46135 Battery Cell For Electric Vehicle | CNS BATTERY
The electric vehicle revolution demands powertrain solutions that balance energy density, thermal management, and structural integrity. The 46135 battery cell represents the next evolution in cylindrical lithium-ion technology, offering manufacturers a scalable platform for high-performance EV applications. As a leading battery manufacturer, CNS BATTERY delivers 46135 cells engineered to meet stringent international compliance standards while maximizing operational efficiency.
Technical Architecture of the 46135 Cylindrical Cell
The 46135 designation follows IEC 61960 nomenclature: 46mm diameter and 135mm height. This form factor provides approximately 30-36 Ah capacity with energy density reaching 280-320 Wh/kg depending on cathode chemistry (NCM 811 or NCA variants). The larger format compared to 2170 or 18650 cells reduces pack-level component count by nearly 80%, simplifying thermal management systems and lowering manufacturing costs.
Key Performance Parameters:
| Parameter | Specification |
|---|---|
| Nominal Capacity | 30,000-36,000 mAh |
| Nominal Voltage | 3.6-3.7V |
| Max Continuous Discharge | 3-5C (90-180A) |
| Peak Discharge | 10C (300A+) |
| Cycle Life | 2,000-4,000 cycles @80% DOD |
| Operating Temperature | -20°C to 60°C |
| Internal Resistance | ≤8 mΩ |
The all-tab (tabless) design minimizes electron travel distance, reducing internal resistance and heat generation during high-rate discharge. This architecture enables superior thermal dissipation compared to traditional tab configurations, critical for maintaining cell integrity under demanding EV operating conditions.
Validation Testing Protocols
CNS BATTERY subjects every 46135 cell batch to comprehensive validation following international standards:
1. UN38.3 Transportation Safety Testing
Mandatory for global logistics, this certification encompasses eight critical tests: altitude simulation, thermal cycling, vibration, shock, external short circuit, impact, overcharge, and forced discharge. Compliance ensures safe air, sea, and ground transportation across all jurisdictions.
2. IEC 62660 Performance Validation
This standard evaluates capacity retention, power capability, and cycle life under controlled conditions. Our cells demonstrate less than 20% capacity degradation after 2,000 full cycles at 25°C ambient temperature.
3. Thermal Abuse Testing
Cells undergo heating, nail penetration, and crush testing to verify thermal runaway resistance. Advanced ceramic-coated separators and electrolyte additives provide additional safety margins exceeding regulatory minimums.
4. Regional Certification Requirements
- European Union: CE marking with compliance to EU Battery Regulation 2023/1542, including carbon footprint documentation and recycled content declarations
- United States: UL 2580 certification for EV battery systems, plus UN38.3 for transportation
- North America: Additional CSA Group validation for Canadian market access
Geographic Compliance & Market Adaptation
