Samsung SDI-backed Philenergy aiming to launch 4680 battery equipment
Company preparing winders and laser notching
Battery equipment maker Philenergy is preparing to launch battery equipment aimed at 4680 cylindrical batteries, TheElec has learned.
The standard was popularized by Tesla and is being adopted by other automakers BMW, Volvo and Stellantis as well.
South Korean battery maker Samsung SDI invested 5 billion won for equity in Philenergy, a subsidiary of Philoptics, back in September 2020.
Philenergy is aiming to list on the Korean exchange next month.
Its main battery equipment being prepared for 4680 batteries is a winding machine or winder.
The equipment is used to make a jelly roll out of cathode, anode and separator.
South Korean company KOEM is effectively the sole supplier of the equipment for 4680 batteries. Its equipment is used by Tesla, Samsung SDI, LG Energy Solution and other major cylindrical battery makers.
Zhejiang Hangke and Lead Intelligent also supplied the equipment but their impact has been minimal in the market.
Philenergy has also developed new laser notching equipment. It is also planning to develop equipment for cylindrical batteries with 46mm diameters but taller lengths than 80mm such as 95mm and 120mm.
