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

CASE02
Environmental sensor
-
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.

Energy harvest
-
It is possible to realize energy harvesting IoT equipment that utilizes a minuscule amount of environmental power generation (e.g., light, vibrations and flow rate). This is done by using an embedded controller that utilizes the RE family of Renesas and the small Li-Ion rechargeable batteries of Nichicon .
