Founding and Early Years (2006–2012)
ProLogium Technology Co., Ltd. was founded in 2006 by Vincent Yang in Taoyuan, Taiwan, as an energy innovation company focused on the research and development of next-generation lithium-ceramic batteries.[10] These batteries represent a form of solid-state technology aimed at addressing limitations in traditional lithium-ion cells, such as energy density and safety concerns.[11] Vincent Yang, who serves as the company's founder, chairman, and CEO, led the initial efforts to pioneer ceramic-based electrolytes for improved battery performance.[12] From 2006 to 2012, ProLogium's activities centered on laboratory research and prototyping of solid-state lithium batteries, initially targeting applications in consumer electronics.[11] The company developed early samples of these batteries, which were supplied to automakers for testing and product development evaluation.[13] This phase involved foundational work on battery architecture, including efforts to create ultra-thin and flexible prototypes to demonstrate feasibility for integration into devices and vehicles.[14] During this period, ProLogium secured initial patents to protect its innovations in lithium-ceramic technology, building a portfolio that would later expand significantly.[15]Technological Breakthroughs and Milestones (2013–2020)
In 2013, ProLogium announced its 100% ceramic separator technology, marking the development of the world's first next-generation lithium ceramic battery that replaced traditional polymer separators with fully inorganic ceramic materials to mitigate risks associated with liquid electrolytes, such as leakage, flammability, and dendrite-induced short circuits.[16][17] This breakthrough enhanced thermal stability, enabling operation at temperatures up to 110°C without degradation, and supported initial shipments to customers in the consumer electronics sector for validation in portable devices.[16] By 2017, ProLogium achieved fully automated production on its G1 line with a capacity of 40 MWh per year, demonstrating scalable manufacturing of lithium ceramic batteries while entering explosion-proof markets for industrial applications requiring high safety margins.[16] The company's Multi-Functional Cell earned a CES Innovation Award that year, highlighting its versatility in form factors for diverse uses.[16] A pivotal advancement came in 2018 with the announcement of BiPolar+ technology, a bipolar cell architecture that integrates electrode layers without external tabs or busbars, reducing overall pack weight by up to 50% compared to conventional tabbed designs and improving thermal management through uniform current distribution and inherent heat dissipation.[16][18] The Solid Lithium BiPolar Cell received the CES Innovation Award, validating its potential for higher energy density at the pack level, with projections of 340 Wh/kg post-pack integration.[16] In 2019, ProLogium introduced MAB (Multi-Axis BiPolar+) technology, extending BiPolar+ to multi-directional stacking for further optimization of space and efficiency, alongside completing lithium ceramic battery (LCB) sample integrations into vehicles in Asia for real-world testing of range and safety.[16] BiPolar+ also secured the Gold Edison Award and another CES Innovation Award, underscoring peer recognition for its empirical gains in gravimetric energy and reduced material usage.[16] The period culminated in 2020 with the completion of the G2 production line, scaling capacity to 0.5–2 GWh annually and signaling readiness for mass production of solid-state lithium ceramic batteries, bolstered by a $100 million Series D funding round to fund commercialization and facility expansion.[16][14] This investment, led by investors including FAW Group and BOCG, targeted acceleration of bipolar-integrated cells toward automotive volumes while maintaining focus on ceramic-based safety architectures.[19]Recent Developments and Global Expansion (2021–Present)
In January 2022, ProLogium entered a technology cooperation agreement with Mercedes-Benz, under which the automaker invested a high double-digit million euro amount and the parties committed to jointly developing next-generation solid-state battery cells for electric vehicles.[20][21] At the 2022 Paris Motor Show, the company debuted its next-generation solid-state battery technologies, including lithium ceramic batteries (LCB), highlighting advancements in energy density and safety.[22] In May 2023, ProLogium announced plans for its first overseas gigafactory in Dunkirk, France, with a €5.2 billion investment targeting 48 GWh annual capacity in three phases, aimed at supporting European supply chain diversification amid geopolitical tensions over reliance on Chinese battery production.[23][24] Construction permitting advanced, with environmental and building approvals secured by January 2025, though the company indicated a gradual ramp-up in response to slower-than-expected European EV demand.[25][26] ProLogium achieved TÜV Rheinland certifications in March and May 2024 for its LCB energy density at 749 Wh/L volumetric and 321 Wh/kg gravimetric, followed by a December 2024 update confirming record levels of 811.6 Wh/L and 359.2 Wh/kg.[27][28] In October 2024, at the Paris Motor Show, it unveiled the world's first 100% silicon composite anode battery pack in partnership with FEV Group, achieving 749 Wh/L system density with projections to 823 Wh/L by year-end and enabling 5-60% charging in 5 minutes.[15][29] By the first half of 2025, ProLogium reported shipments exceeding 2.4 million next-generation LCB units, with 21% from its Taoyuan gigafactory.[30] At CES 2025, it revealed a fully inorganic electrolyte LCB variant supporting 5-80% charging in 8.5 minutes and adding up to 600 km range in 10 minutes.[31][32] In August 2025, at IAA Mobility, the company outlined European mass-production timelines tied to the Dunkirk facility and signed an MoU with Rimac Technology for further collaboration.[33][34]Technology and Innovations
Core Battery Architecture: Lithium-Ceramic Solid-State Design
