Electronic Shelf Labels (ESL) See Explosive Growth; Power Glory’s CR-D Ultra-Low Temperature Series Opens Up a New Blue Ocean in Retail Digitalization
The global retail industry is undergoing a profound digital transformation, and one visible change is quietly taking place on supermarket shelves—traditional paper price tags are being replaced on a large scale by electronic shelf labels (ESLs). At the same time, a long-overlooked technical challenge is gradually coming to light: How can electronic shelf labels in refrigerated sections operate reliably in extremely cold environments?
The CR-D ultra-low-temperature battery series, independently developed by Power Glory, offers a critical battery solution for this scenario with its discharge capability at ultra-low temperatures of -55°C.
The ESL Market Is Gaining Momentum, and Battery Demand Is Surging in Tandem.
The adoption of electronic price tags is accelerating worldwide. According to the latest report from Global Market Insights, the electronic price tag market is projected to reach $7.4 billion by 2035, with shipments totaling 765.2 million units, representing a compound annual growth rate (CAGR) of 12.7% over the forecast period. The primary driver of this growth is the wave of retail automation, including demands for real-time pricing, dynamic promotions, and digitized inventory management.
Extreme Cold Environments in Refrigerated Cabinets: The “Last Mile” Challenge of Retail Digitization
However, the large-scale deployment of electronic price tags has not been without its challenges. The installation of price tags in supermarket refrigerated and frozen food sections is widely regarded by the industry as the “last mile” challenge of retail digitization.
Product management in low-temperature storage areas presents significant challenges: First, the extremely low temperatures cause conventional electronic devices to experience slow screen response, a sharp drop in battery life, or even complete failure when operating in such environments for extended periods. Second, high humidity and severe condensation pose a severe test for any electronic device.
Although electronic price tags designed for low-temperature environments have achieved certain hardware breakthroughs—such as some models supporting stable operation at -25°C and featuring IP67-rated water and dust resistance—all of this depends on a stable and reliable power supply. Whether the batteries in electronic price tags have sufficient discharge capacity at low temperatures directly determines whether the devices will function or fail in extremely cold environments.
Power Glory CR-D Series: -55°C Ultra-Low Temperature Performance, Breaking the Ice for Retail Digitalization.
This is precisely the core value of Power Glory’s CR-D ultra-low temperature battery series. As a “hidden champion” in China’s lithium-manganese button cell sector, Power Glory enjoys a strong first-mover advantage in the electronic price tag market. The company has developed lithium-manganese battery products specifically for the electronic price tag market and has established stable partnerships with numerous global electronic price tag clients.
Power Glory is at the forefront of the industry in terms of breakthroughs in low-temperature battery technology. Conventional button batteries are prone to insufficient power or malfunction in low-temperature environments because cold temperatures increase the viscosity of the electrolyte and slow down the chemical reaction rate at the electrodes, leading to higher internal resistance. In contrast, Power Glory’s CR-D series button batteries utilize advanced new lithium battery performance technologies, enabling them to maintain excellent discharge capacity and deliver outstanding performance even in ultra-low-temperature environments as low as -55°C. 
The CR-D series is a key member of Power Glory’s wide-temperature battery lineup, joining the CR-HT and CR-T series to form a comprehensive product line covering temperatures ranging from extreme cold to high heat.
Among these, the CR-HT series is capable of operating within an ultra-wide temperature range of -40°C to 125°C, offering superior discharge stability and a long service life. This technical capability to adapt to such a wide temperature range has broken down industry barriers to the use of traditional batteries in extreme environments, enabling electronic price tags to be deployed in virtually any scenario.
The CR-D series’ ultra-low-temperature performance provides a solid guarantee for the stable operation of electronic price tags in extremely cold regions. Whether in fresh produce cold chains, refrigerated meat sections, or frozen ice cream sections, electronic price tags equipped with CR-D batteries ensure clear screen displays, rapid refresh rates, and uncompromised battery life.
