Furthermore, lithium-ion batteries are projected to be increasingly used in applications such as energy storage systems and industrial applications.
  2. The market for lithium-ion batteries used in automobiles is rapidly growing in China, driven by government subsidy policies. Demand for battery materials including electrolytes is also sharply increasing, amid an increasingly competitive market as new manufacturers emerge to the forefront.
  3. Ube Industries and Mitsubishi Chemical have agreed to tie-up for their electrolyte businesses in China under a 50-50 joint venture, in order to supply highly competitive electrolyte to the market. It will enable the two companies to combine their production technologies and mutually use their technology resources including intellectual property, in order to enhance their technologies and cost competitiveness.

2.Future Plans

  1. Ube Industries and Mitsubishi Chemical will apply for approval from government authorities in China and other relevant countries, to comply with competition laws. Upon securing the necessary approvals, the two companies will shift their electrolyte businesses in China to a joint operation in April 2017. They will discuss the details of the operating structure and announce them after reaching a decision.
