近年来，随着新能源汽车技术的不断发展和新能源汽车保有量的持续增加，急剧推动了动力电池行业的发展和动力电池技术的发展。In recent years, with the continuous development of new energy vehicle technology and the continuous increase in the number of new energy vehicles, the development of the power battery industry and the development of power battery technology have been sharply promoted.

电池通常在15℃与35℃之间具有良好的工作性能。当工作温度低于15℃时，能源存储和动力输出效率将显著下降。这将大大缩短行驶里程并降低动力性能，并且还缩短使用寿命。此外，特别针对锂电池，锂电池在低温下的充电期间，容易从电解液中释放出锂，从而导致电池的不可逆的能量损失，并且释放的锂可能会穿过隔膜而导致安全事故。Batteries usually have good working performance between 15℃ and 35℃. When the operating temperature is below 15°C, energy storage and power output efficiency will decrease significantly. This will significantly reduce mileage and power performance, and also shorten service life. In addition, especially for lithium batteries, lithium batteries easily release lithium from the electrolyte during charging at low temperatures, resulting in irreversible energy loss of the battery, and the released lithium may pass through the separator and cause safety accidents.

为了解决电池低温下的续航等问题，现有技术中提出了对电池内部采取保温措施的方案。具体地，电池通常采用的是电池模组组装到电池箱体上，形成电池结构。电池模组与电池箱体之间留有缝隙，该缝隙形成了电池模组热量散出的路径。常用的电池保温措施是往该缝隙中填充保温结构，例如泡棉，通过保温结构隔断电池模组的散热路径，但仍然存在保温效果不理想的问题。In order to solve problems such as battery life at low temperatures, existing technologies have proposed solutions to adopt thermal insulation measures inside the battery. Specifically, batteries usually use battery modules that are assembled onto a battery box to form a battery structure. There is a gap between the battery module and the battery box, and the gap forms a path for heat dissipation from the battery module. A common battery insulation measure is to fill the gap with an insulation structure, such as foam, and use the insulation structure to block the heat dissipation path of the battery module. However, there is still a problem of unsatisfactory insulation effect.

经研究发现，导致电池保温效果不理想的问题的原因主要有以下几点：After research, it was found that the main reasons for the problem of unsatisfactory battery insulation effect are as follows:

其一，电池内部结构比较复杂，无法保证保温结构能够完全填满电池模组与电池箱体之间的缝隙；First, the internal structure of the battery is relatively complex, and there is no guarantee that the insulation structure can completely fill the gap between the battery module and the battery box;

其二，电池模组与电池箱体之间的缝隙小，无法用机器填充保温结构，仅能用人工填充，但人工填充操作困难，增加了加工时长，也进一步加重了无法填满的问题。Secondly, the gap between the battery module and the battery box is small, and the insulation structure cannot be filled with a machine. It can only be filled manually. However, manual filling operation is difficult, increases the processing time, and further aggravates the problem of inability to fill.

基于以上考虑，为了解决保温效果不理想的问题，申请人经过深入研究，设计了一种电池，通过在电池模组与容置腔的内壁之间的间隙中填充第一发泡保温层，由于第一发泡保温层具有发泡特性，能够完全填充电池模组与容置腔的内壁之间的间隙，从而有效阻隔电池模组向周围空气散热的路径，进而隔断电池与外界的热传导、热对流和热辐射，大大提升了电池的保温效果。Based on the above considerations, in order to solve the problem of unsatisfactory thermal insulation effect, the applicant has designed a battery after in-depth research. By filling the first foam insulation layer in the gap between the battery module and the inner wall of the accommodation cavity, due to The first foam insulation layer has foaming properties and can completely fill the gap between the battery module and the inner wall of the accommodation cavity, thereby effectively blocking the heat dissipation path of the battery module to the surrounding air, thereby blocking heat conduction and heat transfer between the battery and the outside world. Convection and thermal radiation greatly improve the thermal insulation effect of the battery.
