Quelle peut être la taille d’une pile bouton ? Power Glory propose des tailles allant de 9,5 mm à 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.
Le portefeuille de produits de Power Glory (code boursier : 920237) commence par cette minuscule pile CR920 et s’étend jusqu’à la CR3832 — une batterie de 38 mm de diamètre et d’une capacité de 850 mAh. Cette gamme étendue, allant de la plus petite à la plus grande, témoigne de la profonde expertise technique que l’entreprise a développée au fil de plus de vingt années d’engagement exclusif dans le domaine des microsources d’énergie au lithium.
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%.
Une petite taille ne laisse aucune place à la redondance. À mesure que le volume se réduit, l’impact de toute tolérance dimensionnelle, de tout problème de précision d’assemblage ou de toute impureté — qu’il s’agisse du matériau de la cathode, de l’électrolyte, de la bague d’étanchéité ou du boîtier — se trouve amplifié de manière exponentielle. La capacité à assurer une production stable et en masse d’une batterie mesurant Φ9,5×2,0 mm est, au fond, le reflet des doubles compétences de l’entreprise en recherche et développement ainsi qu’en fabrication.
II. Un large spectre : le fruit d’une gamme de produits très étendue
Un coup d’œil au tableau des spécifications de la série CR de Power Glory révèle une vaste palette de modèles : de la CR920, CR927, CR1025, CR1216, CR1220, CR1225, CR1616, CR1620 et CR1632, en passant par la CR2016, CR2025, CR2032 et CR2050, puis la CR2320, CR2325, CR2330, CR2335, CR2354, CR2430, CR2450, CR2477 et CR3032, jusqu’au modèle le plus grand, la CR3832 — à elle seule, cette série CR comprend 23 modèles distincts conçus pour fonctionner à température ambiante.
À quel point ce spectre de produits est-il large ? Les diamètres varient de 9,5 mm à 38,0 mm — soit un écart quadruplé ;
Les épaisseurs oscillent entre 1,6 mm (CR1216/CR1616/CR2016) et 7,7 mm (CR2477) ;
Les capacités s’étendent de 20 mAh (CR920) à 1000 mAh (CR2477), soit un écart de cinquante fois.
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. Conditions de fonctionnement exigeantes, puissance de sortie constante
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:
Résistance aux températures extrêmes : La série CR/HT, conçue pour les très hautes températures, peut fonctionner dans des environnements allant de -40 °C à 125 °C. Ces batteries sont spécialement adaptées aux applications telles que les systèmes de surveillance de la pression des pneus (TPMS) — des dispositifs montés directement sur les moyeux de roues, où ils doivent supporter à la fois une chaleur intense et des forces centrifuges. Parallèlement, les séries CR-T et BR (lithium-carbone monofluorure) couvrent une plage de température comprise entre -40 °C et 85 °C. Ce large spectre thermique permet à ces piles bouton d’aller au-delà des environnements intérieurs climatisés pour s’intégrer dans des applications automobiles, industrielles et en milieu extérieur.
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).
