The market for lithium-ion batteries is growing in line with the rising demand for laptops, smartphones and tablets. It is anticipated that the market will expand further, mainly in China, given that plug-in hybrid vehicles and electric vehicles (EVs) with smaller environmental footprints will come into widespread use.

In collaboration with Formosa Plastics, Mitsui Chemicals constructed the facilities to produce high quality electrolyte solution, beginning commercial operation in July 2016. In preparation for the market growth, the recent expansion was made to bolster the supply system by calling on well established technologies and knowledge on electrolyte solution, to meet growing demand in the Chinese market.
