Salt Can So Disposable Batteries

Chunks of salt blocks that looked wet and damp may seem unattractive to be seen and used to add an ingredient in cooking.

But if you cut and stacked in such a way, the salt can produce a number of energy resources that can make you impressed.

This discovery later became sufficient knowledge for scientists in Sweden to create a salt-based batteries and paper that can produce electrical energy by one volt.

They hope, at least battery power is not too big one day can provide power for biodegradable sensors or sensors that can be destroyed by bacteria.

"We want to make a very simple battery and use the same material in both electrodes," said Professor Leif Nyholm from Uppsala University, Sweden was quoted as saying by ABC News, Monday (19/10/2009).

"To make it simple, we just put that NaCl is a salt compound in the second battery electrode," he added.

Batteries Nyholm and his team created a paper-thin size. But the battery is made of many layers of cellulose is encased in a conductive polymer 50 nanometers thick and sandwiched between layers of filter paper.

Then, a little water will help the chlorine ions leads to the negative electrode while the electrons toward the positive electrode.

The entire battery assembly with a thickness of only a few millimeters was wrapped in plastic. According to Nyholm, more and more piles of salt, the greater the power generated.

Nyholm also mention, battery salt and this paper does not have the power of batteries made from lithium, cobalt or nickel. But according to him, this battery can recharge the energy faster.

That is why, this battery can not be used for laptop or mobile phone. Battery that is environmentally friendly components are more suitable for devices such as sensors that monitor temperature and humidity.
