Lithium electric bike, gorgeous concise appearance, more and more consumers are accepted, Lithium Battery Electric Bike dynamic performance and lead-acid batteries (simple models electric bike), charge 6 ~ 8 hours, according to the battery capacity can be run 30 ~ 45 km, the weight of only about 1/5 of lead-acid batteries, the biggest advantage of Lithium Battery Electric Bicycle is long life. Lithium resistance overcharge, charge and discharge resistance.

The main uses of bismuth are (1) as a heat shield coating material.镱 can significantly improve the corrosion resistance of the electrodeposited zinc layer, and the ruthenium-containing coating is finer and more uniform than the ruthenium-free coating. (2) Used as a magnetostrictive material. This material has the property of being super magnetostrictive, that is, expanding in a magnetic field. The alloy consists essentially of ytterbium / iron alloy and dysprosium oxide / ferrite alloy, and a certain percentage of manganese to produce super magnetostriction. (3) The crucible element used to measure the pressure, the test proves that the crucible element has high sensitivity in the calibration pressure range, and at the same time opens up a new way for the application of pressure measurement in helium. (4) a resin based filler molar cavity, commonly used in the past to replace amalgam alloy. (5) Japanese researchers have successfully completed the preparation work ytterbium-doped gadolinium gallium garnet embedded waveguide laser line to complete the further development of laser technology it makes sense for this work. In addition, germanium is also used in phosphor activators, radio ceramics, electronic computer memory elements (magnetic bubble) additives, and glass fiber fluxes, as well as optical glass additives.
î´î´ 1878, Charles (Jean Charles) and Marley Trignac (G.de Marignac) discovered a new rare earth elements in the "erbium", this element by the Inuit will (Ytterby) named as ytterbium (Ytterbium). î´
