Chiyambi:
Mabatire a LithiumZakhala gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku, kupatsa mphamvu chilichonse kuyambira mafoni a m'manja ndi ma laputopu mpaka magalimoto amagetsi ndi makina osungira mphamvu. Mabatire a lithiamu amagwiritsidwa ntchito kwambiri, koma pakhala milandu ya moto ndi kuphulika, zomwe, ngakhale sizichitika kawirikawiri, zadzetsa nkhawa za chitetezo chawo. Kumvetsetsa zinthu zomwe zingayambitse zochitika zotere ndikofunikira kwambiri kuti zitsimikizire kuti mabatire a lithiamu akugwiritsidwa ntchito bwino komanso modalirika.
Kuphulika kwa mabatire a lithiamu ndi vuto lalikulu la chitetezo, ndipo zifukwa zake zimakhala zovuta komanso zosiyanasiyana, makamaka kuphatikizapo zinthu zamkati ndi zakunja.
Zinthu zamkati
Mkati mwafupikitsa
Kusakwanira kwa ma electrode oipa: Ngati mphamvu ya ma electrode oipa ya ma electrode abwino a batri ya lithiamu sikokwanira, maatomu a lithiamu omwe amapangidwa panthawi yochaja sangalowe mu kapangidwe ka interlayer ka graphite ya ma electrode oipa, ndipo adzagwa pamwamba pa ma electrode oipa kuti apange ma crystals. Kusonkhanitsa kwa ma crystals amenewa kwa nthawi yayitali kungayambitse short circuit, cell ya batri imatuluka mwachangu, imapanga kutentha kwambiri, imatentha diaphragm, kenako imayambitsa kuphulika.
Kuyamwa kwa madzi ndi ma electrolyte: Pambuyo poti electrode yayamwa madzi, imatha kuchitapo kanthu ndi electrolyte kuti ipange ma bulges a mpweya, zomwe zingayambitse ma short circuits amkati.
Mavuto a Electrolyte: Ubwino ndi magwiridwe antchito a electrolyte yokha, komanso kuchuluka kwa madzi omwe amalowetsedwa panthawi yobayira omwe sakwaniritsa zofunikira pa ndondomekoyi, zitha kukhudza chitetezo cha batri.
Zodetsa pakupanga: Zodetsa, fumbi, ndi zina zotero zomwe zingakhalepo panthawi yopanga batri zingayambitsenso ma micro-short circuits.
Kutentha kothamanga
Pamene kutentha kwa mpweya kumachitika mkati mwa batire ya lithiamu, kusintha kwa mankhwala a exothermic kumachitika pakati pa zinthu zamkati mwa batire, ndipo mpweya woyaka monga hydrogen, carbon monoxide, ndi methane udzapangidwa. Kusinthaku kudzayambitsa kusintha kwatsopano, kupanga kuzungulira koopsa, zomwe zimapangitsa kutentha ndi kupanikizika mkati mwa batire kukwera kwambiri, ndipo pamapeto pake kumabweretsa kuphulika.
Kuchaja kwambiri kwa selo ya batri kwa nthawi yayitali
Pa nthawi yayitali yolipiritsa, kudzaza kwambiri ndi kupitirira muyeso kungayambitsenso kutentha kwambiri ndi kupanikizika kwambiri, zomwe zingayambitse ngozi zachitetezo.
Zinthu zakunja
Dera lalifupi lakunja
Ngakhale kuti ma circuit akunja samayambitsa mwachindunji kutentha kwa batri, ma circuit akunja akunja a nthawi yayitali angayambitse malo ofooka olumikizirana mu circuit kuyaka, zomwe zingayambitse mavuto akulu achitetezo.
Kutentha kwakunja
Pansi pa kutentha kwambiri, electrolyte solvent ya mabatire a lithiamu imaphwa mofulumira, zipangizo za electrode zimakula, ndipo kukana kwamkati kumawonjezeka, zomwe zingayambitse kutuluka kwa madzi, ma short circuits, ndi zina zotero, zomwe zimayambitsa kuphulika kapena moto.
Kugwedezeka kwa makina kapena kuwonongeka
Mabatire a lithiamu akagwedezeka kwambiri kapena kuwonongeka panthawi yoyendetsa, kugwiritsa ntchito kapena kukonza, diaphragm kapena electrolyte ya batri ikhoza kuwonongeka, zomwe zimapangitsa kuti lithiamu yachitsulo ndi electrolyte zigwirizane mwachindunji, zomwe zimayambitsa exothermic reaction, ndipo pamapeto pake zimayambitsa kuphulika kapena moto.
Vuto la kulipiritsa
Kuchaja mopitirira muyeso: Dera loteteza silikulamulirika kapena kabati yozindikira silikulamulirika, zomwe zimapangitsa kuti magetsi ochaja akhale akulu kuposa magetsi ovotera a batri, zomwe zimapangitsa kuti ma electrolyte awonongeke, zotsatira zamphamvu mkati mwa batri, komanso kukwera mwachangu kwa kuthamanga kwa mkati mwa batri, zomwe zingayambitse kuphulika.
Mphamvu Yopitirira Muyeso: Mphamvu yowonjezereka yochaja ingapangitse kuti ma ayoni a lithiamu asakhale ndi nthawi yolowera mu pole, ndipo chitsulo cha lithiamu chimapangidwa pamwamba pa pole, kulowa mu diaphragm, zomwe zimapangitsa kuti pakhale njira yofupikitsa pakati pa positive ndi negative pole ndi kuphulika.
Mapeto
Zomwe zimayambitsa kuphulika kwa mabatire a lithiamu zimaphatikizapo ma circuit afupi amkati, kuthamanga kwa kutentha, kudzaza kwambiri kwa selo ya batire kwa nthawi yayitali, ma circuit afupi akunja, kutentha kwakukulu kwakunja, kugwedezeka kapena kuwonongeka kwa makina, mavuto ochaja, ndi zina. Chifukwa chake, mukamagwiritsa ntchito ndikusamalira mabatire a lithiamu, ndikofunikira kutsatira mosamalitsa malamulo ofunikira achitetezo kuti muwonetsetse kuti batire ndi yotetezeka komanso yokhazikika. Nthawi yomweyo, kulimbitsa kuyang'anira chitetezo ndi njira zodzitetezera ndi njira zofunika kwambiri zopewera kuphulika kwa mabatire a lithiamu.
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.
