Yakaiswa Electrode (ED)foil yemhangurandiyo musimboti usingaoneki wemagetsi emazuva ano. Hunhu hwayo hwakatetepa zvikuru, kugona kwayo kuchinjika zvakanyanya, uye kugona kwayo kuchinjika zvakanaka kunoita kuti ive yakakosha mumabhatiri e lithium, maPCB, uye magetsi anochinjika.foiri yemhangura yakakungurutswa, iyo inoenderana nekushanduka kwemuchina,ED foil yemhangurainogadzirwa nekushandisa electrochemical deposition, zvichiita kuti pave nekudzora atomu uye kugadzirisa mashandiro. Chinyorwa chino chinoburitsa pachena kunyatsogadzirwa kwayo uye kuti hunyanzvi hwekugadzira huri kushandura sei maindasitiri.
I. Kugadzirwa Kwakajairwa: Kunyatsorongeka muUinjiniya hweElectrochemical
1. Kugadzirira Electrolyte: Fomura Yakagadziriswa Nano
Electrolyte yebase ine high-purity copper sulfate (80–120g/L Cu²⁺) uye sulfuric acid (80–150g/L H₂SO₄), ine gelatin nethiourea zvakawedzerwa pa ppm levels. Advanced DCS systems dzinodzora tembiricha (45–55°C), flow rate (10–15 m³/h), uye pH (0.8–1.5) nemazvo. Zvinowedzerwa zvinopinda mu cathode kuti zvitungamirire nano-level grain formation uye zvinodzivirira zvikanganiso.
2. Kuiswa kweFoil: Kushanda kweAtomic Precision
Mumasero emagetsi ane titanium cathode rolls (Ra ≤ 0.1μm) uye lead alloy anodes, 3000–5000 A/m² DC current inotyaira copper ion deposition pamusoro pe cathode mu (220) orientation. Ukobvu hwefoil (6–70μm) hunogadziriswa nemazvo kuburikidza nekumhanya kweroll (5–20 m/min) uye kugadziriswa kwecurrent, zvichiita kuti ±3% thinnest control ione. Foil yakatetepa inogona kusvika 4μm—1/20th ukobvu hwebvudzi remunhu.
3. Kugeza: Nzvimbo Dzakachena Zvikuru Nemvura Yakachena
Sisitimu yekusuka tsvina ine matanho matatu inobvisa zvasara zvese: Danho rekutanga rinoshandisa mvura yakachena (≤5μS/cm), Danho rechipiri rinoshandisa mafungu e ultrasonic (40kHz) kubvisa zvisaririra zve organic, uye Danho rechitatu rinoshandisa mhepo inopisa (80–100°C) kuti iome isina mavara. Izvi zvinoguma nefoil yemhanguraine mwero weokisijeni <100ppm uye masara esulfur <0.5μg/cm².
4. Kucheka neKurongedza: Kunyatsoenderana neMicron Yekupedzisira
Michina yekuchekerera inomhanya zvikuru ine laser edge control inoita kuti hupamhi hukwanise kushivirira mukati me ±0.05mm. Kurongedza kwevacuum anti-oxidation ne hunyoro kunochengetedza kunaka kwenzvimbo panguva yekutakura nekuchengetedza.
II. Kugadzirisa Kurapa Kwepamusoro: Kuvhura Kushanda Kwakanangana Neindasitiri
1. Kurapa Kwekukwesha: Kubatanidza Kukurudza Kwekubatanidza Kwakawedzerwa
Kurapa Mapundu:Kuisa mapuroteni muCuSO₄-H₂SO₄-As₂O₃ mhinduro kunogadzira mapundu e2–5μm pamusoro pefoil, zvichivandudza simba rekunamatira kusvika pa1.8–2.5N/mm—zvakanakira mabhodhi e5G circuit.
Kukweshana Kwepamusoro-Peak:Zvidimbu zvemhangura zvidiki-diki uye zvidiki-diki zvinowedzera nzvimbo yepamusoro ne300%, zvichivandudza kunamira kweslurry mu lithium battery anodes ne40%.
