Abstract

The development of anode materials with high rate performance as well as favourable working durability is key for next-generation lithium-ion batteries (LIBs). Here, MgV3O8 is reported as an advanced anode material, using a facile and scalable solution combustion technology. The MgV3O8 anode shows a "near-zero" volume change (<10% over 1000 cycles). This can be explained by a solid-solution Li+ storage mechanism, leading to superior cycling stability. Consequently, the MgV3O8 electrode achieves a remarkable capacity of approximately 102.6 mA h g-1 at 2.0 A g-1, along with a low fading rate of 0.001% per cycle over 3000 cycles.
