California scientists have created an organic battery water based
Engineers from the University of southern California have developed a cheap, durable battery, water-based, using eco-friendly components.
The new battery contains no metals and toxic substances. According to the author, a chemistry Professor Sri Narayana: "the Device can withstand 5000 recharge cycles, but its service life is 15 years." The concept of new batteries based on redox flow. The solutions are pumped into a cell that contains a separation membrane between two fluids with electrodes.
A team of chemists, as electroactive material, found organic compound, soluble in water. This system is cheap and allows you to create minimal impact on the environment. In the course of research, the engineers found that some natural quinones — oxidized organic compounds — fit the bill. Quinones are found in plants, fungi, bacteria and some animals, they are involved in photosynthesis and cellular respiration.
"The types of molecules that nature uses for energy transfer," said Narayan. Currently, the quinones needed for the batteries made of natural hydrocarbons. In the future, the potential exists for their production of carbon dioxide, he added.
