ARCI signs know-how transfer Agreement with Allox Minerals
- International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), has developed indigenous technology for the production of Lithium Iron Phosphate (LFP) cathode material for Li-ion Batteries (LiBs) at its Centre for Nanomaterials.
- ARCI emphasized the importance of having a synergy among various organizations having complementary capabilities.
- ARCI and Allox Minerals, a Hyderabad-based company, signed an Agreement for Know-How Transfer on August 12, 2021.
Lithium Iron phosphate LiFePO4 (LFP):
- It is extensively used in the Lithium-ion battery field as cathode material.
key advantages of LFP:
- high current rating
- long cycle life
- superior thermal stability
- delivers a lower nominal voltage, which results in lower specific energy when compared to other cathode materials on the market.
- higher self-discharge than other Li-ion battery types.
Li-ion Batteries:
- A lithium-ion battery or Li-ion battery is a type of rechargeable battery.
- Lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications.
- In the batteries, lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging.
- Lithium-ion batteries use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode.
Advantages of Li-ion Batteries:
- High energy density
- Rate of self-discharge is much lower than that of other rechargeable cells
- Low maintenance required
- The voltage of each lithium-ion cell is higher, requiring fewer cells in many battery applications.
- No requirement for priming
Disadvantages of Li-ion Batteries:
- Contain flammable electrolytes, and if damaged or incorrectly charged can lead to explosions and fires.
- Suffer from ageing, able to withstand 500 - 1000 charge discharge cycles before their capacity falls.
- Many airlines limit the number of lithium-ion batteries they take,
- Expensive to manufacture – about 40 per cent higher in cost than nickel-cadmium.
- Requires protection circuit to maintain voltage and current within safe limits.
Applications of Li-ion Batteries:
- Electronic gadgets, Tele-communication, Aerospace, Industrial applications.
- Lithium-ion battery technology has made it the favourite power source for electric and hybrid electric vehicles.
International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI):
- It was established in the year 1997, is an Autonomous Research and Development Centre of Department of Science and Technology (DST), Government of India with the main campus at Hyderabad
- Objectives:
- Development of High Performance Materials and Processes for Niche Markets
- Demonstration of Technologies at Prototype / pilot scale
- Transfer of Technology to Indian Industry
