EV Battery Second Life & Recycling
Retired EV batteries still have a lot of useful life left - and utilities are increasingly willing to use them for grid storage rather than sending them straight to recycling. This report covers market sizing, China's early lead in both reuse and recycling, and segments by application and end-of-life pathway while mapping the logistics and recovery landscape.

Overview
The EV battery second-life and recycling market is projected to grow from $15.4 billion in 2025 to $46.9 billion in 2035 at an 11.8% CAGR, driven by rising EV sales, recycling regulations, critical mineral prices, and OEM net-zero commitments. The EU Battery Passport becomes mandatory for EV and industrial batteries above 2 kWh from 18 February 2027, with minimum recycled-content requirements of 16% cobalt, 6% lithium, and 6% nickel taking effect from 2031 under EU Battery Regulation 2023/1542. China leads EV battery recycling and reuse globally, while the DRC supplied over 70% of global cobalt in 2024 and China controls approximately two-thirds of lithium refining, creating structural supply risks for non-Chinese players. The utilities and grid operators segment is forecast to grow from approximately 24% of second-life end-use demand in 2025 to 42% by 2035, as second-life capacity is projected to rise from 25-30 GWh in 2025 to 330-350 GWh by 2030.
Key points
- Global lithium-ion battery demand is expected to rise from around 700 GWh in 2022 to about 4.7 TWh in 2030, with approximately 4,300 GWh used in mobility, creating a large wave of EV batteries that will require second-life or recycling solutions in the 2030s.
- Traditional state-of-health battery testing takes 3-6 weeks and costs $200-$500 per battery, while AI-driven diagnostics can reduce assessment time to hours at under $50 per unit; in 2025 pilots, AI diagnostics improved profitable second-life battery identification by 40%, and adoption among second-life operators rose to 24.3% from 8% in 2023.
- Direct recycling can reduce processing costs by 30-40% versus conventional hydrometallurgical methods by preserving cathode materials; technologies from Ascend Elements and Princeton NuEnergy are scaling commercially in 2025-2026, with a VW-Ascend Elements joint venture providing OEM validation.
- Redwood Materials raised a $425 million Series E in January 2026 and partnered with Rivian on a 10 MWh storage project in 2025, positioning the company as a leading scaled circular materials platform in the EV battery recycling value chain.
- Used EV batteries typically retain around 70-80% of original capacity, but heterogeneous chemistries, incomplete history data, and limited long-term field evidence make utilities and financiers cautious about bankrolling large second-life storage portfolios.
- Roughly 185 GWh of batteries are forecast to be available for second-life applications by 2030, representing only a small portion of the total installed EV battery base and constraining near-term scale for reuse-led business models.
FAQ's
The three main barriers are: inconsistent state-of-health data forcing costly physical testing, falling new battery prices compressing second-life economics, and battery chemistry fragmentation (LFP alongside NMC) requiring different testing and repurposing approaches, raising facility complexity and capital requirements.
