Given the number of batteries (primarily lithium-ion) that are required to decarbonize the power and mobility sectors, the industry is now preparing for a mountain of battery waste. Recycling is technically feasible, but is also subject to sensitive economics. The framework in which recycling companies can achieve the best life-cycle costs for batteries needs to be carefully enabled through policy – and it will likely include a mixture of technologies and business models, in order to allow life-cycle emissions of batteries to be brought down.A few weeks ago, a Bloomberg interview with the chairman of Contemporary Amperex Technology, Zeng Yugun, stirred up quite a bit of media attention, causing some onlookers to rub their eyes in disbelief. Tesla’s battery supplier claims to be ready to produce batteries with a warranty for 16 years and 2 million kilometers. Hitherto, the industry standard has been around eight years and 160,000 kilometers. But nobody expects one battery pack to spend its entire life in a single electric vehicle. Already with the current warranty standard, battery packs routinely outlive the cars they are built into. Yet the million-mile battery, as it is also dubbed, isn’t going to appease the range anxiety of skeptical motorists as much as it is going to change the economics of second-life applications and the recycling of batteries.
