According to the development history of the auto industry, all-electric cars full beyond or replace the critical point of internal combustion engine car, mainly depends on the battery energy density and the cost of lithium-ion battery, when reached to these two points, pure electric vehicles can be almost twice as many car fuel efficiency, supplemented by more efficient electric power system. This is also one of the reasons why the industries desire to see the future development of new energy vehicles and the relevant heat sink manufacturing capability, especially aluminum heat sink manufacturing.

The expert analysis of liquid cooling heat sink said that how fast the pure electric car can surpass the internal combustion engine car can not be calculated very accurately. In the past few years, we could tell that lithium battery cost are falling at an annual rate of 7%. It is estimated that the cost of lithium batteries is expected to be close to 1 yuan/Wh in 2020 or 2021.
