LTO Battery(Lithium Titanate Battery) This technology is known for its very fast charging, low internal resistance/high charge and discharge-rate, very high cycle life, and excellent endurance/safety. It has found use mostly in electric vehicles and energy storage and wristwatches.More recently, it is beginning to find use in mobile medical devices due to its high safety. One underlying reason for this technology characteristics is that the chemistry uses nanocrystals on the anode instead of carbon, which provides much more effective surface area. Unfortunately, however, this battery has lower terminal voltages than other Lithium types. · Specific energy: approximately 30-110Wh/kg · Energy density: as high as 177 Wh/L · Specific power: 3,000-5,100 W/kg (peak load) · Discharge efficiency: approximately 85%; charge efficiency over 95% (low-rate) · Energy/consumer-price: 0.5 Wh/dollar · Service or shelf life: >10 years (some to 20 years) · Self-discharge: 2-5 %/month · Cycle durability: 6,000 cycles to 90% capacity (some models >10,000 cycles) · Nominal cell voltage: 1.9 to 2.4V · Cut-off voltage: 1.5V typical (some at 1.7V) · Temperature: -40 to +55°C (extended models) · Charging technique is using standard constant current, followed by constant voltage until the amps threshold is reached.
