NICHICON CORPORATION’s SLB Series of Small Lithium Titanate Rechargeable Batteries have been adopted for use on the stylus pens (“S Pens”) of the Galaxy Note10 and Note10+(released in 2019,) as well as the Galaxy Note20 and Note20 Ultra (released in 2020) by Samsung Electronics Co., Ltd.
In recent years, in an IoT society where everything is connected to the network, everything will require a power supply, and in some cases, power supply wiring and battery replacement may be difficult.
Given these circumstances, energy harvesting technologies that convert energy from light, heat, vibration and radio waves into electricity are being developed. Small, long-life rechargeable batteries able to store and repeatedly discharge energy in high frequency cycles are desirable.

Independent power supply for IoT
Energy harvesting is possible in IoT equipment that utilizes minimal environmental power generation (e.g., light, vibration, and/or flow rate). This can be done using an embedded controller that utilizes the RE family from Renesas and the small Lithium-titanate rechargeable batteries from Nichicon.
FREQUENTLY ASKED QUESTIONs
The lithium titanate battery (LTO) shares many characteristics with the lithium-ion battery. One difference is the LTO anode. An LTO battery uses lithium titanate oxide, while a lithium-ion battery uses carbon. By using lithium titanate, the battery has a significant performance improvement.
The SLB is a battery with long leads, just like a standard capacitor. The leaded profile allows for soldering directly to the circuit board using hand soldering or a select solder technique. Lithium Titanate batteries require an additional mounting bracket or holder placed on a circuit board. The Nichicon SLB (LTO) take less board space allowing them to be used in very compact or densely populated circuit boards.
LTO batteries are safer; they have an extremely small risk of ignition if there is a short. The SLB, Nichicon’s LTO battery, has superior charge and discharge capabilities, such as a 20C charge rate. Even higher rates are possible with pulsed discharges, like those used in telecommunications.
‘The SLB can withstand up to 25,000 charge/discharge cycles and have a lower cold temperature rating than a lithium-ion battery. And its low internal resistance allows energy harvesters to charge with weak currents without loss. They will not ignite if a short occurs. In addition to the advantages previously mentioned, the SLB comes in aluminum electrolytic case styles and size.
