축전지(storage battery)란 외부 전기에너지를 화학에너지 형태로 바꾸어 저장해 재사용할 수 있게 만든 전지로 충전지(rechargeable battery) 혹은 배터리(battery)라고 부른다. [그림 1]은 간단히 도식화한 축전지의 회로 모형을 나타낸 것이다.

축전기(storage battery)는 외부의 전기에너지를 화학에너지의 형태로 바꾸어 저장하는 장치이다. 축전기는 충전지(rechargeable battery) 혹은 배터리(battery)라고 불린다. [그림 1]에서와 같이 도선에 저항 이 존재하여 에너지가 충전되거나 방전될
concert, we see Co2 in form of gas.
Anyway, Today I explain to you about this, Electrochemical reaction. We convert Co2 to other materials using electrochemical reaction.
Electrolytic Cell
Electrochemical cell in which a non-spontaneous reaction is driven by an external source of current

rechargeable battery. Like an iPod but unlike most other cell phones, the battery is not user-replaceable. The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. Alternatively, a USB to AC adapter (or "wall charger," also included) can be connected to the cable to charge directly from an AC outlet. A number
