LG Energy Solution supplied batteries for Apple's wireless earphone 'AirPods'. The bean sprout-shaped AirPods are equipped with a small round stick-shaped battery.

However, the design trend of wireless earphone market has changed, as wireless earphone manufacturers started making earphones in a circular shape by getting rid of the rod shape. Apple AirPods Pro and Samsung Galaxy Buds are the major round wireless earphones. As the product design changed, the battery also changed, increasing the demand for coin-shaped coin cell batteries instead of thin and long batteries.
LG Energy Solutions has been supplying batteries for Apple AirPods since 2016, but the supply is known to have stopped since this year. Apple increased the supply of coin cell batteries with the success of the AirPods Pro, but it is reported that LG Energy Solution missed the time. The company then spurred the development of coin cell batteries and has even succeeded in supplying it to Samsung Electronics.
