Low-cost, scalable energy storage is the key to continuing growth of renewable energy technologies. Here a battery with sedimentary slurry electrode (SSE) is proposed. Through the conversion of discrete particles between sedimentary and suspending types, it not only inherits the advantages of semi-solid flow cell but also exhibits high energy density and stable conductive network. Given an example, the zinc SSE (ZSSE) delivers a large discharge capacity of 479.2 mAh g⁻¹ at 10 mA cm⁻². More importantly, by renewal of the slurry per 20 cycles, it can run for 112 and 75 cycles before falling below 80% of designed capacity under 10 mA cm⁻² (20% DOD_Zn) and 25 mA cm⁻² (25% DOD_Zn), respectively. The lost capacity after cycles is able to recover after slurry renewal and the end-of-life SSE can be easily reused by re-formation. The concept of SSE brands a new way for electrochemical energy storage.

低成本，可扩展的储能是可再生能源技术持续增长的关键。在这里，提出了一种带有沉积浆料电极（SSE）的电池。通过离散颗粒在沉积类型和悬浮类型之间的转换，它不仅继承了半固体流动池的优点，而且具有高能量密度和稳定的导电网络。举例来说，锌SSE（ZSSE）在10 mA cm ^-2时可提供479.2 mAh g ^-1的大放电容量。更重要的是，通过每20个周期更新浆液，它可以运行112和75个周期，然后在10 mA cm ^-2（20％DOD _Zn）和25 mA cm ^-2（25％DOD ）以下降至设计容量的80％以下_锌）， 分别。循环后损失的容量能够在浆液更新后恢复，并且使用寿命短的SSE可以通过重整轻松地重新使用。SSE的概念为电化学储能开辟了一条新途径。