ProLogium's lithium-ceramic solid-state battery architecture centers on a fully inorganic design utilizing oxide-based ceramic electrolytes and separators, eschewing the organic liquid electrolytes prevalent in traditional lithium-ion cells. This configuration leverages the inherent non-flammability of inorganic ceramics to eliminate the propagation of thermal runaway, a failure mode triggered by electrolyte decomposition and oxygen release from cathodes under stress in liquid systems. Ceramic materials maintain structural integrity and flame resistance even under extreme heating, as demonstrated in comparative tests where only all-ceramic electrolytes avoided combustion throughout prolonged exposure.[35][36] The solid-state ceramic separator acts as a robust barrier, preventing electrode contact and short-circuit initiation during mechanical deformation or volume changes in electrodes, which contrasts with porous polymer separators in liquid batteries that can fail under similar conditions. This design supports high-temperature operation—up to levels where liquid electrolytes would volatilize—while enhancing overall durability by blocking pathways for reactive species migration. ProLogium's superfluidized all-inorganic electrolyte further integrates these properties, enabling uniform ion transport without the brittleness issues plaguing some oxide ceramics.[37][35] In addressing dendrite formation—a common lithium-metal challenge where metallic filaments pierce electrolytes—the solid ceramic matrix provides mechanical suppression, with its dense structure resisting penetration better than liquid media, though full mitigation requires optimized interface engineering. ProLogium reports empirical cycle life exceeding 900 iterations under fast-charging protocols (10-80% state-of-charge in minutes), attributing this to the electrolyte's stability against dendrite-induced degradation, though independent third-party validation of these figures remains forthcoming as of 2025.[17][38][39]Key Proprietary Technologies (BiPolar+, LLCB, and Silicon Anodes)
ProLogium's BiPolar+ technology employs a proprietary bipolar electrode stacking architecture that integrates series-parallel connections directly within the cell structure, eliminating the need for external tabs and wiring typically used in conventional lithium-ion batteries. This design reduces internal resistance by minimizing conductive pathways and contact points, enabling efficient current flow and higher operational voltages at the cell level. By facilitating a three-dimensional (3D) multi-axis configuration, BiPolar+ supports pack-level integration where multiple cells form a unified structure, thereby decreasing the proportion of inactive materials like casings and interconnects, which contributes to overall weight reduction in battery packs.[37][18] The Large-Footprint Lithium Ceramic Battery (LLCB) builds on BiPolar+ by scaling the electrode footprint to dimensions suitable for electric vehicle (EV) applications, such as cells exceeding traditional pouch formats to achieve capacities in the range of tens to hundreds of ampere-hours per unit. This large-format approach leverages the ceramic solid electrolyte's inherent stability to maintain structural integrity under mechanical stress, allowing fewer but larger cells to deliver equivalent total energy while reducing assembly complexity and material overhead at the module and pack levels. Consequently, the volumetric energy density of LLCB packs approaches twice that of comparable liquid-electrolyte systems, primarily due to minimized void spaces and enhanced space utilization in the stack. ProLogium introduced LLCB publicly in June 2023, emphasizing its role in enabling scalable production for automotive integration.[40][41] In October 2024, ProLogium unveiled a 100% silicon composite anode technology, replacing conventional graphite with silicon-based materials that offer a theoretical capacity over ten times higher due to silicon's ability to alloy with lithium at a 4.4:1 ratio by mass. To mitigate silicon's volume expansion (up to 300% during lithiation) that can cause pulverization and capacity fade, the composite incorporates proprietary nanostructures and coatings—protected by interfacial resistance patents—to maintain electrode cohesion and electrolyte compatibility. This anode integration with ProLogium's lithium-ceramic framework achieves projected gravimetric densities up to 380 Wh/kg at the cell level without introducing dendrite risks or compromising cycle life, as the solid ceramic separator provides mechanical suppression of irregularities. The technology debuted at the Paris Motor Show, marking a shift toward anode-limited performance in solid-state designs.[15][42][29]Performance Claims: Energy Density, Safety, and Charging Capabilities
ProLogium's lithium-ceramic batteries have achieved certified volumetric energy densities of up to 811.6 Wh/L and gravimetric densities of 359.2 Wh/kg, as verified by TÜV Rheinland testing in December 2024, surpassing earlier 2024 metrics of 749 Wh/L and 321 Wh/kg.[28][43] Fourth-generation cells reach 860.6 Wh/L volumetric and 356.3 Wh/kg gravimetric, representing improvements over conventional lithium iron phosphate (LFP) and nickel-manganese-cobalt (NMC) baselines through third-party evaluation, though real-world pack-level densities may vary due to integration factors.[43] These figures position the technology ahead of typical liquid-electrolyte lithium-ion cells, which often fall below 700 Wh/L at the cell level, enabling potential for extended vehicle range without proportional mass increases.[43] Safety performance emphasizes prevention of thermal runaway via non-flammable ceramic electrolytes and active mechanisms that isolate faults, with TÜV Rheinland confirming no ignition or propagation in abuse simulations.[28] In penetration tests, such as bullet impact, cells exhibit minimal temperature rise (1.5°C) without smoke, sparks, or combustion, contrasting with liquid-electrolyte batteries prone to exothermic reactions.[44] ProLogium attributes this to dual intrinsic (material-level non-combustibility) and active (structural isolation) protections, countering overstated risks in some solid-state designs lacking such redundancies, though independent long-term fleet data remains limited.[35] Charging capabilities include 5% to 80% state-of-charge in 6.4 minutes for fourth-generation cells under 400V systems, with TÜV-verified rates of 8.5 minutes for prior generations and retention of 80% capacity after 800 fast-charge cycles (5 minutes each).[43][45] Low-temperature operation outperforms standard lithium-ion batteries, maintaining discharge rates above industry norms at sub-zero conditions due to stable ionic conductivity in the ceramic matrix, reducing degradation from lithium plating.[43] These metrics suggest viability for high-utilization applications like electric vehicles, though sustained performance depends on system-level cooling and cycle depth in deployment.[45]Products and Applications
