摘要

PPROBLEM TO BE SOLVED: To provide a bipolar battery capable of preventing overcharge of a unit cell layer, and allowing each unit cell layer to be charged without dispersion. PSOLUTION: In this bipolar battery 30, the bipolar battery 30 is composed by stacking, by interposing electrolyte layers 4, bipolar electrodes 10 each composed by forming a positive electrode active material layer 2 on one surface of a collector 1 and by forming a negative electrode active material layer 3 on the other surface thereof; the material layer 2 contains spinel lithium manganate as a changing electrode active material; and the material layer 3 contains lithium titanate as an unchanging electrode active material. The changing electrode active material has a characteristic significantly increasing voltage as compared with that before reaching the charge capacity (charging rate 100%) of the changing electrode active material when nearly reaching the charge capacity in charging. The unchanging electrode active material has a characteristic changing the voltage at a rate of change equivalent to that before reaching the charge capacity (charging rate 100%) of the changing electrode active material even when reaching the charge capacity in charging.

要解决的问题：提供一种双极性电池，该双极性电池能够防止单元电池层的过充电，并且允许每个单元电池层充电而不会分散。

解决方案：在该双极型电池30中，通过插入电解质层4来堆叠双极型电池30，从而形成双极型电池10，每个双极型电极10通过在集电体1的一个表面上形成正极活性物质层2并通过形成负极活性物质层3的另一面上。材料层2包含尖晶石锰酸锂作为改变电极活性材料。材料层3包含钛酸锂作为不变的电极活性材料。当接近达到充电时的充电容量时，与达到改变电极活性材料的充电容量（充电率100％）之前的电压相比，改变电极活性材料具有显着增加电压的特性。不变的电极活性材料具有即使达到充电时的充电容量也以与达到变化的电极活性材料的充电容量（充电率100％）之前相同的变化率改变电压的特性。
