In situ formation of an intimate solid-solid interface by reaction between MgH<inf>2</inf> and Ti to stabilize metal hydride anode with high active material content

Publisher：Journal of Magnesium and Alloys

MgH2 and TiH2 have been extensively studied as potential anode materials due to their high theoretical specific capacities of 2036 and 1024 mAh/g, respectively. However, the large volume changes that these compounds undergo during cycling affects their performance and limits practical applications. The present work demonstrates a novel approach to limiting the volume changes of active materials. This effect is based on mechanical support from an intimate interface generated in situ via the reaction between MgH2 and Ti within the electrode prior to lithiation to form Mg and TiH2. The resulting Mg can be transformed back to MgH2 by reaction with LiH during delithiation. In addition, the TiH2 improves the reaction kinetics of MgH2 and enhances electrochemical performance. The intimate interface produced in this manner is found to improve the electrochemical properties of a MgH2-Ti-LiH electrode. An exceptional reversible capacity of 800 mAh/g is observed even after 200 cycles with a high current density of 1 mA/cm2 and a high proportion of active material (90 wt.%) at an operation temperature of 120 °C. This study therefore showcases a new means of improving the performance of electrodes by limiting the volume changes of active materials.

TiH2-based anode: In situ formation of solid electrolyte for high volumetric energy density with minimal content of conducting agent

Herein, we report the fabrication of an electrode composite with an ultra-high active material content (90 wt%). This composite was possible because of the utilization of TiH2 as an anode active material that forms a solid electrolyte (LiH) in situ and functions as an electronic conductor, enabling a substantial reduction of the amount of conductor additive in the electrodes. The electrochemical performance of the TiH2-based electrodes with a high active material content was comparable to that of electrode composites that include a solid electrolyte because of sufficient Li+-ion conduction pathways provided by the LiH formed in situ. To further increase the capacity of the TiH2-based electrode, MgH2 (theoretical capacity: 2036 mAh/g) was mixed with TiH2 to function as an active material. TiH2, which is known to exhibit high electron conductivity and a high density, is expected to be used as a partial substitute for low-density carbon additives to increase the volumetric energy density of batteries and their active material content. Hence, the xMgH2-(1 − x)TiH2-AB (AB: acetylene black) electrode composite exhibited a high active material content (90 wt%) and improved volumetric energy density (1687 Wh/L, based on the anode) compared with a MgH2-AB (70:30 wt%) electrode composite (1157 Wh/L), even when the AB content of the xMgH2-(1 − x)TiH2-AB composite was 10 wt%. In addition, a MgH2-TiH2-VGCF (VGCF: vapor-grown carbon fiber) based electrode composite exhibited the highest volumetric and gravimetric energy density (2154 Wh/L, 1888 Wh/kg) among the investigated composites, facilitated by sufficient electron pathways provided by VGCF.

Electrode thickness dependence of charge -discharge performance and reaction distribution of an in-situ- formed solid electrolyte for MgH 2 anodes

Chen, YX; Inoishi, A; Yoshii, K; Sato, H; Okada, S; Sakaebe, H; Albrecht, K

ELECTROCHIMICA ACTA 485 2024.5 （ ISSN:0013-4686 eISSN:1873-3859 ）

Publisher：Electrochimica Acta

MgH2 conversion anodes are considered promising anode active materials for use in lithium batteries because of their high theoretical lithium storage capacity and suitable redox potential. In a previous study, MgH2 was clarified to function as an anode material that forms a solid electrolyte in situ and to work without an electrolyte added to the composite electrode because of the in situ formation of LiH with an ionic conductivity of 10−7 S cm−1 at 120 °C. In the present study, to improve the energy density, cells with thick MgH2 electrodes were prepared and the reaction mechanism was investigated. With increasing thickness of the MgH2 electrode from 84 to 420 μm, the capacity decreased from 1628 to 425 mAh g−1 and the initial lithiated areal capacity was constant among cells with electrodes thicker than 140 μm. In addition, the unreacted MgH2 was found to be mainly distributed near the current collector by ex situ XPS (X-Ray Photoelectron Spectroscopy) measurement. This result differs substantially from that observed for a thick Mg(BH4)2 anode, which can self-generate LiBH4 with a high ionic conductivity of 10−3 S cm−1. The results of the present study indicate that the ionic conductivity of the in-situ-formed electrolyte strongly influences the relationship between battery performance and electrode thickness of an anode that forms an electrolyte in situ.

Authorship：Principal investigator

運輸部門におけるCO2排出量削減に貢献するとともに、我が国の自動車・蓄電池関連産業の競争力を維持・向上することをねらい、現行の電気自動車に搭載されているリチウムイオン電池を性能・コストの両面で凌駕する革新型蓄電池の研究開発を実施する。本事業では、資源制約・調達リスクが無く安価な材料（銅、鉄、亜鉛、炭素等）を使用し、高エネルギー密度化と安全性の両立が可能な「フッ化物電池」と「亜鉛負極電池」を研究開発の対象とする。また、早期実用化に資する材料開発～電池設計・試作～特性評価・解析に係る共通基盤技術の研究開発を産学官連携で取り組む。この中で九州大学ー産総研ー山口大学の連携で鉄系の正極材料の高性能化を進める。
