How do batteries work?

Electricity, as you probably already know, is the flow of electrons through a conductive path like a wire. This path is called a circuit.

Batteries have three parts, an anode (-), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a traditional battery) are hooked up to an electrical circuit.

The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. You can think of this difference as an unstable build-up of the electrons. The electrons want to rearrange themselves to get rid of this difference. But they do this in a certain way. Electrons repel each other and try to go to a place with fewer electrons.

In a battery, the only place to go is to the cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode within the battery. When the circuit is closed the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit.

A new guide has been launched (in 2013) that is aimed at helping local authorities in the UK make use of new technologies, such as big data analysis and cloud computing, in order to revolutionize their local transport systems, while also reducing costs. In the current political and financial environment, where local authorities are increasingly strapped for cash, the guide illustrates how some local authorities have used technology to improve their transport systems while managing, and in some cases reducing, costs. Produced by the Institution of Engineering and Technology (IET) and Intelligent Transport Systems UK (ITS-UK), the guide sets out some of the advantages new technologies can bring in solving existing and future transport problems. Examples range from smartphone apps to determine road conditions, to Bluetooth systems that allow transport operators and planners to analyse journeys across multiple transport modes in near real-time. It also discusses some of the important issues when implementing these new solutions, including open standards, security and privacy issues

As travel and transport systems become increasingly based on internet technologies, the guide also outlines potentially dramatic changes in procurement, where traditional methods of ownership and operation can be replaced by systems that rely on cheap communications media, such as cloud-based systems.
