LiFePO4 Battery

Yes, Anker SOLIX C300 uses lithium-iron-phosphate batteries (LiFePO4), a sub-type of lithium-ion batteries.

Note: Lithium-iron-phosphate (LiFePO4) batteries use lithium-iron-phosphate as the cathode material, placing them under the broader category of lithium-ion batteries.

Li-ion 32

"Li-ion 32" on the bottom of the power station is a Japanese recycling symbol.

Here's what each section means in more detail:

 "Li-ion" indicates this product contains a lithium-ion battery.

• The first digit "3" signifies the primary metal content in the active cathode is iron.
• The second digit "2" indicates the battery contains more than 0.5% phosphorus by weight.

This marking is required for compliance with Japan's "Law for the Promotion of Effective Utilization of Resources." It mandates the display of the three-arrow mark recycling symbol and the term Li-ion.

The additional digits are recommended by the Japan Battery Recycling Center to provide information about the battery's composition to aid in recycling efforts. These digits do not require certification, but must be verified by battery manufacturers.

The first digit represents the primary metal content in the cathode active material:

• 0: Cobalt
• 1: Manganese
• 2: Nickel
• 3: Iron

The second digit represents metals that hinder recycling:

• 0: None
• 1: The battery contains more than 1% tin by weight.
• 2: The battery contains more than 0.5% phosphorus by weight.
