ProLogium presented its film-free next-gen battery tech at the 2024 Solid-State Battery Summit

25 September 2024, 15:34:58

ProLogium Technology introduced its groundbreaking battery technology – the use of a ceramic separator to replace a common polymer film separator, i.e. a “film-free” design, or also known as a next-generation platform. This film-free design, featuring a ceramic separator, equips batteries with higher energy density and fast charging capabilities. It facilitates a variety of applications and enables scalable mass production. Dr. Belov highlighted that ProLogium's lithium ceramic battery (LCB), next-generation battery technology is built on this new platform, poised to meet the urgent market demand for high-performance, safe, and cost-effective battery solutions, as this technology can accommodate more advanced materials, optimize manufacturing processes, and is applicable across various fields.

Traditionally, lithium-ion batteries are constructed with a polymer film separator between the electrodes. ProLogium, by contrast, adopts ceramic technology to replace the conventional separator, creating a safer internal battery structure. This innovation reduces the interfacial resistance among solid electrolytes, active materials, and the ceramic separator.

Thanks to its enhanced stability, this redefined structure opens a door to more advanced and diverse materials, unlocking greater potential to higher energy density and faster charging capabilities. Coupled with this design, ProLogium may leverage its patented and other advanced materials, such as silicon composite materials (SCM), ultra-thin lithium metal, and lithium-free cathode to enhance ionic conductivity and material stability to enhance performance. According to TÜV Rheinland, ProLogium’s battery is highly energy dense [Note] and capable of fast charging from 5% to 80% state of charge (SOC) in just 8.5 minutes, effectively resolving the long-standing trade-off between energy density and fast charging.

The compatibility also extends to various configurations, including all solid-state, semi-solid-state, and a wide range of module and battery pack technologies (such as BiPolar+). The next-generation platform also optimizes manufacturing processes and facilitates the direct recycling of the electrode layers within the cell, simplifying the recycling process while reducing energy consumption and environmental pollution.

ProLogium Technology received certification from TÜV Rheinland in March and May 2024, confirming the energy density of its next-generation lithium ceramic cells at 749 Wh/L (volumetric) and 321 Wh/kg (gravimetric), with a fast-charging capability from 5% to 60% in 5 minutes, and from 5% to 80% in 8.5 minutes.
