Ukuveliswa: uhlalutyo lobugcisa bepeyinti

Njengoko sonke siyazi, i-electrode engafanelekanga yebhetri ye-lithium yi-aluminium foil, kunye ne-electrode engafanelekanga i-copper foil. Emva kokugquma, i-coil ye-anode kunye ne-anode coil zenziwa ukuqhutyelwa phambili. Umgangatho we-electrode umisela imisebenzi ethile yebhetri, kwaye ukugquma kwe-substrate yinxalenye ebaluleke kakhulu kuyo yonke inkqubo yokuvelisa ibhetri!

Ukusuka kwindlela yokwaleka yediphu yoqobo, eyona nto iphambili enamacala amabini igqithiselwe ukuphucula umgangatho kunye netafile yokusebenza kwengubo. Ezinye iiyunithi zamandla ezoqoqosho zasekhaya, ukuze zenze ibhetri yelithium isebenze, yazise isixa esikhulu somatshini obiza imali eninzi wePole piece.

Inkqubo yokwambathisa jikelele: Isixhobo sokukhupha umatshini wokugquma sinxibe i-substrate (ifoyile). Umaleko wokuqala kunye nenqanaba lokugqibela le-substrate lidityaniswe liqonga lokuqhawula ukwenza umcu oqhubekayo, othi ke utyiswe kwisixhobo sokugquma ngesixhobo sohlengahlengiso loxinzelelo kunye nesixhobo sokulungisa esisebenzayo ngesixhobo soxinzelelo. Ngokomlinganiselo wokugquma kunye nobude besithuba esingenanto, isiqwenga senziwe kwisixhobo sokugquma. Kwimibhobho ephindwe kabini, ubude be-pre-coating kunye ne-coating blanks zilandelwa ngokusebenzayo. I-electrode emanzi egqunyiweyo ithunyelwa kwi-slot ekruqulayo ukuze ikruquke, kwaye iqondo lobushushu elikruqulayo limiselwe ngokwesantya sokugquma kunye nobukhulu bokugquma. Emva kokulungiswa koxinzelelo lwepleyiti edikayo kunye nokulungiswa okusebenzayo, inkqubo elandelayo yokujika iyaqhutywa.

Pole piece ukutyabeka ubukhulu, ubuninzi ukutyabeka, umthwalo owomileyo. Ukwemba impembelelo yomoya oshushu ngoku kusetyenziswa ngokubanzi. I-substrate ye-electrode enhle i-aluminium foil, eneempawu zeekhemikhali ezisebenzayo kakhulu kwaye i-oxidized ngokulula. Kwinkqubo yokwenza i-aluminium foil, ifilimu encinci ye-oxide yenziwe ukukhusela i-oxidation eyongezelelweyo ye-aluminium foil. Ngenxa yokuba ifilimu ye-oxide incinci, i-porous kwaye ithambile, inokusebenza kakuhle kwe-adsorption, kodwa ukushisa okuphezulu kunye nomswakama ophezulu kuya kutshabalalisa ifilimu ye-oxide kwaye ikhawulezise ukusabela kwe-oxidation. Eyona nto ibalulekileyo ngoku yindlela yokwaleka kwicala elinye. Ngakolunye uhlangothi, xa i-coat yokuqala ibonakaliswe ngokupheleleyo emoyeni, i-coating (ioli), umoya owomileyo oshushu malunga ne-130 ° C, ukuba umxholo wamanzi womoya oshushu awukho Ulawulo oluluncedo luya kongeza i-aluminium oxide foil kunye kuchaphazela izinto ze-anode kunye neglue ye-aluminium foil, kunye nokwenza amaconsi amanzi kwiimeko ezinzima.

Abavelisi bentlangano yaseMelika kunye neJapan baye baphuhlisa iteknoloji yokwaleka emacala amabini kwi-single-layer coating function kunye ne-aluminium foil oxidation, eyisombulula ngokupheleleyo ingxaki ye-aluminium foil coating oxidation. Nangona kunjalo, ixabiso lomatshini wokugquma wamacala amabini alifikeleleki ngabavelisi bebhetri abaqhelekileyo.
