With the continuous development of electric vehicles. Charging piles are being built more and more. The speed of charging can be faster and faster. The heat dissipation scheme of the charging pile should be done well, which is extremely critical. It will not only affect the working stability of the charging pile, but also affect the service life of the charging pile.

In the 21st century, electronic products are mainly cooled by aluminum. In the past 15 years, flexible graphite sheets have been increasingly used in various high-end consumer electronic devices due to their light and thin characteristics, replacing aluminum for thermal management. At present, there are two kinds of flexible graphite sheet, natural

Foam metal thermal properties include melting point, specific heat, thermal expansion coefficient, thermal conductivity, thermal diffusion coefficient, thermal radiation and thermal shock resistance, some of which are the same as the base material, while others are closely related to the porosity, hole type and pore diameter of the foam material.

In the fields of new energy vehicles, photovoltaic and energy storage, the thermal management system can ensure that the products operate in a good temperature field. Effective thermal management is the main way to solve the damage of new energy products caused by temperature factors.

There is an academic paper on the LETTER page of the world's earliest international scientific and technological journal ;NATURE;, called “An ultrafast rechargeable aluminium-ion battery”. In the academic paper, Dasen’s pyrolytic graphite sheet was used to make the electrochemical measurements. A Swagelok-type cell (1/2 in
