Do lithium-ion batteries need warning labels?

Warning labels (or marking) of these batteries are essential to ensure safe handling, operation, and disposal, thereby mitigating potential safety risks and preventing accidents. This paper examines the labeling practices of over 200 lithium-ion cells from 20 manufacturers and 6 countries and reviews changes in warning labeling from 2003 to 2023.

Do batteries require labeling?

Existing labeling requirements in the United States, the EU, and Japan do include messaging and/or symbols indicating that batteries and battery-containing products should be recycled. However, battery labels do not provide clear instructions for users to determine where or how batteries should be collected.

Do batteries have their chemistry on the label?

Consistent across all three EPR laws is the requirement that batteries sold within the state must include the battery chemistry on the label.

Are battery labels safe?

While companies like Hohm Tech and Efest provided safety warnings, usage, and handling instructions on their battery labels, others, such as Panasonic and LG, only focused on fire and explosion risks. Companies, such as Tenergy and Molicel, provided no safety text labeling.

Why do battery labels need to be updated?

Emerging battery chemistries, such as solid-state, lithium‑sulfur, and sodium-ion batteries, necessitate continuous updates to labeling requirements to align with evolving safety, performance, and regulatory considerations. Maintaining accurate and up-to-date labels requires ongoing monitoring and adaptation.

What are the marking requirements for batteries?

As of January 1, 2030, batteries must be marked with proper labeling to ensure proper collection and recycling. This labeling should identify the chemistry of the battery and include an indication that the battery should not be disposed of as household waste.
