Kapangidwe kalithiamu batire

Zomwe zili m'mabatire a lithiamu makamaka zimaphatikizapo zinthu zabwino zama elekitirodi, zinthu zopanda ma elekitirodi, olekanitsa, ma electrolyte, ndi ma casings.

1. Pakati pa zipangizo zabwino za electrode, zipangizo zomwe zimagwiritsidwa ntchito kwambiri ndi lithiamu cobaltate, lithiamu manganenate, lithiamu iron phosphate ndi zipangizo za ternary (ma polima a faifi tambala, cobalt ndi manganese).Zinthu zabwino zama elekitirodi zimakhala ndi gawo lalikulu (chiwerengero cha misa cha zinthu zabwino ndi zoyipa zama elekitirodi ndi 3: 1 ~ 4: 1), chifukwa magwiridwe antchito a ma elekitirodi amakhudza mwachindunji magwiridwe antchito a batri ya lithiamu-ion, ndi mtengo wake umatsimikiziranso mwachindunji mtengo wa batri.
2. Pakati pa zinthu zoipa elekitirodi, masoka graphite ndi yokumba graphite panopa waukulu zoipa elekitirodi zipangizo.Zinthu za anode zomwe zikuwunikidwa zikuphatikizapo nitrides, polyaspartic acid, tin-based oxides, tin alloys, nano-anode materials, ndi zinthu zina za intermetallic.Monga chimodzi mwazinthu zinayi zazikulu zamabatire a lithiamu, zinthu zoyipa zama elekitirodi zimagwira ntchito yofunika kwambiri pakuwongolera mphamvu ya batri ndi ntchito yozungulira, ndipo zili pachimake pakatikati pamakampani a batire a lithiamu.
3. Zida zopangira ma diaphragm zomwe zimatengera msika makamaka ndi ma diaphragm a polyolefin, omwe amapangidwa makamaka ndi polyethylene ndi polypropylene.Mu dongosolo la olekanitsa batire lifiyamu, olekanitsa ndi chimodzi mwa zigawo zikuluzikulu zamkati.Kuchita kwa olekanitsa kumatsimikizira mawonekedwe a mawonekedwe ndi kukana kwamkati kwa batri, zomwe zimakhudza mwachindunji mphamvu, kuzungulira ndi chitetezo cha batri.Cholekanitsa chokhala ndi magwiridwe antchito abwino kwambiri chimagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito onse a batri.
4. Electrolyte nthawi zambiri imapangidwa ndi zosungunulira za organic, electrolyte lithiamu salt, zowonjezera zofunika ndi zida zina zopangira mugawo linalake.Electrolyte imagwira ntchito yoyendetsa ma ion pakati pa ma elekitirodi abwino ndi oipa a batire ya lithiamu, yomwe ndi chitsimikizo champhamvu kwambiri komanso mphamvu yayikulu ya batri ya lithiamu ion.
5. Chosungira cha batri: chogawanika kukhala chotengera chachitsulo, choyikapo cha aluminiyamu, choyikapo chitsulo cha nickel (cha mabatire a cylindrical), filimu ya aluminiyamu-pulasitiki (zotengera zofewa), ndi zina zotero, komanso chipewa cha batri, chomwe chilinso malo abwino komanso oyipa a batire
6. Mfundo ya Battery ntchito
7. Batire ikaperekedwa, ma ion a lithiamu amapangidwa pa electrode yabwino ya batri, ndipo ma ion a lithiamu amapita ku electrode yoyipa kudzera mu electrolyte.Kapangidwe ka kaboni ka electrode yoyipa kumakhala ndi pores ambiri, ndipo ayoni a lithiamu omwe amafika ku electrode yoyipa amaphatikizidwa mu ma micropores a kaboni wosanjikiza.Ma ion a lithiamu akaphatikizidwa, mphamvu yowonjezera idzakhala yokwera kwambiri.Batire ikatulutsidwa, ma lithiamu ions omwe amaikidwa mu carbon layer ya electrode negative amatuluka ndikubwerera ku electrode yabwino.Ma ion a lithiamu omwe amabwereranso ku electrode yabwino, amakweza mphamvu yotulutsa.Nthawi zambiri, mphamvu yotulutsa imatanthawuza mphamvu yotulutsa.Pa nthawi yolipiritsa ndi kutulutsa batri ya lithiamu, ma lithiamu ions ali mumayendedwe oyenda kuchokera ku electrode yabwino kupita ku electrode yoipa.Ngati chithunzi cha batri ya lithiamu chikufanizidwa ndi mpando wogwedeza, malekezero awiri a mpando wogwedeza ndi ma electrode abwino ndi oipa a batri, ndipo ma lithiamu ion ali ngati othamanga, akuthamanga mmbuyo ndi mtsogolo pakati pa malekezero awiri a mpando wogwedeza. .Chifukwa chake mabatire a lithiamu amatchedwanso mabatire a rocking chair.
