Philenergy said on the 1st that it will deliver its flagship equipment, a laser notching system, to a new domestic client.
Philenergy said that on the same day it won an order from a new domestic client for a laser notching system for the cathode compound section. The ordered equipment applies Philenergy's in-house developed refining technology. The technology solved problems in laser notching the cathode compound section.
In the cathode compound section notching process, handling metal spatter from the coated area during laser processing has been considered a tough problem. Philenergy's refining technology solved it by combining a blocking technique that stops spatter generated after laser cutting with a technique that removes residual spatter.
Since 2023, Philenergy has independently developed this technology and completed patent registration this year. With the client that placed the order, it also completed quality verification and cell verification.
A representative of the client introducing this equipment said, "It is a technology that overcomes the limits of the existing process," adding, "We expect the scope of application to expand significantly going forward."
Philenergy's core notching process forms tabs at the ends of electrodes. Laser notching boosts productivity by about 20% compared with the conventional blade method and can cut operating costs by more than 90%. Demand from battery cell manufacturing corporations is therefore growing rapidly.
A Philenergy representative said, "Through this equipment order, we not only secured a new client, but also laid the groundwork for greater growth based on this achievement," adding, "If the technology is adopted by the client as standard equipment, we will be able to secure new growth engines not only in existing ternary batteries but also in the solid-state battery and lithium metal battery markets."
Meanwhile, Philenergy is also in talks with another global cell maker to supply laser notching equipment applying the refining technology.
