electric folding bikes prominent characteristics of lithium-ion batteries

Lithium -ion batteries have the following main characteristics:
1.Voltage of a single cell work . Up to 3.7V, nickel cadmium batteries, nickel-metal hydride battery three times , nearly twice the lead-acid batteries . When the composition of the same voltage battery pack , the number of used lithium batteries in series will be considerably less than lead-acid batteries and nickel-metal hydride battery quantity . From this perspective , the Electric Folding Bikes lithium battery is more suitable for use .
2 , light weight , high energy density ( up to 150Wh/kg), 2 times of the nickel hydrogen battery , lead acid batteries 4 times the weight of lead-acid battery is the same energy of 1/ 3 to 1 / 4 .First, relatively few resources consumed lithium , and lithium manganese oxide and lithium iron phosphate reserves in the more elemental , so the cost of lithium batteries will be further reduced.
      Secondly , the weight of folding electric bikes lead-acid batteries for the 12kg-20kg, with a lithium-ion battery electric bike weighs about 4kg, so low on the frame strength requirements , magnesium alloy, aluminum alloy frame applications possible. Also, because the cars are generally simple models of lithium electric bike , to reduce total vehicle weight of at least 20 %. In the case where the same voltage , same capacity battery , more than 10% longer mileage .
      Once again, ordinary folding electric trikes weighing 40kg or more, while the lithium battery electric bikes weigh between 7kg-26kg, in line with national standards of electric bicycles , in line with the direction of the industry. And as to enhance the level of consumption , the absolute increase in people's income , if lithium prices remain largely unchanged, people's consumption concept will be upgraded , domestic lithium car market will soon hot. In addition, with the enhancement of people's concept of environmental protection , the development of domestic electric bicycle quickly developed basically to the current lithium car direction.
3, small size ( up to 400Wh / L), a lead-acid battery 1/ 2 to 1 / 3 . Li-ion battery provides a more rational structure and a more aesthetically pleasing appearance design conditions . Lead acid batteries due to the limitations stage size, weight , designers design is greatly constrained , resulting in a similar stage of the electric bicycle structure and appearance . The lithium -ion battery , giving designers to provide more space and Conditions showcase design ideas and style .
