Electric cars, soon 600 miles possible

Innovation

 

Innolith, a Swiss company, declared to possess a new type of battery able to guarantee a mileage of up to 1,000 kilometres (600 miles) on a single charge.

Innolith, a Swiss startup, says it has successfully created a lithium-ion battery able to guarantee a mileage of 965 km, corresponding to 600 miles. The same startup claims the reason behind this  groundbreaking achievement is to be found in the use of experimental batteries that can guarantee a much higher energy density than what is currently offered by standard  lithium-ion units.

Energy density means the amount of electricity that can be stored in a given volume. Obviously, the higher the energy density, the more efficient the battery will be. This is a key aspect because, as we know, EVs biggest problems relate to the volume and weight of the battery pack. Therefore, given the same volume, using Innolith's technology, one could rely on a greater Energy density, hence extended mileage.

The Innolith battery has an energy density of 1000 Wh/kg. Compared to the lithium-ion batteries currently in use on Tesla’s Model 3 electric sedan, it is clear that the battery used by the American EV has a density of "only" 250 Wh/kg. A huge difference indeed. 

Innolith says that its batteries would be capable of powering an Electric Vehicle (EV) for over 1000km on a single charge. In addition to this, the Swiss startup says that, the Innolith Energy Battery would also radically reduce costs due to the avoidance of exotic and expensive materials used on current lithium-ion batteries. The key to all this efficiency lies in the use of a new type of electrolyte, which conduct electricity inside the battery.

Innolith still uses “wet” liquid electrolytes in its lithium-ion batteries, but there’s one major difference: the company replaces the organic (and highly flammable) solvent containing the electrolytes with an inorganic substance that’s more stable and less flammable. According to Innolith, interviewed by The Verge, the organic materials found in most lithium-ion batteries are the “principle source of side reactions,” which, over time, can consume the active materials in the battery and turn the whole closed-loop system into something “non-productive”. Innolith claims its new battery has done away with this problem.

Innolith says it will bring its innovative new battery to market via an initial pilot production in Germany, followed by licensing partnerships with major battery and automotive companies. Development and large scale commercialization will likely take three to five years, which means the company’s battery won’t be ready to go to market before 2022 at the earliest.

This innovative battery, if actually produced on a large scale, would represent a significant step forward towards the spread of electric vehicles. The Swiss company has shown itself to be very confident about the technology behind its battery, and we hope that the facts will support their statements and forecasts.
