Whether there is any value in the use of decommissioned power battery ladders

In the period of power battery decommissioning, in the economic, safety, marketing and other issues are not clear, whether it is direct recycling, or secondary utilization after recycling, has become one of the more controversial topics in the industry.
Some people believe that the use of batteries for civil use is more commercial value, such as mobile charging treasure, landscape lights, environmental protection lights, etc. , some people believe that the ladder utilization is currently facing higher costs, profit model has not yet been built, security has not been verified, weak profitability and other issues, and do not favor the use of ladders.
At the 2018 International Lithium Power (2018) International Lithium Battery Key Materials Technology Innovation Summit, Professor Li Yan of Central South University said: "From an application point of view, as long as the specific application scenario problem is solved, and with appropriate means, ladder utilization can still be done, or profitable
China
." Li
-ion electricity of high-level industry learned that the current power battery ladder utilization applications are mainly divided into two aspects, one is large-scale energy storage, one is small-scale energy storage.
In the field of large-scale energy storage, mainly power system energy storage systems, such as upper-megawatt-hour energy storage systems, but the current large-scale applications have some difficulty, need to do more verification;
"For the big energy storage sector, the cost of ladder batteries is now too high to be economically valuable," he said. Bao Wei, general manager of Huayou Cycle, said.
in the small-scale energy storage sector, the current industry is doing a better job, and can be profitable mostly used in the civil sector, such as mobile charging treasure, environmental protection lights, solar cells and other products.
It is understood that Grimmie in the decommissioned power battery to do the use of solar cell packages, but also made energy storage battery packs, base stations, in addition, China Tower announced in 2018, will be in the communications base station backup power supply, peak filling valley, microgrid and other fields no longer procurement of lead-acid batteries, gradually through the ladder battery replacement, the current application is good.
the use of ladders has made progress in the field of small energy storage, but in the market, recycling and other links there are corresponding problems.
, head of green beauty, said that although the company is now trying to make use of the ladder, but there is no large-scale application, in the exploration stage. Mainly because the current decommissioned battery pack is not a lot, received mainly test packages;
Li Zhenxuan, project director of the Center for Policy Research at the China Automotive Technology Research Center, said that the use of batteries in some civilian areas, will face the situation that the battery can not be returned, when the traceability system will be broken. For the future ladder battery to go to the problem, power battery recycling traceability management platform will play a regulatory role, adhering to who "ladder" who is responsible for ensuring that the source of the battery can be checked, go to traceable, node control, responsibility can be investigated.
it is worth mentioning that the difference between the cost of the rung utilization battery system and the new battery system is the key to the economics of the rung utilization. In recent years, with the rapid improvement of new battery performance and rapid cost decline, it has undoubtedly become the biggest competitive factor affecting the development of the rung utilization market.
Mr Bowie said: "At present, the price of the ladder battery is about 3 gross 5, and with the cost reduction, it is estimated that the new battery can do 6 gross, 7 gross, if the future continues to decline, the gap between the ladder battery and the new battery slowly narrowed, only the ladder battery price also continued to decline, the use of the ladder is meaningful."
