The new Lithium Titanate technology
Lithium based technology: Lithium titanate (Li4Ti5O12, referred to as LTO in the battery industry) is a promising technology for applications with high requirements like high charge and/or discharge current rate, long life time and extreme temperature conditions.
Safety, stability: LTO offers advantages in terms of power and chemical stability. The LTO based batteries have lower voltage: between 2.8V and 1.5V (the nominal voltage is 2.3V). Nevertheless, the lower operating voltage brings significant advantages in terms of safety.
Fast charge and discharge: Further, these batteries can be charged fast. Data shows that these batteries can be safely charged at rates higher than 5C. This means the battery can be charged in less than 10 minutes. The maximum charge and discharge rate is 10C so in this case it is 400A!
High efficiency: The LTO based batteries also have a wider operating temperature range and a recharge efficiency exceeding 98%.
Wide operation temperature rage: LTO based batteries provide much better low temperature performance compared to carbon based batteries. The operation ambient temperature range is from -50°C to 65°C.
Extreme durable life-cycle: The large cycle life and high rate capability of LTO based batteries also brings unique advantages in applications where maximal cycle life is required. Using those cells propery you can easily exceed 30,000 cycles life-time.
