How Does Current Source Relate to the Battery?

[huzzi.123]

How can current source be implemented? I think the source of current is the battery itself (due to potential difference). Plus current source has its own symbol. If battery is the source of current then does current source refer to the battery?

Pay particular attention to the actual definition of a current source. It is not 'just' a source of current.
