A new way of using computers, called machine learning, might make creating better lithium-ion batteries much faster and less costly. This is important because the world needs more batteries for things like electric cars and phones. Figuring out how long a new battery design will last and how it will work in real-world uses has been a slow process, holding back progress.
What Are Lithium-Ion Batteries and Why Are They Important?
Lithium-ion batteries store energy when lithium ions move between different parts of the battery. They are used in many devices, from small electronics to electric vehicles. The progress in battery technology is driving changes across many industries. Developing new battery materials and understanding how they behave has been a major challenge.
