The Howell Bobbin type Li-SOCl₂ battery, when connected in parallel with a capacitor, forms a “long-short combination” hybrid power solution. This design is specifically tailored for devices that require both long standby time and instant burst power. The high energy density lithium battery provides long term, steady power, while the high power density capacitor delivers a large current pulse when needed. With its “deploy once, use for long” characteristic, this solution becomes an ideal power source for many IoT devices, especially those deployed in outdoor or industrial environments where battery replacement is difficult.
Product Application

Medical devices, communication equipment, navigation systems, sensors, remote monitoring, automotive electronics, electronic equipment, instruments and meters, IOT, industrial measurement.
