The long-awaited partnership between Nio and fossil fuel energy giant China Petrochemical Corp (Sinopec) has finally been confirmed.

The electric vehicle company sent out a media invitation Tuesday saying it will sign a strategic cooperation agreement with Sinopec on April 15, and that its first second-generation battery swap station will go live at a Sinopec station in Beijing on the same day.

"You are invited to witness an important milestone in Nio's development," the invitation reads. Nio will build battery swap stations at more Sinopec stations, Chinese media reports said.
