NICHICON CORPORATION expanded its SLB series of small li-ion rechargeable batteries to include φ8 and φ12.5 size versions. The SLB series characteristics include rapid charge/ discharge and have long life.

The SLB series will be exhibited at CEATEC 2020 ONLINE from Tuesday, October 20, to Friday, October 23.

Overview and Development Background
Small li-ion rechargeable batteries are an essential part of new products and services using big data, artificial intelligence and cloud computing. This includes the expansion of environmental power generation systems that convert natural energy such as light, heat, vibration and radio waves into electricity, as well as the development of car electronics used in autonomous vehicles.

Main Features
This product utilizes lithium titanate for its cathodes giving them a high-rate* (max. 20C) charge/discharge performance with densities similar to an electric double-layer capacitor. It is also durable, capable of tens of thousands of charge cycles at a high rate, and boasts low temperature characteristics enabling operation down to -30°C. The SLB series is safe, it has an extremely low risk of igniting or smoking due to less lithium metal separation, which causes short circuits and deterioration.

Utilizing our winding manufacturing technologies that we have developed through our aluminum electrolytic capacitor production, we can supply ultra-small lead-type batteries with a diameter of 3 mm and a length of 7 mm for use in IoT edge terminals and smartphone styluses. In response to the market need for larger capacity products, we have added a version with a diameter of 8 mm and length of 11.5 mm, and one with a diameter of 12.5 mm, and a length of 40 mm. These additions make it possible to use the SLB series in a wider range of applications.

Going forward, we will be developing product lines for efficient energy use to contribute to the realization of a bright future for society and the prevention of global warming.

Terminology Explanation
*High-rate rapid charge/discharge: The current rate when charging/discharging battery capacity in one hour is defined as 1C. The ability to charge at a rate greater than 1C
indicates high-rate rapid charge/discharge performance.
