The stiffened chassis is one benefit. The biggest one is probably being able to stiffen the chassis while lower weight. To stiffen a chassis with metal structural members (while the battery cells are still ''along for the ride'') is a much heavier way than lessening the amount of metal and using the cells (that again, would be there anyway) to help carry the load.

Structural batteries are hybrid and multifunctional composite materials able to carry load and store electrical energy in the same way as a lithium ion battery. In such a device, carbon fibres are used as the primary load carrying material, due to their excellent strength and stiffness properties, but
Conventional battery packs serve no structural function, thus making electric vehicles much heavier than they need to be. This is why the industry is moving towards structural battery packs. The most efficient way to build a structural battery pack is in the form of a sandwich structure, which consists of two face sheets and a core.
This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.
