The proportions of active material particles of certain sizes (particle-size distribution) can affect the mixing process and the quality of the electrode. Oversized or undersized particles need to be removed since they can produce dust. Also, more point contacts in active materials can cause more holes that can shrink the battery capacity.
Making a battery is a great way to get introduced to some of the basic principles of electricity. At a basic level, electricity is a type of energy that results from the movement of electrons. Batteries contain all the necessary parts to create this flow of electrons because they include an anode, a cathode, and electrolyte.
