ABOUT ”SLB”
"SLB” series are “Small Li-Ion Rechargeable Batteries” suitable for IoT and wearable applications
which utilize lithium titanate (LTO) for the negative electrodes, realizing
(1) Long life of more than 25,000 charge/discharge cycles
(2) High-density input/output approaching electric double layer capacitors (EDLCs)
(3) Capable of charging at low rate using energy harvesting
(4) Low temperature characteristics enabling operation even at -30 ℃
(5) Extremely low possibility of explosion or ignition even when used under harsh conditions
DEVELOPMENT
BACKGROUND
Small Li-Ion Rechargeable Batteries that achieve both high power density and high energy density
have been developed by using SCiB™ technology of Toshiba Corporation.
Characteristic

electric double layer capacitors (EDLCs)
Low charging current
Capable of charging at low rate using energy harvesting
Low temperatures
Possible to use in cold regions (-30deg.C)
Safety
Extremely low possibility of explosion or
ignition even when used under harsh conditions
Extremely low risk
of rupture or
ignition
and high safety.

CASE STUDY
-
CASE01
Stylus Pen
-
NICHICON CORPORATION's SLB Series of Small Li-Ion 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.

CASE02
Environmental sensor
-
The SLB series continues to be used as a secondary battery for the environmental sensor board "RIOT-002". By combining the environmental sensor board with a solar cell or other device, environmental data can be acquired anywhere, and data can be transmitted via BLE communication. By installing the SLB series on this board, it can operate continuously as a sensor, making it maintenance-free.
