Extremely Safe: A thermal runaway event is significantly less likely to occur in LTO cells. LTO cells can also be re-operated after an event of an over-discharge, unlike conventional graphite based Li-Ion cells. This feature enables the user to operate the battery cells under extreme environmental and usage conditions.

Advantages of the LTO cells: Anode side of ordinary Li-Ion cells are made up of graphite, the anode side of the LTO cell is composed of Lithium Titanate, which has stronger chemical structure than graphite.

Specially designed for defense & aerospace application

This hybrid type cell has incorporated the advantages of NMC, LFP and LTO cells into one cell. It is extremely safe and reliable battery solution for extremely volatile and dynamic operational conditions. The high power, energy and safety features allow the NANO cells to be flexibly applied in various applications.
