Chiyambi:
Batire ya lithiamundi batire yomwe imagwiritsa ntchito lithiamu zitsulo kapena lithiamu pawiri ngati electrode chuma. Chifukwa cha nsanja yamagetsi yamagetsi, kulemera kopepuka komanso moyo wautali wautumiki wa lithiamu, batire ya lithiamu yakhala mtundu waukulu wa batri womwe umagwiritsidwa ntchito kwambiri pamagetsi ogula, makina osungira mphamvu, magalimoto amagetsi ndi madera ena. Lero, tiyeni tiwone njira zingapo zomaliza zopangira batire ya lithiamu, Formation-OCV testcapacity-Separation.
Mapangidwe
Kupanga batire ya lithiamu ndiye njira yoyamba yolipirira batire batire la lithiamu litadzazidwa ndi madzi.
Njira imeneyi akhoza yambitsa yogwira zinthu batire ndi yambitsa ndilithiamu batire. Panthawi imodzimodziyo, mchere wa lifiyamu umakhudzidwa ndi electrolyte kupanga filimu yolimba ya electrolyte (SEI) kumbali yolakwika ya electrode ya batri ya lithiamu. Kanemayu angalepheretsenso kuchitika kwa mbali, potero kuchepetsa kutayika kwa lifiyamu yogwira mu batire ya lithiamu. Ubwino wa SEI umakhudza kwambiri moyo wozungulira, kutaya mphamvu koyamba, komanso magwiridwe antchito a mabatire a lithiamu.
OCV mayeso
Kuyesa kwa OCV ndikuyesa kwamagetsi otseguka, kukana kwa AC mkati ndi voteji ya cell imodzi. Ndi gawo lofunika kwambiri pakupanga batire. Iyenera kukwaniritsa kulondola kwa OCV kwa 0.1mv ndi kulondola kwamagetsi a chipolopolo cha 1mv. Mayeso a OCV amagwiritsidwa ntchito kusanja ma cell.
Njira yopanga mayeso a OCV
Mayeso a OCV makamaka amayesa mawonekedwe a batri pokanikizira ma probe olumikizidwa ndi choyezera voteji ndi choyesa chamkati chamkati pamakutu abwino komanso oyipa a batire yofewa.
Mayeso apano a OCV makamaka amayesa semi-automatic. Wogwira ntchito pamanja amayika batire mu chipangizo choyesera, ndipo kafukufuku wa chipangizo choyesera amalumikizana ndi makutu abwino komanso oyipa a batri kuti achite mayeso a OCV pa batri, kenako amatsitsa ndikusintha batire pamanja.
Lithium batire mphamvu gawo
Pambuyo pa gulu lamabatire a lithiamuamapangidwa, ngakhale kukula kwake kuli kofanana, mphamvu ya mabatire idzakhala yosiyana. Chifukwa chake, ayenera kulipiritsidwa kwathunthu pazidazo molingana ndi zomwe zafotokozedwera, kenako ndikutulutsidwa (kutulutsidwa kwathunthu) molingana ndi zomwe zanenedwa. Nthawi yotengedwa kuti mutulutse batire mochulukitsidwa ndi kutulutsa kwapano ndi kuchuluka kwa batire.
Malingana ngati mphamvu yoyesedwa ikukumana kapena kupitirira mphamvu yomwe idapangidwira, batri ya lithiamu ndiyoyenera, ndipo batri yokhala ndi mphamvu yocheperapo yomwe idapangidwa silingaganizidwe kuti ndi batri yoyenerera. Njira yosankha mabatire oyenerera kudzera pakuyesa mphamvu imatchedwa kugawa mphamvu.
Udindo walithiamu batirekugawanika kwa mphamvu sikumangokhalira kukhazikika kwa filimu ya SEI, komanso kungafupikitse nthawi yogwiritsidwa ntchito ndi njira yogawa mphamvu, kuchepetsa kugwiritsa ntchito mphamvu ndikuwonjezera mphamvu zopanga.
Cholinga china cha kugawa mphamvu ndikugawa ndi kugawa mabatire, ndiko kuti, kusankha ma monomers omwe ali ndi kukana kwamkati komweku komanso kuthekera kophatikiza. Mukaphatikiza, okhawo omwe ali ndi magwiridwe ofanana kwambiri amatha kupanga batire paketi.
Mapeto
Pomaliza, alithiamu batirewamaliza njira zonse za cell ya batri pambuyo poyang'anitsitsa maonekedwe onse, kupopera mankhwala a grade code, kuyang'anitsitsa kalasi, ndi kulongedza, kudikirira kuti asonkhanitsidwe mu paketi ya batri.
Ponena za mapaketi a batri, ngati muli ndi lingaliro la mapaketi a batri a DIY, Heltec imaperekaoyesa mphamvu ya batrikukulolani kuti mumvetse magawo a batri yanu ndikuganizira ngati kuli koyenera kusonkhanitsa paketi ya batri yomwe mukufuna. Timaperekansobatire yofananakusunga mabatire anu akale ndikuwongolera mabatire ndi charger yosagwirizana ndi kutulutsa kuti muwongolere magwiridwe antchito ndi moyo wa batri.
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.
