In recent years, the world has been highly concerned about environmental issues, including the European Union, the United States and China have set a clear goal of "carbon neutrality". In view of this, the transportation industry, which accounts for 16% of global carbon emissions, in order to achieve the high standard of net-zero emissions in 2050, the key way is to replace the existing fuel vehicles with electric vehicles; such a big change not only brings new challenges to the market, but also brings catalysts for growth for the core technology manufacturers of electric vehicles. Among them, the battery module market, which accounts for 40~50% of the total vehicle cost, not only has huge potential, but also the existing solutions still have different shortcomings, and the market has yet to make a choice as to whether the battery type tends to become zero or not.
