Typical symptoms: Lithium batteries catch fire and produce toxic gases, and the low recycling rate leads to pollution.

Are lithium batteries really "green energy"?

The truth:

Environmental friendliness: They do not contain heavy metals such as lead and mercury, but the lithium hexafluorophosphate in the electrolyte is toxic.

Safety: Punctures, short circuits, and overcharging may cause thermal runaway (such as the explosion incident of Samsung Note7).

Recycling rate: The global recycling rate of lithium batteries in 2023 was only 50%, but technology is advancing (for example, Greengold's low-temperature crushing technology has a recycling rate of 99.2%).

Test case: Laboratory data shows that in the needle-puncture test of 18650 batteries, the liquid electrolyte battery may catch fire, while the solid battery only smokes.

Solution:

Avoid disassembling batteries privately and hand them over to professional recycling institutions.

Choose certified battery products.
