LG Energy Solution (373220) plans to commercialize all-solid-state batteries using its advanced dry electrode technology.
According to industry sources on the 18th, LG Energy Solution will commercialize graphite-based all-solid-state batteries for electric vehicles by 2029 and anode-free all-solid-state batteries for humanoid robots by 2030.
Graphite-based all-solid-state batteries utilize conventional graphite anode materials, offering advantages in structural stability and mass production capability. The anode-free approach uses only current collectors without anode materials, maximizing energy density per volume. This technology is considered optimal for extending operating time in humanoid robots, where space constraints are severe.
LG Energy Solution plans to secure core competitiveness in all-solid-state batteries through its dry electrode process. The dry process eliminates organic solvent drying steps, dramatically reducing equipment investment and processing costs. Industry experts regard it as a next-generation method that shortens manufacturing time while improving space efficiency.
LG Energy Solution has filed more than 450 dry electrode-related patents worldwide. The company holds key patents for "dry electrode fibrillation and tensile strength improvement technology," which is essential for mass-production-grade dry electrode manufacturing. The technology requires high expertise as it can be applied to both cathodes and anodes regardless of active material particle size. It also covers the technically challenging lithium iron phosphate (LFP) cathode dry process.
"We completed the setup of a dry electrode pilot line at our Ochang Energy Plant last year. This year, we will focus on securing mass production capability for our existing LFP dry cathode," an LG Energy Solution official said.
