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.

AkuPureTM CMCs are specifically suited for aqueous binder systems in lithium-ion battery anodes which are used typically in combination with graphite and Styrene Butadiene Rubber (SBR) in anode coating to improve binding strength of active graphite on the copper collector. SBR alone cannot generate sufficient coating rheology and slurry stability for graphite powder. Therefore, applying AkuPureTM CMCs will provide excellent dispersion of graphite particles and homogenous distribution of the binder.
