Can lithium iron phosphate reach 208 Mah G1?

Here we report that the carbon-coated lithium iron phosphate, surface-modified with 2 wt% of the electrochemically exfoliated graphene layers, is able to reach 208 mAh g−1 in specific capacity.

Is lithium iron phosphate a good cathode material?

The specific capacity of an important commercial cathode material, lithium iron phosphate, is much lower than its theoretical value. Hu et al. report that incorporation of electrochemically exfoliated graphene layers in a carbon coating improves capacity beyond that predicted by theory.

What is lithium iron phosphate (LFP)?

Lithium iron phosphate (LiFePO 4 or LFP), one of the very popular commercial cathode materials for Li battery, exhibits several advantageous features for the energy storage such as low cost, environmental capability, relatively large capacity and intrinsic stability.

What is the specific capacity of cathode Carbon-coated lithium iron phosphate?

Nature Communications 4, Article number: 1687 (2013) Cite this article The specific capacity of commercially available cathode carbon-coated lithium iron phosphate is typically 120–160 mAh g −1, which is lower than the theoretical value 170 mAh g −1.

Why do graphene flakes have a high mAh capacity?

The excess capacity is attributed to the reversible reduction–oxidation reaction between the lithium ions of the electrolyte and the exfoliated graphene flakes, where the graphene flakes exhibit a capacity higher than 2,000 mAh g −1.
