According to foreign media reports, on August 20, 2024, South Korean battery supplier LG New Energy announced that its advanced dry electrode process pilot production line is about to be completed.
The new pilot production line is installed at the company’s Ochang Energy Plant and is expected to achieve full production by 2028.
, It is reported that LG New Energy has developed a unique dry electrode process that may surpass all other processes.
LG New Energy estimates that its unique dry electrode process can reduce battery manufacturing costs by 17% to 30%.
Currently, in the electric vehicle market, the dry electrode process has become a widely used battery manufacturing method that does not require drying of foils coated with mixed active materials and organic solvent slurries.
According to South Korean media reports, since the drying process usually requires the use of ovens with temperatures exceeding 200 degrees Celsius, it consumes a lot of space and energy.

Last month, Cole Otto, Tesla’s senior manufacturing engineer responsible for the development of the 4680 battery, shared a photo of Cybertruck, an electric pickup truck equipped with a 4680 battery that uses a dry cathode.
Otto said Tesla’s dry cathode 4680 battery is “an important milestone in technological and cost-efficiency progress.
” LG New Energy’s dry electrode process may bring about advances in battery technology and cost-effectiveness.
The South Korean battery manufacturer’s dry electrode process is different from other processes in that it can be used on both the anode and cathode of a battery.
In contrast, most dry electrode processes only focus on the anode or cathode, and cannot do both.
, LG New Energy has developed technology that can improve electric vehicle batteries, which could benefit Tesla and other automakers that have partnerships with the South Korean company.
In addition, LG New Energy also produces 4680 batteries at its Ochang factory, with the goal of achieving mass production in the third or fourth quarter of this year.
