Rechargeable Batteries
GS- Paper-3 S&T (PT-M-IV)
Recently, the United Nations Conference on Trade and Development (UNCTAD) released a report ‘Commodities at a glance: Special issue on strategic battery and minerals’. The report facilitated research into battery technologies that depended less on critical raw materials and had the potential to provide higher energy density. Energy density is the amount of energy that can be stored in a given mass of a substance or system, i.e. a measure of storage of energy.
Imp Points
Uncertain Supply: The report highlighted that the supply of raw materials to produce rechargeable batteries is uncertain. Lithium, natural graphite and manganese are critical raw materials for the manufacture of rechargeable batteries.
Rising Demand: Integration of EVs- There has been a rapid growth in demand for rechargeable batteries due to the gradual integration of electric vehicles (EVs) in global transportation. The sales of electric cars have increased by 65% in 2018 from 2017 to 5.1 million vehicles and it will reach 23 million in 2030.
Increased Use of Raw Material: With the increasing number of EVs, the demand for rechargeable batteries and the raw materials used in them have also increased. The worldwide market for cathodes for lithium-ion batteries was estimated at $7 billion in 2018 and is expected to reach $58.8 billion by 2024.
The demand for raw materials used to manufacture rechargeable batteries will grow rapidly as other sources of energy lose their importance.
Li-ion Batteries
Alternative sources of energy such as electric batteries are becoming more important as investors become sceptical of the future of the oil industry. There is a need to make a strategy for dynamic monitoring of the raw material cycles, from mining through processing, refining and manufacturing to recycling. It will facilitate early detection of supply risks and also enable the development of mitigation strategies at either company or national level.
