Ni MH battery is composed of hydrogen ion and metal nickel. Its power reserve is 30% more than that of Ni Cd battery, lighter than Ni Cd battery, longer service life and no pollution to the environment.
Chemical composition: the "metal" part of Ni MH battery is actually metal hydride. Used in the manufacture of Ni MH batteries, they are mainly divided into two categories. The most common is AB5, a is a mixture of rare earth elements (or) plus titanium (T); B is nickel (Ni), cobalt (CO) Manganese (MN), (or) and aluminum (AI). The "multi-component" electrodes of some high-capacity batteries are mainly composed of AB2, where a is titanium (TI) or vanadium (m, B is zirconium (Zr) or nickel (Ni), plus some chromium (CR) and cobalt (CO) Iron (FE) and / or manganese (MN). All these compounds play the same role: reversibly forming metal hydrides. When the battery is charged, the hydrogen ion (H +) in the potassium hydroxide (KOH) electrolyte will be released and absorbed by these compounds to avoid the formation of hydrogen (H2) to maintain the pressure and volume inside the battery. When the battery is discharged, these hydrogen ions will return to their original place through the opposite process.
1. Enterprises should pay attention to matters related to the transportation of dangerous goods of Ni MH batteries and carefully study the classification items of Ni MH batteries in the new rules;
2. Strengthen the contact with the inspection and quarantine department and the maritime department, timely understand the relevant rules for the transportation of dangerous goods, adopt the packaging and transportation methods of dangerous goods, and make every effort to meet the requirements Meet the transportation conditions required by the new rules;
3. Take timely countermeasures to avoid the loss of goods detention or return due to illegal packaging and transportation, and ensure the smooth export of Ni MH batteries.
4. Because battery products are easy to cause personal injury, property damage, environmental injury and damage during transportation, loading and unloading, storage and other processes, special precautions are needed Protection shall be packaged, stowed, isolated and consigned in accordance with the corresponding dangerous goods transportation items in the international maritime dangerous goods code.
