As is well known, when consumers choose electric vehicles, the range is one of the important factors. In order to meet the needs of consumers, various car companies constantly find ways to increase the range of cars and improve battery energy density. Therefore, the trend of high nickel content in t...

1. High specific energy type electrolyteThe pursuit of high specific energy is currently the biggest research direction for lithium-ion batteries, especially as mobile devices occupy an increasing proportion in people's lives, battery life has become the most critical performance.2. High power e...

Capacity is one of the most important parameters of lithium-ion batteries, and its size varies with temperature.After expert analysis, the temperature limit set for mobile lithium-ion batteries is generally between 40-60 degrees Celsius, and explosion-proof valves are usually marked on the batteries...

Reasons for ignition of power lithium-ion battery packsThe essence of causing a lithium-ion battery pack to catch fire is that the heat inside the battery is not released according to the design intention, causing the ignition point of internal and external combustibles to ignite. The main causes of...

Cylindrical lithium-ion batteries are divided into three different systems: lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, cobalt manganese mixture, and ternary materials. The outer shell is divided into two types: steel shell and polymer. Different material systems have diff...

At present, most of the lithium batteries for forklifts in China are only soft pack batteries, using aluminum-plastic film as the outer shell, but the electrolyte has not changed. This type of battery can also be thinned, with better low-temperature discharge characteristics than forklift batteries,...

Positive electrode material is one of the key materials that determine the performance of forklift lithium-ion batteries, and it is also an important source of lithium-ion in commercial lithium-ion batteries. Its performance and price have a significant impact on lithium-ion batteries.With the conti...

In nature, lithium is the lightest and least atomic weight metal, with an atomic weight of 6.94g/mol= 0.53g/cm3. Lithium has active chemical properties and is prone to losing electrons and being oxidized to Li+. Therefore, the standard electrode potential is negative, at -3.045V, with the smallest e...

Part or all of the lithium that occurs during the charging of lithiumforklift batteries cannot be inserted into the interlayer structure of the negative electrode graphite, and will precipitate on the surface of the negative electrode, forming protruding dendrites. In the next charging, this p...

Polymer batteries are a new type of lithium-ion battery, characterized by their thinness, light weight, and diverse appearance. Most polymer batteries can also be coated with aluminum-plastic film, ensuring safety during use. However, improper operation may cause temperature rise or oxidation, and t...
