The suspension has been a resolve of "resolving production issues", which are mainly attributed to bottlenecks in battery supply, according to Business Insider. Audi uses battery cells that are made by LG Chem and ran into similar battery supply chain issues last year. 

Making sure companies have a steady battery supply has become a priority for many EV makers. Names like Jaguar and Hyundai have also faced similar supply chain issues with batteries in the past. Other automakers, like GM, Toyota and Tesla are investing in joint ventures or building their own battery manufacturing facilities.

As one example, GM and LG Chem announced a deal last year where they would both invest a cumulative $2.3 billion into a battery factory in Ohio.
