What is the role of battery shell in a lithium ion battery?

Among all cell components, the battery shell plays a key role to provide the mechanical integrity of the lithium-ion battery upon external mechanical loading. In the present study, target battery shells are extracted from commercially available 18,650 NCA (Nickel Cobalt Aluminum Oxide)/graphite cells.

What is the power density of a stretchable lithium ion battery?

However, it should be noted that, because of the utilization of aqueous electrolyte, the average potential was around 1.2 V and the maximum energy density obtained was 30 Wh kg −1, less than the reported stretchable Li-ion batteries with organic electrolyte, even though the delivered maximum power density could be as high as 1260 W kg −1.

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 batteries result in them experiencing different forces during deformation, including the location of the force and the direction and magnitude of the stress.

Which shell material should be used for lithium ion battery?

Considering the fact that LIB is prone to be short-circuited, shell material with lower strength is recommend to select such as material #1 and #2. It is indicated that the high strength materials are not suitable for all batteries, and the selection of the shell material should be matched with the safety of the battery. Table 3.
