The Inventor King and Patent Application King awards are LG Energy Solution's representative R&D reward programs, held annually to encourage a creative and challenging research and development culture within the company and to strengthen its global technological leadership.
This year, a total of 12 employees were selected: six employees who filed influential and innovative patents in the industry were named Inventor Kings, and six employees who filed multiple core patents were named Patent Application Kings. A panel of internal and external experts determined the winners through a rigorous evaluation based on criteria such as patentability, technological merit, and business potential.
The Inventor King Gold Prize was awarded to Kang Sungwook, who developed the "technology for improving the fiberization and tensile strength of dry electrodes." By optimizing the fiberization level of dry electrodes, this technology enabled the world's first mass production of dry electrodes. With this patent, LG Energy Solution has secured technological leadership and price competitiveness in dry electrode technology.
Other Inventor King technologies included: the anode-free battery with lithium-affinity material coating and oxidized anode current collector developed by Lee Jeongpil (Silver Prize); the notched aluminum tabs applied to 46 series cylindrical cans, with two or more sheets, developed by Kim Jaewoong (Silver Prize); the safety diagnosis technology for detecting micro short circuits developed by Kim Gihun (Bronze Prize); the bimodal cathode technology with a small particle crystal size of 200 nanometers or more developed by Lee Donghun (Bronze Prize); and the battery property patent technology with enhanced thermal runaway safety developed by Lee Minwook (Bronze Prize).
The Patent Application King Gold Prize was awarded to Choi Soonhyung, who contributed to a total of 19 core patent applications in the fields of battery diagnostics and lifespan improvement. Kang Kyungsoo (Silver Prize), Yoon Seoyoung (Silver Prize), Kim Jiyeon (Bronze Prize), Kim Kwangmo (Bronze Prize), and Jeong Kitaek (Bronze Prize) were also selected as Patent Application Kings.
As of last month, LG Energy Solution had secured a patent portfolio of approximately 42,000 cases and about 75,000 applications. The company has established technological advantages across the entire value chain, from materials to cells, packs, battery management systems (BMS), and manufacturing processes. LG Energy Solution plans to further enhance its competitiveness through continued investment in research and development and by encouraging talented employees.
Kim Dongmyeong, CEO of LG Energy Solution, stated, "Patents are the means by which we turn our technological capabilities into assets," adding, "We will spare no effort in investing and nurturing talent so that our members can continue to pursue creative and challenging R&D."
