简介目录

单电池二次电池由单极电极组成，集流体的两侧均由相同的电极材料製成，所有电极浸入相同的电解液中。由于每个电极均使用外部连接线并联连接，因此电池系统包含大量惰性材料。结果，估计体积能量密度将损失约40%，重量能量密度将损失约20%。

双极电池具有简单的电池结构和形状，因为它们不使用电连接器或其他配件。电池的体积接近各个单元电池的堆迭厚度乘以单元电池基板面积的总和，电池的重量相当于所有组件的总质量。双极电池的容量等于单一单元电池的容量，但双极电池的输出电压由串联单元电池的数量乘以每个单元的电压决定。

在电池中使用双极电极显着提高了体积和重量能量密度。此外，基于以应用为中心的设计，可以轻鬆调整电池形状，以最大限度地利用目标装置中的电池储存空间。换句话说，透过减少电池体积和最小化BMS，可以透过最小化电池封装材料的使用来同时追求提高能量密度和降低成本。这最终可能促使电动车在有限的电池空间中安装更多电池，从而延长行驶里程。因此，双极性电极的这些优点对于行动电子设备和电动车中使用的二次电池的设计非常有吸引力。

双极电极的另一个优点是电子电流垂直流过基板，基板的大横截面积大大改善了电流密度和电流分布。因此，透过使用双极性电极，高速充电电池可以安全地运行，不会有任何安全问题。

从Furukawa Electric的使用双极电极的小型电池开始，近年来Toyota已将双极镍氢电池商业化，并将其安装在 Aqua HEV 中。Toyota于2023年6月宣布，计划在2026年至2027年为大众市场电动车生产双极磷酸铁锂电池，并在2027年至2028年为未来电动车生产双极镍基锂离子电池。此路线图的目标是与高性能 LIB 相比，增加范围并降低成本。

最近推出的Toyota Crown Countryman和LexusRX都配备了传统镍氢电池的改良版本，称为双极镍氢电池。这与使用锂离子电池的传统趋势背道而驰，尤其是在高阶和节能车型。这一转变标誌着该公司打算逐步扩大镍氢电池在整个产品线中的使用，并代表了电池技术采用的策略性变化。

在本报告中，我们对双极电池市场进行了研究和分析，并提供了近年来开始使用的双极电极的发展趋势和研发现状的资讯。

A single-cell secondary battery consisted of monopolar electrodes, where both sides of the current collector are composed of the same electrode material, has all electrodes immersed in the same electrolyte. Since each electrode is connected in parallel using external connecting wires, a significant amount of inactive material has been integrated into the battery system. As a result, it is estimated that the volumetric energy density may experience a loss of approximately 40%, and the gravimetric energy density approximately 20%.

The bipolar battery features a simple cell configuration and shape as it does not utilize electrical connectors or other accessories. The volume of the battery is close to the product of the total stack thickness of the individual unit cells and the substrate area of the unit cell, while the weight of the battery is comparable to the total mass of all components. Although the capacity of the bipolar battery is equivalent to that of a single unit cell, the output voltage of the bipolar battery is determined by the number of unit cells connected in series and the voltage of each cell multiplied together.

Using bipolar electrodes in batteries significantly increases both volumetric and gravimetric energy density. Additionally, based on application-centric design, the battery shape can be easily adjusted to maximize the utilization of the battery storage space in the target device. In other words, the battery volume decreases, and by minimizing the BMS, energy density enhancement and cost savings can be simultaneously pursued through minimized use of cell packaging materials. This ultimately translates into the ability to install more batteries in limited electric vehicle battery mounting spaces, potentially leading to increased driving range. Therefore, these advantages of bipolar electrodes are highly attractive for the design of secondary batteries used in mobile electronic devices and electric vehicles.

Another advantage of bipolar electrodes is that electron flow occurs vertically through the substrate, and when the substrate's cross-sectional area is large, current density and distribution are significantly improved. Therefore, using bipolar electrodes allows fast-operating secondary batteries to function safely without any safety issues.

Starting with Furukawa Electric's compact batteries featuring bipolar electrodes, Toyota has recently commercialized bipolar Ni-MH batteries, which were applied to the Aqua HEV. In the announcement at June 2023, Toyota revealed a roadmap stating that they plan to produce bipolar LFP batteries for volume-grade EVs in 2026-2027 and bipolar Ni-based LIBs for future versions of EVs in 2027-2028. This roadmap aims to enhance driving range and reduce costs compared to performance versions of LIBs.

The recently released Toyota Crown Crossover and Lexus RX feature an improved version of the traditional Ni-MH battery, known as the bipolar Ni-MH. This marks a departure from the previous trend of using LIBs, especially in high-end and fuel-efficient models. This shift suggests an intention to gradually expand the use of Ni-MH batteries across the lineup, indicating a strategic change in battery technology adoption.

In this report, we have compiled the history of the development of bipolar electrodes, which have recently begun to be applied, as well as the current status of research and development. We have detailed each development to provide a comprehensive overview, making it easy to understand the overall situation.
