Title: Innovations by Arumugam Sivashanmugam
Introduction
Arumugam Sivashanmugam is a notable inventor based in Tamil Nadu, India. He has made significant contributions to the field of lithium-ion battery technology. With a total of 2 patents, his work focuses on enhancing the performance and efficiency of battery materials.
Latest Patents
One of his latest patents is titled "Process for the preparation of high voltage nano composite cathode (4.9V) for lithium ion batteries." In this innovation, an olivine structured nano-composite LiMMnPO/C was synthesized using a sol-gel assisted high energy ball mill method. This synthesis method does not require any inert atmosphere, which simplifies the production process. Electrochemical cycling studies were conducted between 3.0-4.6V using 1M LiPFin 1:1 EC/DEC as the electrolyte. The charge/discharge cycling studies of the nano-composite exhibit an average discharge capacity of 158 mAh/g at a 0.1 C rate over the investigated 50 cycles.
Another significant patent is "Cathode material and lithium ion battery therefrom." This invention describes a new high-performing lithium-ion cell that features a new carbon-based anode and dual-doped layered cathode materials. The anode is a self-standing carbon fibrous material, while the cathode is a dual-doped Lithium cobalt oxide of the general formula LiMNCoO(0.01 ≤ x, y ≤ 0.2), where M is a divalent alkaline earth metal cation and N is a divalent transition metal cation. Lithium-ion cells of 2016 coin cells were assembled using these materials, delivering a specific capacity of 60-85 mAh/g at a 1 C rate and exhibiting excellent cycling stability of 90-95% even after 200 cycles when cycled between 2.9-4.1V.
