Problem
Lithium‑ion batteries in electric vehicles and other applications lose capacity over time due to electrolyte breakdown, leading to costly replacements and increased environmental impact. Traditional recharging methods cannot reverse this degradation, and disassembly for refurbishment is labor‑intensive.
Solution
Tiontech offers a patented, non‑invasive recharging technology that restores degraded lithium‑ion cells without dismantling the battery pack. The system applies a bidirectional DC voltage with controlled AC oscillation, reducing oxygen‑derived by‑products and reversing electrolyte decomposition. By converting harmful degradation products back into usable forms, the process revives original battery health and extends the service life of EV packs. The technology can be integrated as an external unit or embedded directly into vehicle battery management systems, enabling on‑site rejuvenation. This approach reduces replacement costs, lowers CO₂ emissions, and improves overall vehicle longevity.
Target Audience
Primary customers are electric vehicle manufacturers, fleet operators, and battery pack integrators seeking to extend battery lifespan and reduce replacement expenses.
