Understanding range anxiety: the psychological barrier to electric vehicle adoption
There are multiple advantages to buying an electric car. They’re fun to drive, quiet, cheaper to maintain and better for the environment, with scientific evidence now showing that electric vehicles (EVs) emit fewer greenhouse gases and air pollutants over their lifespan than passenger cars running on fossil fuels, even when manufacturing and electricity generation are taken into account.
Supported by these arguments, and by increasingly stringent regulations accelerating the shift to low-emission mobility, electric vehicles remain central to the transition toward advanced and cleaner transportation. Yet, for many consumers, EVs are still not the default choice when buying a car. Beyond the issue of cost, which advances in battery technology and economies of scale are steadily addressing, a psychological barrier remains: range anxiety.
Improving EV battery technology
Range anxiety refers to the fear that an electric vehicle will not have sufficient driving range between charges to reach its destination. A common concern is that the typical EV range could limit long road trips or leave drivers stranded. Additional factors that may temporarily reduce battery performance, such as cold weather, stop-and-go traffic, battery aging, or intensive use of heating and air conditioning, can amplify this perception.
To accelerate mass adoption, the industry must therefore continue to find solutions to extend driving range and increase charging speed, starting with the battery.
Improvements in battery performance are part of a holistic approach to optimizing all systems at the heart of an EV, including electric motor efficiency and power electronics reliability. The future of electric mobility depends on the right combination of next-generation battery breakthroughs, higher power density, improved thermal management and lightweight components.
Some manufacturers are already exploring innovative ideas, such as integrating motors directly into the wheels. In-wheel motor designs combine the motor, inverter and brake into a single unit, increasing compactness and potentially improving efficiency and range.
Another approach is to optimize the use of dual-motor systems. Instead of distributing power from a single motor in all-wheel drive configurations, certain brands power vehicles with two motors, with potential benefits for performance, traction and energy management.

Advanced materials: enabling longer-range, safer and more efficient electric vehicles
Syensqo already supports OEMs and Tier suppliers with technologies and solutions such as high-performance polymers, thermoplastics, additives, formulations, salts, solvents and composite materials engineered for demanding EV applications. Advanced material technologies like these are essential to all the key levers that enable longer-range electric vehicles, namely battery energy density, motor efficiency, high-voltage electrical insulation and lightweighting.
In the field of battery efficiency, the objective is to increase energy density while enhancing durability, fast-charging capability and safety, including for high-voltage architectures and low-temperature operation. This can be achieved through fluorinated electrolyte ingredients that enable high-capacity anodes and high-voltage cathodes, high-efficiency fluoropolymer binders and high-purity lithium salts offering superior electrochemical and thermal stability. These advanced chemistries help extend battery life and improve performance consistency.
To reduce the size and weight of electric motors and expand vehicle range, manufacturers require efficient and lightweight materials for stator systems, connectors and busbars. Materials that optimize heat transfer and minimize electrical and magnetic losses are critical, and also support cost-effective manufacturing. High-performance thermoplastics with exceptional thermal, abrasion and chemical resistance, liquid crystal polymers designed for miniaturization and semi-crystalline polymers combining toughness, thermal conductivity and electrical insulation all contribute to more compact and efficient e-motor systems.
The same applies to power electronics. Enhancing performance through compact design, reduced weight and effective electromagnetic management is essential for developing electric vehicles that are more efficient and safer. Innovations that optimize on-board chargers, converters and inverters rely on advanced materials. For miniaturized and highly resistant connectors, rods and busbars, aromatic polyamides deliver excellent mechanical strength and thermal stability. Polymer solutions can also replace heavier aluminum or magnesium components while maintaining comparable tensile strength and modulus, contributing to overall vehicle lightweighting.
Also contributing to lightweighting are composite materials. Providing an alternative to metal, they reduce mass while offering fire resistance, corrosion resistance and improved energy absorption in the event of impact. Manufacturers can replace metal with polymers and composites in exterior parts such as rearview mirrors, wipers and door handles, as well as in structural, semi-structural and mechanical components. This strategy helps offset the weight of batteries, electric motors and power electronics, paving the way for extended driving range in both passenger cars and commercial vehicles. In addition, bonding additives applied to aluminum surfaces prior to assembly improve adhesive strength and durability, even in demanding operating conditions.
Combined, these advanced materials and technologies play an important role in helping Tiers and OEMs produce efficient, reliable and fast charging EVs. By enabling longer range, faster charging, improved safety and lighter designs, Syensqo helps make the choice of an electric vehicle an increasingly attractive one for drivers worldwide.
