The basic knowledge in battery research bridging the gap between academia and industry was reviewed by the authors from both fields. In the first half, the importance of three technological parameters in practical batteries is shown, i.e., (1) cathode loading, (2) anode/cathode pairing, and (3) electrolyte amount. We explain these key parameters in detail by showing several examples of the current lithium-ion batteries and lithium metal batteries in the literature with the aim of circulation of this key technological knowledge into academia, especially in the field of materials science. In order to clarify the correlation between the three key parameters and the energy density, simulations are carried out using a 1 A h pouch cell for a lithium-ion battery, i.e. graphite/LiNi_0.8Co_0.1Mn_0.1O₂ (NCM811), and three types of lithium metal batteries (Li/NCM811, Li/S, and Li/O₂). The resultant energy densities, when the three key parameters are varied, are compared for these systems. In the second half, we survey representative reports on fundamental battery science mainly provided by academia, which contributed to the advancement of modern battery knowledge. However, this knowledge is necessary to be brought to our society assessed by the technological criteria used in industry, which are shown in the first half. In addition to the above discussions, we provide a cell simulator to calculate practical energy densities, which can be found as an Excel file in the ESI, and therefore it is free to access.

电池研究的基础知识弥合了学术界与行业之间的鸿沟

这两个领域的作者都对电池研究的基本知识进行了弥补，以弥补学术界和工业界之间的差距。在上半部分，显示了三个技术参数在实际电池中的重要性，即，（1）阴极负载，（2）阳极/阴极配对，以及（3）电解质量。我们通过在文献中显示当前锂离子电池和锂金属电池的几个示例来详细解释这些关键参数，目的是将这种关键技术知识传播到学术界，特别是在材料科学领域。为了阐明三个关键参数与能量密度之间的相关性，使用锂离子电池的1 A h袋式电池（即石墨/ LiNi）进行了模拟_0.8 Co _0.1 Mn _0.1 O ₂（NCM811）和三种锂金属电池（Li / NCM811，Li / S和Li / O ₂）。当三个关键参数发生变化时，对于这些系统，将比较所得的能量密度。下半年，我们调查了学术界主要提供的有关基础电池科学的代表性报告​​，这些报告对现代电池知识的发展做出了贡献。但是，必须通过上半年显示的工业中使用的技术标准将这些知识带入我们的社会。除了上述讨论之外，我们还提供了一个单元模拟器来计算实际的能量密度，可以在ESI中的Excel文件中找到它，因此可以免费访问。
