The Ministry of Industry and Information Technology of the People's Republic of China has revised the Regulatory Conditions for the Lithium Ion Battery Industry and the Interim Measures for the Administration of Regulatory Announcements for the Lithium Ion Battery Industry, forming the Regulatory Conditions for the Lithium Ion Battery Industry (2018 version) and the Interim Measures for the Administration of Regulatory Announcements for the Lithium Ion Battery Industry (2018 version), which will be formally implemented from February 15, 2019. This method greatly strengthens the management of the lithium-ion battery industry, guides the transformation and upgrading of the industry, vigorously cultivates strategic emerging industries, and promotes the healthy development of the lithium-ion battery industry. There is no doubt that the new national standard for electric vehicles has had a significant impact on lead-acid batteries

Diaphragm 135 ℃ automatic shutdown protection, using internationally advanced Celgas2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120 ℃, the membrane holes on both sides of the PE composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135 ℃, the PP membrane hole is closed, the battery is internally open, and the temperature of the battery is no longer increased, ensuring the safety and reliability of the battery.

Is there any special reason for the use of aluminum foil and copper foil for the current collection of positive and negative electrodes? Is there any problem with using it in reverse?

These advantages make Li Polymer batteries show unprecedented application potential and broad prospects in portable electronic devices and many cutting-edge fields.
