Recently, the research team successfully developed an integrated electrode with triple functions of current collector, anode active material, and membrane , and has been successfully applied to a high-efficiency, low-cost dual-ion battery. This new structure effectively solves the problems of dramatic volume changes and poor cycle performance of high-capacity anode materials during c...

Recently, our group has developed an integrated configuration design for flexible and ultrafast rechargeable dual-ion battery. In this design, the cathode/anode active materials and the positive/negative current collectors are creatively integrated into a porous separator, breaking through the conventional battery structure. This novel design simplifies the fabrication process, and improved t...

As secondary batteries are gradually applied in smart phones, electric vehicles and other fields, the demand for low-cost and high-performance energy storage devices is growing rapidly. Potassium has similar physical and chemical properties to lithium, and it is abundant and cheap compared with lithium. Recently, our research team has developed a novel dual-ion battery based on pot...

With the rapid development of the market scale of portable electronic devices and electric vehicles, the demand for high energy density and low cost secondary batteries is increasingly urgent. Currently, commercial lithium-ion batteries mostly use graphite-based anode materials, which have low specific capacity and compacted density, which limits the further improvement of the en...

Currently, lithium ion batteries (LIBs) have been widely used in intelligent electronic devices, electric vehicles, large energy storage and other fields. However, lithium resource reserves are limited and unevenly distributed; in addition, with the rapid growth of the demand for energy storage devices year by year, the production cost of LIBs rises rapidly. Therefore, it is urgent ...

With the increasingly urgent demand for the high energy density of the lithium ion batteries (LIBs) for intelligent electronic devices and electric vehicles, the energy density of conventional LIBs based on graphite anode is limited. Therefore, it is urgent to develop new LIBs with high-capacity anode materials. Recently, our research team has developed a novel and generalized lith...

  In March 2016, our research team published a new dual-ion battery on the journal of Advanced Energy Materials. Compared with conventional lithium batteries, this new battery has the advantages of low cost, high working voltage, good safety, environmental protection and easy recycling. However, the cycling stability of the battery still needs to be improved owing to the hu...
