Overview

The button-type titanium carbon lithium rechargeable battery is a small rechargeable battery developed as a backup power source for real-time clocks and SRAM like digital cameras and mobile phones. It provides fully 10 times the capacity of a capacitor of the same size.

Construction

Principle and Reactions

The button-type titanium carbon lithium ion rechargeable battery uses lithium titanium oxide as the positive material, carbon as the negative material, and organic electrolyte.

Features

•Approx. 1.5V operating voltage
The operating voltage is about 1 to 1.5V the same as the SR, LR battery.
•Wide range charging voltage (Fig. 1)
Charging voltage is 1.6 to 3.15V.
•Excellent cycle performance (Fig. 2)
500 charge/discharge cycles is archived because by utilizing lithium ion.
•Wide temperature characteristics (Fig. 3)
Usable in a wide temperature range of -20 to 60 deg. C.
•Excellent overcharge characteristics
A special formulated organic electrolyte is employed to provide stable discharge characteristics even if charged for 10 years at 3.15V at 20 deg. C.(under accelerated test conditions conducted by Maxell)
•Superior leakage resistance
Leakage resistance can withstand over 1,200 heat shock cycles between 60 deg. C. and -10 deg. C.
