NICHICON CORPORATION will begin marketing evaluation boards to accelerate thedesign process for applications where the SLB series of small lithium-titanate
rechargeable batteries are to be used. The SLB series has become a top-selling
product in the small rechargeable battery market, having shipped over 50 million units
in total since its launch in 2019.
In order to promote carbon neutrality, disposable non-rechargeable batteries are being
replaced by rechargeable batteries paired with environmentally friendly power
generation from sustainable sources. The evaluation board allows for easy evaluationof power circuits incorporating the SLB series and various environmental power
generation devices. We will introduce this product at Sensors Converge 2023, a trade
show specializing in sensors and applied technologies, to be held in Santa Clara,California (US), from Tuesday, June 20 to Thursday, June 22.

Overview and Development BackgroundLong-life power supplies are essential for the development of IoT devices that require
maintenance-free operation. Replacing the conventional non-rechargeable batteries
with a power supply that combines an environmentally friendly power generation device
and a rechargeable battery requires significant design work. Using this evaluation
board makes it possible to easily examine the use of power supplies us ing
environmentally friendly power generation.

1Features
The evaluation board can be used to easily configure a power supply using
environmental power generation by inserting the SLB series directly into the board
and connecting it to a power generation device such as a solar power system. The
built-in power management IC (PMIC) allows power collection efficiency to beoptimized according to the power generation device used. The PMIC is equippedwith two power supply outputs, which can be used in different ways according to theapplication.
We are able to propose a very low-loss solution by using the low-power-consumption
AEM series from Belgium-based e-peas for the PMIC and the MAX1722x series from
Analog Devices, Inc., also known for its low power consumption, for the output
DC/DC converter.
