Abstract

Silicon anodes promise revolutionary lithium-ion battery energy density, yet commercial viability remains constrained by catastrophic volume expansion and interfacial degradation under demanding thermal conditions. Here, we demonstrate engineered crack pinning mechanisms within a gradient-structured hybrid solid-electrolyte interphase (H-SEI) that enables unprecedented cycling stability of micro-sized silicon anodes across extreme temperatures. The dual-layer H-SEI architecture features nanocrystalline inorganic domains providing grain-boundary strengthening, while polymer-integrated outer layers incorporate distributed nanocrystals as crack arresters, preventing fracture propagation through synergistic stress redistribution. This crack pinning strategy maintains structural integrity under ~200% volumetric expansion, preserving continuous wide-temperature lithium-ion transport. Paired with NCM811 cathodes, 1-Ah pouch cells exhibit long cycle life, retaining >80% capacity from −20 °C to 70 °C over extended cycling, substantially exceeding existing silicon technologies. These findings establish crack pinning as a transformative approach for thermally-robust silicon batteries, enabling next-generation energy storage across diverse environmental conditions.
裂纹固定使宽温锂离子电池的微尺寸硅阳极稳定循环
硅阳极有望带来革命性的锂离子电池能量密度,但在苛刻的热条件下,其商业可行性仍然受到灾难性的体积膨胀和界面退化的限制。在这里,我们展示了在梯度结构的混合固体-电解质界面(H-SEI)内的工程裂纹钉钉机制,该机制使微尺寸硅阳极在极端温度下具有前所未有的循环稳定性。双层H-SEI结构的特点是纳米晶无机畴提供晶界强化,而聚合物集成的外层包含分布的纳米晶作为裂纹拦阻剂,通过协同应力重分布防止裂缝扩展。这种裂纹钉住策略在~200%的体积膨胀下保持了结构的完整性,保持了连续的宽温锂离子输运。与NCM811阴极配对,1-Ah袋电池具有较长的循环寿命,在- 20°C至70°C的延长循环中保持80%的容量,大大超过现有的硅技术。这些研究结果表明,裂纹钉接是热坚固硅电池的一种变革性方法,可以在不同的环境条件下实现下一代储能。
