Bumpy electrode makes for smooth battery operation at sub-zero temps
As the source of power for electric cars and many other modes of clean transportation, improvements in battery technology stand to benefit vehicle performance in a number of important ways. This includes not just range figures but how well they can operate in colder climates, as new research detailing a promising sub-zero battery design demonstrates.Extreme temperatures that approach freezing can be quite problematic for lithium-ion batteries and lead to substantial power losses. In the context of electric vehicles, this…
