Overview

Geely Holding has announced plans to pilot solid-state batteries in its subsidiary EV brands starting in 2027. These solid-state batteries aim to achieve an energy density of up to 500 Wh/kg, potentially enabling electric vehicles to exceed 1,000 kilometers in range and offer extended lifespan. Geely is also collaborating with Dow Chemical Company on developing adhesives for solid-state cells, strengthening its supply chain for mass production.

In Depth

Key Findings

Chinese automotive giant Geely Holding has unveiled plans to commence pilot operations of solid-state batteries in its subsidiary electric vehicle (EV) brands starting in 2027. The company states that the solid-state batteries under development are capable of achieving an energy density of up to 500 Wh/kg. This breakthrough is expected to enable EVs to achieve driving ranges exceeding 1,000 kilometers on a single charge and contribute to significantly longer battery lifespans. This strategic initiative is poised to enhance Geely’s competitiveness in the rapidly evolving EV market.

Technical / Clinical Details

The 500 Wh/kg energy density targeted by Geely represents approximately double that of current high-performance liquid-electrolyte lithium-ion batteries, promising a dramatic increase in EV driving range. Solid-state batteries, by replacing liquid electrolytes with solid materials, substantially reduce the risk of thermal runaway, thereby enhancing safety. Furthermore, they are expected to enable operation at higher voltages, leading to improved fast-charging capabilities. For the mass production of these solid-state batteries, Geely recognizes the critical importance of ‘adhesive’ technology and is jointly developing solid-state cell adhesives with Dow Chemical Company. Superior adhesive technology is essential to reduce interfacial resistance between electrodes and solid electrolytes and ensure long-term stability.

Background & Context

As the adoption of electric vehicles accelerates, battery performance and safety remain among the most critical challenges. All-solid-state batteries are considered a revolutionary next-generation technology poised to fundamentally address these issues, prompting fierce development competition among leading global automakers and battery suppliers. China, driven by its expanding EV market and robust government support, aims to play a leading role in this sector. A major automaker like Geely collaborating directly with battery material suppliers on technological development is a key strategy to accelerate vertical integration of the supply chain and secure future technological advantages. This approach enhances both the stability of battery supply and cost competitiveness.

Strategic Significance & Outlook

Should Geely successfully pilot solid-state batteries in 2027, it would significantly alleviate consumer concerns regarding EV range, thereby stimulating further growth in the EV market. Adoption is particularly anticipated in segments demanding high-performance batteries, such as long-haul trucks and luxury EVs. However, the path from pilot deployment to large-scale commercial production remains extensive, requiring the overcoming of challenges such as manufacturing cost reduction, process complexity, quality control, and stable material supply. The collaboration between Geely and Dow Chemical Company demonstrates concrete solutions to these challenges, attracting industry attention as an accelerator for the practical application of solid-state batteries.
