A new galvanic replacement synthetic strategy using metallic Ti as a template for hollow voids is presented and an intriguing hollow interwoven structured Sb/TiO₂ is introduced. The applied Ti can play the triple role of reducing the Sb-ion into Sb, acting as a sacrificial template to generate hollow voids through a structural evolution and behaving as an alternative non-sensitive titanium salt to form TiO₂. Interwoven Sb/TiO₂ can be readily activated and can also buffer drastic volumetric variations during storage of alkaline ions (e.g. Li⁺, Na⁺), thereby demonstrating high capacity and superior cycling ability in rechargeable batteries.

中空交织结构化Sb / TiO ₂颗粒的高碱性离子存储能力：电置换形成机理和体积缓冲作用†

提出了一种新的以金属钛为模板的空心替代电化合成策略，并引入了有趣的空心交织结构化的Sb / TiO ₂。所施加的Ti可以起到将Sb离子还原成Sb的三重作用，充当牺牲模板以通过结构演变生成中空空隙，并充当替代性的非敏感钛盐而形成TiO ₂。交织的Sb / TiO ₂可以很容易地被激活，并且还可以缓冲碱性离子（例如Li ⁺，Na ⁺）存储过程中急剧的体积变化，从而证明了可充电电池的高容量和出色的循环能力。
