What is LTO/Lithium Titanate Battery?
- Lithium titanate battery (LTO) uses lithium titanate as negative electrode material for lithium ion batteries
- Can be combined with lithium manganate, NCM materials or lithium iron phosphate
- Deep cycle with more than 25000 times
- One of the best options for solar energy systems
- Suitable for street lamps, home power walls, solar systems, etc.
- Yinlong 66160 can discharge 10C
Fast Charging Technology
6 mins fast charging

Yinlong technology of fast charging can make the time of charging 6-10 minutes.

Safety Testing
Cutting | Over charge and discharge | Burning

Drilling | Stabbing | Stabbing in water


Technical Advantages
Longer Lifespan (Lifecycles ≥25000 times):
The structure of Lithium titanate is spinel. The lattice parameter increases from 0.836 to 0.837 μM, with volume change of only 0.3%, resulting in excellent cycle stability.
In comparison, graphite materials experience 10% volume change rate during charging/discharging, leading to pulverization and reduced cycle life.
Applications
- Intensive energy storage station
- Home energy storage
- Charging pile
- E-bus/E-car
- Electric tools
- Forklift
