Fish Gill-based Electro-catalyst

Scientists at INST have developed a low cost, bio-inspired electro-catalyst from fish gills for use in energy conversion devices. Electro-catalyst Catalyst is a compound that alters the rate of a chemical reaction without itself being consumed during the process. An electro-catalyst is a catalyst used to alter the rate of electro-chemical reactions. Traditional electro-catalysts are ..

Lithium-Ion Battery Cell

A lithium-ion battery cell  is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an  intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell. Indian Space Research ..
