PKCell to showcase ER26500 LiSOCl2 battery solutions at Hong Kong Electronics Fair 2026

PKCell plans to present ER26500 lithium thionyl chloride battery solutions at the HKTDC Hong Kong Electronics Fair 2026 in August 2026, targeting smart city, industrial IoT and utility applications. The company is positioning the cells and modular battery-capacitor systems as options for long-life, low-maintenance deployments that still handle high pulse loads.

Why it matters: - Smart city, industrial IoT and utility networks need batteries that can sit idle for long periods and still deliver sudden bursts of power. - PKCell is using the Hong Kong Electronics Fair 2026 to pitch ER26500 LiSOCl2-based solutions to engineers and procurement teams working on those deployments. - The event gives suppliers a venue to compete on battery life, safety compliance and customization, not just unit price.

What happened: - PKCell said it will showcase high-quality ER26500 LiSOCl2 battery solutions at the HKTDC Hong Kong Electronics Fair 2026 in Hong Kong. - The company also plans to highlight modular systems that pair primary lithium cells with Hybrid Pulse Capacitors for pulse-heavy applications. - PKCell identified smart city infrastructure, industrial telemetry, parking radars and utility metering as target use cases.

The details: - The ER26500 C-size lithium thionyl chloride cell has a 3.6V nominal voltage and a 9000mAh nominal capacity. - The cell is designed for low self-discharge, with annual loss claimed at less than 1% during storage. - PKCell says the design uses glass-to-metal seals and laser-welded stainless steel containers to help prevent leakage and protect internal chemistry. - The company says automated cell processing is used to keep batch performance consistent at scale. - PKCell says its ER+HPC modular system combines the ER26500 battery with a Hybrid Pulse Capacitor. - The combined setup is designed to handle low-power standby periods and high-amplitude transmission bursts. - The integrated module is listed as operating from minus 55 degrees Celsius to plus 85 degrees Celsius. - The company says buyers can request multi-cell configurations, including 1S4P pack topologies, for edge-computing hardware. - PKCell says it offers custom battery pack design support, including dimension matching for proprietary circuit board and enclosure requirements. - The company says its quality checks include open-circuit voltage and internal resistance screening before final loading.

Between the lines: - PKCell is framing battery sourcing as a systems-engineering decision, not a commodity purchase. - The emphasis on compliance, packaging and thermal performance suggests the company wants to win projects where downtime and logistics risk are expensive. - The mix of primary cells and capacitors reflects a broader market need: long shelf life plus pulse performance in the same power source.

What's next: - PKCell will use the fair to meet international engineering teams and procurement buyers. - The company is also directing visitors to more information. - PKCell listed a Facebook page for social updates at its social channel. - The company expects regulatory documentation, transport readiness and traceability to remain central to export sales of Class 9 lithium batteries.

The bottom line: - PKCell is betting that long-life primary lithium batteries paired with pulse-capacitor modules will stand out at a trade show where industrial buyers want reliability, compliance and customization in one package.
