Electric cars are growing in popularity, but their limited range remains among the most frequently mentioned issues. In response to users' increasing needs, manufacturers and scientists worldwide are exploring ways to extend the distances electric cars can travel without needing a recharge. British company Integrals Power is at the forefront of this endeavour.
Range of electric cars - what it depends on and how to increase it?
The range of electric cars is one of the most important factors influencing the comfort and practicality of using such vehicles daily. The range primarily depends on battery capacity, but other factors are crucial, such as aerodynamics, vehicle weight, driving style, and weather conditions. In low temperatures, battery efficiency can decrease, causing the car to use more energy to heat the cabin.
The range can be increased by adopting several simple driving techniques, such as avoiding sudden acceleration and braking, allowing optimal energy use. Energy recovery systems that convert kinetic energy into additional power for charging the battery are also beneficial. Modern battery technologies, including new generations of cells, also contribute to extending the range of electric cars, providing increasingly higher efficiency and durability.
The British have developed a patent to increase range
In the competition to maximise the range of electric cars, British company Integrals Power has introduced an innovation that could transform this market segment. Their solution is based on next-generation cathode materials made from lithium manganese iron phosphate (LMFP). The breakthrough came with the increased manganese content in the cathode material—from 50–70% to as much as 80%. A higher manganese concentration allows cells to achieve greater capacity and efficiency.
The new cathode technology enables a capacity of 150 mAh/g at a voltage of 4.1V, which is 0.65V higher than traditional LFP (lithium iron phosphate) cells. This significant improvement can directly impact the range of electric cars, which is crucial for user interest in today's developing electromobility landscape. Using such batteries will not only increase the distance cars can cover but also their lifespan, which is important from a cost-saving perspective.
