ProLogium Technology is showing its solid state battery with 100% silicon anode for the first time at the Paris Motor Show this week.

The company was in Paris earlier this year as one of the sites for battery gigafactory and has a technology cooperation agreement with Mercedes-Benz to develop next-generation EV battery cells.

“It’s imperative for ProLogium to be part of the global mobility community with our participation at the Paris Motor Show 2022. With our innovations to be presented at the show, ProLogium has once again proved its ability to imagine, design and develop breakthrough technologies that enable sustainable mobility,” said Gilles Normand, Executive Vice President of International Development at Taiwan-based ProLogium.

For lithium ion batteries with liquid electrolytes, silicon rarely takes up more than 10% of the anode composition due to safety concerns caused by silicon swelling. The ProLogium cell is the first to use an anode built of 100% silicon oxide which increases energy density to 295-330 Wh/Kg, or 695-770 Wh/L. This will be available in 2023 Q1 as prototype samples.

ProLogium says it is now ready to scale production of lithium ion cells for electric vehicles, and is planning an $8bn gigafactory. Shortlisted locations include those in the United States, France, Germany, the Netherlands, Poland and the United Kingdom, with the decision set to be announced in Q1 2023.

The plan is for three phases of construction for the gigafactory, starting with a capacity of 3GWh. The total capacity is expected to reach 120GWh when the plant is complete. By 2031, the project will create over 6,500 jobs, and the company is poised to begin its global talent recruitment efforts in the areas of engineering, product research and development, business management, and more.

The battery maker owns proprietary technologies covering over 500 (applied or awarded) patents worldwide and has established more than 4,000 quality control items in its production processes, achieving 99.9% yield for its single-layer cell manufacturing and 94% yield for multi-layer cells.

The company has already shipped more than one million cells for consumer electronic applications (from 15mAh to 1Ah) and has started the testing and certification process with key global car OEMs by delivering nearly 8,000 EV battery cells (50~60Ah).

“Our first-ever overseas gigafactory serves a key strategic purpose – being close to our customers to deliver products and services in a timely manner,” said Vincent Yang, CEO and Founder of ProLogium Technology.

“The United States and Europe play a crucial role in the global automotive industry value chain. Automakers are accelerating their plans to extend their EV product range. With manufacturing bases in these regions, we will be able to better meet the market’s needs and benefit from local policy support. The proximity allows for local production and local supplies, planting closer to customers to reduce carbon footprint – a win-win solution for the benefit of both our customers and ProLogium.”

Paris discussion

“In Paris, we discussed next-generation battery technology breakthroughs with French President Emmanuel Macron at a face-to-face meeting during the Choose France Summit and presented our overseas expansion plans and leading advantages in technology and mass production. Both the US and French governments expressed their full support for ProLogium to set up plants locally, an indication of the increasing strategic importance of the next-generation battery,” he said.
