Electrodeposited (ED)foil ọla kọpabụ ọkpụkpụ a na-adịghị ahụ anya nke ngwá electronic ọgbara ọhụrụ. Profaịlụ ya dị oke mkpa, ductility dị elu, yana ezigbo omume na-eme ka ọ dị mkpa na batrị lithium, PCBs na ngwa eletrọnịkị na-agbanwe agbanwe. N'adịghị kampịakọta ọla kọpa, nke na-adabere na nrụrụ igwe,ED ọla kọpa foila na-emepụta site na ntinye nke electrochemical, nweta njikwa ọkwa atomic na nhazi ọrụ. Isiokwu a na-ekpughe nkenke n'azụ mmepụta ya na otú usoro mmepụta ihe na-agbanwe ụlọ ọrụ.
I. Mmepụta ọkọlọtọ: Nkenke na Injinia Electrochemical
1. Nkwadebe Electrolyte: Usoro Nano kachasị mma
Electrolyte isi mejupụtara sulfate ọla kọpa dị elu (80-120g/L Cu²⁺) na sulfuric acid (80–150g/L H₂SO₄), yana gelatin na thiourea agbakwunyere na ọkwa ppm. Sistemu DCS dị elu na-ejikwa okpomọkụ (45-55°C), ọnụego eruba (10-15 m³/h), na pH (0.8-1.5) na nkenke. Ihe mgbakwunye na-adaba na cathode iji duzie nhazi ọka nano-larịị ma gbochie ntụpọ.
2. Nkwụnye ego nke ọma: Atọmịk nkenke n'omume
N'ime sel electrolytic nwere titanium cathode mpịakọta (Ra ≤ 0.1μm) na ndu alloy anodes, 3000-5000 A / m² DC ugbu a na-eme ka ntinye ọla kọpa ion na elu cathode na (220). A na-enyocha ọkpụrụkpụ foil (6-70μm) nke ọma site na ọsọ mpịakọta (5-20 m/min) yana mgbanwe dị ugbu a, na-enweta njikwa ọkpụrụkpụ ± 3%. Foil kacha dị gịrịgịrị nwere ike iru 4μm—1/20th nke ọkpụrụkpụ ntutu mmadụ.
3. Ịsacha: Ihe dị ọcha dị ọcha na mmiri dị ọcha
Usoro ntughari nke okpukpu atọ na-ewepụ ihe niile fọdụrụnụ: Nkeji 1 na-eji mmiri dị ọcha (≤5μS / cm), Nkeji 2 na-emetụta ebili mmiri ultrasonic (40kHz) iji kpochapụ ihe ndị na-ahụ maka ihe ndị dị ndụ, na ọkwa 3 na-eji ikuku dị ọkụ (80-100 ° C) maka ikpochapụ enweghị ntụpọ. Nke a na-ebutefoil ọla kọpanwere ọkwa oxygen <100ppm na sulfur residues <0.5μg/cm².
4. Slitting na nkwakọ ngwaahịa: nkenke na Final Micron
Igwe na-agbapụ ọsọ dị elu nwere njikwa ihu laser na-eme ka ohere obosara dị n'ime ± 0.05mm. Nkwakọ ngwaahịa mgbochi oxidation na-egosi iru mmiri na-echekwa ịdịmma elu n'oge njem na nchekwa.
II. Nhazi ọgwụgwọ dị n'elu: Imepe ụlọ ọrụ akọwapụtara nke ọma
1. Ọgwụgwọ Roughening: Micro-anchoring maka nkwalite nkwalite
Ọgwụgwọ Nodule:Pulse plating na CuSO₄-H₂SO₄-As₂O₃ ngwọta na-emepụta 2-5μm nodules na foil elu, na-eme ka ike nkedo ruo 1.8-2.5N/mm-dị mma maka bọọdụ sekit 5G.
Ọkpụkpọ-ọnụ kacha elu:Ụmụ irighiri ọla kọpa micro na nano na-abawanye ebe elu site na 300%, na-eme ka adhesion slurry na anodes batrị lithium site na 40%.
2. Nkwadebe na-arụ ọrụ: Armor-Scale Armor for Inteability
Zinc/Tin Plating:Igwe igwe 0.1-0.3μm na-agbatị nguzogide nnu nnu site na awa 4 ruo 240, na-eme ka ọ bụrụ ihe aga-aga maka taabụ batrị EV.
Nickel-Cobalt Alloy mkpuchi:Nano-grain layers (≤50nm) na-enweta ike HV350, na-akwado mkpụrụ osisi bendable maka ekwentị ndị a na-emegharị emegharị.
3. Nguzogide oke okpomọkụ: Ịlanahụ oke
Sol-gel SiO₂-Al₂O₃ mkpuchi (100-200nm) na-enyere foil aka iguzogide oxidation na 400 ° C (oxidation <1mg/cm²), na-eme ka ọ bụrụ egwuregwu zuru oke maka sistemụ ikuku ikuku.
III. Inye ikike nke nnukwu ụlọ ọrụ atọ
1. Batrị Ike Ọhụrụ
CIVEN METAL's 3.5μm foil (≥200MPa tensile, ≥3% elongation) na-abawanye njupụta batrị 18650 site na 15%. Omenala foil gbawara agbawa (30-50% porosity) na-enyere aka igbochi nhazi lithium dendrite na batrị steeti siri ike.
2. PCB dị elu
Obere profaịlụ (LP) nwere Rz ≤1.5μm na-ebelata mfu mgbaàmà na bọọdụ ebili mmiri 5G site na 20%. Profaịlụ dị ala (VLP) nwere mmecha a na-emegharị azụ (RTF) na-akwado ọnụego data nke 100Gb/s.
3. Eletrọnịkị na-agbanwe agbanwe
AnneededED ọla kọpa foil(≥20% elongation) ejiri ihe nkiri PI kpuchie ihe karịrị 200,000 bends (1mm radius), na-eme dị ka “ọkpụkpụ na-agbanwe agbanwe” nke wearables.
IV. CIVEN METAL: Onye ndu nhazi na ED Copper Foil
Dị ka ụlọ ike dị jụụ na foil ọla kọpa ED,CIVEN METALemebela usoro nrụpụta agile, modular:
Ọbá akwụkwọ Nano-agbakwunye:Ihe karịrị ngwakọta mgbakwunye 200 ahaziri maka ike tensile dị elu, elongation na nkwụsi ike ọkụ.
Mmepụta foil na-eduzi AI:Oke AI-kachasị mma na-eme ka o doo anya ± 1.5% ọkpụrụkpụ ziri ezi na ≤2I flatness.
Ebe Ngwọta Elu:Ahịrị 12 raara onwe ya nye na-enye nhọrọ 20+ nwere ike ịhazi ya (roughening, plating, covers).
Ọnụ ihe ọhụrụ:Iweghachi ihe mkpofu n'ime ahịrị na-akwalite ojiji ọla kọpa raw ruo 99.8%, na-ebelata ọnụ ahịa foil omenala site na 10-15% n'okpuru nkezi ahịa.
Site na njikwa lattice atomịk ruo n'iji nlegharị anya arụmọrụ nnukwu,ED ọla kọpa foilna-anọchi anya oge ọhụrụ nke injinịa ihe. Ka mgbanwe zuru ụwa ọnụ n'ebe eletrịkị na ngwaọrụ smart na-esiwanye ike,CIVEN METALna-eduga ụgwọ ahụ na ụdị “atomiki nkenke + ngwa ọhụrụ” ya - na-eme ka nrụpụta China dị elu na-aga n'elu nke oke ọnụ ahịa zuru ụwa ọnụ.
