Scientists at Chalmers University of Technology in Gothenburg, Sweden, developed a new battery material that could boost the electric vehicle range by 70%. This material is a newly invented one, named the structural battery material. It is ready to revolutionize electric vehicle production methods.

Features of this material:

• Stores energy while also serving as part of a vehicle’s structure.
• Combines functionality with reduced weight.
• Could boost the driving range of electric vehicles (EVs) by up to 70%.

How Structural Batteries Work

Battery material could boost electric vehicle range. Structural batteries are developed to reduce the vehicle’s weight, making it more compact to integrate into the vehicle’s frame. Twenty-five percent of a car’s weight is taken up by EV batteries of the traditional kind. The newly developed structural batteries are meant to replace heavy frames and panels that are non-energy-storing materials.

Material Composition and Energy Density

The battery material is made from carbon fiber composites with tensile strength comparable to aluminum. It produces an energy density capacity of 30 Watts-hours per kilogram (Wh/kg). Comparatively, traditional EV batteries such as Lithium-ion batteries (Nickel-Manganese-Cobalt) offer 150-250 Wh/kg, and Lithium-iron-phosphate batteries offer 90-160 Wh/kg.

In EV batteries, 60-75% of the weight is held by battery cells, and the remaining weight is from casing, cabling, and thermal management systems. Structural batteries eliminate the need for some components by acting as frames and energy storage.

Benefits include:

• Improved efficiency: Lighter cars require less energy to travel.
• Extended driving range: Less weight allows longer travel on a single charge.

These batteries can make laptops 50% lighter, with smartphones designed to be as thin as credit cards. Aircraft can be built lighter with frames for better fuel efficiency. However, the current energy density of structural batteries is still significantly lower than advanced lithium-ion batteries. The new battery material that could boost the electric vehicle range is set to revolutionize the field of battery storage and automaking, given it overcomes the challenges and restrictions of its prototype versions.
