Dear colleague,

Decarbonization of the energy system is an important way to achieve carbon neutrality. A complete renewable energy system not only requires solar energy and wind energy, more need a suitable energy storage method to truly form a new energy system, power batteries are considered to be the most important storage one of the forms. Improving battery energy density is the key to the development of power batteries, and the Chinese government has put forward in 2025 that the energy density of the single power battery can reach 300 Wh·kg^-1 in the medium term forwarding to 400-500 Wh·kg^-1. Japan's new energy industry technology development agency has specially researched and formulated the "Next Generation of automotive battery technology. It is proposed that by 2030, the specific energy of the energy-based power battery system will be increased to 500 Wh·kg^-1; Currently, the commercial lithium-ion battery cathode materials can not meet above requirements. Since the cathode material provides a source of active substances in lithium-ion batteries, high energy density of the positive electrode is the key to realize the energy density objective of the above development plan.  

Thus, we are interested in the high energy material structure design, synthesis realization,  electrochemical performance and mechanism exploration on the evolution of the coupling relationship between the local geometry of atoms and the redox electric pair of metal ions.

For this, it is important to collect the valuable research materials for different systems and consider their impacts. Research articles and reviews in this area of study are welcome.
