Hoe groot kan een knoopcelbatterij zijn? Power Glory biedt maten variërend van 9,5 mm tot 38 mm.
How small is a coin cell battery? The smallest coin cell CR920PH produced by Power Glory measures just 9.5 mm in diameter, 2.0 mm in thickness, and weighs a mere 0.5 grams—so inconspicuous that it would go virtually unnoticed when mounted on a motherboard.
Yet, it is precisely this “infinitesimally small” battery that serves as the ultimate test of a company’s “grand capabilities.” As a battery shrinks in size, the requirements for materials, packaging, consistency, and reliability become nearly demanding to the point of severity; with space compressed to the millimeter scale, every increment of performance must be “wrested” from the manufacturing process itself.
Het productportfolio van Power Glory (aandelennummer: 920237) begint met deze piepkleine CR920-cel en reikt helemaal tot de CR3832—een batterij met een diameter van 38 mm en een capaciteit van 850 mAh. Deze brede productreeks, die zich uitstrekt van de kleinste tot de grootste, belichaamt de diepgaande technische expertise die het bedrijf heeft ontwikkeld gedurende meer dan twee decennia van toegewijde focus op het gebied van lithium-micro-energiebronnen.
I. Compact Size: A Testament to Both R&D and Manufacturing Prowess
The CR920 measures 9.5 mm in diameter and 2.0 mm in thickness, with a nominal capacity of 20 mAh and a total weight of just 0.55 grams. Within such a confined volume, Power Glory has achieved a nominal voltage of 3V and a maximum pulse current of 5mA, while utilizing unique encapsulation technology to keep the annual self-discharge rate below 2%.
Kleine afmetingen laten geen ruimte voor redundantie. Naarmate het volume krimpt, wordt de impact van eventuele dimensionale toleranties, assemblageprecisieproblemen of onzuiverheden—van het kathodemateriaal en de elektrolyt tot de afdichtingsring en behuizing—exponentieel vergroot. Het vermogen om stabiele massaproductie te realiseren van een batterij met afmetingen Φ9,5×2,0 mm is in feite een bewijs van het dubbele vermogen van een bedrijf op het gebied van onderzoek en ontwikkeling én productie.
II. Een breed spectrum: het resultaat van een uitgebreide productlijn
Een blik op het specificatieblad van de CR-serie van Power Glory onthult een enorme variëteit aan modellen: van de CR920, CR927, CR1025, CR1216, CR1220, CR1225, CR1616, CR1620 en CR1632, via de CR2016, CR2025, CR2032 en CR2050, verder met de CR2320, CR2325, CR2330, CR2335, CR2354, CR2430, CR2450, CR2477 en CR3032, tot aan het grootste model, de CR3832—alleen al deze CR-serie omvat 23 verschillende modellen die zijn ontworpen voor werking bij normale temperaturen.
Hoe breed is dit productspectrum eigenlijk? De diameters variëren van 9,5 mm tot 38,0 mm—een vierdubbele spreiding;
De diktes variëren van 1,6 mm (CR1216/CR1616/CR2016) tot 7,7 mm (CR2477);
De capaciteiten variëren van 20 mAh (CR920) tot 1000 mAh (CR2477)—een verschil van vijftig keer.
Yet, coin-type batteries represent only a portion of Power Glory’s “eight core lithium battery product” portfolio. This lineup includes lithium-manganese coin cells (standard CR series, as well as wide-temperature CR-HT, CR-D, and CR-T series), lithium-carbon monofluoride (BR) coin cells, rechargeable lithium-aluminum alloy (ML) coin cells, and lithium-ion supercapacitors (LSC series). Complemented by cylindrical lithium-manganese batteries, soft-pack lithium-manganese batteries, and custom battery assembly services, these offerings form a comprehensive product matrix—spanning from micro-sized to cylindrical, primary (non-rechargeable) to rechargeable, and individual cells to complete power solutions. Power Glory ensures that no matter how much space is allocated within a device, customers can always find the perfect fit; the sheer breadth of this product family inherently simplifies the selection process.
