All car manufacturers are looking to improve the longevity and capacity of the batteries in their vehicles. Tesla, as an industry pioneer, has gone ahead and is working with researchers who have made an interesting discovery.
This is the sinews of war for manufacturers of electric cars: to ensure that the batteries are more enduring over time and able to store ever more energy. A crucial breakthrough seems to have been made by researchers at Dalhousie University in Nova Scotia (Canada), who are working with Tesla at a battery research center.
Sinews of war
The work, funded in part by Tesla, reports the development of a battery using materials different from the classic LFP (lithium-iron-phosphate) models. Thanks to a cocktail of nickel, manganese, cobalt and graphite, the researchers developed new NMC532 cells which have several characteristics worthy of interest. On the one hand, their energy density is higher than those of LFP accumulators. And on the other hand, they last longer: the capacity losses inherent in the batteries are reduced despite a large number of charge and discharge cycles.
According to the study published in the scientific journal Journal of the Electromechanical Society, these cells have a lifespan that exceeds one hundred years! Another significant advantage, this discovery could also apply to batteries that use little or no cobalt. A rare material at the origin of conflicts and synonymous with the exploitation of children in the places of extraction.
These batteries of a new kind could be used by Tesla in Powerwall, these large domestic accumulators, or even in the huge electricity storage units that the manufacturer has recently built in Australia. But it will take patience, scientific discoveries often take some time to translate into fully usable products.
