What is a lithium-ion battery?

The growing trend in shifting the utilization of fossil fuel recourses to renewable energy resource drives the development of efficient energy conversion and effective energy storage. Storage materials and devices are therefore highly demanded than ever.

Among the diverse energy storage devices, a lithium-ion battery (LIB), also known as Li-ion batteries, is a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.* LIBs are commonly used in portable electronics such as in PDAs, cell phones, laptops; and also used for electric vehicles and several other applications.

The 2019 Nobel prize in chemistry is rewarded to the development of the lithium-ion battery.

The AkuPure
TM CMC optimizes the performance of aqueous binder systems in lithium-ion batteries:

  • Excellent adhesion, typically in combination with Styrene Butadiene Rubber (SBR), providing high coating quality
  • Low levels of insolubles and ultra high purity (>99.5)
  • Superb slurry stability and dispersion of graphite
  • Excellent battery properties, such as high temperature storage stability and capacity retention (tested on 18650 NMC-type lithium-ion battery)
  • Viscosity levels suitable for a range of anode recipes
