Description

technical field [0001] The invention relates to the technical field of lithium-ion battery packaging materials, in particular to a high-performance packaging material for mobile phone lithium-ion batteries and a preparation method thereof. Background technique [0002] Mobile phone battery is an energy storage tool that provides power for mobile phones. It consists of three parts: battery cell, protection circuit and shell. Mobile phone batteries generally use lithium batteries and nickel-metal hydride batteries. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Lithium-ion batteries are used in mobile phones and laptop computers. People usually call them lithium-ion batteries. Batteries generally use lithium-containing materials as electrodes, which are representatives of modern high-performance batteries. Real lithium batteries are very dangerous due to their high risk It is rarely used in daily electronic products. Lithium-ion batteries...
