(1) It is highly desirable to develop new electrode materials and advanced storage devices to meet the urgent demands of high energy and power densities for large-scale applications. In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed.
Batteries are electrochemical devices that store energy via chemical reactions. However, detailed information about the intrinsic electrochemical reaction mechanisms in electrode materials is still limited due to their complexity and the negative effects from binders and conductive carbon additives.
Some important design principles for electrode materials are considered to be able to efficiently improve the battery performance. Host chemistry strongly depends on the composition and structure of the electrode materials, thus influencing the corresponding chemical reactions.
However, these promising materials still suffer from some scientific problems and challenges that limit their further applications. For negative materials, lithium metal is the ultimate choice for the anode in an Li battery because of its highest theoretical capacity and lowest electrochemical potential.
For positive electrode materials, in the past decades a series of new cathode materials (such as LiNi 0.6 Co 0.2 Mn 0.2 O 2 and Li-/Mn-rich layered oxide) have been developed, which can provide a capacity of up to 200 mAh g −1 to replace the commercial LiCoO 2 (∼140 mAh g −1).
