In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
The metallic lithium negative electrode has a high theoretical specific capacity (3857 mAh g −1) and a low reduction potential (−3.04 V vs standard hydrogen electrode), making it the ultimate choice of negative electrode material for high energy Li-based rechargeable batteries 1, 6, 7, 8.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
For achieving durable and high-energy aqueous Li-ion batteries, the development of negative electrode materials exhibiting a large capacity and low potential without triggering decomposition of water is crucial. Herein, a type of a negative electrode material (i.e., Li x Nb 2/7 Mo 3/7 O 2) is proposed for high-energy aqueous Li-ion batteries.
Due to the smaller capacity of the pre-lithiated graphite (339 mAh g −1 -LiC 6), its full-cell shows much lower capacity than the case of Li 21 Si 5 (0.2–2 μm) (Fig. 6b), clearly indicating the advantage of the Li-rich Li-Si alloy as a promising lithium-containing negative electrode for next-generation high-energy LIBs.
Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives. The breakthroughs of electrode materials are on the way for next-generation batteries.
