Graphite:
Good Electrical Conductivity: Graphite anodes are widely used because of their excellent electrical conductivity. This allows for efficient transfer of electrons during the charge - discharge process. In a Lipo battery, it helps in maintaining a relatively high rate of charge and discharge.
Stable Structure: It provides a stable structure that can withstand the repeated insertion and extraction of lithium ions during cycling. This stability contributes to the overall cycle life of the battery. However, during high - rate charging or discharging, there can be some limitations such as the formation of lithium plating, which can affect the battery's performance and safety.
Lithium - Titanium Oxide (LTO):
Fast Charging Capability: LTO anodes enable very fast charging of Lipo batteries. They can accept a high rate of lithium - ion insertion, allowing for rapid charging times. For example, in some electric vehicle applications, LTO - based Lipo batteries can be charged to a significant level in a matter of minutes.
Enhanced Safety during High - Rate Charging: They are also safer during high - rate charging as the risk of lithium plating and overheating is reduced. This safety aspect is crucial in applications where quick charging is a necessity.
Lower Energy Density: The main drawback of LTO anodes is their lower energy density. So, for a given volume, the battery may not store as much energy as those with graphite anodes, which can limit the range of applications where long - term energy storage is a priority.
