Coin lithium manganese dioxide batteries are widely used, from quart watches and clocks, to the long-term reliability of the backup power supply to TPMS (tire warning monitoring system), IoT equipment and car keyless entry system within 10 years. Therefore, the market for coin lithium manganese oxide batteries is rapidly expanding. In this diversified electronics sector, Murata is developing and producing coin lithium manganese dioxide batteries from a new perspective: it is meeting market demand while accumulating data on battery discharge characteristics, long-term reliability and safety characteristics. The lithium metal used for the anode of the coin lithium manganese dioxide battery has a maximum capacitance per unit weight (3. 86 Ah / g in all materials available for the anode). Therefore, a battery having a high energy density can be produced. Moreover, by using different active materials as the cathode, batteries having different characteristics can be manufactured. Murata has commercialized a coin lithium manganese dioxide battery that uses manganese dioxide as an active cathode material for excellent stability.

CR2477W 3V 1000mAh Primary Button Cell for Ocean Telemetering System discharge characteristics
CR2477W 3V 1000mAh Primary Button Cell characteristics: Lightweight, high voltage and high energy density. (The battery voltage is 3V, which is almost twice that of a normal alkaline or manganese battery. This means that the number of batteries required for the device can be halved to maximize space savings and weight.) Excellent discharge characteristics (Even if it is discharged for a long time, the voltage characteristics are kept stable, which greatly improves the reliability of the device using the battery. This equipment is also maintenance-free (very few batteries need to be replaced).) Excellent temperature characteristics (Murata's original organic electrolytes provide excellent properties in a wide range of temperatures from low to high.) -40 to +125 degrees Celsius (heat resistant), Excellent resistance (Leakage The newly developed battery structure and electrolyte ensure long-term maximum leakage resistance.) Excellent long-term reliability (Carefully selected active materials are used for the active materials and electrolytes. These materials are sealed using Murata's innovative technology to minimize battery self-discharge. The annual self-discharge rate at room temperature and normal humidity is less than 1% of the rated capacity.)
