Caring for the environment and protecting the earth is the unshirkable responsibility of each of us. How do we turn our environmental philosophy into action? As battery consumers, we should buy and use new green batteries; as battery manufacturers, we should process new green batteries. Only through our joint efforts can we create and protect our beautiful and harmonious natural environment. The new green battery is a high-performance, pollution-free battery that has been put into use or is being developed in recent years. Lithium batteries, nickel-metal hydride batteries, mercury-free alkaline zinc manganese batteries, lithium or lithium ion plastic batteries, fuel power batteries, electrochemical energy storage supercapacitors, etc. are widely used in new green batteries. In addition, currently widely used solar cells (also known as photovoltaic power generation) also belong to this category. In order to ensure the safe and reliable use of lithium batteries, experts have carried out a very strict and thorough battery safety design to meet the battery safety evaluation indicators. (1) When the temperature is 135℃, the diaphragm is automatically closed to protect the Celgard2300PE-PP-PE three-layer composite film. When the battery temperature reaches 120°C, the PE film pores on both sides of the composite film are closed, the internal resistance of the battery increases, and the internal temperature of the battery decreases. When the battery temperature reaches 135°C, the PP film hole is closed, the internal circuit is disconnected, and the battery no longer heats up, ensuring the safety and reliability of the battery. (2) Under the condition of adding electro-hydraulic additives, the battery is charged, the battery voltage is greater than 4.2v, the electro-hydraulic electro-hydraulic additives polymerize with other substances, and the internal resistance of the battery is increased, resulting in a large area of u200bu200binternal open circuit of the battery, and the battery will no longer Heat up. (3) Battery cover composite structure The battery cover adopts a scored explosion-proof structure. When the battery heats up, part of the gas that occurs during the activation of the battery expands, and the internal pressure of the battery increases, and the pressure reaches a certain level. (4) Various environmental damage tests Carry out various abuse tests such as external short circuit, overcharge, acupuncture, plate electric shock, incineration, etc., to investigate the safety performance of the battery. At the same time, mechanical performance tests such as temperature shock, vibration, drop, and impact were carried out on the battery, and the performance of the battery in the actual use environment was investigated.
