Elon Musk’s Tesla Designs Electric Car Battery to Last 100 Years

Tesla’s advanced battery research group in Canada earlier this month published a paper in which it reports on the development of a new nickel-based battery that can be used in eletric cars. According to the study, the battery can last up to 100 years.

The electric vehicle manufacturer’s team has been working since 2016 together with the laboratory of specialist Jeff Dahn at Dalhousie University in the city of Halifax.

After the production of some patents and publications on batteries, the partnership was extended until 2026, with a focus on reducing battery costs, via a potential increase in their energy density and durability.

How will the 100 year old battery work?

One of the key concepts for battery life is its density., which is the amount of energy that can be stored in a volume of fuel. A battery with higher density, for example, takes up less space in the vehicle. In Tesla’s case, lithium-ion batteries of the LFP (Lithium Iron Phosphate) type are currently used, which offer a longer interval between charges.

The proposal of the new article is precisely to increase the energy density, using nickel in the chemical composition of the battery, to ensure greater autonomy. Batteries with this transition metal also proved to be more durable than LFPs. If the nickel battery is used at a constant temperature of 25ºC, its lifetime could exceed 100 years, the study states.

Improved shelf life “at high temperature is demonstrated with electrolytes containing lithium bis(flurosulonyl)mide salt (LiFSl), well beyond those provided by conventional LiPF6 electrolytes,” the study states. The researchers add that the benefit occurs. even in chemicals with little or no cobalt.
