The manufacturing process for Lithium-iron phosphate (LFP) batteries involves several steps, including electrode preparation, cell assembly, and battery formation. The first step in the manufacturing process involves the preparation of the battery electrodes.
Lithium iron phosphate is at the forefront of research and development in the global battery industry. Its importance is underscored by its dominant role in the production of batteries for electric vehicles (EVs), renewable energy storage systems, and portable electronic devices.
Multiple lithium iron phosphate modules are wired in series and parallel to create a 2800 Ah 52 V battery module. Total battery capacity is 145.6 kWh. Note the large, solid tinned copper busbar connecting the modules together. This busbar is rated for 700 amps DC to accommodate the high currents generated in this 48 volt DC system.
The production of lithium iron phosphate relies on critical raw materials, including lithium, iron, and phosphate. While iron and phosphate are relatively abundant, the sourcing of lithium has become a bottleneck due to the increasing demand from various industries.
The first step in the manufacturing process involves the preparation of the battery electrodes. This process includes the mixing of lithium-iron phosphate powder with conductive additives and binders to form a slurry. The slurry is then coated onto aluminum foil for the cathode and copper foil for the anode.
Despite its numerous advantages, lithium iron phosphate faces challenges that need to be addressed for wider adoption: Energy Density: LFP batteries have a lower energy density compared to NCM or NCA batteries, which limits their use in applications requiring high energy storage in a compact form.