III. Veeleisende bedrijfsomstandigheden, consistente vermogensoutput
Scaling up in size is not merely an increase in dimensions; it represents an expansion of performance boundaries. The smaller the device and the more extreme the operating environment, the more effectively a battery’s “true mettle” is put to the test:
Weerstand tegen extreme temperaturen: De ultra-hoge-temperatuur CR/HT-serie kan functioneren in omgevingen van -40°C tot 125°C. Deze zijn speciaal ontworpen voor toepassingen zoals bandenspanningscontrolesystemen (TPMS) – apparaten die direct op de wielnaven worden gemonteerd en waar ze zowel intense hitte als centrifugale krachten moeten weerstaan. Ondertussen bestrijken de CR-T- en BR-serie (lithium-koolstof-monofluoride) een temperatuurbereik van -40°C tot 85°C. Dit brede thermische spectrum stelt deze knoopcelbatterijen in staat om verder te gaan dan klimaatgecontroleerde binnenruimtes en zich te richten op automotive-, industriële- en buitenveldtoepassingen.
Handling Pulse Currents: The high-capacity, high-power CR-P/H&X series offers 10%–20% more capacity than standard models of the same size. With a maximum continuous current of up to 20mA and pulse currents reaching 75mA, they are perfectly suited for the power requirements of devices like car key fobs, RFID tags, GPS units, and Electronic Shelf Labels (ESL)—which typically remain in a low-power, micro-ampere standby state, only to require a sudden burst of power for data transmission.
Ensuring Long-term Reliability: The HT series features an annual self-discharge rate of less than 1%. The ability to both “perform when needed” and “retain power during storage” represents the most fundamental—yet most challenging—promise for any micro-power source.
From motherboard real-time clocks to automotive key fobs; from electronic scales, POS terminals, and digital watches to medical instruments; and from smart home systems to data transmission for photovoltaic installations and natural gas pipelines—the application portfolio of Power Glory coin-cell batteries serves as an “invisible power map” for the era of the Internet of Things (IoT).
IV. Kleine componenten, grote verantwoordelijkheden
As tiny, easily overlooked components within a device, button batteries carry a critical mission: they must remain functional even when the main power supply is cut off. Power Glory meets this rigorous demand for reliability through a comprehensive system encompassing R&D, manufacturing, standardization, quality control, and risk management.
Productieschaal: Een solide basis voor levering
Founded in 2004, Power Glory operates an R&D and manufacturing base spanning over 100 mu (approx. 6.7 hectares), supported by a professional team of approximately 650 employees and a monthly production capacity exceeding 66 million units. With about 60% of its products exported to markets including the United States, Germany, Sweden, Japan, South Korea, and India, the company has long provided ODM services to internationally renowned brands, demonstrating a robust capability for large-scale, global delivery.
Standaardisering als leidraad: Het bepalen van de industrienorm
Power Glory has participated in the drafting of five national standards, including “Primary Batteries – Part 1: General” (GB/T 8897.1-2021). As a vice-chair member of the China Lithium Battery Association, the company leverages its technical expertise to help shape industry standards.
Een uitgebreid systeem dat een solide basis legt voor kwaliteit van autoniveau
Power Glory holds certifications for ISO 9001, ISO 14001, ISO 45001, and the IATF 16949 automotive quality management system. It has been recognized as a National High-Tech Enterprise, a “Little Giant” firm (specializing in niche markets with cutting-edge technologies), and a “Green Factory” by the Ministry of Industry and Information Technology. To date, the company holds 91 patents—comprising 16 invention patents, 74 utility model patents, and 1 international patent—driving product upgrades through continuous innovation.
Uitgebreide risicobeperking en end-to-end veiligheidsgarantie
Power Glory’s products are covered by a $5 million global product liability insurance policy from CHUBB, providing risk protection across the entire lifecycle—from R&D to end-use—to ensure the safety of customers worldwide.
The history of Power Glory’s products is a chronicle of innovation, defined by the successful mastery of increasingly demanding requirements: smaller sizes, broader operating ranges, and resilience in more extreme environments. For over two decades, the company has remained steadfastly focused on miniature lithium power sources. In an era of the “Internet of Everything,” where devices are becoming smaller, thinner, and deployed in increasingly challenging environments, the company that can provide a comprehensive range of millimeter-scale power sources—capable of operating under diverse conditions with reliable delivery—effectively holds the “heart” of the smart device era.
