R & D Center
Cycle life laboratory
Three performance cabinets are used for testing the charge and discharge performance of finished batteries, including tests such as 100, 300, and 500 cycles, cycle life, capacity, and platform tests.
Environmental performance laboratory
Two high-low temperature chambers and three ovens are used for testing the environmental adaptability performance of finished batteries, including tests such as high-temperature discharge, low-temperature discharge, high-temperature and high-humidity cycling, and fully charged high-temperature storage.
Electrochemical analysis laboratory
One electrochemical workstation is used for testing battery electrode chemical reactions, including tests such as potential analysis and alternating current impedance testing.
Physical property analysis laboratory
Equipment such as laser particle size analyzers, tapped density meters, specific surface area analyzers, moisture analyzers, conductivity meters, and pH meters are used for testing the physical properties of battery raw materials, including tests such as particle size, specific surface area, tapped density, and moisture.
Structural analysis laboratory
X-ray inspection equipment is used for observing and measuring the internal structure and defects of battery raw materials, semi-finished products, and finished batteries.
Morphology analysis laboratory
Equipment such as scanning electron microscopes with energy-dispersive spectrometers and image analyzers are used for observing and measuring the surface microstructure of battery raw materials, semi-finished products, finished batteries, and important tools.
Finished product analysis laboratory
Equipment such as inductively coupled plasma spectrometers and gas chromatography-mass spectrometers are used for analyzing the inorganic and organic components of battery raw materials.
Thermal analysis laboratory
Equipment such as simultaneous thermal analyzers and adiabatic calorimeters are used for differential thermal and thermogravimetric analysis of battery raw materials or synthetic materials, as well as for testing battery thermal stability, safety, energy efficiency, and cycle life.
Safety performance laboratory
Testing devices such as needle penetration, overcharge, short circuit, thermal shock, vibration, and heavy weight impact are used for testing the safety performance of finished batteries.
- The battery is tested with a simple tuned vibration of 0.8mm amplitude.
- The vibration frequency changes at a rate of 1Hz/min within the range of 10-55Hz, and recovers within 90-100min.
- The battery vibrates along three mutually perpendicular directions. For cells with only two axes, the cell shall be tested perpendicular to each axis.
- At the end of the test, the sample will not catch fire, explode or leak.