2. Kuputira Kunoshanda: Nhumbi dzeMorecular-Scale dzeKugara kwenguva refu
Kuisa Zinc/Tin:Rutivi rwesimbi rwe 0.1–0.3μm runowedzera simba rekudzivirira kupisa munyu kubva pamaawa mana kusvika mazana maviri nemakumi mana, zvichiita kuti rive chinhu chinoshandiswa nema EV battery tabs.
Kupfeka kweNickel-Cobalt Alloy:Matanda e nano-grain akafukidzwa nepulse-plated (≤50nm) anoita kuti HV350 iome, zvichitsigira ma substrates anopetwa emafoni anopetwa.
3. Kuramba Kupisa Kwakanyanya: Kupona Zvakanyanya
Sol-gel SiO₂-Al₂O₃ coatings (100–200nm) inobatsira foil kudzivirira oxidation pa400°C (oxidation <1mg/cm²), zvichiita kuti ikwane zvakakwana kune masisitimu emagetsi emuchadenga.
III. Kupa Simba kuMatunhu Matatu Makuru Eindasitiri
1. Mabhatiri Matsva Esimba
Foil yeCIVEN METAL ye3.5μm (≥200MPa inodhonzwa, ≥3% kureba) inowedzera simba rebhatiri re18650 ne15%. Foil yakaboorwa nemaburi yakagadzirwa (30–50% porosity) inobatsira kudzivirira kuumbwa kwe lithium dendrite mumabhatiri ane mamiriro akasimba.
2. MaPCB Epamusoro
Foil ine chimiro chepasi (LP) ine Rz ≤1.5μm inoderedza kurasikirwa kwechiratidzo mumabhodhi e5G millimeter-wave ne20%. Foil ine chimiro chepasi (VLP) ine reverse-treated finish (RTF) inotsigira data rates ye100Gb/s.
3. Zvigadzirwa zvemagetsi zvinochinjika
YakanamirwaED foil yemhangura(≥20% kureba) yakaputirwa nemafirimu ePI inokwanisa kumirisana nekukombama kunodarika 200,000 (1mm radius), ichishanda se "skeleton inochinjika" yezvipfeko zvinopfekwa.
IV. CIVEN METAL: Mutungamiriri wekugadzirisa zvinhu muED Copper Foil
Semunhu ane simba rakanyarara muED copper foil,Simbi yeCIVENyakavaka sisitimu yekugadzira inochinjika uye ine modular:
Raibhurari yeNano-Additive:Misanganiswa inodarika mazana maviri yekuwedzera yakagadzirirwa simba rakasimba rekusimba, kureba, uye kugadzikana kwekupisa.
Kugadzirwa kweFoil Inotungamirwa neAI:Maparamita akagadziridzwa neAI anoita kuti ukobvu hwe ±1.5% huve hwakarurama uye kuti huve hwakatsetseka kupfuura ≤2I.
Nzvimbo Yekurapa Pamusoro:Mitsetse gumi nemiviri yakatsaurirwa inopa sarudzo dzinopfuura makumi maviri dzinogadziriswa (kukwesha, kuputira, kuputira).
Kugadzira Zvinhu Zvitsva Mumutengo:Kutora marara ari mumutsara kunowedzera kushandiswa kwemhangura isina kugadzirwa kusvika pa99.8%, zvichideredza mitengo yefoil yakagadzirwa ne10–15% pasi peavhareji yemusika.
Kubva pakudzora maatomu kusvika pakugadzirisa mashandiro emacro-scale,ED foil yemhangurainomiririra nguva itsva yeinjiniya yezvinhu. Sezvo shanduko yepasi rose ichienda pakuisa magetsi nemidziyo yakangwara iri kukurumidza,Simbi yeCIVENinotungamira basa iri nemuenzaniso wayo wekuti "atomic precision + application innovation"—ichisundira kugadzirwa kweChina kwepamusoro-soro pamusoro pecheni yemitengo yepasi rose.
