The High Pressure Injection Technology Research of the Lithium Ion Batteries

锂离子电池具有能量比高、使用寿命长、额定电压高、自放电率低、体积小、高低温适应性强、高功率承受能力强、绿色环保等突出优点,被越来越多消费者青睐,同时,人们对锂离子电池的性能等各方面要求也越来越高。为了克服现有注液技术的缺陷,提出一种新型的高压注液机构,该高压注液机构通过对锂离子电池内部及外部环境同抽真空、加高压和泄压,使锂离子电池在低压和高压两种模式下循环进行注液,从而时实现锂离子电池高压注液过程,有效避免锂离子电池注液过程中的洒液现象,提高了锂离子电池的注液生产效率及注液浸润效果,保证了注液的一致性,为后续保证产品质量一致提供了必要的条件。

Based on the lithium ion battery having the advantage of high specific energy, cycle long life, high voltage, small selfdischarge , small size, High-low temperature adaptable, high rate performance and no pollution, so more and more consumers like. The same time, people has higher requirements on the performance of lithium ion batteries. In order to overcome the defects of existing liquid injection technology, the paper puts forward a new type of high pressure injection liquid, the high pressure liquid injection mechanism of lithium ion battery internal and external environment at the same time of pumping air into vacuum state, high pressure and pressure, make the lithium ion battery at low pressure and high pressure circulation two modes for liquid injection, so as to realize the lithium ion battery of high pressure liquid injection process, effectively avoid sprinkling in the process of lithium ion battery liquid injection fluid phenomenon, improve the efficiency of the lithium ion battery production liquid injection and liquid infiltration injection effect, and ensure the consistency of the liquid injection, create the necessary condition for the follow-up to ensure consistent product quality.
