza kugawidwa m'magulu atatu: mabatire a mankhwala, mabatire enieni ndi mabatire achilengedwe. Mabatire a mankhwala ndi omwe amagwiritsidwa ntchito kwambiri m'magalimoto amagetsi.
Batire ya mankhwala: Batire ya mankhwala ndi chipangizo chomwe chimasintha mphamvu ya mankhwala kukhala mphamvu yamagetsi kudzera mu zochita za mankhwala. Chimakhala ndi ma electrode abwino ndi oipa ndi ma electrolyte.
Batire yeniyeni: Batire yeniyeni imasintha mphamvu yeniyeni (monga mphamvu ya dzuwa ndi mphamvu ya makina) kukhala mphamvu yamagetsi kudzera mu kusintha kwa thupi.
Kugawa mabatire a mankhwala: Kuchokera pamalingaliro a kapangidwe kake, akhoza kugawidwa m'magulu awiri: mabatire osungira (kuphatikiza mabatire oyambira ndi mabatire ena) ndi ma cell amafuta. Mabatire oyambira: angagwiritsidwe ntchito kamodzi kokha, zinthu zogwira ntchito sizingasinthe, chotulutsa chokha ndi chaching'ono, kukana kwamkati ndi kwakukulu, ndipo mphamvu yeniyeni ya unyinji ndi mphamvu yeniyeni ya voliyumu ndi yayikulu.
Mabatire achiwiri: amatha kuchajidwa ndi kutulutsidwa mobwerezabwereza, zinthu zogwira ntchito zimatha kusinthidwa, ndipo zimagwiritsidwa ntchito kwambiri m'zida zosiyanasiyana zochajira. Mitundu yambiri yomwe ili pamsika pakadali pano imagwiritsa ntchito mabatire ena omwe amatha kuchajidwanso kuti iyendetse galimotoyo. Mabatire achiwiri amagawidwa m'mabatire a lead-acid, mabatire a nickel-cadmium, mabatire a nickel-metal hydride ndi mabatire a lithiamu malinga ndi zipangizo zosiyanasiyana zabwino za electrode. Pakadali pano, makampani ogulitsa magalimoto pamsika amagwiritsa ntchito mabatire a lithiamu, ndipo ochepa amagwiritsa ntchito mabatire a nickel-metal hydride.
Tanthauzo la batri ya lithiamu
Batri ya Lithium ndi batri yomwe imagwiritsa ntchito chitsulo cha lithiamu kapena aloyi ya lithiamu ngati zinthu zabwino kapena zoyipa za electrode komanso yankho la electrolyte losakhala lamadzi.
Njira yochajira ndi kutulutsa mphamvu ya batri ya lithiamu imadalira kwambiri kayendedwe ka ma ayoni a lithiamu (Li+) pakati pa ma electrode abwino ndi oipa. Akachajira, ma ayoni a lithiamu amachotsedwa mu electrode yabwino ndikulowetsedwa mu electrode yoipa kudzera mu electrolyte, ndipo electrode yoipa imakhala ndi lithiamu yambiri; zosiyana ndi izi zimakhala zoona akamachajira mphamvu.
Mfundo yamagetsi ya batri ya lithiamu-ion
Fomula yabwino ya ma electrode reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Fomula yoyeserera ya ma electrode oipa: C + xLi + + xe- → CLix
Mabatire a lithiamu-ion ali ndi mphamvu zambiri, amakhala nthawi yayitali komanso samadzitulutsa okha, ndipo amagwiritsidwa ntchito kwambiri m'mafoni am'manja, ma laputopu ndi magalimoto amagetsi.
Magawo ogwiritsira ntchito mabatire a lithiamu-ion amagawidwa makamaka m'magulu amagetsi ndi osakhala amphamvu. Magawo ogwiritsira ntchito mabatire a lithiamu-ion ndi monga magalimoto amagetsi, zida zamagetsi, ndi zina zotero; magawo osakhala amphamvu ndi monga magetsi amagetsi ndi malo osungira mphamvu, ndi zina zotero.
Kapangidwe ndi magulu a mabatire a lithiamu
Mabatire a Lithium-ion amapangidwa makamaka ndi magawo anayi: zipangizo zabwino za electrode, zipangizo zoyipa za electrode, ma electrolyte ndi olekanitsa mabatire. Zipangizo zoyipa za electrode zimakhudza kwambiri magwiridwe antchito oyamba ndi kayendedwe ka mabatire a lithiamu-ion. Ma electrode oipa a batire ya Lithium amagawidwa m'magulu awiri: zipangizo za kaboni ndi zinthu zopanda kaboni. Ntchito yogwiritsidwa ntchito kwambiri pamsika ndi zinthu za graphite negative electrode pakati pa zipangizo za kaboni, zomwe graphite yochita kupanga ndi graphite yachilengedwe zimagwiritsidwa ntchito kwambiri m'mafakitale. Ma electrode oipa ochokera ku silicon ndi omwe amafufuzidwa kwambiri ndi opanga ma electrode oipa ndipo ndi chimodzi mwa zinthu zatsopano zoyipa zomwe zingagwiritsidwe ntchito kwambiri mtsogolo.
Mabatire a lithiamu-ion amagawidwa m'mabatire a lithiamu cobalt oxide, mabatire a lithiamu iron phosphate, mabatire a ternary, ndi zina zotero. malinga ndi zipangizo zabwino za electrode;
Malinga ndi mtundu wa chinthucho, amagawidwa m'mabatire a sikweya, mabatire a cylindrical ndi mabatire ofewa;
Malinga ndi momwe zinthu zilili, zitha kugawidwa m'magulu amagetsi, malo osungira mphamvu ndi mabatire amagetsi. Pakati pawo, mabatire a lithiamu amagwiritsidwa ntchito kwambiri muzinthu za 3C; mabatire osungira mphamvu amagwiritsidwa ntchito makamaka posungira mphamvu zapakhomo komanso posungira mphamvu zamagetsi zodziyimira pawokha monga mphamvu ya dzuwa ndi mphamvu ya mphepo; mabatire amagetsi amagwiritsidwa ntchito kwambiri m'magalimoto osiyanasiyana amagetsi, zida zamagetsi ndi magalimoto atsopano amagetsi.
Mapeto
Heltec ipitiliza kusinthitsa chidziwitso chodziwika bwino cha sayansi chokhudza mabatire a lithiamu. Ngati mukufuna, mutha kulabadira. Nthawi yomweyo, timakupatsirani mapaketi apamwamba a mabatire a lithiamu kuti mugule ndikupereka ntchito zomwe mwasankha kuti zigwirizane ndi zosowa zanu.
Heltec Energy ndi mnzanu wodalirika pakupanga mabatire. Popeza tikuyang'ana kwambiri kafukufuku ndi chitukuko, pamodzi ndi zida zathu zambiri za batire, timapereka mayankho amodzi kuti tikwaniritse zosowa zomwe zikusintha zamakampani. Kudzipereka kwathu ku ntchito yabwino kwambiri, mayankho okonzedwa bwino, komanso mgwirizano wamphamvu ndi makasitomala zimatipangitsa kukhala chisankho chabwino kwambiri kwa opanga mabatire ndi ogulitsa padziko lonse lapansi.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, chonde musazengereze kutifunsatitumizireni uthenga.
