“…Presently, the rate capability and energy density of metal-ion batteries are insufficient to satisfy the ever-increasing demand for large-scale stationary energy storage systems. Therefore, rechargeable lithium-ion batteries (LIBs) with large reversible capacity, high energy storage density, and good cycling stability are urgently demanded for new-generation batteries . Among all of the explored candidates of anode materials, two-dimensional (2D) materials with single chemical constituent have attracted great attention due to their high surface-volume ratio as well as the fast metal-ion diffusion along their surfaces. − Monocomponent layered nanosheets show some required properties of energy storage devices; however, none of them can offer all of the required properties.…”

The heterostructured electrodes assembled with various two-dimensional materials break the limitation of the restricted properties of individual building blocks and combine the advantages of single material systems. Here, we design a novel blue phosphorus (BP)/borophene heterostructure by combing BP and borophene monolayers together. We investigate the adsorption and diffusion of Li along the outside surfaces and the interlayer of BP/borophene to assess its suitability as the Li-ion battery anode material. It is revealed that the BP/borophene heterostructure possesses excellent structural stability and high mechanical stiffness. In contrast to the semiconductor character of pristine BP monolayer, BP/borophene is metallic. The adsorption energy of Li on the BP side of the BP/borophene heterostructure is higher than that on the BP monolayer, and Li adsorption on the borophene side of the BP/borophene system is also stronger than that on the borophene monolayer. In addition, the BP/borophene heterostructure possesses a specific capacity of 1019 mA h g–1, which is larger than those of pristine BP monolayer and other BP-based heterostructures. Moreover, it is found that the energy barriers are relatively low as Li diffuses in the BP/borophene. Given these advantages, that is, large adsorption energies, low diffusive energy barriers, high capacity, and electrical conductivity, we conclude that the BP/borophene heterostructure can be an excellent candidate as anode material for Li-ion batteries.

“…In recent years, the sales volume of electric vehicles has increased rapidly year by year, which has formed a complete industrial chain and technology chain and is gradually in the trend of cost slowing down. The product iteration of the new system is very fast, including the use of new materials for batteries, the use of silicon carbide for motors, the lightweight design of chassis and whole vehicle, and the system integration technology [5][6][7]. High integration is the trend of current industry, and high integration will also affect the change of our battery standards and test evaluation objects.…”

“…Lithium-ion battery (LIB) is regarded as a kind of clean energy system with high energy density and long lifecycle, which is widely applied in electric vehicles (EVs) and grid storage. , Because the continuous development of electric transportation technologies put forward higher requirements for the endurance distance of EVs, it is necessary to further improve the energy density of LIBs. , With the technological breakthroughs of electrode materials, such as lithium nickel cobalt manganese oxide (NCM) cathodes and silicon anodes, , the energy density of batteries in current traction battery products has been significantly enhanced. , Some outstanding monomer products are already able to exceed an energy density of 300 Wh kg –1 . , However, for application in EVs and grid storage, the priority of ensuring safety is higher than performance. , Moreover, with the concept of the echelon utilization of traction batteries, how to ensure the safety of batteries over the whole lifecycle, such as “vehicle use then grid storage,” is a key development direction of power battery technologies. , …”

With the continuous improvement of the energy density of traction batteries for electric vehicles, the safety of batteries over their entire lifecycle has become the most critical issue in the development of electric vehicles. Abuse of electricity encountered in the application of batteries has a great impact on the safety of traction batteries. In this study, focused on the overdischarge phenomenon that is most likely to be encountered in the practical use of electric vehicles and grid storage, the impact of overdischarge on battery performance degradation is analyzed by neutron imaging technology and its safety hazards is systematically explored, combined with multimethods including electrochemical analysis and structural characterization. Results reveal the deterioration of the internal structure of traction batteries due to the overdischarge behavior and play a guiding role in the testing and evaluation of the safety of traction batteries.
