At present, the energy density of the mainstream lithium iron phosphate battery and ternary lithium battery is between 200 and 300 Wh kg −1 or even <200 Wh kg −1, which can hardly meet the continuous requirements of electronic products and large mobile electrical equipment for small size, light weight and large capacity of the battery …
Five years later, Akira Yoshino of Meijo University in Nagoya, Japan uses a carbon material as a negative electrode instead of lithium metal. This led to a revolutionary discovery: not only was the new battery significantly safer without lithium metal, but the battery''s performance was more stable, producing the prototype of the LIB.

How does a lithium-Ion battery work?
When the electrolyte is based on a mixed solvent, such as the typical formulation of a commercial lithium-ion battery, and regardless of whether it is a negative electrode or a positive electrode, the preferential coordination of EC increases its chance of participating in the formation of SEI and CEI compared to DMC or other linear carbonates.
