Description
技术领域technical field
本发明涉及锂离子蓄电池技术领域，具体涉及一种一体化设计高功率锂离子蓄电池。The invention relates to the technical field of lithium-ion storage batteries, in particular to an integrated high-power lithium-ion storage battery.
背景技术Background technique
锂离子蓄电池相对于铅酸电池、镉镍电池、氢镍电池具有更高的能量密度、长循环寿命以及更低自放电率等优点，当前已广泛应用于各类电子产品以及新能源汽车领域。Compared with lead-acid batteries, nickel-cadmium batteries, and nickel-hydrogen batteries, lithium-ion batteries have the advantages of higher energy density, long cycle life, and lower self-discharge rate. They have been widely used in various electronic products and new energy vehicles.
目前商品化生产的高功率锂离子电池主要采用卷绕和叠层方式生产电芯，而卷绕工艺制备的圆柱形电芯存在电流密度分布不均匀，电池内阻高，发热量大等缺陷。而叠层方式生产的电芯具有内阻小，极化小等优势。At present, commercially produced high-power lithium-ion batteries mainly use winding and stacking methods to produce cells, while cylindrical cells prepared by the winding process have defects such as uneven current density distribution, high internal resistance of the battery, and large heat generation. The battery cells produced by stacking have the advantages of small internal resistance and small polarization.
许多应用场合，如纯电动汽车，在车辆启动时需要很大的启动电流，刹车时需要在很短的时间内回收能量，因此要求动力电池能够瞬时大电流工作。而此时传统锂离子电池受限于结构原因，内部极柱与极耳处导流面积狭窄，从而导致电流无法快速通过，限制了锂电池的倍率性能；同时，由于电池内阻很大，电极的极耳发热严重，导致电池温度不可控升高，会造成安全性以及循环寿命的重大隐患。Many applications, such as pure electric vehicles, require a large starting current when the vehicle is started, and energy needs to be recovered in a short time when braking, so the power battery is required to be able to work with a high current instantaneously. At this time, the traditional lithium-ion battery is limited by the structure, and the conduction area at the internal pole and tab is narrow, which leads to the inability of the current to pass through quickly, which limits the rate performance of the lithium battery; at the same time, due to the large internal resistance of the battery, the electrode The tabs of the battery are seriously heated, which leads to an uncontrollable increase in the battery temperature, which will cause a major hidden danger to safety and cycle life.
因此，需要提供一种能够极大提高锂离子电池的功率性能的一体化设计的电池结构，以进一步拓展其应用领域。Therefore, it is necessary to provide an integrated battery structure that can greatly improve the power performance of the lithium-ion battery, so as to further expand its application field.
