ProLogium Gen 3.5 Lithium Ceramic Battery Enters Production

ProLogium Begins Mass Production of Gen 3.5 Battery

On September 2, ProLogium Technology began mass production of its Gen 3.5 Lithium Ceramic Battery at its Giga-level manufacturing facility in Taiwan. The battery is based on ProLogium’s Logithium cell architecture, which establishes the scalable manufacturing process associated with the Gen 3.5 design. The production start marks the transition of the Lithium Ceramic Battery technology into mass manufacturing at a Giga-level facility. ProLogium’s approach combines its cell architecture with a manufacturing process designed to support production at larger scale, providing the foundation for the company’s Gen 3.5 battery manufacturing activities in Taiwan.

Gen 3.5 Cell Delivers High Energy Density

Third-party testing provided specific performance measurements for ProLogium’s 185.4 Ah large-format cell. A TÜV test report recorded a gravimetric energy density of 381 Wh/kg and a volumetric energy density of 903 Wh/L. These measurements describe the amount of energy contained relative to the cell’s weight and volume, respectively. The results provide independently tested performance data for the large-format cell used in the Gen 3.5 Lithium Ceramic Battery technology. Together, the two figures establish the reported energy-density performance of the cell and provide measurable characteristics for evaluating the battery technology’s technical capabilities.

UL Solutions Tests Cell Under GB/T 43568-2026

UL Solutions also tested the cell using China’s GB/T 43568-2026 methodology. During the test, the 185.4 Ah cell was subjected to six hours under vacuum at 120°C. The resulting weight loss was less than 0.05%, compared with the 0.5% maximum threshold specified for all-solid-state classification under the stated methodology. This test result provides a specific measurement of the cell’s behavior under the prescribed high-temperature vacuum conditions. The comparison with the classification threshold indicates that the recorded weight loss was substantially below the maximum level used for the all-solid-state classification assessment.

Logithium Architecture Supports Scalable Manufacturing

The Gen 3.5 Lithium Ceramic Battery is built around ProLogium’s Logithium cell architecture, which defines the corresponding scalable manufacturing process. This connection between cell architecture and production methodology is central to the company’s manufacturing approach, because the battery design is being produced through a process intended for larger-scale manufacturing. The launch of mass production at the Giga-level facility therefore covers both the physical production of the Gen 3.5 cells and the application of the manufacturing architecture developed around them. The reported testing results provide technical performance and classification-related data alongside this manufacturing milestone.

Industry Impact & Outlook

ProLogium’s move into mass production gives the automotive battery sector a concrete manufacturing milestone for its Lithium Ceramic Battery technology rather than only a laboratory or development-stage result. The reported 381 Wh/kg gravimetric and 903 Wh/L volumetric energy densities could be relevant to applications where energy capacity must be balanced against battery weight and package volume, while the UL Solutions test adds independently measured evidence concerning high-temperature vacuum performance. The next important consideration is how consistently the technology performs as production scales, making manufacturing execution and continued third-party validation important factors in assessing its broader automotive significance.
