Nichicon SLB
Small Lithium Titanate Rechargeable Batteries (LTO)
Perfect for IoT & Wearable Devices.
The Nichicon SLB Series is a revolutionary family of lithium-titanate (Li-ion) rechargeable batteries. These batteries deliver exceptional performance, making them ideal for modern electronics such as IoT devices, wearables, and industrial applications.
Unlike traditional lithium-ion batteries, the SLB series provides fast charging, longer life cycles, and exceptional safety in a compact form. With the ability to function in extreme temperatures and support energy harvesting technologies, the SLB series represents the future of small-scale energy storage.
SLB Technical Advantages
Compact Size
SLB batteries are much smaller than traditional supercapacitors, taking up just 15% of the volume while delivering the same amount of energy. This makes them perfect for space-constrained designs in wearables, medical devices, and portable electronics.
High Charge-Discharge Cycle
SLB batteries retain 80% of their capacity after 25,000 charge-discharge cycles, significantly outlasting traditional Li-ion batteries, which degrade after about 1,000 cycles. This makes them ideal for long-term, maintenance-free applications such as IoT sensors and industrial monitoring systems.
Wide Range of Charging Capabilities
SLB batteries can be charged at both high and low currents, offering flexibility in charging strategies. Whether you need a quick 3-minute charge or a slow trickle charge for energy harvesting, SLB batteries can handle it. Unlike typical Li-ion batteries, they don’t require a dedicated charging IC for precise charging.
Safety
SLB batteries are designed with safety in mind. Unlike Li-ion batteries, they won’t easily ignite or suffer from thermal runaway even in the event of a short circuit. They can withstand piercing or crushing without risk of fire, making them ideal for devices that need to operate in harsh or unpredictable environments.
Wide Operating Temperature Range
SLB batteries perform reliably even in extreme temperatures. They maintain 50% of their energy storage capacity at temperatures as low as -30°C, where traditional Li-ion batteries would fail. This makes them a strong choice for outdoor or industrial applications.
Easy to Mount
SLB batteries can be soldered directly onto circuit boards, much like aluminum electrolytic capacitors, without any need for additional mounting fixtures. This reduces both complexity and the space required on your PCB.
Maintenance-Free Operation
As a rechargeable solution, SLB batteries eliminate the need for regular battery replacements, even in long-term applications. This is a crucial benefit for designs where maintenance is difficult or costly, such as in IoT deployments in remote areas.
Flexible Charging for Energy Harvesting
SLB batteries are optimized for energy harvesting systems, capable of charging from a variety of low-power sources such as solar panels (photovoltaic, or PV) and thermoelectric generators (TEG). Their flexibility makes them ideal for applications requiring wireless power transmission, energy harvesting, or sustainable energy sources.

Use Case
Samsung Galaxy Series S Pen
Customer: Samsung Electronics Co., Ltd.
Application: Galaxy Note Series S Pen
Challenge: The Galaxy Note9 was equipped with an electric double-layer capacitor (EDLC) for power, which was sufficient for basic functions. However, with the introduction of new features like Bluetooth connectivity and enhanced sensor capabilities in the Galaxy Note10 and beyond, power consumption increased significantly. Samsung needed a more efficient and compact energy solution that could handle the added power demand without increasing the size of the S Pen.
Solution: Nichicon’s SLB03070LR35 battery was selected to replace the EDLC, offering higher energy density and better performance in the same small footprint. The SLB battery provided a more efficient power source, enabling longer use between charges and supporting the increased functionality of the S Pen, such as Bluetooth 5.0 connectivity and the 6-axis sensor.
Key Benefits:
- Compact size: The SLB03070LR35Â fits perfectly within the small dimensions of the S Pen (5.8 x 4.35 x 105.08 mm).
- Enhanced power performance: Supports the new Bluetooth-enabled features and sensor integrations without compromising on size or weight.
- Reliable long life: The SLB battery’s high cycle life ensures the S Pen remains operational for an extended period without needing frequent recharges.
