It also increases the service life of the batteries. Another advantage of graphite rounding: it improves the intercalation kinetics - and thus the conductivity - of the lithium ions in the battery anode. However, the existing processes for graphite spheroidisation only produce a low yield of about 30 to 50 %.

The round lithium battery refers to the cylindrical lithium battery. Because the history of the 18650 cylindrical lithium battery is quite long, the market penetration rate is very high. The cylindrical lithium battery adopts various mature replacement processes, the degree of automation is high, and the product mass transfer is stable.
After watching some tear-down videos on YouTube with various lithium battery products (portable chargers, laptop battery, power tools) they all (apart from mobile phones / tablet battery) seem to feature cylindrical battery cells.
I'd say the opposite is the case. Nearly all alkaline cells (and zinc carbon etc.) are round. The square-ish packs are made up of round cells ( e.g. 9V; the larger sizes such as lantern batteries often use C or D cells internally). The main exceptions are lead-acid and lithium, such as phone batteries.
The simplest reason there are a lot of round cells is the reason that tek states in his comment. The batteries consist of two electrodes seperated by an electrolyte, one set gives the normal voltage. To increase capacity and current capability, the electrodes and seperator are typically very thin and are wound up into a "jelly roll".
At present, there are three main types of mainstream lithium battery structures, namely, cylindrical, rectangular and pouch cells. Different lithium battery structure means different characteristics, and each has its own advantages and disadvantages. 1. The cylindrical lithium battery structure
I do note that a remarkably large number of batteries, lithium or not, use a cylindrical form factor. The battery (not just lithium ion) consists of two materials separated by a thin semi-permeable membrane soaked in electrolyte. One of the simplest ways to make a high capacity battery not a big sheet is to roll it up.
