Poukisa se 1070 papye chwa a dominan pou ityòm-ion batri aktyèl pèseptè?
1070 aliminyòm (99.7% pite) minimize rezistans elektrik ak konduktiviti pi gran pase oswa egal a 62% IACS. Kontni Fe/Si li yo (<0.25% combined) prevents electrochemical side reactions in electrolytes. The foil's typical thickness (10-20μm) balances energy density and mechanical stability. Compared to 1235, 1070 offers 15% lower DC resistivity (2.65μΩ·cm vs 3.1μΩ·cm). These properties collectively enhance charge/discharge efficiency in NMC and LFP batteries.
Kijan tretman sifas 1070 FOIL la optimize pèfòmans batri?
Penti kabòn kondiktè (1-3μm) yo aplike pou diminye enpedans interfacial. Ablasyon lazè kreye 5-10μm mikwo-Grooves pou pi bon adezyon anod anodik. RA FOIL la 0.1-0.3μm brutality sifas anpeche delaminasyon pandan kalandriye electrodes. Kontrèman ak alyaj 8xxx, kouch oksid natif natal 1070 la (<5nm) doesn't require acid pickling pretreatment. These treatments enable >98% inifòmite kouch nan pwodiksyon elektwòd gwo vitès.
Ki pwopriyete mekanik ki fè 1070 apwopriye pou likidasyon batri?
The foil achieves 80-120MPa tensile strength after annealing with 20-30% elongation. Its fracture toughness (KIC ≥18MPa√m) prevents cracking during 500+ winding cycles. Thinner variants (≤12μm) maintain >50N/mm ² rezistans dlo pou prismatik anpile selil. Konpare ak 3003 alyaj, 1070 gen 40% pi ba travay redi to pandan koupe. Karakteristik sa yo satisfè CATL ak sevè estanda tansyon BYD a.
Ki jan 1070 adrese defi tèmik nan vit-chaje pil?
The alloy's thermal conductivity (235W/m·K) dissipates heat from 4C+ charging currents. Its CTE (23.6×10⁻⁶/°C) matches graphite anodes to minimize thermal stress. Special annealing at 280°C stabilizes microstructure against thermal runaway (>200 degre). Kontrèman ak pèseptè kwiv, 1070 pa katalize dekonpozisyon elektwolit nan tan ki wo. Karakteristik sa yo pèmèt operasyon ki estab nan sistèm batri 800V.
Ki sa ki konpansasyon yo pri-pèfòmans ant 1070 ak 1235 pou EVs?
1070 koute 8-12% plis pase 1235 akòz kontwòl pite sevè (99.7% vs 99.35%). Sepandan, li diminye batri rezistans entèn pa 0.5-1mΩ, pwolonje lavi sik pa 15-20%. Pi wo duktilite li yo pèmèt 10% feuilles mens san yo pa konpwomèt sekirite twou. Pou pil solid-eta, chimi sifas ki pi pwòp 1070 la anpeche nucleation dendrite ityòm. Pandan ke 1235 sifizan pou konsomatè elektwonik, 1070 domine pil otomobil-klas.
