The EVE 46950 cylindrical lithium-ion battery is a 46-series large-format cell developed by EVE Lithium Energy. Its name directly reflects its dimensions: 46mm in diameter and 95mm in height. Following Tesla's 4680 battery, the 46950 battery is a flagship product in this technology line from a domestic battery manufacturer. It is also available as an EVE 3.7V 31.9Ah cell, making it ideal for both large-scale applications and customized 3.7V battery pack designs.
Core Advantages of the EVE 46950
1. Extremely High Energy Density
High volumetric efficiency: The large cylindrical structure (especially when combined with full-tab technology) allows for greater space utilization within the pack, reducing inactive materials (brackets, connectors).High capacity: A single 46950 battery cell can reach 30–40Ah or higher, meaning fewer cells are needed to build packs. This simplifies architecture, boosts energy density, and extends EV range.This directly translates to cylindrical lithium ion batteries powering electric vehicles with longer ranges, effectively addressing range anxiety.
2. Excellent Fast-Charging Performance
Full-tab (tab-less) technology: Instead of only two tabs, the entire current collector acts as a tab, shortening current paths and lowering resistance.Benefits:Supports 4C or higher fast charging, reaching 10%–80% charge in as little as 15 minutes.Reduced heat and resistance improves safety and cycle life.These innovations make the EVE 3.7V 31.9Ah cell a benchmark for rapid charging in both EVs and energy storage.
3. Top-Tier Safety and Reliability
Cylindrical structural advantage: Cylinders resist internal pressure and remain stable, suppressing material expansion during cycling.Directional pressure relief: Explosion-proof valves release pressure safely, preventing violent failure.High consistency: Once manufactured at scale, large cylindrical lithium ion batteries deliver excellent consistency for long-term stable operation.
4. Excellent Cost Control Potential
Standardization: The 46-series format is emerging as an industry standard, reducing equipment and material costs.High energy density = lower system costs: Fewer cells and connectors reduce pack complexity and cost.Strong chemistry compatibility: The 46950 battery can use both high-nickel ternary and lithium iron phosphate (LFP) chemistries, balancing safety, cost, and performance.This adaptability also benefits customized 3.7V battery solutions for diverse industries.
5. Powerful Power Output
Thanks to full-tab technology and low internal resistance, the 46950 battery supports ultra-fast charging and extremely high discharge power. This enhances EV acceleration and allows energy storage systems to deliver high instantaneous power when needed.
