Batteries
From Production to Recycling
A battery is a portable source of chemical energy, which is converted to electrical energy as soon as the battery is placed in a circuit. The main principle is the same in almost all batteries. A metal that forms the negative terminal is opposite a positive terminal. The positive terminal is also called anode, the negative terminal cathode. Between the two terminals there is an electrically conductive liquid, the so-called electrolyte. As soon as a battery is placed in a circuit, positive and negative terminals are connected via an external contact and electrolysis takes place. On the way, a current flows from anode to cathode

The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
