FDK Corporation, led by President Yoshiyoshi Nagano, has officially launched the SCD4532K model of their SMD small oxide all-solid-state battery, SoLiCell, designed for high energy density. Aiming to enhance the capabilities of their battery technologies, FDK has introduced this new model that supports constant voltage charging. Sample shipments are slated to begin in December 2025.
The SoLiCell SCD4532K embodies several innovative features, including compact design, high voltage, and impressive energy density. Most notably, this battery is engineered to accommodate broader charging temperature and voltage ranges. This adaptability allows for constant voltage charging via simpler circuitry while maintaining the high thermal stability characteristic of its predecessors.
One of the significant advantages of the SCD4532K is its ability to simplify the charging circuit, as it doesn't require precise voltage control. This results in fewer components, reducing overall costs and enabling further miniaturization of devices that utilize these batteries. Additionally, it preserves the 3V output and durability that customers expect from previous models, while integrating new functionalities that make it suitable for a diverse range of applications.
Applications for the SCD4532K include miniature IoT devices, wearable technology, Real-Time Clock (RTC) backup power, and backup power for SRAM/MCU systems. Moreover, it can be combined with energy harvesting equipment, making it highly versatile—especially in harsh environmental conditions like high temperatures and vacuum.
To highlight the advancements associated with the SCD4532K, FDK will showcase this product at the 5th Smart Logistics Expo, occurring from January 21 to 23, 2026, at Tokyo Big Sight. Visitors to the FDK booth will witness firsthand the innovative capabilities of this new all-solid-state battery.
Additionally, FDK is continuing the parallel shipment of the SCC4532K, a high energy density model launched before the SCD4532K release. As FDK Corporation embarks on this new journey of battery innovation, they remain committed to improving power capacity and output, expanding the range of applications for their batteries in various sectors.
With the ongoing advancements in battery technology, FDK is positioning itself as a trailblazer in the energy sector, contributing to the development of advanced energy solutions for contemporary challenges. Such efforts reflect FDK's ongoing dedication to delivering cutting-edge products, ensuring power reliability, and supporting the growth of technology that aligns with sustainable practices.
