New Gen 3.5 Solid-State Battery, 381 Wh/kg Finally Goes MASS PRODUCTION!
In a significant leap for battery technology, ProLogium is set to revolutionize the electric vehicle landscape with the introduction of its new Gen 3.5 solid-state battery. With an impressive energy density of 381 Wh/kg, this groundbreaking all-solid-state cell is moving towards gigawatt-scale production, bringing new possibilities for EV enthusiasts and industry stakeholders alike.
In our latest video, we delve into the intricacies of this innovative technology, showcasing its unique features such as the ceramic solid electrolyte, silicon-based anode, and nickel-rich cathode. We explore how these advancements could enhance EV range, reduce weight, accelerate charging speeds, and improve overall battery performance.
Comparative analyses highlight how ProLogium’s solid-state batteries stack up against conventional lithium-ion batteries, particularly LFP and high-nickel variants, in aspects like charging speed, cycle life, safety, and energy density. However, we also discuss the hurdles of mass production, including manufacturing challenges and maintaining consistent quality essential for automotive applications.
As ProLogium gears up for mass production, the stakes are high. Can they meet the demands for high-volume output at competitive costs while ensuring long-term durability? This could mark a transformative shift in the future of electric vehicles.

Ceramic electrolytes sound safer, but I wonder how much more expensive these cells are compared with current high-nickel batteries.
If these batteries can deliver high energy density, fast charging, and long cycle life at a competitive price, traditional lithium-ion could have a serious problem.
This is the part of solid-state batteries I find interesting: the technology seems ready before the manufacturing process is.
381 Wh/kg is impressive on paper, but mass production is where solid-state batteries usually get complicated. I’ll believe it when we see the numbers at scale.
The big question for me is whether ProLogium can make these cells consistently for millions of EVs, not just prove that the chemistry works.
How does this compare with the latest LFP cells in real-world cost per kWh? Energy density is only one part of the equation.
381 Wh/kg could make a huge difference to EV range if the pack-level numbers are anywhere close to the cell-level figure.
I’m a little skeptical about the “mass production” claim. Gigawatt-scale capacity doesn’t necessarily mean the cells are already being produced efficiently at high yield.
If ProLogium can actually produce these cells at gigawatt scale, this could be a much bigger deal than another lab battery announcement.
The energy density is impressive, but I’m more interested in charging speed and cycle life. What good is 381 Wh/kg if the battery degrades quickly?
Good
The latest generation of LFP batteries already provides the daily range, performance and safety expected by the vast majority of consumers and costs are continuing to fall. Solid state was promoted for 2 main reasons. Firstly to fix earlier safety problems that are largely already solved. Secondly, because of future potential energy densities that are less important for most terrestial applications. Price is now the key. Today solid state will only displace LFP and sodium chemistries if the solid state technology offers lower overall prices.
YouTuber 2 bit da Vinci visited prologium factory in Taiwan and tested the battery himself, if they had started the production then it’s an excellent news 👏👏👏
