(ORDO NEWS) — The Tesla Research Group, in collaboration with Dalhousie University, has published a paper on a new type of battery.
Engineers talked about a nickel-based battery that promises to outperform lithium-iron-phosphate designs in every way – charging speed, energy density and lifespan.
Tesla launched its Advanced Battery Research division as part of a partnership with Jeff Dan’s lab, credited as one of the creators of lithium-ion batteries in 2016.
A group of engineers led by Dan was tasked with creating the best batteries for electric vehicles. Since then, they have designed several structures and registered a number of Tesla patents, and now began to share details about their projects.
New type batteries
A new article describes the chemistry of a nickel-based NMC532 battery that competes with LFP batteries. The developers are confident that the new battery will outperform lithium-ion batteries and offer greater energy density than the lithium-iron-phosphate combination.
Technically, this means that Tesla, if the battery prototypes confirm all engineering calculations, will be able to produce electric cars with a much longer range, but with a smaller, and most importantly, cheaper battery.
NMC532 cells, made from graphite sufficient to charge up to 3.80V, have an energy density that exceeds that of LFP cells and a lifespan well beyond that of LFP cells at temperatures of 40, 55, and 70 degrees Celsius, engineers said. in the instructions for the article.
One of the major innovations of this battery is the LiFSI-based electrolyte. This element improves the efficiency and resistance of the new battery to record levels.
The battery described in the article can last about 100 years if the ambient temperature is around 25°C. More specific specifications have not yet been disclosed – in the near future, scientists will continue to work on the design, after which they will move on to testing prototypes.
In April of this year, analysts found that Tesla was rapidly converting its electric vehicles to lithium-iron-phosphate batteries.
According to the Electreck portal, the manufacturer is now producing up to 50% of new models with batteries instead of lithium-ion batteries.
Thus, Tesla is reducing its dependence on cobalt, an expensive element needed to make popular batteries, the cost of which has increased 5 times in the last year alone.
