Deep dives
Evolution of Lithium-Ion Batteries
Lithium-ion batteries have evolved significantly since their introduction in the early 1990s, primarily due to their high energy density and lightweight properties. Initially designed for portable electronics, these batteries gained traction when integrated into electric vehicles, allowing for over 200 miles of range on a single charge. The technology has diversified, leading to variations like lithium iron phosphate (LiFePO4), which offers both safety and cost advantages, making it increasingly popular in the market. As manufacturers aim to reduce reliance on cobalt and seek more ethical materials, the shift towards these alternative chemistries is reshaping the landscape of battery production.
