Customization Service
Since we control every step of production — from cell matching to final pack assembly — we can customize voltage, discharge rate, and connector types flexibly.When placing an order, you can specify the Plug Type and C-rate.
High-C production workshop
-
Cell Formation & Aging System
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. -
Ultra-Low Humidity Dry Room
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.
-
Electrode Consistency & Calendering Control
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.
