LG Energy Solution announced on the 12th that a paper titled 'The effect of metal crystallographic texture on battery charging speed and safety,' researched in collaboration with Professor Shirley Meng of the University of Chicago, a world-renowned scholar in the field of all-solid-state battery research, has been published in the prestigious energy journal Joule.
Professor Shirley Meng developed a technology that controls the crystallographic growth direction of lithium metal by introducing a thin silicon layer into the all-solid-state battery, inducing uniform electro-deposition. She noted that this could improve the charging speed of all-solid-state batteries by more than 10 times and significantly enhance battery safety.
LG Energy Solution expects that this research achievement will accelerate the development of all-solid-state batteries without a negative electrode. These batteries operate by eliminating the negative electrode material from traditional designs and reducing lithium ions that move from the positive electrode to lithium metal at the negative electrode during charging. This method is evaluated as an innovative technology that reduces battery weight and volume while maximizing energy density. However, if lithium metal is not deposited uniformly, it can lead to reduced lifespan and performance, making a technological breakthrough essential to address this issue.
An official from LG Energy Solution said, "As demand for electric vehicles and energy storage systems (ESS) increases, manufacturing expertise and innovative research collaboration with universities are crucial for developing next-generation battery technology," adding, "We will enhance customer value and position ourselves as leaders in the battery market through continuous technological development and collaboration."
