Title: Innovations of Joseph Heelan in Lithium-Ion Battery Recycling
Introduction
Joseph Heelan is an accomplished inventor based in Worcester, MA (US). He has made significant contributions to the field of battery technology, particularly in the recycling of lithium-ion batteries. With a total of five patents to his name, Heelan's work focuses on creating sustainable solutions for battery materials.
Latest Patents
One of Heelan's latest patents involves a novel charge material for recycled lithium-ion batteries. This innovation allows for the extraction of useful elements such as cobalt (Co), nickel (Ni), aluminum (Al), and manganese (Mn) from exhausted lithium-ion batteries. The process involves dissolving the cathode material from spent cells in a solution, which contains compounds of these desirable materials. By adjusting the proportions of raw materials added to the solution, Heelan can achieve the desired ratio of commingled compounds for the recycled cathode material. This method enables the desired materials to precipitate out of the solution without the need for extensive heating or separation, thus simplifying the recycling process and maintaining the integrity of the materials.
