Lithium Batteries

Novel Li ion batteries for sustainable future

A rechargeable lithium battery is far more important than only energy storage. This has emerged as a mission to propel forward in the transition of sustainable future. There are far reaching impact of rechargeable Li ion technologies for environment preservation and protection for a long sustainable world ecosystem.

Invati research team is deeply engaged to invent and scale up synthesis of Lithium-iron-phosphate (LFP) batteries to achieve longer lifespan with safety. We aim to sustain an estimated 3000 to 5000 charge cycles with fast charging ability.

Few new cathode materials are under testing for fast charging using advanced rocking chair phenomenon. Another novel cathode is developed to bring more lifespan with a solid rock structure of the molecule during thousand times charging and discharging.

The anode materials are also under the rigorous research to develop nano porous graphite or other anodes.

Supercapacitor or future energy storage

We are also kept to develop Supercapacitor (SC), which is a unique electrochemical device designed to possess both high energy and power densities. When incorporated into a portable power source that relies on rechargeable batteries, it adds the capability for meeting the burst power demands in applications such as electric vehicles and power tools. Supercapacitors made from low-cost and abundant materials operating in safe aqueous electrolytes are attractive for large-scale energy storage. Owning to good safety, high ionic conductivity and low cost potentially advantageous over their organic counterparts for large-scale energy storage.

We focus on various metal hybrid nanostructures for supercapacitors with great interests for their applications in hybrid electric vehicles (EV) and backup power supplies. For such applications, it is extremely important to develop supercapacitors with higher power densities than what is currently available.
