Final answer:
It is true that a lithium battery label can be placed over the edge of a box to partially cover two sides for visibility and safety reasons. These labeling requirements come from international shipping regulations for the transportation of potentially hazardous materials, like lithium batteries.
Step-by-step explanation:
The statement that a lithium battery label can be placed over the edge of the box so that it partially covers two sides is generally considered to be true. This practice is often required for safety and regulatory compliance when shipping lithium batteries, as it ensures that the label is visible from multiple angles. This requirement is aligned with guidelines provided by international regulations for the safe transportation of dangerous goods, including lithium batteries, which can pose a fire risk if damaged or improperly handled.
However, the rules can vary depending on the shipping company and the specific regulations that apply to the type of lithium battery being shipped. The label must include the positive electrode and negative electrode indications, the battery type, and other relevant warnings and information. Shippers should always consult the latest guidelines from regulatory agencies and carriers to ensure compliance.
It's important to note that the concept of positive and negative electrodes is centered around the principle of charge movement within the battery, where lithium ions are transferred between the anode and cathode, as opposed to electrons or protons directly leaving or entering the battery.
