“…However, these materials undergo a large volume change during intercalation/de-intercalation, which causes large irreversible capacity changes and makes the practical use of the silicon anode difficult. One possible solution is using SiO with a theoretical gravimetric capacity of around 2600 mA h g −1 (Fukuoka et al, 2007;Fukuoka and Ueno, 2013;Liang et al, 2014;Morimoto et al, 2015), which is considered as our estimation target. Detailed physicochemical properties of each type of battery are shown in Table 1.…”

This study evaluates the costs and carbon dioxide emissions associated with the production of various lithium ion batteries using current and more advanced materials. We constructed an evaluation system which enables the user to quantitatively clarify the e ect of each elemental technology on battery performance and production costs. This method allows the evaluation of production costs and CO 2 emissions of present and future batteries in terms of future technology development, production scale-up e ects, and the use of high-performance new materials. As an example, a battery using innovative cathode and anode materials was evaluated by the process design approach. The future production cost and CO 2 emissions for this battery are reduced from 17.5 to 4.6 JPY W h 1 and 161 to 37 g-CO 2 W h 1 , compared to the present batteries, indicating signi cant impacts on energy use. Finally, the important areas in battery research and development are highlighted, and a roadmap for battery technology is proposed.

The wide utilization of lithium-ion batteries (LIBs) prompts extensive research on the anode materials with large capacity and excellent stability. Despite the attractive electrochemical properties of pure Si anodes outperforming other Si-based materials, its unsafety caused by huge volumetric expansion is commonly admitted. Silicon monoxide (SiO) anode is advantageous in mild volume fluctuation, and would be a proper alternative if the low initial columbic efficiency and conductivity can be ameliorated. Herein, a hybrid structure composed of active material SiO particles and carbon nanofibers (SiO/CNFs) is proposed as a solution. CNFs, through electrospun processes, serve as a conductive skeleton for SiO nanoparticles and enable SiO nanoparticles to be uniformly embedded in. As a result, the SiO/CNF electrochemical performance reaches a peak at 20% the mass ratio of SiO, where the retention rate reaches 73.9% after 400 cycles at a current density of 100 mA g−1, and the discharge capacity after stabilization and 100 cycles are 1.47 and 1.84 times higher than that of pure SiO, respectively. A fast lithium-ion transport rate during cycling is also demonstrated as the corresponding diffusion coefficient of the SiO/CNF reaches ~8 × 10−15 cm2 s−1. This SiO/CNF hybrid structure provides a flexible and cost-effective solution for LIBs and sheds light on alternative anode choices for industrial battery assembly.
