Scientists Invent Water-Based Organic Battery

Nayaran Researchers from the University of Southern California, USA, developed a water-based organic batteries as the energy solution of the future.

Nayaran develop alternative battery along with a colleague, Surya Prakash, professor of chemistry and director of the USC Loker Hydrocarbon Research Institute and three investigators Bo Yang, Lena Hoober-Burkhardt, and Fang Wang of the USC.

These batteries were developed without the use of metal materials or toxic substances, batrai is expected to provide the benefits of energy efficiency and is able to produce more energy and to support power for electricity generation.

Batrai is more durable, as well as economic value. Narayan explains "This organic batteries last for 15 thousand mampuh replenishment cycle, expected life of 15 years,". With the capability of the cycle, the alternative batteries have a cycle of 5-fold, because the Lithium ion batteries will last in the 1000 cycle, and at a cost 10 times as much for production.

Prakash said alternative battery that will change the map of electrical energy storage, in terms of simplicity, cost, reliability and sustainability.

Batteries that reduces constraints in battery-supplied from alternative energy sources. For example, the battery generated from solar power is limited because it depends on when the turbine is shining. The condition is certainly not reliable for electricity generation. Now the battery will naturally be the solution challenges such as that experienced in the solar power plant.

"Energy storage in scale 'mega' is an important issue in the future of renewable energy. For the future requires a cheap and environmentally friendly solutions," said Narayan.

The new batteries that run the principle of redox flow, this is a similar design in a fuel cell. This stream is equipped with two tanks electroactive materials are dissolved in water.

This tank can be adjusted by the amount of energy needed to increase the energy of the system.

Mentioned key breakthrough was centered on electroactive materials. While the design of the battery before use metals or toxic chemicals, the researchers wanted to find organic compounds that can dlarutkan in water.

The system, according to researchers will create minimal impact on the environment. And on the final product will be more affordable.

Through a combination of design trial and error, the researchers found some natural quinones, organic compounds are oxidized, as required.

Quinone found in plants, fungi, bacteria and some animals. These compounds are also involved in photosynthesis and cell respiration.

"It is a type of molecule that uses natural energy to transfer," explained Narayan.

He added that so far the quinone is required for batteries manufactured from natural hydrocarbons. In the future, it is possible to get these molecules of carbon dioxide.

These findings have been dijukan in a battery design patents. The study has been published in the Journal of the Electrochemical Society June 20 issue.
