五、项目简介(中文)
我司储能用超大量容量水性锂钇电池技术是一项从理论创新到工艺实践到产线量产全部都由中国人自主研发的核心技术,该技术的先进性主要体现在电池结构创新和材料创新两方面。在电池结构上,大容量单体电池的耐温性和可靠性都远超小容量的锂电池,由大容量锂电池组成的储能系统的安全性和可靠性也远超小容量锂电池组成的储能系统。比如10兆瓦的储能电站,我司1000Ah型号电池(一颗电池3.3度电)用3000颗串并联即可,而用传统的100Ah锂电池(一颗电池0.33度电)需要30000余颗串并联。可见,大容量电池是最复合目前国家双碳目标下的储能场景。在电池材料上,我司的大容量水性锂电池采用了水性粘结剂材料替代了传统的PVDF+NMP”的油性粘结体系,使得最终形成的电池材料中没有PVDF这样的有毒有害、易燃易爆的物质。锂电制造过程无污染,可以有效回收高达99%的金属材料,且回收材料中的95%可用于再次生。
六、项目简介(英文)
Our super-large capacity water-based lithium-yttrium battery technology for energy storage is a core technology developed independently by Chinese people from theoretical innovation to process practice to production line, the advance of this technology is mainly embodied in the innovation of battery structure and material. In the battery structure, the temperature resistance and reliability of the high-capacity monomer battery are far superior to the low-capacity lithium battery, the safety and reliability of the energy storage system composed of high-capacity lithium battery is far more than that of the energy storage system composed of low-capacity lithium battery. For example, for a 10 MW energy storage plant, our 1000AH model battery (3.3 kilowatt-hours per battery) can be connected in series and parallel with 3000 pieces, conventional 100AH lithium-ion batteries (0.33 kilowatt-hour per battery) require more than 30,000 connected in series and parallel. Thus, high-capacity battery is the most complex current national dual-carbon target under the energy storage scenario. In terms of battery materials, we use water-based binder materials to replace the traditional“PVDF + NMP” oil-based binder system for large capacity water-based lithium batteries, the resulting battery material is free of toxic, harmful, flammable and explosive substances such as PVDF. The lithium electric manufacturing process is pollution-free, and can effectively recover up to 99% of the metal materials, and 95% of the recovered materials can be used for regeneration.
