Solid-state batteries are entering the countdown to be installed in vehicles?

Recently, automakers and battery manufacturers.

In the field of solid-state batteries, there has been a flurry of activity.

Mercedes-Benz

September 9th,Mercedes-BenzAnnounce equipped withSolid-state batteryThe pure electric EQS test vehicle has completed long-distance road testing in real-world scenarios.

With a full charge, the pure electric EQS test vehicle equipped with a solid-state battery departed from Germany and traveled across Denmark to reach Sweden.The total test distance is 1,205 kilometers.After passing through different climatic environments and road conditions, the test vehicle still had a remaining range of 137 kilometers upon reaching the destination.

This achievement breaks the record set by the VISION EQXX efficiency concept car in 2022 — traveling 1,202 kilometers on real roads from Stuttgart, Germany to Silverstone Circuit, UK.

The solid-state battery tested this time was jointly developed by the Mercedes-Benz passenger car team and the Mercedes-AMG High Performance Powertrains (HPP) team, with the expertise of F1 technology experts. The battery cells were provided by leading industry partners.Factorial EnergyProvide. ItsThe energy density has been increased to 450 watt-hours per kilogram, which can enhance the range by 25%.Mercedes-Benz'sThe goal is to put this innovative technology into mass production within 5 years.。

Volkswagen Group

On September 8, American battery companyQuantumScapeWith the battery company under the Volkswagen GroupPowerCo CompanyJointly completed the world's first.QS solid-state lithium metal batteryTest drive demonstration of the electric vehicle.

Solid-state battery

Recognized asThe next core competitive point in the battery industry

Material suppliers, equipment suppliers.

Battery manufacturers and automakers are both increasing their investments.

Racing to promote the mass production and implementation of solid-state batteries in vehicles.

Every step taken by the solid-state battery industry.

Innovations and breakthroughs in core materials are indispensable.

Single-walled carbon nanotubesAs a high-performance material, its application in solid-state battery technology significantly enhances the energy density, rate performance, cycle life, and safety of the battery.

Aluminum plastic filmThe extensibility of the material is particularly suitable for the expansion and contraction of the positive and negative electrodes during the charging and discharging of semi-solid and solid-state lithium-ion batteries.

Aluminum-plastic film is a type of multi-layer composite packaging material, usually consisting of layers from outside to inside.Nylon layer (PA), aluminum foil layer (Al), and heat seal layer (CPP/MPP)Composed through adhesive compounding, it possesses characteristics of being lightweight, highly barrier-resistant, and impact-resistant.

In the separator stage, semi-solid state batteries still retain some liquid electrolyte, thus maintaining the structure of electrolyte and separator.

All-solid-state batteries require a new type of membrane material called "skeleton membrane." Ceramic skeleton membranes are adapted to the sulfide route to enhance thermal stability.Polymeric framework membraneIt is used to support the sulfide electrolyte and alleviate the expansion problem of silicon-based anodes.
