Xinghai Energy Headway 40146L Battery Cell Test Release

high-rate discharge stability breaks through again--3C/6C continuous discharge capacity retention rate exceeds 99%, temperature rise control leads the industry

Zhejiang, China, February 28, 2025-- Zhejiang Xinghai Energy Technology Co., Ltd.'s latest "Headway 40146L 3.2V20Ah lithium iron phosphate battery cell discharge test report" shows that this battery cell exhibits excellent stability and temperature control performance under extreme discharge conditions, marking a new level of high-rate power battery technology.

I. Core test highlights

1. 3C high rate cycle stability

• After 10 consecutive 3C (60A) discharges for 60 seconds, the single discharge capacity is stable at **1.0008~1.0010Ah** (fluctuation <0.02%), the discharge end voltage is maintained at **2.9455V or above**, and the temperature rise is only **+8.6°C** (initial 29.4°C→38.0°C).
• **Technical value**: Meet the needs of high-load scenarios such as rapid acceleration of electric vehicles and instantaneous frequency modulation of energy storage systems.

2. 6C ultra-high rate pulse discharge

• In 20 6C (120A) 10-second pulse discharges, the capacity output consistency reached **99.97%** (0.3332~0.3333Ah), and the temperature rise was controlled at **+5.0°C** (30.0°C→35.0°C).
• **Industry comparison**: Similar products generally experience ≥10% capacity attenuation under 6C conditions, and the temperature rise exceeds +15°C.

3. Full-rate continuous discharge performance

- Breakthrough performance: 3C continuous discharge still maintains 96% of the rated capacity, which is better than the industry average of 90%.

II. Technical analysis and scenario adaptation

• Material innovation: Nanoscale LFP positive electrode coating technology is used to reduce lithium ion diffusion impedance and improve high-rate discharge efficiency.
• Structural optimization: The three-dimensional ear design makes the current distribution uniform during 6C pulse discharge to avoid local hot spots.

Application verification:

• Adapt to the frequent start-stop conditions of electric commercial vehicles (3C cycle test simulation);
• Meet the instantaneous high power requirements of industrial robots (6C pulse test simulation);
• Support the long-term stable operation of the energy storage system (1C temperature rise is only +7.7°C).

III. Quality Commitment and Certification

• Certified by GB/T 31486-2015 "Electrical Performance Requirements and Test Methods for Power Batteries for Electric Vehicles";
• All products provide a 5-year/3000 cycle warranty (based on the 10-cycle zero-attenuation data of 3C in the test);
