Elon Musk’s Tesla designs an electric car battery to last 100 years

Earlier this month, the Tesla Advanced Battery Research Group in Canada published a paper stating New battery development Nickel, which can be used in electric cars. According to the study, The battery can last up to 100 years.

The electric vehicle manufacturer’s team has been working, since 2016, alongside the laboratory of specialist Jeff Dunn at Dalhousie University in Halifax.

After producing some patents and publications related to batteries, the partnership has been extended to 2026, with a focus on reducing battery costs, through a possible increase in their energy density and durability.

How will a 100-year-old battery work?

One of the basic concepts of battery life is its density., which is the amount of energy that can be stored in a volume of fuel. A high-density battery, for example, takes up less space in a car. In the case of Tesla, lithium-ion batteries of the LFP type (lithium iron phosphate) are currently used, which provide Longest interval between charges.

The new article’s proposal is specifically to increase energy density, using nickel In the chemical composition of the battery, to ensure greater autonomy. Batteries containing this transition metal have also proven to be more durable than LFP batteries. The study indicates that if a nickel battery is used at a constant temperature of 25 degrees Celsius, its life may exceed 100 years.

The study reports improved shelf life “at high temperature with di(fluorosulonyl) lithium salt (LiFSl)-containing electrolytes, far exceeding that provided by conventional LiPF6 electrolytes”. The researchers add that the benefit is occurring. Even in chemicals With little or no cobalt.
