Advancements in battery technology for electric vehicles (EVs) focus on improving energy density, charging speed, and longevity. Key developments include the use of solid-state batteries, which promise higher capacity and safety over traditional lithium-ion batteries. Additionally, researchers are exploring graphene and lithium-sulfur batteries, both of which aim to extend driving range and reduce charging times. These innovations are crucial for enhancing the viability of EVs, making them more appealing to consumers and accelerating the transition to sustainable transportation.
