Use of High-Pressure Homogenization in Lithium Batteries


Lithium, used in high-pressure homogenization for lithium batteries, possesses a high redox potential. It is also electrochemically active. These attributes make it highly suitable for modern electric vehicles. Primary lithium-ion batteries power electronic devices, telephones, while secondary lithium-ion batteries are used in laptops and mobile phones. Batteries consume 39% of lithium. The demand for lithium is high, particularly for use in video cameras, computers, mobile phones, and rechargeable devices. Lithium-ion batteries will continue to be necessary for hybrid vehicles that provide power balance in electrical production systems with solar and wind energy.

What is a Lithium Battery?

A Lithium-ion (Li-on) battery is a type of rechargeable battery. Lithium is the lightest metallic element and has a low redox potential ( 𝐸𝐿𝑖+⁄𝐿𝑖 0 = −3.04V ), allowing for high voltage and high energy density. Lithium batteries are longer-lasting, have higher power density, charge faster to a certain extent, and are lighter batteries compared to traditional ones. Sodium-based compounds appear to be an alternative for large-scale energy collection systems connected to renewable energy sources.

Why are Lithium Batteries Preferred?

  • They provide high energy, gravimetric energy density (Approximately 202 Wh/kg; volumetric energy density about 300 Wh/dm3).
  • They provide a high average operating voltage (3.6 V).
  • They possess excellent charge-discharge properties, allowing for more than 500 cycles.
  • They have an acceptably low self-discharge rate when idle (<% 10/month).
  • They lack the memory effect found in Ni-Cd batteries.
  • The remaining capacity can be easily identified by examining the battery's discharge curve.
  • They are safer than equivalent cells using lithium metal, requiring no special transportation arrangements.

Usage of High-Pressure Homogenization in Lithium Batteries

Lithium is naturally found mostly in aquatic and terrestrial habitats. However, it is not present in very high concentrations.

Lithium is found in ionic form in water. It reacts with water to form lithium hydroxide and hydrogen. Lithium ions move from one electrode to another according to the battery’s charge and discharge properties.

We use high-pressure homogenization to dissolve molecules above 100 microns, such as sulfur, carbon black, and graphene oxide, in water. The pressure value typically used ranges between 800 and 1200 bar.
