Scientists have managed to develop a battery that offers 20 percent more range. This means you can go a lot further with an electric car than before.
Various researchers are still searching for the holy grail for batteries. How can as much energy and range as possible be extracted from a battery? Employees of the British Integrals Power have developed a new battery that can improve the range of your electric car by 20 percent.
LMFP cathode materials
It uses LMFP (lithium-manganese-iron phosphate) cathode materials, which, thanks to the breakthrough, support higher voltages and improved energy density. This is because the affordability and sustainability of lithium iron phosphate was chosen, combined with the more expensive nickel-cobalt-manganese that offers a higher energy density.
The manganese content is said to be 80 percent, while the competition often goes up to 70 percent. This higher concentration ensures that the materials reach a specific capacity of 150 mAh/g. They operate at a voltage of 4.1 V, while in traditional lithium iron phosphate cells it is common to use 3.45 V.
Patented manufacturing process
With its own manufacturing process, the company can maintain enormous capacity in the battery. It has even patented this manufacturing process. “When using traditional methods, the more manganese you add, the more the specific capacity drops and this means it cannot deliver high energy density.” (via EVmagazine)
Reason for this company to apply its own way and solve that problem, which means a breakthrough in battery technology and can be a big step in the right direction, especially for electric vehicles.
