Qingdao Energy Institute has developed a high-performance cobalt-free lithium-rich manganese-based cathode material system

With the development of electric vehicles, there is an increasing demand for long-life power lithium batteries

As one of the important elements in power battery cathode materials, cobalt plays an important role in stabilizing the material structure and improving cycle and rate performance

Recently, Wu Jianfei's research group has achieved cobalt-free based on lithium-rich cathode materials and developed a high-performance cobalt-free lithium-rich manganese-based cathode battery system, which reduces the cost of cathode materials and further improves the electrochemical performance of lithium-rich cathode materials

The development of the cobalt-free lithium-rich manganese-based cathode material system realizes the real cobalt-free cathode material, reduces the cost of the cathode material, improves the cycle stability of the lithium-rich manganese-based cathode material, and inhibits the voltage plateau during the cycle.
