LTO CHARACTERISTICS
What does a lithium titanate battery look like?
In the LTO battery, lithium titanate oxide (Li2TiO3) replaces graphite (carbon) in the anode, an element found in classic lithium-ion batteries. The cathode can be lithium manganese oxide (LMO) or lithium manganese cobalt oxide (NMC).
Under the microscope, the LTO reveals a three-dimensional structure consisting of lithium titanate nanocrystals. The cell has a voltage of 2.4 V, can be recharged quickly, and can withstand a discharge current of up to 10 times its rated capacity.
BENEFITS
The advantages of the new lithium titanate battery technology lie mainly in the anode surface area, which is about 100 square meters per gram, compared with only 3 square meters per gram in conventional lithium-ion batteries (3.7V). This greater surface area available for electron passage allows for rapid charging and longer battery life.
This means that less charging power is required and these batteries can be safely recharged in about 6-10 minutes, rather than the 8 hours required for other rechargeable batteries. In addition, the charging efficiency exceeds 98%.
RISKS
The lower operating voltage (2.4V) compared with conventional lithium cells (3.7V) offers advantages in terms of both safety and environmental impact. The absence of carbon in lithium titanate batteries reduces the risk of thermal instability and overheating, which are the main cause of fires in traditional storage systems.
According to tests conducted and verifiable by any LTO manufacturer in the world, an LTO cell subjected to a short circuit reached a maximum temperature of 90-100°C without causing explosions or fires, phenomena to which traditional lithium-polymer batteries can be subjected.
