How does the structural design of a battery affect its flexibility?

The structural design of the battery significantly influences its flexibility. Variations in the structural designs of the batte-ries result in them experiencing different forces during deformation, including the location of the force and the direction and magnitude of the stress. To further Figure 3.

What happens after a battery module is assembled?

After the battery module is assembled, it needs to be placed into the battery tray. As this tray is a key structural component of the vehicle as well as integral in protecting the battery cells, it needs to be of the highest strength and stability.

Do flexible batteries need structural design?

However, the development of flexible bat-teries is largely focused on advanced electrodes or electrolytes, and little attention is paid to the structural design. In this perspective, we highlight the structural design strategies and corresponding requirements of flexible batteries for typical flexible electronic de-vices.

Are flexible batteries based on structure classification?

Although flexible batteries have come a long way, most of them focus on the exploitation of advanced materials and the enumeration of potential structures. The prevailing approach to structure classification in the field is still based on the shape and mode of deformation of batter.

How can a battery be flexible?

The flexibility of batteries can be achieved by flexible substrates such as flexible foil or wire in the deformed region. Similar to PAMAD, the thickness of the deformation area is much thinner than the active material area to keep the balance between high energy density and flexibility.

How does a battery tray assembly work?

The battery tray assembly consists of several production steps. Depending on the battery design and manufacturing processes, manual tightening with bolt positioning and process control, or flow drill fastening with K-Flow technology can bring the needed process quality, productivity and flexibility.
