Current status. Preliminary investigation of physical and electrochemical properties of [LTO/Si]@C composite prepared by solid-state synthesis is performed. Also, the test synthesis of this composite by spray pyrolysis was carried out. Gathered results enable to conclude that combining the LTO and silicon indeed greatly improves the properties of the composite in comparison with the properties of individual components by balancing their advantages and disadvantages. Therefore, the proposed composite is a promising anode material for new generation LIBs.

The structure, morphology and homogeneity of the composite are the key factors for improving the properties of lithium-ion batteries, and the way a composite is synthesized determines these properties. The method of synthesizing nanomaterials by using spray pyrolysis is unique, so it allows the synthesis of powder materials with significantly improved properties for practical use. Also, it is a key technology to achieve controlled synthesis of microparticles with a homogeneous structure and morphology required to produce electrode materials with high performance.

The project’s influence on progress in this area. The development of safe, affordable and environmentally friendly electrode materials with excellent electrochemical characteristics for LIBs is a determining factor in the advancement of renewable energy technologies, portable electronic devices and electric vehicles and their large-scale proliferation. In this project, we offer innovative and practical concepts for the new composition of the [LTO/Si]@C composite. The ultimate aim is the use of the [LTO/Si]@C composite as an anode for the new generation "super-capacity" lithium-ion batteries. Preliminary tests have confirmed that the proposed composite material [LTO/Si]@C, obtained by spray pyrolysis, has a substantially higher capacity energy storage and improved mechanical stability, and has a higher electrochemical capacity and low cost compared with existing commercial anode materials. The proposed method involves the use of spray pyrolysis as a practical method capable of creating a composite with superior structural and morphological properties. Also, spray pyrolysis is a fairly simple method for scaling up to industrial production. Successful implementation of this project involves a significant impact the quality of life, both economical and social. This is because this project focuses on areas such as the renewable energy storage systems, environmentally friendly transport, communication tools, security, etc., which are key technologies in the sustainable development of modern society.
