Superior Doped Olivine Cathodes for Fast Charge/Discharge Lithium Batteries

In recent years, the lack of high-performing electrical energy storage systems is seriously bottlenecking the operation of appliances in several fields, that include portable electronics, electric automotive, and stationary devices [1]. Until now, lithium batteries (LiBs) are the highest-performing systems that could address satisfactorily all the requirements of such appliances [2]. Indeed, LiBs show a high specific capacity, a high efficiency, and a long lifespan [3]. However, improvements are still needed in the operating potential (that influences the specific energy and power of the LiBs) and in the rate capability properties of the cathodes. Indeed, electric vehicles need high power during acceleration, and a large amount of stored energy to achieve a sufficient mileage.
