Pknergy spotlights 21700 battery solutions at CES Las Vegas

Shenzhen Pknergy Energy used CES in Las Vegas to promote its 21700 lithium-ion battery line for consumer, industrial and mobility applications. The company highlighted speed-to-prototype, large-scale output, international certifications and a global B2B customer base as demand for high-density energy storage grows.

Why it matters: - Pknergy is pitching 21700 batteries as a higher-density alternative to older cylindrical formats for electrification, mobility and industrial devices. - The company is framing standardized battery supply as a key requirement for manufacturers facing shorter product cycles and stricter safety demands. - Pknergy says its battery line is built for applications ranging from e-bikes and robotics to smart-home devices and factory automation.

What happened: - Shenzhen Pknergy Energy Co., Ltd. showcased its 21700 battery solutions at CES in Las Vegas on July 24, 2026. - The company presented the 21700 format as a 21mm-by-70mm lithium-ion cell designed for industrial and consumer uses. - Pknergy used the event to promote ODM and OEM partnerships with engineers and product developers.

The details: - Pknergy says its technical team includes more than 400 experts across R&D, production, testing and shipping. - Pknergy says it works with more than 10,000 B2B clients globally. - The company says its customer service team has 30 people and offers 3-minute responses. - Pknergy says customized design schemes can be delivered within 24 hours. - The company says functional prototypes can be provided within one week. - Pknergy says full-scale mass production can start in 20 days. - The 21700 cells are designed to support over 500 charge-discharge cycles. - Pknergy says the defect rate is kept below 0.01%. - The product line includes 4500mAh and 5000mAh configurations. - The cells use either high-strength steel or lightweight aluminum casings. - Pknergy says leakage is kept below 0.01%. - The company says the 21700 format offers a 35% increase in energy density, a 50% improvement in cell capacity and about 15% lower cost per watt-hour than the 18650 format. - Pknergy says its factory has more than 20 fully automated production lines. - The company says daily output reaches 4 million batteries and annual capacity exceeds 1 billion units. - The battery line carries UL certification and CE and IEC markers. - Pknergy says it has more than 10 international certifications, including RoHS, REACH, UN38.3, CB and KC. - The company says it has more than 300 patent applications. - Pknergy says quality control includes more than 100 internal processes and 100% AI-driven inspection of key manufacturing stages. - The company says its batteries have leading market share in multiple niche segments. - Pknergy says 70% of exports go to Europe, America and Southeast Asia.

Between the lines: - CES gives battery suppliers a global stage to position themselves as infrastructure partners, not just component vendors. - Pknergy's pitch combines technical specs, manufacturing scale and certification claims to appeal to procurement teams that want speed and compliance. - The emphasis on ODM and OEM services suggests Pknergy is targeting customers that want customized battery packs rather than off-the-shelf cells.

What's next: - Pknergy says it will continue offering technical specifications and customized battery solutions through its website. - The company is likely to use its CES presence to expand overseas B2B relationships as demand for higher-density batteries grows. - More information is available at the company's announcement. - Pknergy also shared social channels on Facebook, YouTube and X for follow-up contact.
