Key Differences Between Lithium-Ion and LFP Batteries

Bigbattery08 Jun, 2026Business

Obviously the main difference between lithium-ion and LFP batteries is in the battery chemistry. The former uses lithium-ion chemistry as a cathode material and the latter uses lithium-iron-phosphate as a cathode material. The nominal voltage per cell of most LiFePO4 batteries is slightly lower than li-ion cells at 3.2 volts compared to somewhere between 3.6 to 3.7 volts per cell for the latter. This means that li-ion batteries have slightly higher energy density.
