Advancements in structural engineering are expected to enhance the wide-range commercial application of lithium-ion batteries by enabling the implementation of thicker cathode materials. Increasing the thickness of these cathodes can yield significant increasements in gravimetric energy density while concurrently lowering manufacturing costs. These improvements are pivotal to the successful commercial deployment of sustainable transport systems. However, several substantial barriers persist in the adoption of such microstructures, including performance degradation, manufacturing complexities, and scalability concerns, all of which remain open areas of investigation. This review delves into the obstacles associated with current modifying techniques in thick cathodes and explores the potential opportunities to develop more robust and thicker cathodes, while ensuring long-term performance and scalability. Finally, we provide suggestions on the future directions of thick cathodes to promote their large-scale application.
结构工程方面的进展有望通过采用更厚的阴极材料来促进锂离子电池在广泛商业领域的应用。增加这些阴极的厚度可以显著提高重量能量密度，同时降低制造成本。这些改进对于可持续交通系统的成功商业部署至关重要。然而，在采用这种微观结构方面仍然存在几个重大障碍，包括性能下降、制造复杂性和可扩展性问题，所有这些仍然是有待研究的领域。本综述深入探讨了与当前厚阴极改性技术相关的障碍，并探索了开发更坚固、更厚阴极的潜在机会，同时确保长期性能和可扩展性。最后，我们对厚阴极的未来发展方向提出建议，以促进其大规模应用。
