Researchers Developing Electric Vehicle Batteries To Be More Durable

Researchers at the Norwegian University of Science and Technology are finding potential ways for electric vehicle batteries to withstand minor damage, according to Green Car Reports.

Silicon-anode tech has been the center of researchers’ efforts—but they have noted that, despite it offering more energy density and range, it is prone to swell during charging and discharging, leading to long-term damage.

Introducing additional graphite has been presented as a way of achieving a stable mix. Researchers have also concocted a special electrolyte to protect the cathode and anode.

Experiments have also attempted to add binders and separators to the cell as a way to preserve the electrodes' structure, even if it’s damaged. The separators serve to keep the cathode and anode apart, preventing a short circuit. Such experiments could provide alternatives to removing entire battery packs with a few damaged cells.
