GRIS GROUP manufactures three types of products: Mechanical components, Engineered washers, Die-cut engineered parts.

Mithieux Metal Protect offers high-performance anti-corrosion and functional coatings for metallic mechanical components, aimed at extending the lifespan of vehicles and equipment while enhancing user safety. The objectives of the E-Volution 2 project are closely tied to the development of electric vehicles (EVs), including battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs).

The functional requirements for coatings on metallic mechanical parts are evolving, necessitating a combination of anti-corrosion properties with optimal electrical conductivity and weldability. Developing a new generation of coatings that can meet these diverse challenges is strategic for the entire automotive industry, particularly for the vehicles of the future. This project has enabled Mithieux Metal Protect to develop and industrialize a tin-zinc alloy coating, establishing a high-capacity production line to meet the demands of the European automotive industry.

Their software provides accurate, real-time analysis of the state of charge (SoC) and state of health (SoH) of batteries, optimizing their performance, safety and longevity. Unlike traditional methods that require additional sensors or intensive data analysis, their approach dramatically reduces test times from days to hours, while providing detailed information on degradation mechanisms. Entroview is dedicated to promoting a sustainable energy transition. By optimizing battery diagnostics and management, they not only help reduce costs and inefficiencies, but also minimize environmental impact. Entroview’s vision is to become a key partner for companies in the battery sector, providing innovative solutions that meet today’s technological and environmental challenges.

With extensive experience in continuous processes utilizing rolls, INGECAL delivers machines dedicated to battery electrode manufacturing process such as :

– Coating line  from lab coater to industrial lines

– Calanders from lab to giga factory scale

– R&D Slitter

– Laminating machine

– Dry process lines (powder distribution, film formation, densification, laminating)

Their dynamic gap and force control system enables them to maintain a gap of +/- 0.5 µm. This system applies only the necessary force for calendering, utilizing a closed-loop control of the gap without external measuring devices, significantly reducing scrap.

They have an expertise center with 2 independent clean and dry room:

– 1 dedicated to wet process electrodes equipped with 2 calender 1 Medlab and 1 80T calander

– 1 dedicated to dry process electrodes equipped with powder mixing and calenders (film formation, densification, lamination)

CS Group develops, validates, verifies, and certifies safety and mission-critical embedded software. Their primary value to customers lies in addressing three key challenges: possessing advanced skills aligned with industry standards and cutting-edge methodologies, providing on-demand engineering bandwidth to support fluctuating product development cycles, and executing these tasks within increasingly tight budgets and schedules.

Tiamat designs, develops, industrializes and commercializes sodium-ion batteries. With its two generations (Gen1 for power applications, Gen2 for medium energy density applications), Tiamat covers electrification needs in the mobility field (road, rail, marine and air), stationary applications, off-road needs and power tool markets.

 Thanks to its patented polyanionic positive active chemistry, the Tiamat Gen1 cell is designed for high power applications (60C in discharge and charge) and ultra-fast charging solutions (<10 min). Tiamat’s Gen1 sodium-ion technology is designed for high-power applications, including mobility (48V MHEV, HEV, FCEV, BT SLI, EV backup batteries, and fast-charging EVs), stationary power storage (grid frequency regulation, UPS), power tools, and industrial use. It offers superior safety with low thermal runaway and minimal need for additional protection, and it avoids lithium, nickel, and cobalt, utilizing widely available materials refined in France. The Gen1 cell boasts a long life cycle of 10,000 high-rate cycles, making it cost-effective.

Gen2, currently in development, features a new lamellar cathode material aimed at improving energy density. With an initial density of over 140 Wh/kg, Tiamat aims for 160 Wh/kg at TRL7. Gen2 targets electric mobility (commercial and private BEVs, 2 and 3-wheel vehicles) and stationary energy storage (PV and wind farms), addressing supply and material sovereignty for future electrification needs.

Tiamat will start the construction of a 5GWh Gigafactory dedicated to the production of its Sodium-ion technology, the first volumes will be released in Q1 2026.

DeepHawk is a software solution running on-premise on off-the-shelf hardware. It increases manufacturer’s quality control performance dramatically: reducing the number of false positives from 20% to less than 1%, detecting any defects even ones that were not expected, and reducing the learning phase from several weeks down to 30 minutes. All this happens without having to hire AI experts, without interrupting the production process, without having to change existing cameras and without sending critical information out to the cloud.
