India, Oct. 7 -- The Government of India has issued a release:
A breakthrough metal-free catalyst developed by scientists could significantly reduce the cost of next-generation clean-energy technologies.
In energy storage devices such as zinc-air (Zn-air) batteries, oxygen from the air reacts with the electrode in a process known as the oxygen reduction reaction (ORR). The efficiency with which the battery operates is determined by this reaction. Zn-air batteries are a promising option for next-generation energy storage as they utilise the abundant, inexpensive and relatively safe element zinc while drawing oxygen directly from the air, thus eliminating the need to store an active cathode material. Compared with conventional lithium-ion (...
