본 발명은 전지와 캐퍼시터가 연결된 하이브리드 전지에 관한 것이다.The present invention relates to a hybrid battery in which a battery and a capacitor are connected.

최근 들어 무선 통신의 급속한 성장에 따라 휴대용 기기 및 장비가 기존 아날로그 방식에서 디지털 방식으로 바뀌면서 첨단화 되고 있다. 이러한 무선 통신기기는 무선으로 데이터를 송신하기 위해서 주기적인 순간적인 고전류 펄스가 생성되어야 한다.Recently, with the rapid growth of wireless communication, portable devices and equipments are being advanced by changing from analogue to digital. Such wireless communication devices must generate periodic instantaneous high current pulses to transmit data wirelessly.

이러한 무선통신기기의 순간적인 고전류 펄스를 생성하기 위한 전원으로 단 독 전지만을 사용하게 되면 대전류 방전시 자체저항의한 전압강하가 크게 발생되기 때문에 출력전압이 낮아지게 되고, 대전류 방전에 의한 수명이 짧아지게 된다. 이러한 문제를 해결하기 위하여 전지를 주 전원으로 하고 캐퍼시터를 보조 전원으로 한 하이브리드 전지를 사용함으로써 순간적인 고전류 출력특성을 충족시키면서 전지의 수명을 연장시키도록 하고 있다.When only a single battery is used as a power source for generating instantaneous high current pulses of such a wireless communication device, a large voltage drop due to its own resistance occurs during a large current discharge, resulting in a low output voltage and a short lifetime due to a large current discharge. You lose.
