There is no such thing as "plain Lithium-Ion". Lithium-Ion is a catch-all term for accumulator cells which use Lithium ions in anode, cathode and electrolyte. There are many versions of them. The oldest type is Lithium-Cobaltoxide (LiCoO2), which uses Cobalt(II)-oxide in the cathode. Then there is Lithium-Nickel-Maganese-Cobalt (LiNMC), which is often used in cars, because it allows for very dense accumulator cells. Lithium-Ironphosphate (LiFePO4), while having the same gravimetric density as LiNMC, takes up more space for the same capacity, it is a more fluffy material. We have Lithium-Nickel-Cobalt-Aluminium-Oxide (LiNCA), used in the cells Panasonic builds for Tesla. Many pedelec batteries, but also the Nissan Leaf use Lithium-Manganeseoxide (LiMO) cells.
