Thereafter, on a global scale, set off a craze of the theory with solid polymer electrolyte materials research and technology development, a lot of research work has been in the field to start and made ​​great achievements in the preparation and study of different substrate materials composite polymer electrolytes, the most promising as lithium solid electrolyte materials.
With the increased population growth, environmental pollution and energy critical global issues, development and application of renewable and environmentally friendly new energy materials has become the field of materials science in a very important and active side, and caused great concern of the world and attention.
So far, it has a large number of high conductivity of solid materials to replace the liquid electrolyte.
The composite polymer electrolyte materials has become an intersection of many disciplines including materials science, chemistry, physics, and the content may lead to the field of new energy materials, in particular, is a new technological revolution in the field of battery materials, which study of the problem will continue and in-depth.
