Lithium-ion (Li-ion) batteries are an advanced battery technology which have four major components: anode, cathode, separator, and electrolyte.

Micromeritics offers whole suite of instrumentation, tailored to accommodate every stage of battery manufacturing process.

Surface Area

  • Increase capacity
  • Facilitates fast charging
  • Improve charge/discharge performance

Surface Area Measurement - Value for Battery Industry

  • Understanding the porosity of the electrode materials is important to guarantee the right ion accessibility and charging speed.
  • BET surface area, pore volume and pore size distribution help to optimize your battery components.

Density

  • Optimize electrode packing density
  • Maximize mass/volume density
  • Minimize irreversible capacity

Density Measurement - Value for Battery Industry

  • High T.A.P. density of precursors is expected to obtain a high volumetric energy density.
  • The true density is a good indicator of purity and composition of the cathode which can be used to improve the overall performance of the battery.
  • Monitoring true density of the electrode material ensures stability of the slurry coating and drying process.

Particle Size

  • Maximize capacity
  • Critical for high energy density
  • Influence coulomb efficiency

Particle Size Measurement - Value for Battery Industry

  • The SediGraph is the only instrument that can precisely report weight percent of particles <0.1μm.
  • Industry leader for rough electrode and other precursor materials.
  • Optimize particle size ratio of cathode and solid electrolyte to maximize the energy density.

Porosity Measurement - Value for Battery Industry

  • Understanding the porosity of the electrode materials is important to guarantee the right ion accessibility and charging speed.
  • BET surface area, pore volume and pore size distribution help to optimize your battery components.

Powder Flow Measurement - Value for Battery Industry

  • Understanding a powder’s Specific Energy, an indicator of inter-particular friction and mechanical interlocking, can help reduce agglomerates in the electrode slurry.
  • Determining and optimizing Permeability, a measure of a powder’s ability to release air, can improve slurry dispersion and cavity filling in wet or dry systems.
