As a national high-tech enterprise specializing in the research, development, production, and sales of lithium batteries,
SUNHE has recently been making continuous strides in product technology,
with several high-performance battery products already reaching industry-advanced levels.

 
In terms of polymer lithium batteries, the company's product line covers multiple series including 4.2V standard, 4.35V high-rate, 4.4/4.45V high-capacity, and 5C fast-charging batteries.
The volumetric energy density of the high-rate 4.35V battery system is improved by more than 10% compared to the standard 4.2V system;
The improvement in the 4.4V high-capacity system reaches over 18%.;
The 5C fast-charging battery can be charged to over 90% capacity within 12 minutes, while the high-rate battery's discharge rate is increased up to 60C with a capacity retention rate exceeding 95%.

 
In terms of product form innovation, SUNHE has achieved mass production of curved batteries (flexible from 0 to 180 degrees), ultra-thin batteries (thickness ≥ 0.4 mm), and ring-shaped batteries (minimum dimensions of 2.8 × 8.0 × 9.0 mm).
Additionally, polymer gel all-solid-state batteries offer higher safety performance and longer cycle life, while high-temperature and low-temperature batteries can operate normally in environments ranging from -20°C to 80°C.

 
Currently, the company's products are widely used in fields such as Bluetooth headsets, smart wearable devices, aviation models, assistive vehicles, and energy storage products. They have obtained multiple certifications including ISO9001, ISO14001, UL, and CE, with all performance indicators of the products ranking among the top in the industry.
