Comparing to other rechargeable batteries, Li-ion battery could reach the highest energy density today. Many scientists still keep researching to achieve higher energy density of Li-ion batteries. So what exactly limits the batteries’ energy density? It seems there are many factors affecting it, such as, the materials of positive electrode and negative electrode, the electrolyte, and the diaphragm... Some people think improving Li-ion batteries’ energy density may involve many things. It won’t be so simple with only changing the materials, because the balance of internal material composition even if a little wrong can cause serious problems. The real breakthrough in battery technology seems to be very difficult. When will the next breakthrough comes out in the battery industry? Welcome to share your kind comments.
