Chiyambi:
Mabatire amatha kugawidwa mokulira m'magulu atatu: mabatire a mankhwala, mabatire akuthupi ndi mabatire achilengedwe. Mabatire a Chemical ndi omwe amagwiritsidwa ntchito kwambiri pamagalimoto amagetsi.
Battery ya Chemical: Battery ya chemical ndi chipangizo chomwe chimasintha mphamvu ya mankhwala kukhala mphamvu yamagetsi pogwiritsa ntchito mankhwala. Amakhala ndi ma elekitirodi abwino komanso oyipa komanso ma electrolyte.
Batire lakuthupi: Batire lakuthupi limasintha mphamvu zakuthupi (monga mphamvu ya dzuwa ndi mphamvu zamakina) kukhala mphamvu yamagetsi kudzera mukusintha kwathupi.
Magulu a batri a Chemical: Kuchokera pamawonekedwe apangidwe, amatha kugawidwa m'magulu awiri: mabatire osungira (kuphatikiza mabatire oyambira ndi mabatire achiwiri) ndi ma cell amafuta. Mabatire oyambira: angagwiritsidwe ntchito kamodzi kokha, zinthu zogwira ntchito sizingasinthidwe, zotulutsa zokha ndizochepa, kukana kwamkati kumakhala kwakukulu, ndipo mphamvu zenizeni zenizeni komanso kuchuluka kwa voliyumu ndizokwera.
Mabatire achiwiri: amatha kulipiritsidwa ndikutulutsidwa mobwerezabwereza, zinthu zomwe zimagwira zimatha kusinthidwa, ndipo zimagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zolipirira. Mitundu yambiri pamsika pano imagwiritsa ntchito mabatire achiwiri omwe amathanso kuwonjezeredwa kuyendetsa galimoto. Mabatire achiwiri amagawidwa kukhala mabatire a lead-acid, mabatire a nickel-cadmium, mabatire a nickel-metal hydride ndi mabatire a lithiamu molingana ndi zida zosiyanasiyana za electrode. Masiku ano, makampani opanga magalimoto pamsika amagwiritsa ntchito kwambirimabatire a lithiamu, ndipo ena amagwiritsa ntchito mabatire a nickel-metal hydride.
Tanthauzo la batri ya lithiamu
Batire ya lithiamundi batire yomwe imagwiritsa ntchito zitsulo za lithiamu kapena aloyi ya lithiamu ngati zinthu zabwino kapena zoyipa zama elekitirodi komanso njira yopanda madzi ya electrolyte.
Kuthamangitsa ndi kutulutsa batri ya lithiamu makamaka kumadalira kayendedwe ka lithiamu ion (Li +) pakati pa ma elekitirodi abwino ndi oipa. Pamene kulipiritsa, ayoni lithiamu ndi deintercalated ku electrode zabwino ndi ophatikizidwa mu electrode zoipa kudzera electrolyte, ndi electrode negative ali mu lithiamu wolemera boma; chosiyana ndi chowona pakutulutsa.
Electrochemical mfundo ya lithiamu-ion batire
Njira yabwino yochitira ma elekitirodi: LiCoO2 → Li1-xCoO2 + xLi+ + xe-
Njira zoyipa zama elekitirodi: C + xLi+ + xe- → CLix
Mabatire a lithiamu-ion ali ndi mphamvu zochulukirapo, moyo wautali komanso kutsika kwamadzimadzi, ndipo amagwiritsidwa ntchito kwambiri m'mafoni a m'manja, ma laputopu ndi magalimoto amagetsi.
Minda yofunsira yamabatire a lithiamuamagawidwa makamaka kukhala mphamvu ndi zopanda mphamvu. Magawo amagetsi ogwiritsira ntchito batri ya lithiamu-ion amaphatikizapo magalimoto amagetsi, zida zamagetsi, ndi zina; minda yopanda mphamvu imaphatikizapo zida zamagetsi zogula ndi malo osungirako mphamvu, ndi zina.
Kupanga ndi kugawa kwa mabatire a lithiamu
Mabatire a lithiamu amapangidwa makamaka ndi magawo anayi: zinthu zabwino zama elekitirodi, zinthu zoyipa zama elekitirodi, ma electrolyte ndi zolekanitsa mabatire. Zipangizo zopanda ma elekitirodi zimakhudza makamaka magwiridwe antchito oyambira komanso kuzungulira kwa mabatire a lithiamu-ion. Ma electrode a lithiamu batire amagawika m'magulu awiri: zida za kaboni ndi zinthu zopanda mpweya. Kugwiritsa ntchito kwambiri pamsika ndi zinthu za graphite negative electrode pakati pa zinthu za carbon, zomwe ma graphite ochita kupanga ndi ma graphite achilengedwe amakhala ndi ntchito zazikulu zamafakitale. Ma elekitirodi opangidwa ndi silicon ndiye cholinga cha kafukufuku wopangidwa ndi opanga ma elekitirodi akuluakulu ndipo ndi chimodzi mwazinthu zatsopano zama elekitirodi zomwe zitha kugwiritsidwa ntchito kwambiri mtsogolo.
Mabatire a lithiamuamagawidwa kukhala mabatire a lithiamu cobalt okusayidi, mabatire a lithiamu iron phosphate, mabatire a ternary, etc. malinga ndi zinthu zabwino za elekitirodi;
Malinga ndi mawonekedwe a mankhwalawa, amagawidwa kukhala mabatire apakati, mabatire a cylindrical ndi mabatire a paketi yofewa;
Malinga ndi zochitika zogwiritsira ntchito, amatha kugawidwa mumagetsi ogula, kusungirako mphamvu ndi mabatire amphamvu. Pakati pawo, mabatire a lithiamu ogula amagwiritsidwa ntchito makamaka muzinthu za 3C; mabatire osungira mphamvu amagwiritsidwa ntchito makamaka posungira mphamvu zapakhomo ndikugawa zodziyimira pawokha zosungirako mphamvu zamagetsi monga mphamvu ya dzuwa ndi mphamvu yamphepo; mabatire amphamvu amagwiritsidwa ntchito makamaka pamagalimoto osiyanasiyana amagetsi, zida zamagetsi ndi magalimoto atsopano amagetsi.
Mapeto
Heltec ipitiliza kukonzanso chidziwitso chodziwika bwino cha sayansimabatire a lithiamu. Ngati muli ndi chidwi, mukhoza kumvetsera. Nthawi yomweyo, timakupatsirani mapaketi apamwamba a lithiamu batire kuti mugule ndikupereka ntchito zosinthidwa kuti zikwaniritse zosowa zanu.
Heltec Energy ndi mnzanu wodalirika pakupanga mapaketi a batri. Ndi kuyang'ana kwathu kosalekeza pa kafukufuku ndi chitukuko, pamodzi ndi mitundu yosiyanasiyana ya zida za batri, timapereka mayankho okhazikika kuti tikwaniritse zosowa zamakampani. Kudzipereka kwathu pakuchita bwino, mayankho ogwirizana, ndi mgwirizano wamphamvu wamakasitomala zimatipangitsa kukhala osankha kwa opanga mapaketi a batri ndi ogulitsa padziko lonse lapansi.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, musazengereze kuterokufikira kwa ife.
