Cause analysis of battery shell and explosion

Cause analysis of battery shell and explosion

Lithium is the smallest and most active metal on the periodic table. Due to its small size and high capacity density, it is widely welcomed by consumers and engineers. However, the chemical properties are too active, which brings a very high risk. When lithium metal is exposed to air, it will explode due to a violent oxidation reaction with oxygen. In order to improve safety and voltage, scientists have invented materials such as graphite and lithium cobalt oxide to store lithium atoms. The molecular structures of these materials form tiny storage lattices at the nanometer level, which can be used to store lithium atoms. In this way, even if the battery casing is broken and oxygen enters, the oxygen molecules are too large to enter these tiny storage cells, so that the lithium atoms will not come into contact with oxygen to avoid explosion. This principle of lithium-ion batteries enables people to achieve the purpose of safety while obtaining its high capacity density.

Reasons for the decline of lithium battery

Reasons for the decline of lithium battery

According to the research survey, due to the high energy storage density, materials such as metal oxides, sulfides and fluorides are promising electrode materials for lithium-ion batteries for electric vehicles. However, their energy storage capacity decays quickly. A few days ago, scientists discovered by studying a lithium-ion battery with an iron oxide electrode that the loss of the battery after charging and discharging more than 100 times is caused by the accumulation of lithium oxide and the decomposition of the electrolyte.

Several factors affecting the performance of lithium battery

Several factors affecting the performance of lithium battery

The size of the discharge current affects the lithium battery. Different lithium batteries support different discharge rates. Usually, there are batteries with discharge rates of 0.2C, 0.5C 1C 3C 5C 10C 20C, and the same type of battery. Under different discharge rates, the capacity retention rate is different. The larger the discharge rate, the less capacity will be released. Therefore, when choosing a lithium battery, pay attention to choosing a battery suitable for the load working current. Of course, a battery with a larger discharge rate will have a smaller nominal capacity and a relatively lower energy density. The better the current flow through the internal tabs and welding positions, the smaller the internal resistance of the battery. For the same type of battery, long-term high-rate discharge will also affect the cycle life, and the cycle life will decay faster.

Comparison of characteristics and parameters of six common lithium batteries

Comparison of characteristics and parameters of six common lithium batteries

We often talk about ternary lithium batteries or iron-lithium batteries, which are named after the positive electrode active material. This article summarizes six common lithium battery types and their main performance parameters. As we all know, the specific parameters of batteries with the same technical route are not exactly the same. What this article shows is the general level of the current parameters. The six lithium batteries include: lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), lithium nickel cobalt manganese oxide (LiNiMnCoO2 or NMC), lithium nickel cobalt aluminate (LiNiCoAlO2 or NCA), lithium iron phosphate (LiFePO4) , lithium titanate
