On May 2, 2026, the European Patent Office (EPO) released a new report showing that patents related to battery recycling and reuse have increased more than seven-fold over the past decade. This data reflects accelerated global investment in sustainable energy and the circular economy.

Patent Growth Trend

According to EPO data, between 2016 and 2026, patent applications in the battery recycling and reuse sector grew from hundreds to thousands annually, representing an increase of more than seven times. The most significant growth areas include lithium-ion battery recycling technology, battery material reuse processes, and battery second-life application solutions.

Technology Directions

The report identifies several key innovation directions in current battery recycling technology: efficient lithium extraction technology, precious metal recovery processes for cobalt and nickel, and second-life utilization of remaining battery capacity. Advances in these technologies are significant for reducing battery production costs and decreasing dependence on critical minerals.

Market Drivers

The explosive growth of the global electric vehicle market is the primary driver behind the surge in battery recycling patents. As the first wave of widely deployed EV batteries approaches the end of their useful life, market demand for recycling and reuse has risen sharply. Governments around the world are also promoting the development of the battery recycling industry through legislation.

Industry Impact

This topic generated 119 points on Hacker News, reflecting the tech community’s interest in this trend. Analysts believe that breakthroughs in battery recycling technology will become a crucial link in the new energy industry chain, providing key technical support for achieving a circular economy. With the continued growth in patent numbers, more innovative recycling technologies and business models are expected to emerge in the coming years.
