The left side of the lithium iron phosphate battery is an anode composed of an olivine structure material, which is connected to the battery with aluminum foil. On the right is the negative electrode of the battery composed of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil.

The "2016 Third China Lithium Battery Industry Summit and Data Conference for Top 100 Lithium Battery Enterprises", sponsored by the lithium power big data and co organized by the electric big data and starting point research, with the theme of "discovering trends and grasping the future", was grandly held in Sheraton Grand China Shenzhen Hotel. More than 400 CEOs and leaders from various subdivisions of the national lithium battery industry chain attended to jointly explore the development trend of the lithium battery industry and grasp the new trend of the lithium battery industry in the future. Through industry interaction, we will promote better collaboration between upstream and downstream of the industry chain, and bring greater breakthroughs and breakthroughs to China's lithium battery industry chain. At this summit, Zhou, Head of Research and Development of Haisida Power

What are the characteristics of lithium iron phosphate battery? 1. High energy density It is reported that the energy density of the square aluminum shell lithium iron phosphate battery unit produced in mass in 2018 is about 160Wh/kg. In 2019, some excellent battery enterprises can reach the level of about 175-180Wh/kg. Some powerful enterprises can increase the overlapping process and capacity or reach 185Wh/kg.

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.
