6 FAQs about [Lithium battery shell method]
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.
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.
How to choose a battery shell material?
Traditionally, high strength is the priority concern to select battery shell material; however, it is discovered that short-circuit is easier to trigger covered by shell with higher strength. Thus, for battery safety reason, it is not always wise to choose high strength material as shell.
