Evolution of Lithium-Ion Battery Lifecycles: Key Industry Insights

Hans Eric Melin, Managing Director at Circular Energy Storage, recently shared valuable insights in a LinkedIn post about the shifting lifecycle of lithium-ion batteries. Melin highlights a significant change in how long these batteries last, stating, “Of the lithium-ion batteries that were placed on the market in 2020, only 35.4% will have reached end of life after ten years.” This is a sharp contrast to the 80% seen with batteries placed on the market in 2010. By 2040, Melin projects that “less than 21% of the batteries placed on the market 10 years prior, will have reached end of life.”

This trend is not just a result of better battery technology but also reflects a shift in battery applications. “In 2010, over 98% of the batteries placed on the market were used in portable applications,” he explains. By 2020, however, portable batteries accounted for less than 20%, while light and heavy electric vehicles (EVs) made up 62%. Since EV batteries are designed to last longer, and the vehicles themselves have a longer lifespan compared to consumer electronics, this has a profound effect on when batteries are retired.

Melin also touches on economic and behavioral factors. “While $2,500 for a 13-year-old Nissan Leaf or Mitsubishi i-MiEV is not a lot for a car, it’s still a substantial sum of money,” he notes. As long as these vehicles meet basic requirements, they stay on the road, delaying the need for recycling or reuse of their batteries.

As battery lifecycles lengthen due to improved applications and longer-lasting technologies, fewer batteries will reach end-of-life as quickly as they did a decade ago. This poses both challenges and opportunities for the recycling industry. Proper battery recycling reduces the strain on natural resources and helps manage the growing demand for materials like lithium, cobalt, and nickel, which are crucial for the future of energy storage. As Melin’s work at Circular Energy Storage shows, understanding the lifecycle of these batteries will be essential in shaping policies and business models that drive sustainable energy solutions forward.
