Fast chargingMaterial improvementThermal issuesCharging optimizationImproving the rate capability of lithium-ion batteries is beneficial to the convenience of electric vehicle application. The high-rate charging, however, leads to lithium inventory loss, mechanical effects and even thermal runaway. Therefore...
Lithium-ion batteries with nickel-rich layered oxide cathodes and graphite anodes have reached specific energies of 250–300 Wh kg−1 (refs. 1,2), and it is now possible to build a 90 kWh electric vehicle (EV) pack with a 300-mile cruise range

Li+ desolvation in electrolytes and diffusion at the solid–electrolyte interphase (SEI) are two determining steps that restrict the fast charging of graphite-based lithium-ion batteries. Here we show that the low-solvent-coordination Li+ solvation struc
Fast charging of lithium-ion batteries is critical to commercial application of electrical vehicles (EV). Recharging lithium-ion batteries using standard charging methods usually takes more than one hour which is considerably longer than refueling an internal-combustion-engine (ICE) car. Fast cha...
Lithium-ion batteries (LIBs) with fast-charging capabilities have the potential to overcome the "range anxiety" issue and drive wider adoption of electric vehicles. The U.S. Advanced Battery Consortium has set a goal of fast charging, which requires charging 80% of the battery's state of cha...

Fast-charging lithium-ion batteries (LIBs) can be achieved using structurally optimized electrodes and electrolytes. Electrolytes largely affect the interfacial structures of electrodes that are critical to reducing charging time of LIBs without sacrificing battery durability. However, most widely used LiPF6...
Interface reaction between lithium (Li) and materials at the anode is not well understood in an all-solid environment. This paper unveils a new phenomenon of constriction susceptibility for materials at such an interface, the utilization of which helps facilitate the design of an active three-dimen...
