Since the commercial success of lithium-ion batteries (LIBs) and their emerging markets, the quest for alternatives has been an active area of battery research. Theoretical capacity, which is directly translated into specific capacity and energy defines the potential of a new alternative. However, the theoretical capacities relied upon in both research literature and industrial/commercial reports are somewhat superficial values. This tiny mistake has overshadowed the potentials of some battery systems while pictured illusive targets for others. Although the battery researchers know the basis of these theoretical values, misinterpretations have caused a severe misunderstanding in the market research and public reports. Therefore, it is of vital importance to highlight the appropriate theoretical capacities, which can make sense in the commercial batteries. The present comparisons clarify that there are serious misconceptions about the advantages and disadvantages of various electrode materials and batteries. From a theoretical perspective (regardless of the performance of available materials), the capacity advantage of Li–S and Li–O2 over LIBs is not as huge as what currently has been pictured. Replacing LIB with a counterpart sodium-ion battery (NIB) is accompanied by only 20% sacrifice in the overall capacity. And NIB has no considerable advantage over potassium-ion battery (KIB) in terms of specific energy.

锂电池的理论容量/能量及其对立
自从锂离子电池（LIB）及其新兴市场在商业上取得成功以来，对替代电池的追求一直是电池研究的活跃领域。直接转化为特定容量和能量的理论容量定义了新替代方案的潜力。然而，研究文献和工业/商业报告中所依赖的理论能力在某种程度上只是表面的价值。这个微小的错误使某些电池系统的潜力蒙上了阴影，而对其他电池系统却提出了虚幻的目标。尽管电池研究人员知道这些理论值的基础，但误解已引起市场研究和公共报告的严重误解。因此，至关重要的是要突出适当的理论能力，这在商用电池中很有意义。本比较结果表明，对于各种电极材料和电池的优缺点存在严重的误解。从理论上讲（无论可用材料的性能如何），Li–S和Li–O的容量优势LIB上的2并没有目前想象的那么大。用相应的钠离子电池（NIB）替换LIB时，总容量仅损失20％。在比能量方面，NIB与钾离子电池（KIB）相比没有明显优势。
