Chiyambi:
Kuyambira polowa mumsika,Mabatire a Lithiamuakhala akugwiritsidwa ntchito kwambiri chifukwa cha moyo wawo wautali, mphamvu zambiri, komanso zopanda memory. Mukamagwiritsa ntchito kutentha pang'ono, mabatire a lirium-ion amakhala ndi mavuto monga mphamvu yotsika, yodziwikiratu, kuthamanga koonekeratu, komanso kuyikako lithium lini. Komabe, monga momwe munda wagwiritsidwira ntchito ukukulirakulira, zopinga zomwe zimabweretsedwa ndi kutentha kwamphamvu kwambiri kwa mabatire a lithiamu-ion zikuchulukirachulukira. Tiyeni tiwone zifukwa ndikufotokozera momwe angagwirire ntchito mabatire a Lithiamu molondola nthawi yozizira?
Zokambirana pazomwe zimakhudza kutentha kochepa kwa mabatire a lithiamu
1. Mphamvu ya electrolyte
Ma electrolyte ali ndi vuto lalikulu kwambiri pa kutentha kochepa kwaMabatire a Lithiamu. Kuphatikizika ndi ma descoochemical katundu wa electrolyte amakhala ndi chofunikira kwambiri pa betri. Vutoli lomwe layang'aniridwa ndi kutentha kwa batri pamtunda wochepa ndikuti magetsi a electrolyte adzakula, liwiro la ion limachepetsa kuthamanga kwa magetsi, motero batire lidzathetsedwa kwambiri komanso kuwononga mphamvu. Makamaka akamalipiritsa kutentha kochepa, ithiamu ion kumapanga mosavuta kugwirizanitsa a lithiamu pamtunda wa electrode, ndikupangitsa kulephera kwa batri.
2. Mphamvu za zida zamagetsi zamagetsi
- Colarte polarization ndiofunika pakutentha kwambiri-kutentha kwambiri ndikuchichotsa, komanso lithillic ithiric imayikidwa pamwamba pa electrode yoyipa. Zomwe zimachitika chifukwa cha methiallic lithium ndi electrolyte nthawi zambiri sizichititsa;
- From a thermodynamic point of view, the electrolyte contains a large number of polar groups such as CO and CN, which can react with the negative electrode material, and the SEI film formed is more susceptible to low temperature;
- Zimakhala zovuta kuti kaboni ikhale yopanda ma elesiting a lithiamu pa kutentha kochepa, ndipo pali ma asymetry pakubweza ndikubwezeretsanso.
Momwe mungagwiritsire mabatire a Lithiamu molondola nthawi yozizira?
1. Osagwiritsa ntchito mabatire a lithium pamtunda wotsika
Kutentha kumakhudza kwambiri mabatire a lithiamu. Kutsitsa kutentha, kutsitsa ntchito kwa mabatire a lifium, omwe amabweretsa mwachindunji pakuchepetsa kwakukulu pakubweza. Nthawi zambiri, kutentha kogwira ntchito kwaMabatire a Lithiamuili pakati -20 madigiri ndi 60 madigiri.
Matenthedwe akakhala pansi pa 0 ℃, samalani kuti musawalipire panja. Titha kutenga batri m'nyumba kuti mulipire (chotani, onetsetsani kuti mwakhala kutali ndi zida zoyaka !!!). Kutentha kumakhala pansi - 20 ℃, batire limangolowa madontho ndipo simungagwiritsidwe ntchito bwino.
Chifukwa chake, makamaka ogwiritsa ntchito m'malo ozizira kumpoto, ngati palibe vuto lokhalitsa, gwiritsani ntchito kutentha kotsalira, ndikuisunga padzuwa atayikiridwa kuti muchepetse kuchuluka kwa chipika cha lithiamu.
2. Khalani ndi chizolowezi cholipirira monga momwe mumagwiritsira ntchito
M'nyengo yozizira, mphamvu ya batri ili yotsika kwambiri, tiyenera kuimba mlandu munthawi ndikupanga chizolowezi chabwino cholipirira mukamagwiritsa ntchito. Kumbukirani, musayerekezere mphamvu ya batri nthawi yozizira molingana ndi moyo wabwino batri.
