Jan 2022Undisclosed stageMercedes-Benz (lead)$112MProLogium Technology is a Taiwanese solid-state battery manufacturer specializing in next-generation EV battery cells with innovative materials and design aimed at doubling range, reducing size and weight compared to conventional lithium-ion batteries. The company has been collaborating with Mercedes-Benz since 2016 on testing EV battery cells. On January 27, 2022, Mercedes-Benz Group AG announced a strategic investment described as a high double-digit million euro amount, along with a technology cooperation agreement to jointly develop solid-state battery cells for test vehicles and potential integration into passenger vehicles by the second half of the decade. As part of the deal, Mercedes-Benz took a seat on ProLogium's board of directors to support technology development and the establishment of production capacities in Europe. The investment aligns with ProLogium's expansion plans, including completing a GWh-scale plant near Taipei by end-2022 and scaling up capacities in Asia, Europe, and the USA between 2023 and 2025. This followed a prior financing round in October 2021 where ProLogium raised over US$326 million from investors including Primavera Capital Group and SoftBank China Venture Capital, with funds earmarked for production expansion. Mercedes-Benz's move is part of its broader strategy to advance battery technology for all-electric vehicles by 2030, with other partners like Factorial Energy, Automotive Cells Co, and Farasis Energy. ProLogium also partners with VinFast. In March 2022, CEO Vincent Yang indicated plans for a potential pre-IPO funding round exceeding the prior US$326 million raise and considering listings in the US or Europe later that year or in 2023 to further support growth.
Oct 2021Series EdGav Capital; SBCVC$326MProLogium Technology, a Taiwanese solid-state battery manufacturer specializing in lithium ceramic solid-state batteries (SSBs), completed a US$326 million financing round on October 29, 2021. Investors included dGav Capital managed fund New Epoch Capital LP, Primavera managed fund Carna Investments Holding Limited, and SBCVC managed fund SBCVC Navitas Limited, with dGav Capital and SBCVC as existing shareholders providing continued support alongside new investor Primavera Capital. The company, founded 15 years prior, focuses on SSBs sold to industries like 3C electronics, industrial, medical, and IoT, and has signed strategic cooperation agreements with car manufacturers following the 2020 unveiling of its MAB (Multi-Axis Bipolar+) assembly technology. The funds are designated for developing mass production facilities for ProLogium's proprietary SSB technology and expanding plants in Asia, Europe, and the US between 2023 and 2025 to meet local demands from major OEMs for high-quality EV batteries. This investment aims to accelerate the market introduction of solid-state battery-powered electric vehicles within 2-3 years, strengthening ProLogium's position to supply high-performing, safe, and affordable EV batteries to strategic partners worldwide. CEO Vincent Yang emphasized the role of ProLogium SSBs in guaranteeing optimal safety and performance for EVs. ProLogium has previously undergone four rounds of financing with investors including SBCVC, TEDA Venture Capital Corporation Limited, and Bank of China Group Investment Limited. The round aligns with growing interest in solid-state batteries amid the expansion of the global new energy vehicle (NEV) market, positioning ProLogium to solidify its lead in mass production and commercialization of SSBs.
Apr 2020Series DBank of China Group Investment; FAW Group$100MProLogium Technology is a Taiwan-based solid-state lithium battery maker founded in 2006, specializing in next-generation lithium ceramic batteries for electric vehicles and consumer electronics.
