Strip grinding lithium battery

Can lithium metal be used instead of graphite?

Li-metal is known as a high energy density material with ideal theoretical capacity (3860 mAh g −1) and low redox potential (−3.04 V vs SHE) . Hence, such properties made lithium metal a promising anode material to be used instead of graphite.

What is a wet grinding system?

Wet grinding system is solution for Anode materials. Nowadays due to many requirements especially for larger capacity, silicon based anode material has been highly regarded as a next generation anode material. Because silicon has around 10 times higher theoretical specific capacity compare to graphite.

Why do we need a wet grinding system for anode materials?

For this reason, a narrower particle size distribution is required, and grinding solutions such as Neos, Zeta can meet the required particle size distribution. Wet grinding system is solution for Anode materials.

Can electrodeposited Zn coatings improve the lithium plating-stripping process?

In this work, we propose electrodeposited Zn coatings at different coating thickness on Cu current collector as suitable and easy approach to improve the lithium plating-stripping process. The zinc plated anode design promoted a smooth, dendrite-free lithium deposition, attributed to favorable lithium alloying on the lithophilic Zn-coated surface.

What is anode-free lithium battery (AFLB)?

Due to the aforementioned challenges, the new concept of anode-free lithium battery (AFLB) has emerged. In this regard, an anode-free battery includes zero excess lithium on the anode and the copper current collector is directly in contact with the membrane (separator) in the absence of lithium foil.

What happens if a lithium anode reacts with an electrolyte?

Nonetheless, such a high amount of excess lithium as anode active material can react with the electrolyte and can lead to rapid consumption of electrolyte and growth of Li nucleation sites which results in the dendritic growth of lithium.
