Marketed under the global brand ZFCHUNT, we are a global supplier with over 10 years of combined R&D and industrial application experience in the new energy lithium battery sector, focusing on delivering reliable power solutions for consumer electronics. 3C digital lithium batteries are designed for consumer electronics manufacturers, portable power brands and OEM/ODM clients, addressing core industry pain points including insufficient battery life, short cycle lifespan, thermal safety risks and lack of flexible customization for specialized device requirements. Our products strictly follow UN38.3, IEC 62133 and UL 1642 international standards, with core technological breakthroughs in self-developed cell screening, intelligent BMS management systems and high-consistency assembly processes. Currently, our products are exported to dozens of countries and regions across Europe, North America, East Asia and Southeast Asia, with performance verified in wearable electronics, portable power, smart home devices and other 3C application scenarios. All products hold UL, CE, RoHS and UN38.3 certifications, recognized as reliable power solutions for global consumer electronics markets.
3C digital lithium battery is a rechargeable secondary battery that stores and releases energy via the intercalation and deintercalation of lithium ions between cathode and anode materials, developed based on high-purity electrode materials and intelligent battery management systems. It serves as a core power component for consumer electronics, supporting stable power supply for a wide range of 3C devices.
Main product series to meet diverse application demands include:
1. Consumer Wearable Series: Positioned for small-sized wearable devices, applicable for Bluetooth earphones, smart watches and fitness bands, with core features of lightweight design and low self-discharge rate.
2. Portable Power Series: Positioned for high-capacity portable power devices, applicable for power banks and outdoor portable power stations, with core features of high energy density and fast charge-discharge capability.
3. Smart Device Series: Positioned for high-reliability smart devices, applicable for surveillance cameras, beauty devices and portable medical equipment, with core features of high consistency and long cycle lifespan.
Our product design is centered on high safety, high energy density, easy integration and long lifespan, fully complying with full lifecycle reliability design standards to deliver stable, low-maintenance and cost-effective power solutions for clients.
The core working principle of 3C digital lithium batteries is based on the reversible movement of lithium ions between cathode and anode materials. The complete operation logic is divided into two core processes:
1. Charging process: When external power is applied, lithium ions deintercalate from the cathode material, pass through the electrolyte and separator, and intercalate into the anode graphite material to store energy.
2. Discharging process: When connected to an external load, lithium ions deintercalate from the anode and return to the cathode, releasing electrons to form a current that powers the connected device.
Core innovative modular architecture includes:
1. Intelligent BMS module: Self-developed battery management system that provides overcharge, overdischarge, short circuit and abnormal temperature protection, significantly improving battery safety performance.
2. High-consistency cell assembly: Automated spot welding and laser welding processes that reduce internal resistance fluctuation, improving the consistency of battery pack performance.
Compared to traditional 3C lithium battery solutions, our products address long-standing industry pain points: traditional solutions face high thermal runaway risk, short cycle lifespan and limited customization capability. Our design increases thermal runaway temperature by 40% via high-stability cathode materials, extends cycle lifespan to over 2000 cycles (twice the industry average for standard 3C batteries), and supports full-specification customization to match specialized device requirements.
All parameters are tested under standard 25℃ room temperature conditions, with strict tolerance control. We provide full parameter test reports for each batch, and support third-party authoritative testing.
