Council of Scientific & Industrial Research (CSIR) lab has signed Memorandum of Agreement (MoA) with RAASI Solar Power Pvt Ltd for transfer of technology for India’s first Lithium Ion (Li-ion) Battery project. The agreement was signed by CSIR’s Central Electro Chemical Research Institute (CECRI), Karaikudi, Tamil Nadu.
CSIR-CECRI has developed indigenous technology of Lithium-ion cells in partnership with other sister CSIR labs. It has secured globally recognised patent for this technology. The indigenous Lithium-ion cells technology has potential to enable cost reduction, coupled with appropriate supply chain and manufacturing technology for mass production. Under the singed MoA, Raasi Group will set up Lithium-ion cells manufacturing facility in Krishnagiri district of Tamil Nadu close to Bangalore.
Lithium-ion battery is type of rechargeable battery that contains several cells. Each cell consists of cathode, anode and electrolyte, separator between electrodes and current collectors. In it, lithium ions move from negative electrode to positive electrode during discharge and back when charging. Li-ion battery use intercalated lithium compound as one electrode material.
Benefits of Li-Ion battery
It is light weighted and is one-third the weight of lead acid batteries. It is nearly 100% efficient in both charging and discharging as compared to lead battery which has 70% efficiency. It completely discharges i.e. 100% as compared to 80% for lead acid. It has life cycle of 5000 times or more compared to just 400-500 cycles in lead acid.
It also maintains constant voltage throughout entire discharge cycle whereas voltage in lead acid battery drops consistently throughout its discharge cycle. It is much cleaner technology and is safer for environment as it does not have environmental impact as lead acid battery. It can power any electrical application without the need of physical wires-means wireless.
