SUNHE's ultra-thin high-capacity semi-solid lithium battery features a semi-solid composite electrolyte architecture that achieves an exceptional balance between slim profile and high energy density.This innovation provides a systematic solution to the longstanding challenges of capacity degradation, leakage, and swelling associated with thinner liquid lithium batteries,
making it ideal for embedded installation in ultra-slim devices while significantly enhancing both safety and battery life.
【Technological Innovation – Resolving the Thinness vs. Capacity Trade-off】
As smart wearables continue to evolve toward lighter and thinner designs, conventional liquid lithium batteries have struggled to maintain capacity and safety at reduced thicknesses.
SUNHE's new semi-solid battery replaces traditional liquid electrolytes with a semi-solid composite alternative, effectively minimizing leakage and swelling risks while delivering higher energy density within confined spaces.
This offers an ideal power solution for smartwatches, smart glasses, medical monitoring devices, and other terminal products that demand exceptional compactness and extended runtime.
【Proven Excellence – Leading Innovation in Small Lithium Batteries】
As a nationally recognized high-tech enterprise and one of the drafters of Guangdong Province's smart wearable lithium battery standards, SUNHE has been dedicated to the R&D, production,
and sales of small polymer lithium batteries since its establishment in 2012, with technical specifications consistently ranking among the industry's best.
The company operates a lithium-ion battery production line with an annual capacity of 15 million ampere-hours, and its products hold CE, UL, KC, CB, PSE, UN38.3, and other international certifications.
