Al-Zn-In alloy anodes engineered to exceed the Chinese national standard by 200–300 A·h/kg. Electrochemical capacity held above 2700 A·h/kg — current efficiency ≥ 95 %. Backed by a written double-refund guarantee.
View Performance DataAll five alloy series are produced in strict accordance with GB/T 4948-2025. Every ingot is traceable to the melt chemistry, with full per-batch inspection reports on request.
Fe, Cu, Si held well below the GB upper limits — essential for stable electrochemical performance.
Every batch shipped with a complete mill certificate and chemistry report, ingot-traceable.
Dual accreditation — CMA and CNAS. Independent verification on request before shipment.
GB/T 4948 requires only 2600 A·h/kg at the peak (Type 4). CathPro commits all five alloy types at ≥ 2700 A·h/kg with current efficiency ≥ 95 % — substantially above national benchmark on every measured axis.
| Type | GB Capacity (min) | CathPro Capacity | GB Efficiency (min) | CathPro Efficiency | Open-circuit (V) |

| Type 1 | ≥ 2500 A·h/kg | ≥ 2700 A·h/kg | ≥ 85 % | ≥ 95 % | −1.18 ~ −1.10 |
| Type 2 | ≥ 2400 A·h/kg | ≥ 2700 A·h/kg | ≥ 80 % | ≥ 95 % | −1.18 ~ −1.10 |
| Type 3 | ≥ 2500 A·h/kg | ≥ 2700 A·h/kg | ≥ 85 % | ≥ 95 % | −1.18 ~ −1.10 |
| Type 4 | ≥ 2600 A·h/kg | ≥ 2700 A·h/kg | ≥ 90 % | ≥ 95 % | −1.18 ~ −1.10 |
| Type 5 | ≥ 2500 A·h/kg | ≥ 2700 A·h/kg | ≥ 85 % | ≥ 95 % | −1.18 ~ −1.10 |
Every supply contract carries a written performance guarantee backed by independent third-party verification. If the delivered product fails the committed specification under CMA / CNAS testing, CathPro reimburses double the prepayment.
"CathPro warrants that all supplied aluminum anode products meet the committed specifications (capacity ≥ 2700 A·h/kg, current efficiency ≥ 95 %). Should CMA- or CNAS-accredited third-party testing return values below the commitment, CathPro shall reimburse the buyer at twice the prepaid amount."
