While lithium-ion batteries dominate the field of high-energy-density applications, a variety of promising alternative battery technologies exist that might be suitable for various application purposes. Their requirements may vary considerably, e.g., for stationary batteries they are significantly different from those of traction batteries in electric vehicles, i.e., low installation and lifetime cost and a long cycle life are the key parameters for the former ones. Here, we review the recent developments of dual-ion battery (DIB) and particularly of dual-graphite battery technologies, which may be considered as sustainable option for grid storage. We present the progress and challenges of DIB materials and electrolytes, especially with respect to performance parameters, e.g., energy density and cycling stability as well as cost. We discuss the major challenges for practical application and critically evaluate the DIB technology along with an assessment of the potential to fulfill the targets for grid storage.

尽管锂离子电池在高能量密度应用领域中占据着主导地位，但仍存在着各种有前途的替代电池技术，这些技术可能适用于各种应用目的。它们的要求可能相差很大，例如，对于固定电池，它们与电动汽车中的牵引电池有很大不同，即，低安装成本和使用寿命成本以及长循环寿命是前者的关键参数。在这里，我们回顾了双离子电池（DIB）的最新发展，尤其是双石墨电池技术的发展，这些技术可能被视为网格存储的可持续选择。我们介绍了DIB材料和电解质的进步和挑战，特别是在性能参数方面，例如能量密度，循环稳定性以及成本。
