A Case Study in Custom Cell Development & Assembly Craftsmanship

In this project, we delivered two core battery solutions—NiMH rechargeable batteries and Li-SOCl₂ primary lithium batteries—tailored for clients requiring long-lasting, stable, and high-performance power sources across industrial environments.

But beyond product delivery, this case reflects our deep engineering strength and flexible manufacturing capabilities in cell customization, battery assembly, and design integration.

01 | Custom NiMH Battery Packs — Designed for Real-World Durability

Our NiMH production line supports a wide range of cylindrical cell sizes, from 2/3AA to D type, with the ability to customize voltage, capacity, and assembly structure.

In this case, we:

• Selected high-drain NiMH cells with enhanced cycle stability (800+ cycles)

• Designed tab-connected and shrink-packed battery packs with precise polarity control

• Integrated spot-welded nickel strips, PVC wrapping, and custom wire leads for seamless plug-and-play installation

• Applied triple-layer quality control, including capacity sorting, internal resistance testing, and simulated load tests

Our packs are widely compatible with handheld devices, medical tools, and consumer electronics—where reliability and safety matter most.

02 | Advanced Li-SOCl₂ Batteries — Built for Long-Term Field Deployment

Lithium Thionyl Chloride (Li-SOCl₂) batteries demand precision—from material purity to sealing technique. For this batch, we produced ER14250 and ER18505 models, focusing on extreme consistency in output and long-term shelf stability.

What sets our process apart:

• All cells are vacuum-sealed using laser welding to ensure absolute airtightness

• We utilize high-purity thionyl chloride, combined with spiral-wound cathode construction, enabling energy density up to 700Wh/kg

• Each battery undergoes ultra-low leakage current testing (<3μA) and thermal aging simulation before packing

• Optional PCB or fuse-protection can be integrated upon request

This level of precision makes our Li-SOCl₂ batteries ideal for remote sensors, industrial meters, asset trackers, and other mission-critical low-power applications.

Our Strength: Not Just a Supplier, But a Solution Partner

Whether it's battery pack structure, output characteristics, environmental adaptation, or custom housing, we work side-by-side with our clients to meet both electrical and mechanical demands. Our team supports:

• Small batch prototyping within 7–10 working days

• OEM/ODM service from cell to casing

• Design-for-assembly optimization

• Full traceability for industrial-grade quality assurance

Every battery pack we deliver carries not just energy—but also the precision and dedication behind it.
