Silicon possesses a 10-fold specific capacity compared to commonly used carbon-based anodes. The volume instability, among other impediments for practical use of silicon anodes, leads to the rapid decay of the capacity because of poor cyclability. Urgent mechanisms are required to improve lithium-ion storage during cycling and prevent volume …
Research on sodium-ion batteries began in the early 1980''s (Delmas et al., 1980), but the successful commercialization of lithium ion batteries in 1990 distracted the attention from research and development of SIB (Ellis and Nazar, 2012). Since 2010, numerous novel electrode materials for sodium-ion batteries have been reported.

Lithium-ion batteries have become one of the most popular energy sources for portable devices, cordless tools, electric vehicles and so on. Their operating parameters are mostly determined by the properties of the anode material and, to a greater extent, the cathode material. Even the most promising electrode materials have disadvantages, such as large …

Lithium-ion batteries (LIBs) have been broadly utilized in the field of portable electric equipment because of their incredible energy density and long cycling life. In order to overcome the capacity and rate bottlenecks of commercial graphite and further enhance the electrochemical performance of LIBs, it is vital to develop new electrode materials. Transition metal oxides (TMOs) have …
applications. The classification of positive electrode materials for Li-ion batteries is generally based on the crystal structure of the compound: olivine, spinel, and layered [12]. The olivine positive electrodes are materials with more open structures such as LiFePO. 4 (LFP), which delivers an experimental capacity of 160 mAh g-1
The tomography experiment was performed at the beamline ID16B of the European Synchrotron Radiation Facility (ESRF), Grenoble, France, in the frame of proposal CH-6644.

As batteries are used, the materials in them start to break apart; this is what causes the reduction in performance. But, as Professor O''Dwyer and his team discovered in 2015, when a porous version of titanium dioxide was added to a lithium ion battery, the battery materials remained intact after charging and discharging over 5 000 times.
The key to sustaining the progress in Li-ion batteries lies in the quest for safe, low-cost positive electrode (cathode) materials with desirable energy and power capabilities. One approach to boost the energy and power densities of …
