Posco to supply ProLogium with solid-state battery materials

Yusin Hu, DIGITIMES, Taipei 0

South Korean steel manufacturer Posco has entered into an agreement with Taiwan-based solid-state battery developer ProLogium to supply cathode, anode, and solid electrolyte materials, according to the EV battery maker.

As ProLogium prepares to start mass-producing solid-state battery for EV by 2023, it has partnered with the South Korean steel maker to secure material supply. According to an official announcement, Posco is investing over double-digit millions in US dollar in ProLogium's solid-state battery manufacturing.

"Posco Holdings will continue to expand its secondary battery portfolio and strengthen its competitiveness in next-generation materials through cooperation with innovative companies such as ProLogium," said Kyungsub Lee, chief of LiB Materials Business of Posco Holdings.

Posco plans to mass produce solid electrolyte in the second half of 2022 through a joint venture Posco JK Solid Solution established by Posco Holdings and a Korean solid electrolyte material manufacturer Jeong Kwang (JK).

Posco is also strengthening its connection with tier-one carmakers in the North America through subsidiary Posco Chemical, which produces battery materials.

ProLogium announced earlier this year that it has partnered with Mercedes-Benz and Gogoro to supply solid-state batteries for premium EVs. The company has revealed it is building production capacity to start mass producing next-generation batteries for cars that demonstrate enhanced safety and higher performance.

ProLogium CEO Vincent Yang expects demand for solid-state battery to grow in the coming years.
