Godi India manufactures 5.2 Ah 21700 cylindrical lithium-ion cells
With the use of silicon in the anode, Godi India claims an EV could achieve up to 15-20% more range, compared to graphite, on a single charge due to the increased energy density.
Godi India, the first Indian company to get BIS certification to sell lithium-ion cells made with home- grown technology, has anounced developent and manufacture of India’s first ever 5.2 Ah 21700 cylindrical lithium-ion cells with an energy density of 275 Wh/kg based on silicon anode technology.
According to the company, the electrode composition has been indigenously developed as per the market requirement. It claims that 'With the use of silicon in the anode, an electric vehicle could achieve a greater range, up to 15-20% compared to graphite, on a single charge due to the increased energy density."
Mahesh Godi, founder and CEO of Godi India said, “We are delighted to announce the manufacturing of 5.2 Ah lithium-ion cells at our Hyderabad facility. With the boom in the EV sector constituting two-, three- and four wheelers in India and across the world, the need of high energy cells have become very essential. We have already delivered 5.0Ah cells to top six OEMs in India and planning to deliver 5.2Ah cells in the near future. We believe that these high-energy density cells developed with in-house technology will be an important landmark for ‘Made in India’ for domestic and international market.”
Revealing details on future plans, Mahesh Godi said the company “is continuously innovating in the anode and cathode areas and planning to achieve >5.6Ah high-energy and high-power cells for the first time. Godi India has firmly planned for a 100 MWh pilot production facility for 5.0 - 5.2Ah cells followed by a GWh plant to cater to the requirements of the highly demanding electric two wheeler’s needs, which is more than 50GWh by 2030 exclusive for the electric two-wheeler battery segment.”
With a lithium-ion cell market size of US$ 5 billion for electric two-wheelers by 2030, silicon is the future of energy storage as it can store nearly 10 times the energy when compared to the traditional graphite anode. However, it comes with close to 400% of volume expansion during its charge and discharge process making it difficult to stabilise.
Godi India states that it has developed an eco-friendly water-based electrode manufacturing process to stabilise the silicon, which has been successfully utilized in the manufacturing of the 5.2 Ah lithium-ion cells.
Godi India is the first Indian company to enter into a public-private partnership for large scale advanced lithium-ion cells manufacturing with CSIR-CECRI.
