ProLogium says it will start shipping its solid state silicon battery to European car makers for testing by the end of this year.
The new solid state battery design with a ceramic electrolyte can nearly double the energy density of an EV pack while significantly reducing its weight and the number of cells in pack with increased cell energy says the company.
The Large Lithium Ceramic Battery (LLCB) format reduces the number of cells and the number of parallel connections in the battery pack, reducing component and assembly costs. The flat shape and the excellent thermal conductivity of the solid-state ceramic electrolyte combined can make the design of pack cooling system much less complex, thereby optimizing space and saving over 100kg.
“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, light weight and design flexibility,” said Vincent Yang, CEO and founder of ProLogium Technology.
“ProLogium is currently cooperating with FEV 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,” said Polun Cheng, Global Project Management AVP of ProLogium Technology. European partners include Mercedes-Benz.
ProLogium is setting up its first overseas solid-state battery gigafactory in Dunkirk, France, in a €5.2bn investment. The total planned capacity of 48 GWh will be deployed in phases to supply the European EV market. “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 Yang.
“The LLCB will enable greater design flexibility for EVs,” said Simon Wu, Assistant Vice President of ProLogium Technology Product Centre.
“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,” he said.

French startup InjectPower is looking to set up a fab to build solid state batteries for medical applications.
The company has developed a miniature solid state lithium ion battery technology that can be used in implanted devices. The battery cells are 0.1mm thick with a footprint of 1mm2. The key is that the batteries can be built on a 200mm wafer process with deposition, etch and passivation, and the company is currently looking for a site for a cleanroom to be up and running in 2026.
The prototype devices have been made on the 200mm pilot line at CEA-Leti in Grenoble, showing an energy density of 250Wh/l. This currently has a yield of 50%, although the new cleanroom would see the yield increasing to 80- to 90%. A single 200mm wafer would produce 10,000 of the batteries, so a few hundred wafers would supply the predicted demand.
As a result the company has worked with US startup InjectSense which has developed a MEMEs pressure sensor, controller ASIC and wireless charging chip. These would be combined with the batteries for long-term monitoring of intra-ocular pressure (IOP) in the eyeball. This assesses the effectiveness of glaucoma treatments.
