The origin of lithium-ion battery The first piece of lithium-ion battery in the world was invented in the United States in March of 1973 An oil company engineer used lithium metal as anode and titanium sulfide as cathode.

How can we identify a lithium-ion battery fire? One of the dangers of a fire for lithium-ion battery is that we cannot judge whether the fire is put out or not visually If it is not completely extinguished, fire will restrike.

Recently, the institute of China chemical and physical power industry announced the 2013 sales revenue ranking of main enterprises in industry of lithium-ion battery It was shown that among the main enterprises of the battery PACK, Desai battery (000049.

First, lithium battery 1 Briefly describe the lithium battery and how it works.

If the battery is likened to the heart of the human body, the module and the battery pack are like a strong body, then the entire power battery system needs to run smoothly, and a brain that governs the body is needed, that is BMS The Battery Management System (BMS) is an important link between battery and electric vehicles.

The process of assembling lithium battery cells into groups is called PACK, and it can be a single battery or a series or parallel battery module Under the background of the new national standard, the demand for lithium batteries is increasing, and many lead-acid battery companies have also introduced lithium-ion products.

It is a very boring technology popular science article We also thought about whether you would be interested in these technical details.

Electrode is lithium ion polymer battery product of a raw material The electrode is divided into three kinds of materials, the battery of the anode materials used aluminum (Al), the cathode materials used nickel (Ni), and the cathode has copper plating nickel (Ni, Cu) materials.

On March 22, 2017, Tesla senior executive KurtKelty had a speech of "Tesla's battery factory materials procurement and production” in international battery seminar It has been a mystery on 2170 Tesla - Panasonic battery monomer cost and energy density asymmetry.

The lithium battery production process:The first step - the preparation of electrode coatingMainly mix up the electrode active material, binder and solvent It will form into a paste after fully mixing dispersion.
