ProLogium to Unveil Next-Generation Solid-State Battery at ees Europe

ProLogium is attending ees Europe, Europe’s largest battery and energy storage technology event, in Munich, Germany, where it will unveil its next-generation solid-state battery and manufacturing technologies with industry experts. The event is also set to mark the world premiere of ProLogium’s latest breakthrough innovation called large-footprint lithium ceramic battery (LLCB) a brand new next-generation solid-state battery product.

In mid-May, ProLogium made an announcement regarding its inaugural international gigafactory for solid-state batteries in Dunkirk, France. This strategic move involves a substantial investment of €5.2 billion and aims to establish a planned capacity of 48 GWh, to be implemented in multiple phases. By selecting Dunkirk as the location for this gigafactory, ProLogium positions itself as a key player in the European EV market, as it can now engage in large-scale production of its advanced solid-state batteries while also localizing its research and development efforts and supply chain.

“With a clear roadmap for capacity ramp-up and technology development, we are making an all-out effort to accelerate the electrification revolution by providing improved energy solutions to our partners,” said Vincent Yang, CEO and Founder of ProLogium Technology.

“Last year, we announced the first solid-state battery with 100% silicon oxide anode designed to enable higher energy density at the cell level. Now, we are pleased to present the LLCB, another pioneering battery concept that will take EV battery design to the next level in terms of long-range, lightweight and design flexibility.”

New Cell Design: Optimized Range, Performance, and Sustainability

A large-footprint and high-capacity battery product, LLCB, enables a reduced number of cells and eliminates the need for parallel connections within the battery pack. This simplified pack structure not only facilitates ease of maintenance but also reduces ownership costs.

Furthermore, the LLCB’s flat shape, combined with the excellent thermal conductivity of the solid-state ceramic electrolyte, simplifies the design of the pack cooling system. This reduction in complexity optimizes the utilization of space within the battery pack.

“In other words, the LLCB will enable greater design flexibility for EVs,” remarked Simon Wu, Assistant Vice President of ProLogium Technology Product Center. “For the same space as the mainstream 2170 EV battery pack, the LLCB pack’s volumetric energy density can be nearly doubled, and for the same total energy, the LLCB pack’s weight can be cut by up to 115 kg. More importantly, the LLCB production processes will produce less waste in terms of substrate materials, and the reduced number of cells will require less raw materials, which means increased sustainability and affordability.”

Polun Cheng, Global Project Management AVP of ProLogium Technology, said “ProLogium is currently cooperating with FEV, a globally leading engineering provider in the automotive industry and internationally recognized leader of innovation across different sectors and industries, to carry out verification tests of the LLCB and design applicable solutions. Samples are targeted to be delivered to European car OEMs for testing as early as the end of 2023.”

Solid-state batteries are increasingly being advanced as a source of energy in electric vehicles. The technology solves many of the issues associated with lithium-ion batteries, and, hence, is being endorsed by many well-known brands. Recently, Toyota also announced the incorporation of high-performance solid-state batteries and other advanced technologies into their future electric vehicles (EVs) to improve driving range and reduce costs. Solid-state batteries are here to stay.
