Performance comparison of lithium titanate batteries

LTO Advantages

LTO material has higher electric potential with lithium metal,avoiding lithium dendrite during the process of battery overcharging,and has better safety and stability.Meanwhile,it has three-dimensional lithium-ion transmission channel,which can charge and discharge at high rate;full charging and sicharging from extremely low temperature-50°C to ultra-high temperature 60°C can be realized.

High Security

Results show that:The LTO titanium batteries don’t occur fire or explosion after penetration,electric drill,cutting and other tests.

Remark:This is a professional test.Never imitate !
