Onori and her colleagues determined, however, that this is not an ideal approach for predicting the life expectancy of EV batteries — a find of particular importance, since batteries still account for about a third the of price of a new EV.
But these batteries have even higher rates of self-discharge, which is when the battery's internal chemical reactions reduce stored energy and degrade its capacity over time. Because of self-discharge, most EV batteries have a lifespan of seven to 10 years before they need to be replaced.
They then evaluated 92 commercial lithium-ion batteries for more than two years across these profiles. The more realistic the profiles, the higher the EV life expectancy rose, according to the study.
This discovery could improve the performance and life expectancy of a range of rechargeable batteries. Lithium-ion batteries power everything from smart phones and laptops to electric cars and large-scale energy storage facilities. Batteries lose capacity over time even when they are not in use, and older cellphones run out of power more quickly.
In the meantime, the company suggested combining its batteries in parallel to increase the power directed to a device. The company also plans to research the use of different nuclear isotopes in future versions of its nuclear battery, including strontium-90, promethium-147 and deuterium, which can last between two and 30 years in a device.
Their discovery could help scientists to develop better batteries, which would allow electric vehicles to run farther and last longer, while also advancing energy storage technologies that would accelerate the transition to clean energy. The findings were published September 12 in the journal Science.

The new battery, dubbed "BV100", is smaller than a coin, measuring 0.6 x 0.6 x 0.2 inches (15 x 15 x 5 millimeters), and generates 100 microwatts of power.
The battery uses carbon-14, a radioactive isotope of carbon, which has a half-life of 5,700 years meaning the battery will still retain half of its power even after thousands of years.
