Nichicon Corp. has developed the new Small Lithium-Ion Rechargeable Battery (SLB series) in conjunction with Toshiba Infrastructure Systems & Solutions Corp. SCiB technologies.
The main feature of the SLB series includes:
1) A high rate of charge/discharge. The batteries are able to charge to approximately 80% in three minutes and discharge to 95% of the charge in three minutes.
2) The SLB is safe to charge even in a low temperature environment of -30°C as lithium does not deposit onto the negative electrode.
3) In the event of a forced internal short circuit, the possibility of an explosion is low, making the SLB safe.
4) High capacity retention rate of 80% or more even after 25,000 charge/discharge cycles at a rate of 10C.
The SLB are able to power environmental sensors for monitoring temperature, humidity, illuminance and other data for long periods of time when combined with a power supply IC. By utilizing the high rate characteristic of 20C (max), these batteries can be charged in a short time when used in combination with a step-up/step-down charging IC.
Operating voltage: 2.4 V
Max. Charging voltage: 2.8 V
Discharge cutoff voltage: 1.8 V
Rated Capacity: 0.35 to 150 mAh
Temperature Range: -30 to +60°C
Life: 25,000-hour life cycle
*Terminology Explanation – The current rate when charging/discharging battery capacity in one hour is defined as 1C. The ability to charge/discharge at a rate higher than 1C is referred to as high-rate high-speed charge/discharge performance.
