FAQ
Q: Why are lithium batteries cylindrical?
A: Cylindrical cells are small and round, making it possible to
stack them in devices of all sizes. Unlike other battery formats,
their shape prevents swelling, an undesired phenomenon in batteries
where gasses accumulate in the casing.
Q: What is the difference between LiFePO4 prismatic and
cylindrical?
A: “lithium battery cylindrical”. Overall, due to the different
manufacturing processes, the cylindrical type will have slightly
more cycles than the prismatic LiFePO4 cell. Cylindrical cells will
be heavier because most of them have steel shells. Prismatic cells
are lighter because most of them use stainless steel and aluminum
shells.
Q: Are LFP batteries cylindrical?
A: Cylindrical lifepo4 batteries include 18650, 26650, and 32650.
These three markets have more batches and the most common ones.
There are also some less commonly used cylindrical batteries such
as 18500 and 22650. Cylindrical lithium iron phosphate batteries
include 18650, 26650, and 32650.