M'nyengo yozizira, ntchito yaMabatire a LithiamuAmachepetsa, zomwe zimayambitsa mosavuta komanso mopitirira malire, zomwe zingakhudze moyo wa batri kapena kuchititsa ngozi zoyaka. Chifukwa chake, nthawi yozizira, muyenera kulipira chidwi cholipiritsa pang'ono ndi pang'ono. Makamaka, musayike galimoto kwa nthawi yayitali mukamalipiritsa kuti mupewe kuchita zambiri.
3. Musakhale osalipirira. Kumbukirani kuti musalipire kwa nthawi yayitali.
Osayitanitsa galimoto kwa nthawi yayitali kuti musangalale. Ingosungeni zikangoyimbidwa mlandu. Chilengedwe cholipirira nthawi yozizira sichikhala chotsika kuposa 0 ℃. Mukamalipira, musasiye kutali kwambiri kuti mupewe ngozi zadzidzidzi ndikuthana nawo munthawi yake.
4. Gwiritsani ntchito chomangira chodzipereka kwa mabatire a lithiamu pakulipira.
Msika uli ndi zodzaza zapamwamba kwambiri. Kugwiritsa ntchito ndalama zochepa kwambiri kumapangitsa kuwonongeka kwa batri ndipo kumayambitsa moto. Musagule zinthu zamtengo wapatali zotsika mtengo komanso zosasungidwa, zisagwiritse ntchito mabatire a acibedi acid; Ngati chovala chanu sichingagwiritsidwe ntchito, siyani kugwiritsa ntchito nthawi yomweyo, ndipo musataye chithunzi chaching'ono.
5. Yang'anirani moyo wa batri ndikusintha nthawi
Mabatire a Lithiamukhalani ndi moyo. Makonda osiyanasiyana ndi mitundu imakhala ndi moyo wosiyanasiyana. Kuphatikiza apo, chifukwa cha kugwiritsa ntchito mosayenera tsiku ndi tsiku, moyo wa batri umachokera kwa miyezi ingapo mpaka zaka zitatu. Ngati galimoto imataya mphamvu kapena moyo wa batri ndi zazifupi, chonde funsani ogwira ntchito ya batiri ya Lithiamu nthawi kuti mugwire.
6. Siyani mphamvu yozizira
Pofuna kugwiritsa ntchito galimoto nthawi zonse chaka chamawa, ngati batire siligwiritsidwa ntchito kwa nthawi yayitali, kumbukirani kuwongolera mpaka 50% -80%, chotsani nthawi zonse, pafupifupi kamodzi pamwezi. Chidziwitso: Batri iyenera kusungidwa m'malo owuma.
7. Ikani batire molondola
Osamiza betri m'madzi kapena kunyowa; Osasunga batire kuposa 7 zigawo 7, kapena kulowera ku batri.
Mapeto
Pa -20 ℃, kutulutsa kwa mabatire a lithiamu ndi pafupifupi 31.5% ya izi kutentha. Kutentha kwa mabatire achikhalidwe ali pakati pa -20 ndi + 55 ℃. Komabe, m'magawo a Aerospace, makampani ankhondo, magalimoto amagetsi, ndi zina. Chifukwa chake, kukonza njira yotsika-kutentha kwa mabatire a litimu ndi yofunikira kwambiri. Zachidziwikire,batiri litalimuMakampani amayamba kukhala akukula nthawi zonse, ndipo asayansi akupitiliza kuphunzira mabatire a lifimoni omwe angagwiritsidwe ntchito pamatenthedwe otsika kuti athetse mavuto.
HERTEC Mphamvu ndi mnzanu wodalirika pazinthu zopangira batri. Ndi chidwi chathu chofufutira ndi chitukuko, kuphatikiza ndi zinthu zambiri zowonjezera batri, timapereka njira imodzi yothetsera mavuto omwe akwaniritsa malonda. Titha kusintha matrate a lithum pazochitika zosiyanasiyana zamakasitomala. Ngati mukufuna kukweza batri yanu kapena kukhazikitsa gulu loteteza, chonde lemberani.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, chonde musazengereze kuteroFikirani kwa ife.
