Low Barriers and Faster Electron/Ion Transport Rates through the GaO/MnCO Anode with a Heterojunction Structure for Lithium-Ion Batteries.

Electrode stability can be controlled to a large extent by constructing suitable composite structures, in which the heterojunction structure can affect the transport of electrons and ions through the effect of the interface state, changed band gap width, and the electric field at the interface. As a promising electrode material, the Ga-based material has a conversion between solid and liquid phases in the electrochemical reaction process, which endows it with self-healing properties with the structure and morphology. Based on these, the GaO/MnCO composite was successfully synthesized with a heterogeneous structure by introducing a Ga source in the hydrothermal process.

GaO Quantum Dots with N-Doped Amorphous Carbon Fixed for Efficient Storage and Transfer of Lithium Ions by Introduction of Dopamine Hydrochloride.

The GaO anode has great potential due to its self-healing and high theoretical capacity in lithium-ion batteries. Like anodes with other transition metal oxides, the GaO anode has the problems of structural change and low electrical conductivity. The electrochemical performance of the GaO anode still needs to be improved.
