custom newyenk battery

Through tightly controlled formation and aging processes under stable temperature conditions, we stabilize the SEI layer, screen early failures, and ensure consistent internal resistance across cells.

Critical processes are carried out in an ultra-dry environment (≤1% RH, dew point ≤ −40°C),ensuring low internal resistance, consistency, and stable high-rate performance.

High-rate performance depends on consistency.

By tightly controlling coating thickness and calendering density, we ensure uniform current paths and low impedance across cells, enabling stable and repeatable high C-rate performance.
