Nio and CATL Collaborate to Develop Long-Lasting EV Batteries

The Issue of Mismatched Lifespans

Just like a pack of hot dogs with more wieners than buns, electric vehicle (EV) batteries often outlast the vehicles they power. By 2025-2030, around 20 million EV battery packs will be out of warranty, leading to potential early retirements for these vehicles due to the high cost of replacements.

Extending Battery Lifespans

Nio and CATL are working together to address this issue by aiming to create batteries that can last up to 15 years, nearly double the current average warranty period of 8 years. Nio has already made progress in developing packs that retain 80% capacity after 12 years and has obtained over 100 patents in battery technology.

Technological Innovations

CATL has also developed technologies such as self-repairing Solid Electrolyte Interphase film and lithium supplementation to enhance battery longevity. By combining their efforts, the companies hope to establish a long-term partnership that benefits both parties.

Implications for Nio’s Business Model

For Nio, longer-lasting batteries could be crucial for the success of its battery-swap station business model. These stations replace depleted batteries with fully charged ones, reducing downtime for EVs and easing strain on the electrical grid. With 2,382 swapping stations in operation, Nio aims to make these facilities profitable with the help of extended battery lifespans.
