Chifukwa cha kukula kwachangu kwa batire ya lithiamu ion m'mafoni ndi m'magawo ena, magwiridwe ake otsika kutentha sangathe kusinthana ndi nyengo yapadera yotentha kwambiri kapena malo ovuta kwambiri akuwonekera kwambiri. Pa kutentha kochepa, mphamvu yotulutsa mphamvu yogwira ntchito komanso mphamvu yotulutsa mphamvu yogwira ntchito ya batire ya lithiamu ion zidzachepa kwambiri. Pakadali pano, singathe kubwezeretsedwanso pansi pa -10℃, zomwe zimaletsa kwambiri kugwiritsa ntchito batire ya lithiamu ion.
Batire imaopa kwambiri kutentha kochepa, m'malo otentha pang'ono mphamvu ya batire ndi yotsika kuposa mphamvu yanthawi zonse ya kutentha, ngakhale tsopano batire silikukonzedwanso, makamaka m'nyengo yozizira, nthawi ya batire ya magalimoto amagetsi ndi zida zina zanzeru za lithiamu idzachepetsedwa moyenerera, ndipo nthawi ya batire ya lithiamu m'malo otentha pang'ono idzafupikitsidwa kwambiri.
Zotsatira za kutentha kochepa pa mabatire
1. Kutentha kukatsika, liwiro la reaction la electrode limatsikanso. Ngati mphamvu ya batri imakhalabe yofanana ndipo mphamvu yotulutsa imachepa, mphamvu ya batri nayonso imachepa.
2. Pakati pa zinthu zonse zachilengedwe, kutentha kumakhudza kwambiri momwe batire imagwirira ntchito komanso momwe imatulutsira mphamvu. Machitidwe a electrochemical pa elekitirodi kapena malo olumikizirana a electrolyte amakhudzana ndi kutentha kwa malo, ndipo malo olumikizirana a electrodi kapena electrolyte amaonedwa ngati mtima wa batire.
3. kutentha kukakwera mphamvu ya batri ya lithiamu polymer idzakwera;
4. kutentha kumakhudzanso liwiro la kutumiza kwa electrolyte, kutentha kumakwera, kutentha kwa kutumiza kumatsika, kutumiza kumachepa, kuyatsa ndi kutulutsa kwa batri kumakhudzidwanso. Koma kutentha kwambiri, kopitilira madigiri 45 Celsius, kumatha kusokoneza bwino mankhwala mu batri ndikuyambitsa zotsatirapo zoyipa.
Komanso chifukwa cha kutentha kochepa pa batire, opanga mabatire ambiri amphamvu akupanga mabatire otsika kutentha. Nthawi yomweyo, makampani olumikizira mabatire a lithiamu omwe ali pansi pa batire akupanganso malo osungira mabatire otsika kutentha.
Monga kampani yapamwamba ya chigawo, cholumikizira cha batire chotsika kutentha cha Amass chimagwiritsidwa ntchito kwambiri mu zida zosungira mphamvu, zida za m'munda zopopera chipale chofewa, magalimoto amagetsi ndi zida zina zanzeru zoyenda. Kutentha kochepa kumapangitsa kuti chipolopolo cha pulasitiki cha cholumikizira cha batire chikhale chofooka, ndipo kutentha kotsika kwa chipolopolo cha pulasitiki kumakhala kolimba, ndipo chipolopolo cha pulasitiki chikachepa, chipolopolo cha pulasitiki chikagwira ntchito bwino. Cholumikizira cha batire chotsika kutentha cha Amass LC chimagwiritsa ntchito pulasitiki yaukadaulo ya PBT, yomwe ingagwiritsidwe ntchito kutentha kotsika kwa -40℃. Pa kutentha kumeneku, imatha kuwonetsetsa kuti chipolopolo cha pulasitiki cha cholumikizira cha batire sichidzasweka kapena kusweka, ndikuwonetsetsa kuti cholumikizira cha batire chikugwira ntchito bwino.
Makina a LC amagwiritsa ntchito conductor wamkuwa, womwe umatha kuteteza pulasitiki wambiri kutentha kochepa. Kukana kwa bande kumachepa kutentha kukachepa, zomwe zingatsimikizire bwino ubwino wa kukana kochepa komanso kunyamula mphamvu yayikulu ya batire.
Mndandanda wa LC sikuti umangowonjezera mphamvu zamagetsi kudzera mu mkuwa, komanso umawongolera kapangidwe kake ka kukhudzana. Kulumikizana kwamkati kwa korona, kukhudzana katatu, kukana zivomerezi komanso kukana kusweka mwadzidzidzi mukayika, kumathandizira kwambiri moyo wautumiki wa cholumikizira cha batri ya lithiamu.
Kuti mudziwe zambiri zokhudza zolumikizira mabatire, onani https://www.china-amass.net/
