Lithium 32700 12V 100Ah EWT Scooter Camping Golf Battery 50A

Scientists have increased the capacity of their batteries in many charge and discharge cycles through a promising high-rate electrode material with a unique flower-shaped nanostructure.

Lithium-ion batteries work by scrambling lithium ions between the positive (cathode) and negative (anode) during charging and shuttling in opposite directions during discharge. Our smartphones, laptops, and electric vehicles often use lithium-ion batteries with a negative electrode made of graphite, a type of carbon. When charging the battery, the lithium is inserted into the graphite and removed when the battery is in use.

Although graphite can be reversibly charged and discharged over hundreds or even thousands of cycles, the lithium capacity it can store is not sufficient for energy-intensive applications. For example, an electric car can only travel that far and needs to be recharged. In addition, graphite cannot be charged or discharged at very high rates (power). Because of these limitations, scientists have been looking for alternative anode materials.

One promising anode material is lithium titanate (LTO), which contains lithium, titanium, and oxygen. In addition to its high-rate performance, LTO has good cycling stability and maintains vacancies within its structure to accommodate lithium ions. However, LTO has poor conductivity and the diffusion of lithium ions into the material is slow.
