Granted in India on May 24, 2022.
Patent is on how to use the META with Lead Acid Battery negative electrode material.
It requires mixing of a small percentage of Meta with the negative material and prepare the paste for pasting on the negative electrode.
It does not require any change in the battery manufacturing process.
Power battery test data was included that showed high current charging and discharging, validating the enhanced performance of the battery compared to normal battery.

Granted in India on January 9, 2023.
Patent is on how to prepare Meta for battery application.
It covers both Lead Acid Battery and Lithium Ion Battery.
Preparation of Meta covers slurry preparation using high surface area activated carbon, evaporation of the solvent and recovery of the evaporated solvent to reuse it for the next Meta production cycle.
This process of preparation and binding is unique.

Patent 3 is on modification over Patent 2.
Modification is for Lead Acid Battery for one binder, PTFE, and Lithium Ion Battery for removal of functional groups.
Modifications involved the following:
- Developing the temperature profile for evaporation and proper binding with PTFE for Lead Acid Battery.
- Developing the temperature profile for removal of functional groups from the activated carbon during evaporation of the solvent from the slurry for Meta production for Lithium Ion Battery.
