Nchiyani chimayambitsa mabatire a lithiamu kuyaka moto ndikuphulika?

Chiyambi:

Mabatire a lithiamuzakhala gawo lofunikira pa moyo wathu watsiku ndi tsiku, kupatsa mphamvu chilichonse kuchokera ku mafoni a m'manja ndi laputopu kupita ku magalimoto amagetsi ndi machitidwe osungira mphamvu. Mabatire a lithiamu amagwiritsidwa ntchito kwambiri, koma pakhala pali moto ndi kuphulika, zomwe, ngakhale kuti ndizosowa, zakhala zikudandaula za chitetezo chawo. Kumvetsetsa zinthu zomwe zingayambitse zochitika zoterezi ndizofunikira kuti mutsimikizire kuti mabatire a lithiamu akugwiritsidwa ntchito motetezeka komanso odalirika.

Kuphulika kwa batri la lithiamu ndi vuto lalikulu la chitetezo, ndipo zomwe zimayambitsa zochitika zimakhala zovuta komanso zosiyana, makamaka kuphatikizapo zamkati ndi zakunja.

Zinthu zamkati

Dera lalifupi lamkati

Kusakwanira kokwanira kwa elekitirodi: Pamene mphamvu yolakwika ya elekitirodi yabwino ya batire ya lithiamu sikukwanira, maatomu a lithiamu omwe amapangidwa panthawi yolipiritsa sangalowetsedwe mu gawo la interlayer la negative elekitirodi graphite, ndipo amatsika pamwamba pa electrode yoyipa. kupanga makhiristo. Kudzikundikira kwa nthawi yayitali kwa makristalowa kungayambitse kufupika, selo la batri limatuluka mofulumira, limatulutsa kutentha kwakukulu, limawotcha diaphragm, ndiyeno limayambitsa kuphulika.

Mayamwidwe amadzi a electrode ndi ma electrolyte reaction: Electrode ikayamwa madzi, imatha kuchitapo kanthu ndi electrolyte kuti ipange zotupa za mpweya, zomwe zitha kuyambitsa mabwalo amkatikati.

Mavuto a Electrolyte: Ubwino ndi magwiridwe antchito a electrolyte palokha, komanso kuchuluka kwamadzi omwe amabayidwa panthawi ya jakisoni omwe sakukwaniritsa zofunikira, zingakhudze chitetezo cha batri.

Zowonongeka pakupanga: Zonyansa, fumbi, ndi zina zambiri zomwe zingakhalepo panthawi yopangira batire zingayambitsenso mabwalo ang'onoang'ono.

Kuthamanga kwamafuta

Pamene kuthawa kwa matenthedwe kumachitika mkati mwa batri ya lithiamu, kuphulika kwa mankhwala kudzachitika pakati pa zipangizo zamkati za batri, ndipo mipweya yoyaka moto monga hydrogen, carbon monoxide, ndi methane idzapangidwa. Zochita izi zidzatsogolera ku machitidwe atsopano a mbali, kupanga chizungulire choyipa, kuchititsa kutentha ndi kupanikizika mkati mwa batri kukwera kwambiri, ndipo pamapeto pake kumayambitsa kuphulika.

Kuchulukitsa kwa nthawi yayitali kwa batri

Pazifukwa zolipiritsa kwa nthawi yayitali, kuchulukirachulukira komanso kupitilira apo kungayambitsenso kutentha kwambiri komanso kuthamanga kwambiri, zomwe zimatha kuyambitsa ngozi.

Zinthu zakunja

Dera lalifupi lakunja

Ngakhale mabwalo achifupi akunja samayambitsa kutha kwa batri, mafupi akunja akutali angapangitse kuti malo olumikizirana azitha kuyaka, zomwe zingayambitse zovuta zachitetezo.

Kutentha kwakunja kwapamwamba

Pansi pa kutentha kwakukulu, chosungunulira cha electrolyte cha mabatire a lithiamu chimatuluka mofulumira, zipangizo za electrode zimakula, ndipo kukana kwa mkati kumawonjezeka, zomwe zingayambitse kutayikira, maulendo afupikitsa, ndi zina zotero, zomwe zimayambitsa kuphulika kapena moto.

Kugwedezeka kwa makina kapena kuwonongeka

Mabatire a lithiamu akagwidwa ndi kugwedezeka kwamphamvu kapena kuwonongeka panthawi yoyendetsa, kugwiritsidwa ntchito kapena kukonza, diaphragm kapena electrolyte ya batri ikhoza kuwonongeka, zomwe zimapangitsa kuti pakhale kukhudzana kwachindunji pakati pa zitsulo za lithiamu ndi electrolyte, zomwe zimayambitsa kuphulika, ndipo pamapeto pake zimabweretsa kuphulika kapena kuphulika. moto.

Kulipira vuto

Kuchulukirachulukira: Dera lodzitchinjiriza silingathe kuwongolera kapena kabati yodziwikiratu ndiyosokonekera, zomwe zimapangitsa kuti magetsi azikwera kwambiri kuposa mphamvu yamagetsi ya batire, zomwe zimapangitsa kuwonongeka kwa electrolyte, chiwawa mkati mwa batire, komanso kukwera mwachangu mkati. kuthamanga kwa batri, komwe kungayambitse kuphulika.

Kuchulukirachulukira: Kuchulukirachulukira kwapano kungapangitse ma ion a lithiamu asakhale ndi nthawi yolowera mumtengowo, ndipo chitsulo cha lithiamu chimapangidwa pamwamba pamtengowo, kulowa mkati mwa diaphragm, kupangitsa kuti pakhale kufupi kwafupi pakati pa mitengo yabwino ndi yoyipa ndi kuphulika. .

Mapeto

Zomwe zimayambitsa kuphulika kwa batri ya lithiamu zimaphatikizapo maulendo amkati amkati, kuthawa kwa kutentha, kuwonjezereka kwa nthawi yaitali kwa batri, maulendo ang'onoang'ono akunja, kutentha kwa kunja, kugwedezeka kwa makina kapena kuwonongeka, mavuto olipira, ndi zina. Chifukwa chake, mukamagwiritsa ntchito ndikusunga mabatire a lithiamu, ndikofunikira kutsatira mosamalitsa malamulo otetezedwa kuti mutsimikizire chitetezo ndi bata la batri. Nthawi yomweyo, kulimbikitsa kuyang'anira chitetezo ndi njira zodzitetezera ndizofunikanso kuti tipewe kuphulika kwa batri la lithiamu.

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.
