The theoretical specific energy of Li-S batteries and Li-O 2 batteries are 2567 and 3505 Wh kg −1, which indicates that they leap forward in that ranging from Li-ion batteries to lithium–sulfur batteries and lithium–air batteries.
Unlike Li-S batteries and Li-O 2 batteries, currently commercialized lithium-ion batteries have been applied in the production of practical electric vehicles, simultaneously meeting comprehensive electrochemical performances in energy density, lifetime, safety, power density, rate properties, and cost requirements.
For instance, carbonous materials derived from nature biomass materials can be cheap and abundant source of highly conductive additives. It is believed that the combination between biology and battery structure will accelerate practical applications of next-generation lithium-ion batteries.
In recent years, researchers have worked hard to improve the energy density, safety, environmental impact, and service life of lithium-ion batteries. The energy density of the traditional lithium-ion battery technology is now close to the bottleneck, and there is limited room for further optimization.
The theoretical energy density of lithium-ion batteries can be estimated by the specific capacity of the cathode and anode materials and the working voltage. Therefore, to improve energy density of LIBs can increase the operating voltage and the specific capacity. Another two limitations are relatively slow charging speed and safety issue.
Taking the actual driving range of 300 km as example, the energy density of the power battery should be up to 250 Wh Kg −1, while the energy density of single LIBs should be 300 Wh Kg −1. The theoretical energy density of lithium-ion batteries can be estimated by the specific capacity of the cathode and anode materials and the working voltage.
