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

There are two basic processes of internal short circuit of battery caused by metal foreign matters, as shown in Figure 1. In the first case, large metal particles directly pierce the diaphragm, causing a short circuit between the positive and negative electrodes, which is a physical short circuit.

An international team of scientists focusing on next-generation energy storage solutions recently demonstrated an environmentally friendly and low-cost battery with exciting potential. Compared with typical lithium-ion batteries, this new sodium sulfur battery design provides four times the energy capacity, which is a promising technology for energy storage in the future grid scale.

The battery module can be understood as the intermediate product of the battery cell and pack formed after the lithium ion battery cells are combined in series and parallel, and the single battery monitoring and management device is installed. Among the three common lithium battery packaging forms, the single energy density of the soft package lithium battery is the most easy to achieve, but when it comes to module design, the task of considering the overall safety of the product is the most important, which can be said to transfer part of the cell activity to the module structure.
