Si-alloy negative electrodes for Li-ion batteries
Conventional Li-ion cells use a layered lithium transition metal oxide positive electrode (e.g. LiCoO 2) and a graphite negative electrode.When a Li-ion cell is charged, Li + ions deintercalate from the cathode and simultaneously intercalate into the graphite electrode.

Is Li-Si a promising lithium-containing negative electrode?
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.
Are tisnsb-based negative electrodes suitable for lithium-ion batteries?
Lithiation Mechanism and Improved Electrochemical Performance of TiSnSb-Based Negative Electrodes for Lithium-Ion Batteries Most electronic Supporting Information files are available without a subscription to ACS Web Editions.
When did lithium ion battery become a negative electrode?
A major leap forward came in 1993 (although not a change in graphite materials). The mixture of ethyl carbonate and dimethyl carbonate was used as electrolyte, and it formed a lithium-ion battery with graphite material. After that, graphite material becomes the mainstream of LIB negative electrode .
Can graphite electrodes be used for lithium-ion batteries?
And as the capacity of graphite electrode will approach its theoretical upper limit, the research scope of developing suitable negative electrode materials for next-generation of low-cost, fast-charging, high energy density lithium-ion batteries is expected to continue to expand in the coming years.
What are the limitations of a negative electrode?
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
Can Li-rich Li-Si alloy be used as a negative electrode?
We then examine the feasibility of the Li-rich Li-Si alloy as a Li-containing negative electrode by combining it with a Li-free positive electrode. Commercially available MnO 2 powder was used as the latter. Before constructing a full cell, charge/discharge behavior of MnO 2 is examined with a half cell, as shown in Fig. 6a.
