Germany's new bipolar plate can save 80% of battery materials -Lithium - Ion Battery Equipment
According to foreign media, recently, Germany's Fraunhofer Institute of Environmental Security and Energy Technology developed a new "bipolar plate". The equipment can be used for bipolar battery, and the newly developed bipolar plate can save 80% of the material consumption.(Lithium - Ion Battery Equipment)
According to the R&D personnel, the new bipolar plate uses conductive polymer, which has extremely thin physical properties, and can save a lot of material consumption compared with the traditional battery cell with traditional wiring. In addition, this material has strong corrosion resistance and plasticity, and it can also seal the battery housing through welding technology.
In fact, the welding technology is not applicable to the traditional bipolar plate, because the material is affected by thermal stress and mechanical force, which not only can not achieve the ideal sealing effect, but also takes up a lot of space. However, the new bipolar plate shows excellent flexibility and hardness by adjusting the composition proportion of raw materials during the manufacturing process.
Dr. Anna Grev é, a researcher at the Fraunhofer Energy Technology Research Institute, said that the new bipolar plate was made of a mixture of conductive polymer and graphite, accounting for 80% and 20% of the total. Dr. Anna Grev é said that the secret lies in the proportion of raw materials, and the production process is not very different from the processing method of ordinary polymers.
