The development of batteries is crucial for the electric car industry.

Now researchers are building a new battery.

It could last for 100 years.

Halifax - Jeff Dahn is considered one of the most important pioneers of the modern lithium-ion battery.

Born in the US, he is a professor in the Department of Physics & Atmospheric Science and in the Department of Chemistry at Dalhousie University in Halifax (Canada).

The renowned expert has been under contract with Tesla for years.

Dahn is working on the e-car batteries of the future.

Now he and his team have apparently made new progress.

He recently published an article with other researchers in the Journal of the Electrochemical Society.

The content suggests that building a battery with a lifespan of 100 years is possible.

The authors describe a variant of a lithium-nickel-manganese-cobalt battery that is said to have a particularly long service life.

E-car with a long service life?

Researchers develop new battery

The energy storage is optimized to operate at 3.8 volts, while other nickel manganese cobalt batteries operate at 4.2 volts or more.

The lower voltage should significantly extend the life of the battery cells - according to Dahn and his team up to 100 years.

However, the use of the battery in an e-car is questionable: According to the scientists, the cell chemistry not only costs more than the lithium iron phosphate batteries that are now standard, but also does not have the performance characteristics required for operating an e-car are required.

The battery could be particularly well suited for long-term storage of energy - for example in electricity storage for excess renewable energy.

In this case, the higher costs would be worth it due to the significantly longer service life.

E-Car: Research team builds battery with high energy density

Researchers had only recently developed a fast-charging lithium-ion hybrid battery with a high energy density.

The team celebrated their discovery as a possible breakthrough for electric cars.

Lithium is a chemical element and could be obtained in Germany for millions of electric cars.

Volkswagen also relies on electric cars.

The Wolfsburg company promises advances in range.

The plans are also big in cell technology.
