1 Introduction. Lithium-ion batteries (LIBs) have been extensively applied in portable electronics and renewable energy storage devices because of their high energy density, long lifetimes, and high operation voltage. [] However, it is presently urgent to develop LIBs with higher energy density (>350 Wh kg −1 at cell level) to meet the demands from the large-scale
Anode, as one of most crucial components in battery system, plays a key role in electrochemical properties of SSBs, especially to the energy density [7, 16].Graphite is a commercially successful anode active material with a low lithiation potential (∼0.1 V vs. Li/Li +) and excellent cycling stability.However, the relative low specific discharge capacity of graphite

As a result, even when paired with a high-voltage cathode (LiNi 0.8 Co 0.1 Mn 0.1 O 2, NCM811) (Figure 1a), the energy density of graphite anodes falls far short of market demand. Recently, silicon-based lithium-ion battery anodes showed encouraging results, as they can offer high capacities and long cyclic lifetimes.
In order to increase the energy density of the lithium battery, better anodes and cathodes are still required. Considering the above, it is interesting to note that the voltage rise on the silicon shown in Fig. 4b is noticeable in cycles 25 and 50 as well, but not in cycle 102, which presumably can be the result of the poorer lithiation

Silicon (Si), the second-largest element outside of Earth, has an exceptionally high specific capacity (3579 mAh g −1), regarded as an excellent choice for the anode material in high-capacity lithium-ion batteries. However, it is low intrinsic conductivity and volume amplification during service status, prevented it from developing further.
Lithium–silicon batteries are lithium-ion batteries that employ a silicon -based anode, and lithium ions as the charge carriers. Silicon based materials, generally, have a much larger specific capacity, for example, 3600 mAh/g for pristine silicon.
Lithium-silicon batteries also include cell configurations where silicon is in compounds that may, at low voltage, store lithium by a displacement reaction, including silicon oxycarbide, silicon monoxide or silicon nitride. The first laboratory experiments with lithium-silicon materials took place in the early to mid 1970s.
