Liquid Battery

This world is getting older. Many energy sources are going to be depleted; we will be short of energy soon and there is no doubt about it. Alternative efficient energy sources such as solar and wind are highly unpredictable. They highly depend on forces of nature so they don’t become effective alternative of energy anymore. Many scientists take action to face the problem, including MIT professor Donald Sadoway. He is developing the first pure liquid battery that can store power for later use. He has to keep the battery in liquid form by maintain its temperature at around 700 degrees Celsius. The battery layers are created from metal alloys that are very cheap and high availability. That’s why this battery is a cheap green technology.

The battery consists of two electric pole, metal alloy, and salt electrolyte. Energy from the renewable energy source is stored in the metal alloys, and when the battery needs to supply energy, ions from one of the alloys travel through the salt electrolyte, out of the battery from the pole. Oil Company Total has invested $4 million in a joint venture with MIT for the development of a battery for homes and buildings using this technology. But researchers still have to do some further studies to understand and exploit the technology to the fullest and begin mass production at friendly costs.
