State-of-Health (SoH) measures a battery’s remaining usable energy compared to when new, and although the EU regulation uses the standardized State of Certified Energy (SoCE), in practice SoH effectively reflects the same concept of energy-related degradation.

The carbon footprint of Li-ion batteries, largely driven by energy-intensive raw material extraction and assembly, can vary from 77 to 221 kg CO₂e/kWh, making it essential to extend their lifespan and promote circular economy practices like repair, reuse, and recycling.

Batteries store energy through chemical reactions in cells, whose arrangement and management by a BMS ensure safe, balanced charging, optimal performance, and prolonged lifespan.

Bib batteries partnered with WeRECY to give a second life to end-of-life Voi scooter batteries, extending their use in less demanding applications like public lighting while reducing costs and environmental impact.

Bib batteries helped VelyVelo diagnose, sort, and repair 200 malfunctioning e-bike batteries, restoring over 80% to service, cutting costs by two-thirds, and significantly reducing environmental impact.

Bib batteries, in collaboration with Dott and Manufacturing Partners, gave a second life to 1,200 e-scooter batteries—now powering an electric boat—avoiding 67 T of CO₂ emissions and demonstrating sustainable battery reuse in the circular economy.

Lithium-ion batteries come in various chemistries—LFP, LCO, NMC, LMO, NCA, and LTO—each balancing trade-offs in energy, power, cost, safety, lifespan, and recyclability to suit different applications and user needs.

Battery production and use consume significant energy and materials, generating CO₂ and societal impacts, but when used efficiently—especially with green electricity—they remain a cleaner alternative to fossil fuels.

Battery degradation, caused by electrode wear, chemical reactions, and external stresses, reduces capacity, increases resistance and heat, and makes usage more costly, inefficient, and potentially unsafe.

Proper management of end-of-life mobility batteries—through diagnosis, repair, second-life reuse, and, as a last resort, recycling—extends their lifespan, reduces costs, and minimizes environmental impact.

Second-life batteries offer a sustainable way to extend battery lifespan, supporting domestic, industrial, and grid applications while reducing costs and environmental impact.

The circular economy extends lithium batteries’ lifespan, reducing waste and environmental impact through collection, repair, reuse, and, as a last resort, recycling.

End-of-life batteries (70–80% SoH) pose fire and pollution risks if landfilled, while recycling is energy-intensive. Reuse is the preferred option, giving still-functional cells a second life.
