“…The achieved ICE and initial specific capacity of the P-doped trilayer SiO x /Si/SiO x anodes are markedly superior to the previous results for different Si thin-film anodes, as shown in Figure 3c. [17,36] The rate capability of the cells with varying C rates was measured, as shown in Figure 3d. The trilayer exhibited a higher capacity at all current rates.…”

Initial reversibility and excellent capacity retention are the key requirements for the success of high‐capacity electrode materials in high‐performance Li‐ion batteries and pose a number of challenges to development. Silicon has been regarded as a promising anode material because of its outstanding theoretical capacity. However, it suffers from colossal volume change and continuous formation of unstable solid electrolyte interphases during lithiation/delithiation processes, which eventually result in low initial Coulombic efficiency (ICE) and severe capacity decay. To circumvent these challenges, a new sandwich Si anode (SiOx/Si/SiOx) free from prelithiation is designed and fabricated using a combination of P‐doping and SiOx layers. This new anode exhibits high conductivity and specific capacity compared to other Si thin‐film electrodes. Cells with SiOx/Si/SiOx anodes deliver the highest presently known ICE value among Si thin‐film anodes of 90.4% with a charge capacity of 3534 mA h g−1. In addition, the SiOx layer has sufficient mechanical stability to accommodate the large volume change of the intervening Si layer during charge‐discharge cycling, exhibiting high potential for practical applications of Si thin‐film anodes.

“…Yet another work worth mentioning is the Si on the Ni foam. 3D structured composite anode containing silicon thin film on graphene coated Ni foam was prepared by chemical vapor deposition and magnetron sputtering techniques [32] by Mukanova et al As the main problem of the Si is the huge volume expansion, the 3D structure of the current collector is capable of effectively suppress/ diminish the volume changes, maintaining stable structure upon cycling. Along with this, graphene serves as an additional electrochemically active component and provides improved conductivity.…”

With the rapid development of new and advanced technologies, the request for energy storage device with better electrochemical characteristics is increasing as well. Therefore, the search and development for more novel and efficient energy storage components are imperative. In Kazakhstan there are several groups that were established to conduct research in the field of energy storage devices. One of them is professor Mansurov’s research group with we have a long time fruitful collaboration. Group at Nazarbayev University do research in design and investigation of advanced energy storage materials for high performance energy storage devices, including lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, and aqueous rechargeable batteries, employing strategies as nanostructuring, nano/micro combination, hybridization, pore-structure control, configuration design, 3D printing, surface modification, and composition optimization. This manuscript reviews research on advanced battery materials, provided by Nazarbayev University scientists since the last 10 years.

These approaches revolve around the idea of changing the planar architecture of conventional current collectors to confine dendritic growth or redirect it away from the separator.…”

In this growing age of clean energy and the use of power storage to circumvent the use of traditional fossil fuel technologies, batteries of greater capacity, storage, and power are increasingly becoming indispensable. New chemistries are being developed to increase the capacity of traditional lithium ion batteries and to develop batteries beyond Lithium ion. Promising high capacity cathodes and anodes are developed however their large-scale deployment is hindered due to safety concerns. In this review, we summarize recent progress of lithium ion batteries safety, highlight current challenges, and outline the most advanced safety features that may be incorporated to improve battery safety for both lithium ion and batteries beyond lithium ion. Of particular interest is the issue of thermal runaway mitigation by incorporation of novel nano-materials and advanced technologies.
