Storage Batteries Current Affairs - 2020
The researcher from Council of Scientific and Industrial Research (CSIR) has developed light carbon foam that will replace lead batteries. The carbon foam is easy to fabricate, non-toxic and affordable.
The researcher is a recipient of INSPIRE Faculty award. The material developed by the institute has the potential to replace lead-acid batteries. It is also useful to make heat sink, electromagnetic interference shielding in aerospace, electrode for lead-acid batteries, hydrogen storage and water purification systems.
The raw materials to make the carbon foam is easily available. It also helps to remove oil, arsenic and other metals from contaminated water.
Carbon Foam Batteries
The Carbon foams are porous. The pores in the batteries help increase efficiency. The micro cells completely make a new type of electrolyte structure. Hence, the power, energy and life cycle of the batteries increases.
How are carbon foam batteries better than Lead-acid batteries?
Carbon Foam batteries have better life cycle as compared to the lead-acid batteries. They are built three-fifth the cost of other advanced batteries.
India in Carbon Foam Batteries
The world’s first carbon foam manufacturing unit was set up in Gujarat in 2011. 20% of the produce in these industries are being exported and the rest are being used for electric vehicles.

The Institute of Nano Science and Technology operating under Department of Science and Technology has launched an environment friendly catalyst for rechargeable metal battery.
The Catalyst used is made of fish gills. It is low cost and can be used in energy conversion devices. The catalyst invented will overcome the bottlenecks in storage technologies such as metal-air battery, fuel cell and biofuel.
The Catalyst can be used as next generation non-precious carbon-based catalyst.
Catalysts in Biofuels
The Catalysts used in biofuel storage technologies are sodium hydroxide, potassium hydroxide and sodium methanoxide. A biofuel cells are those cells that use living organisms to generate electricity. The metal oxides used in these batteries are harmful as they cause permanent damage to tissues
Metal Air Batteries
The Metal air batteries use metals as anode and air as cathode. However, catalysts and electrolytes have hindered the development of metal air batteries.
A Fuel Cell converts chemical energy into electrical energy. Usually, platinum, a very expensive metal is used as catalyst.
