In 2016, Tesla established its Tesla Advanced Battery Research division in Canada in partnership with the Jeff Dan Battery Laboratory at Dalhousie University. Dan is considered a pioneer in the field of lithium-ion battery cells. He has been working on lithium-ion batteries almost since their invention. His merit is that he helped to increase the service life of these elements, which contributed to their high prevalence in the market.
Dan's work in this area has already brought Tesla a lot of patents and scientific publications. A recent article in the Journal of The Electrochemical Society details a new type of battery cell that could be vastly superior to lithium-ion cells in use.
The article talks about batteries that use nickel, the use of which provides a higher energy density and, therefore, a longer range of electric vehicles. Interestingly, such batteries have a higher durability than lithium-ion batteries during charging at different temperatures. Theoretically, when the battery is constantly used at a temperature of 25 degrees, the battery life can exceed 100 years.
In the past, cobalt was used in the nickel battery manufacturing process. However, given concerns about the lack of this element, the researchers found that their new technology achieves the desired results and works equally well with low content or even no cobalt content in batteries.
The prospects for such batteries are not entirely clear, but Elon Musk has already paid attention to this work and has started practical work on new batteries.
