DOE Explains...Batteries

Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.

How to Solve Complicated Circuits with Kirchhoff''s Current Law …

Step 1) Reviewing everything. We have two current sources and three resistors, all with values we know. We also have two node voltages, and three branch currents that we don''t know. Let''s assume that the current through R 1 is I 1 and is flowing down, R 2 is I 2 and flowing to the left, and R 3 is I 3 and also flowing down.

batteries

However none of them are a pure "current source". You say that a battery is a "voltage source". However without a resistor attached to allow current to flow the battery cannot dissipate electrical energy, so your voltage source cannot do anything useful without allowing current to flow. The definition of current is rate of flow of charge.
