One of my worries has been the cost of replacing the basis as they age.
"In a paper published in the The Journal of the Electrochemical Society earlier this month, battery researchers from Halifax, Nova Scotia’s Dalhousie University describe a new lithium-ion battery that could potentially power an electric vehicle for over 1.6 million kilometres and over 4,000 charging cycles while only losing about 10 per cent of its charging capacity (and vehicle range) as it reaches the end of its lifespan."
"The teams research on improving lithium-ion batteries exclusively for Tesla, but this paper divulges exactly how they came up with a recipe for a million-kilometre electric car battery by optimising all of the ingredients, which includes artificial graphite, and then improving the nanostructure of the lithium nickel manganese cobalt oxide to create a crystal structure that’s less likely to crack and degrade performance. "
"The exact recipe allows all of Tesla’s competitors to improve their own battery tech, so what’s going on? "
"Tesla was awarded a patent for a new electric vehicle battery featuring nearly the exact same chemical makeup as the ones detailed in the research paper."
