Nichicon Expands SLB Series with High-Temperature Model (80°C)
11/13/2025
Nichicon Corporation has expanded its SLB Series of small lithium titanate (LTO) rechargeable batteries to include a new high-temperature model capable of operation from -30°C to 80°C. This durable addition maintains the series’ signature features of rapid charging/discharging, long life, high safety, and excellent low-temperature performance. The product will be exhibited as a reference model at EdgeTech+ 2025, held at Pacifico Yokohama from November 19–21.Background
Since its debut in 2019, the SLB Series has become one of Nichicon’s best-selling products, with over 90 million units shipped for use in communication and IoT devices. As IoT and big data applications expand, demand for reliable, long-life power sources has grown. Nichicon developed this new model to meet market needs for batteries that can operate in both extreme cold and high heat.
Features
By analyzing heat degradation mechanisms and optimizing the electrode foil and electrolyte, Nichicon improved thermal resistance and achieved outstanding cycle life. In testing at 80°C (20C rate, 100% DOD), the battery maintained 80% capacity after about 19,000 cycles (10 mAh sample). Four size variations are available, from 0.8 mAh to 130 mAh, providing flexibility for applications in IoT devices, industrial equipment, and outdoor infrastructure. These long-life batteries also reduce maintenance needs, supporting sustainability goals.Specifications
