Tesla researchers publish work on hybrid battery enabling all-electric car range extender

Tesla, through its research arm in Canada, has published the results of research on Hybrid Lithium-Ion/Lithium Metal Cells, which can be used to create what can be best described as all-electric cars with a range extender. Typically, when we talk about electric vehicles with a range extender, we are talking about a battery-powered electric car with a small gasoline combustion engine that acts as a generator to recharge the battery when the user wants to have more range. The BMW i3 Rex is a good example. It was equipped with a battery pack enabling 126 miles (203 km) of all-electric range, which could be extended to 200 miles (320 km) with its combustion engine. Now in a new paper, Tesla’s battery research group comes up with a similar concept – but it remains all-electric. How?
