Silicon (Si) is considered to be the most promising anode material to replace graphite due to its higher theoretical capacity. Nanotechnology has played an important role in addressing the serious volume changes that occur during the lithium process of Si anode removal. However, the development of Si anodes has not yet reached the industry standard for the next generation of commercial lithium-ion batteries. Nowadays, with the increasing requirements for battery energy density in diverse industries, the use of silicon anode materials to increase energy density, co-utilization of Si, graphite, new binders, and electrolytes has become a commercially viable method to achieve high energy. Therefore, in this review, we emphasize the necessity of using Si/graphite anodes, new binders, and electrolytes at the same time in commercialization and carefully review the development of Si/graphite anodes. The typical Si anode mixed graphite electrode is discussed, and various strategies for constructing Si/graphite composite materials are organized according to their synthesis method. It is particularly noteworthy that we systematically introduce the key factors for the co-utilization of Si/graphite anodes, new binders, and electrolytes. Finally, some suggestions on the practical application of Si/graphite anodes are given.

在实际的高能锂离子电池应用中考虑硅/石墨负极材料的关键因素

由于其较高的理论容量，硅（Si）被认为是最有希望替代石墨的阳极材料。纳米技术在解决硅阳极去除锂过程中出现的体积变化方面发挥了重要作用。但是，Si负极的开发尚未达到下一代商用锂离子电池的行业标准。如今，随着各种行业对电池能量密度的要求不断提高，使用硅阳极材料来提高能量密度，共同利用Si，石墨，新型粘合剂和电解质已成为实现高能量的商业可行方法。因此，在本次审查中，我们强调了使用Si /石墨阳极，新型粘结剂，和电解质在商业化的同时，并仔细回顾了硅/石墨阳极的发展。讨论了典型的Si阳极混合石墨电极，并根据其合成方法组织了各种构建Si /石墨复合材料的策略。特别值得注意的是，我们系统地介绍了硅/石墨阳极，新型粘结剂和电解质共同利用的关键因素。最后，对硅/石墨阳极的实际应用提出了一些建议。特别值得注意的是，我们系统地介绍了硅/石墨阳极，新型粘结剂和电解质共同利用的关键因素。最后，对硅/石墨阳极的实际应用提出了一些建议。特别值得注意的是，我们系统地介绍了硅/石墨阳极，新型粘结剂和电解质共同利用的关键因素。最后，对硅/石墨阳极的实际应用提出了一些建议。
