Vision & Mission
E = ms
Energy for Mobility and Stationary Storage
2
By harnessing innovative research capability to deliver commercially relevant, patent-protected & novel rechargeable batteries for the rapidly expanding energy storage market
Sodium-ion Batteries (Na-ion)
We provide safer and sustainable energy storage solutions based on sodium-ion chemistry as an alternative to Li-ion rechargeable batteries.
​
Sodium offers tremendous potential due to its ubiquitous high abundance and cost-effectiveness. We can therefore mitigate the issues of scarcity, import dependence, cost, and demand-supply ratio associated with lithium, nickel, and cobalt which all require resource-intensive mining.
​
Our proprietary hard carbon anode and symmetrical Al-Al current collector structure exhibit excellent energy storage performance. Advantages over Li-ion include zero-voltage storage/transportation, faster charging, wider temperature range, better thermal stability as well as improved storage capacity, and better cyclability.
​
‘Self-Reliance’ for energy needs is rapidly becoming essential for many countries. A domestic supply chain for all raw materials amalgamated with our end-to-end battery cell manufacturing make our Na-ion technology ideal for India, which is capable of being replicated worldwide.
