Then steel group Posco has entered into a cooperation with the ese solid-state battery cell manufacturer ProLogium. In addition to an undisclosed investment in ProLogium, the agreement provides for the joint development of components for ProLogium’s .
Posco is basically a steel company. However, Posco Holding has been trying to diversify its business model for several years and is therefore investing in the supply chain of battery precursors. The subsidiary Posco Chemical already has several plants in operation and under construction, and there are also important orders – for example from Ultium Cells, the battery joint venture between GM and LGES.
In the case of ProLogium, the cooperation envisages the development of anode materials, silicon cathode materials and solid electrolytes for solid-state batteries as well as the establishment of a global supply chain, according to the statement. However, details on the planned development work are not mentioned in Posco’s announcement – nor is the sum with which the Koreans will participate in the new partner.
ProLogium was founded in 2006 and has been working on solid-state batteries since 2012. Currently, they are primarily used in small devices such as smartwatches. For some years now, the focus has been on EV-compatible solid-state batteries, which is why ProLogium has also entered into a number of development partnerships in this area – including with Nio, VinFast and Mercedes-Benz. The German carmaker invested a high double-digit million amount in ProLogium this January.
