According to the International Energy Agency, a good 150 million electric cars could be on the road by 2030. This is only good for the climate if the batteries are charged with electricity from renewable sources. In addition, the components of the battery help determine how sustainable e-mobility will be. The type that dominates the market are lithium-ion batteries. They are so named because lithium ions move back and forth between the anode and cathode – this corresponds to charging and discharging. This type of battery has a higher energy density than others, which means that they can be smaller and lighter. read more / lire plus
