Lithium Electrochemical Cell with High Energy Density:

One of Roy's groundbreaking inventions is the lithium electrochemical cell with increased energy density. This design encompasses an improved sandwich cathode, wherein a high-energy-density second cathode material is sandwiched between two current collectors. This configuration allows for a high-rate discharge application, making it ideal for powering implantable medical devices. Roy's work not only enhances energy capacity but also focuses on improving manufacturing efficiency, which has significant implications for the industry.

Foil-Type Current Collector with Enhanced Design:

Another noteworthy patent from Mark J Roy is the foil-type current collector with an unperforated strip at the connector tab. This innovative design deviates from conventional current collector structures by allowing perforations to extend directly to the perimeter edge, with the exception of the area adjacent to the connector tab. By eliminating the need for a complete unperforated perimeter frame, Roy's design optimizes the overall efficiency and performance of electrochemical cells, while still maintaining the necessary structural integrity.

Contributions to Greatbatch and Wilson Greatbatch Technologies:
