Is cell-to-pack(C2P)/structural battery technology massively
First of all, cell-to-pack(CTP) != structural battery. CTP means it eliminates modules which saves weight and space, CTP can be structural battery but are not necessarily structural battery. I think CTP is definitely the way to go. Structural battery is a double edged sword, but EV manufactures will gradually pivot to it, because it offers a

Elon twitter: Model Y structural battery pack is next level
No, you can unbolt the battery pack. The battery pack is a very rigid body thank to to glued cells inside and the two metal clamshells to enclose them. The battery pack is multi point bolted to the chassis and so the chassis is a lot more rigid than normal EV where the battery is only a dead weight. But service can always unbolt the battery
Structural battery pack : r/electricvehicles
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.

4680 Structural Battery Pack explained
It''s pretty clear that a single cell high 120kWh pack does not reach the size capacity limit on the CT floor (which is the pink box around the cells), given that we now know that the battery can also extend under the vault cover in the rear (which is actually a bit further back than the pink box), where the "hump" known as the penthouse also is housed.

5 FAQs about [Structural battery pack Malta]
What is a structural battery pack?
The technology behind electric vehicles is evolving quickly, and one of the most promising innovations is the structural battery pack. Structural battery packs are multifunctional materials that serve both for energy storage and structure. As a result, redundant structural elements can be removed, eliminating weight from other parts of the vehicle.
Who makes structural batteries?
Companies that manufacture structural batteries include automakers like Tesla and GM as well as battery makers like BYD and Contemporary Amperex Technology. Some automakers partner up with battery makers to produce their battery packs. Examples include Volvo and Northvolt as well as BMW and ONE (Our Next Energy).
Why do electric cars use structural batteries?
As a result, redundant structural elements can be removed, eliminating weight from other parts of the vehicle. They are said to offer “massless energy storage” because their effective weight is lower than the total weight of the cells (considering the parts they replace). Structural batteries are changing the way electric cars are assembled.
How are structural batteries changing the way electric cars are assembled?
Structural batteries are changing the way electric cars are assembled. Structural adhesives are replacing screws and welds to “glue” components together using a process called adhesive bonding. This process requires additional surface preparation and creates new challenges for automakers and battery makers.
