Innolith Claims It’s On Path To 1,000 Wh/kg Battery Energy Density

The title of this post is the same as that of this article on InsideEVS.

This is the introductory paragraph.

Innolith, the Switzerland-based company with labs in Germany, announced that it is developing the world’s first rechargeable battery with an energy density of 1,000 Wh/kg (or simply 1 kWh per kg of weight). Such high energy would easily enable the production of electric cars with a range of 1,000 km (620 miles).

If they achieve their aim, a one MWh battery will weigh a tonne.

I am sceptical but read this second article on CleanTechnica, which is entitled Swiss Startup Innolith Claims 1000 Wh/kg Battery.

Innolith has a working battery at Haggerstown, Virginia, but say full production is probably 3 to 5 years away.

The CleanTechnica article, also says this about Tesla’s batteries.

Let’s put that into perspective. It is widely believed that Tesla’s latest 2170 lithium ion battery cells produced at its factory in Nevada can store about 250 Wh/kg. The company plans to increase that to 330 Wh/kg as it pursues its goal of being a world leader in battery technology. 1000 Wh/kg batteries would theoretically allow an electric car to travel 600 miles or more on a single charge.

So it would appear that Tesla already has an power density of 250 Wh/Kg.

Conclusion

I am led to believe these statements are true.

• Tesla already has an energy density of 250 Wh/Kg.
• Tesla will increase this figure.
• By 2025, the energy density of lithium-ion batteries will be much closer to 1 KWh/Kg.
• Innolith might achieve this figure. But they are only one of several companies aiming to meet this magic figure.

These figures will revolutionise the use of lithium-ion batteries.
