The latest development in the Hybrid / electric car battery evolution is the break through in sodium battery technology discovered by Toyota engineers. This technological break through means that the power and range of a hybrid or electric car is no longer limited to 200km on a single charge. The sodium battery is expected to provide 3 to 4 times more driving range than conventional nickel metal hydride batteries and also much smaller and more powerful. Being smaller and lighter also means the car designers have greater flexibility with car design for better aesthetics and aerodynamic efficiency.
This break through will change the way people perceive electric cars. Instead of driving the car within city limits where charging can be more accessible, the sodium battery powered electric cars will be able to drive between cities and be less of a burden to owners who wish to drive beyond 300km on a single trip. This will also make the electric cars more practical for daily use and also potentially increase the acceptance of electric cars.
The battery and driving range of the electric car has always been its Achilles heel and there was no solution for this problem until now.
