Title: Innovations of Jung Ho Lim in Battery Technology

Introduction

Jung Ho Lim is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of battery technology, particularly in the development of positive electrode active materials for secondary batteries. With a total of three patents to his name, Lim's work is pivotal in advancing energy storage solutions.

Latest Patents

One of his latest patents is a method for preparing a positive electrode active material. This method involves several steps, including adding a reaction mixture containing a lithium raw material and a nickel-manganese-cobalt precursor into a first crucible. The mixture undergoes a first heat treatment at a temperature of 500-800° C. to form a pre-sintered mixture. The pre-sintered mixture is then extracted, pulverized, or classified before being subjected to a second heat treatment at a temperature of 700-1000° C. under a controlled atmosphere. This process results in a lithium nickel-manganese-cobalt-based positive electrode active material, with a significant reduction in volume after the first heat treatment.

Another notable patent involves a positive electrode material for a secondary battery and a method of making the same. This invention includes a lithium composite transition metal oxide that contains nickel, cobalt, and manganese, with nickel comprising 60 mol % or more of the metal content. Additionally, a coating layer formed from a lithium-polymer compound enhances the performance of the positive electrode material.
