Chiyambi:
Batri ya Lithiumndi batire yomwe imagwiritsa ntchito chitsulo cha lithiamu kapena lithiamu ngati zinthu zamagetsi. Chifukwa cha nsanja yamagetsi yayikulu, kulemera kopepuka komanso moyo wautali wa lithiamu, batire ya lithiamu yakhala mtundu waukulu wa batire womwe umagwiritsidwa ntchito kwambiri pazinthu zamagetsi zamagetsi, makina osungira mphamvu, magalimoto amagetsi ndi madera ena. Lero, tiyeni tiwone njira zomaliza zopangira mabatire a lithiamu, Formation-OCV testcapacity-Separation.
Mapangidwe
Kupanga batire ya lithiamu ndi njira yoyamba yolipirira batire pambuyo poti batire ya lithiamu yadzazidwa ndi madzi.
Njirayi imatha kuyambitsa zinthu zomwe zimagwira ntchito mu batri ndikuyambitsabatri ya lithiamuNthawi yomweyo, mchere wa lithiamu umakumana ndi electrolyte kuti upange filimu yolimba ya electrolyte interface (SEI) kumbali ya electrode yoyipa ya batri ya lithiamu. Filimuyi imatha kuletsa kuchitika kwa zotsatira zoyipa, motero kuchepetsa kutayika kwa lithiamu yogwira ntchito mu batri ya lithiamu. Ubwino wa SEI umakhudza kwambiri moyo wa kuzungulira, kutayika kwa mphamvu koyambirira, komanso magwiridwe antchito a mabatire a lithiamu.
Mayeso a OCV
Mayeso a OCV ndi mayeso a voteji yotseguka, kukana kwamkati kwa AC ndi voteji ya chipolopolo cha selo imodzi. Ndi gawo lofunika kwambiri pakupanga batri. Iyenera kukwaniritsa kulondola kwa OCV kwa 0.1mv ndi kulondola kwa voteji ya chipolopolo cha 1mv. Mayeso a OCV amagwiritsidwa ntchito pokonza maselo.
Njira yopangira mayeso a OCV
Mayeso a OCV makamaka amayesa makhalidwe a batri mwa kukanikiza ma probe olumikizidwa ku choyesera magetsi ndi choyesera chamkati chokana makutu abwino ndi oipa a batri yofewa.
Mayeso a OCV omwe alipo pano makamaka ndi mayeso odziyimira pawokha. Wogwira ntchitoyo amaika batire pamanja mu chipangizo choyesera, ndipo chofufuzira cha chipangizo choyeseracho chimakhudzana ndi makutu abwino ndi oipa a batire kuti achite mayeso a OCV pa batire, kenako amatsitsa ndikusintha batireyo pamanja.
Gawo la mphamvu ya batri ya Lithium
Pambuyo pa gulu lamabatire a lithiamuNgakhale kuti kukula kwake ndi kofanana, mphamvu ya mabatire idzakhala yosiyana. Chifukwa chake, ayenera kuyikidwa chaji yonse pa chipangizocho malinga ndi zofunikira, kenako n’kutulutsidwa (kutulutsidwa kwathunthu) malinga ndi mphamvu yomwe yatchulidwa. Nthawi yomwe imatenga kutulutsa batire mochulukirachulukira ndi mphamvu ya kutulutsa ndi mphamvu ya batire.
Bola mphamvu yoyesedwayo ikakwana kapena kupitirira mphamvu yopangidwa, batire ya lithiamu imakhala yoyenerera, ndipo batire yokhala ndi mphamvu yochepa kuposa yomwe idapangidwayo singaganizidwe kuti ndi batire yoyenerera. Njira iyi yosankha mabatire oyenerera kudzera mu kuyesa mphamvu imatchedwa kugawa mphamvu.
Udindo wabatri ya lithiamuKugawa mphamvu sikuti kumangothandiza kuti filimu ya SEI ikhale yokhazikika, komanso kungafupikitse nthawi yomwe imagwiritsidwa ntchito pogawa mphamvu, kuchepetsa kugwiritsa ntchito mphamvu ndikuwonjezera mphamvu zopangira.
Cholinga china cha kugawa mphamvu ndikugawa mabatire m'magulu, kutanthauza kusankha ma monomers omwe ali ndi kukana kwamkati komweko komanso mphamvu yosakanikirana. Pophatikiza, okhawo omwe ali ndi magwiridwe antchito ofanana ndi omwe angapange paketi ya batire.
Mapeto
Pomaliza,batri ya lithiamuwamaliza ntchito zonse za selo ya batri atayang'ana bwino mawonekedwe ake, kupopera ma code a grade, kuyang'ana grade scanning, ndi kulongedza, akuyembekezera kuikidwa mu paketi ya batri.
Ponena za mabatire, ngati muli ndi lingaliro la mabatire a DIY, Heltec imaperekazoyesa mphamvu ya batrikuti tikuthandizeni kumvetsetsa momwe batire yanu imagwirira ntchito ndikuganizira ngati kuli koyenera kupangira paketi ya batire yomwe mukufuna. Timaperekansochoyezera batrikuti musunge mabatire anu akale ndikulinganiza mabatire ndi mphamvu yofanana komanso kutulutsa mphamvu kuti batire ligwire bwino ntchito komanso lizigwira ntchito bwino.
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.
