Dab tsi yog cov ntawv siv dual ntawm txhuas ntawv ci hauv cov hlwb thiab capacitors?
In lithium-ion cells, it serves as cathode current collector (10-20μm thickness) with>=99.5% purity. Rau capacitors, ultra - daim ntawv ci (5-8μm) Enaber muaj peev xwm siab nyob hauv cov khoom ntawm cov kab mob. Cov ntaub ntawv ductility tso cai nruj rau ob qho tib si cylindrical thiab capactrator cov ntsiab lus. Cov kev kho cov npoo sib txawv txawv - capacitors yuav tsum tau siab dua roughness (0.4-0.6.6μ3μ mtrolyte ntub dej. Aluminium lub qhov rais ruaj khov (-1.0 rau {{} v vs nws) ua rau nws zoo tagnrho rau ob daim ntawv thov.
Yuav ua li cas ua ntawv ci yuav tsum sib txawv ntawm lub zog capacitors thiab lub zog?
Power capacitors demand 6-8μm foil with 300-350MPa tensile strength for high ripple current endurance. Energy cells prioritize 15-20μm thickness for long cycle life stability. Capacitor foils require controlled etching (20-50μm pit depth) to increase effective surface area. Battery foils need smoother surfaces (0.1-0.2μm Ra) for uniform coating adhesion. High-voltage capacitors (>100V) Siv cov ntawv tshwj xeeb ntawm cov ntawv ci nrog 0.1% ntxiv ntxiv.
Dab tsi ua qauv kev tswj hwm txhuas cov ntawv ci rau cov ntawv thov no?
Iec 62391-2 Specifies captor ntawv kub xws li DC tiv taus (<0.1Ω·cm²). UL 810A requires foils to withstand 150°C for 1000h in capacitor testing. Battery foils follow GB/T 3198 with pinhole limits (<3/m² for premium grade). JIS H4160 defines mechanical properties for Japanese capacitor manufacturers. ASTM B479 regulates foil thickness tolerance within ±3% for US market.
Vim li cas ntawv ci kom huv siab tseem ceeb rau capacitor kev ua tau zoo?
Residual oils >50mg/m² can cause electrolyte decomposition at high frequencies. Particle contaminants >5μm Tej zaum yuav ua tsis tau microschocic luv luv. Ntiv tes cov khoom seem nce ntxiv ERR (sib npaug series tiv taus) los ntawm 10-15%. Cov kev ua kom huv huv<100 particles/ft³ during foil slitting. Plasma cleaning achieves surface carbon content <0.1 atomic% pre-coating.
Cov thev naus laus zis dab tsi yog thawb cov ciaj kev ua tau zoo?
