here’s how battery life could dramatically increase

Panasonic, one of Tesla’s main battery suppliers, is said to be developing technology to increase the density of its batteries by 20% by 2030. The autonomy of the American manufacturer’s cars could therefore soon increase significantly. .

According to a new report from Reuters, Panasonic, one of Tesla’s main battery suppliers, expects to make significant advances in battery energy density in the coming years. As a reminder, energy density is a major issue for electric vehiclessince everything depends on the performance of the battery.

Reuters announces that Panasonic aims to increase energy density by 20% by 2030. This means that a battery pack of the same size could provide longer battery life, enough to correct the biggest fault of many electric cars. This is not the first time that Panasonic has made such a promise, since already in 2020 the company had already announced that it wanted to allow Teslas to exceed 700 km of autonomy over the next 5 years.

The Tesla could soon become more enduring

By increasing the energy density of its batteries, Panasonic will be able to give car manufacturers the opportunity to increase the autonomy of their cars, but not only that. Indeed, using a battery of the same size, Tesla could actually increase the range of its Model 3 and Model Y by almost 100 kmbut the car manufacturer may not choose this option.

Increasing battery energy density would also allow Tesla to offer the same range with a smaller, and therefore lighter, battery pack. This could, for example, allow him to design a new, more compact vehicle with a long rangeor to lighten the cars currently offered in its catalog.

To achieve this 20% improvement, Panasonic would like to opt for new battery chemistry combined with another technology that Panasonic is working on. This allows in particular to slow down the degradation of a battery at a higher voltage. This is an important part of achieving its purpose, as higher voltages allow for increased energy storage capacity, but then reduce long-term battery performance. The Tesla Model Y made in Austin, Texas, could be the first to enjoy itsince it already uses Panasonic batteries.
