|E-bikes may be an important transportation for short distances. With a motor as an auxiliary power unit, the speed can be up to 20km/hr, and the power durability is over 40km. It satisfies urban requirements. Even if the e-bike runs out of power on the way home, the user can still ride it as a normal bike. For recreational purposes, the user can ride easier on steep gradients with the auxiliary power unit. So an e-bike can provide a more joyful ride than a normal bike.|
If 50% of the total lead-acid battery production was used for transportation we would save 110 million tons of gasoline a year. This would result in a reduction of 224 million CO2 emissions, which equals to a forest as large as the area of Italy.
However, lead-acid batteries feature low energy density (30Wh/kg), and low energy transfer efficiency (60%) as well. To drive heavy applications such as BEV takes big power, which means more lead-acid batteries are required. This creates a vicious circle because of more wasted electricity. Due to safety concerns, however, there is no suitable substitute. Now, LiFePO4zM’O batteries feature high safety, high energy density (130Wh/kg) and almost perfect energy transfer efficiency (95%). It is a great substitute for a lead-acid battery. Replacing lead-acid batteries with lithium iron phosphate batteries can reduce 85% of lead usage. The lead reduction can provide power for 323 million electric vehicles, and is equal to the capacity of 40 nuclear power plants.
More importantly, 85% capacity of Dongjian’s LFP battery can be charged in 15 minutes. It means the user doesn’t have to waste a lot of time charging.
