Patent Trends: Batteries for Electric Vehicles

Rapidly growing demand for the development of batteries with high capacity, lower costs, and a longer cycle life has led researchers to not only improve today's Li-ion batteries but also look toward future alternatives to today's Li-ion chemistries. As the manufacturing scale of Li-ion batteries increased dramatically over the past decade, costs fell, and today, the cost of Li-ion batteries is more closely tied to the cost of the raw materials, placing increased value on finding lower-cost materials.
