'Before 2012, the battery can't be used basically. ' 'The battery before 2014 can't be used basically.' 'The battery before 2015 can't be used basically.'
With respect to the use of electric vehicles for power battery cycles, professionals are always in a headache. Old batteries are not easy to use. The difference in years of judgment is only due to the different degree of harshness of battery quality. Enthusiastic environmentalists are also a headache, whether it is 2012 or not. , 2014, or the 2015 production of power batteries, have been or immediately retired.
From the beginning of use, the power battery capacity will continue to decay. The battery is attenuated to less than 80% of the initial state, the work for providing power to the car will be difficult to do. At this time, the battery still has a life span and can be used in some batteries. In high scenes, this is the principle of using ladders. The industry has enthusiasm for using cascades, mainly based on two points: First, to reduce the cost of lithium batteries, and second, to be environmentally friendly, to find a place for old batteries.
However, these two aspirations are not easy to implement. According to the current technology and process, it is necessary to complete the steps of dismantling, testing, screening, reorganization, etc. to achieve the utilization of power batteries. The cost is high. Many companies have done this. The cost of the trial is very high. If the used batteries are not purchased or the price is extremely low, the utilization of the ladders has certain economical efficiency. Otherwise, the cost of the ladder utilization and the cost of the new battery do not differ much. However, if there is a certain degree of economic efficiency, the batteries are used for the steps. The quality is not optimistic. The battery technology continues to improve, and the quality difference between the old battery and the new battery is getting larger and larger before and after three or five years. This makes the use of batteries for ladders lack of cost-effectiveness.
The use of a ladder to provide access to old batteries is temporary. If the use of ladders is economical, the power battery can be used for several years more, and the material recovery and detoxification treatment can be done later. If there is no economy, the enterprise is more favorable with new batteries. The processing problems will immediately be in sight. According to industry insiders, at the current level of technology, there is no good solution for recycling. In other words, recycling economy is also not good.
It is a somewhat gratifying fact that the use of ladders finds suitable application scenarios on communication base stations. Communication base stations generally need to be configured with backup power to ensure continuous and stable operation during power outages. Backup power supplies generally have small capacity and old batteries. The difficulty of regrouping is small, and the cycle life requirement is not high. The old battery can reach. The old battery has lower cost than the new battery, which is beneficial to the company's cost reduction. The problem of cost performance is solved on the backup power supply of the communication base station.
In January 2018, China Iron Tower Co., Ltd. signed agreements with 16 companies including BYD, Yinlong New Energy, Waterma, Guoxuan Hi-Tech, and Thornton New Energy to cooperate on the recycling of power batteries for new energy vehicles. After more than two years In the pre-pilot study, Tower Company began to use large-scale ladder-by-cell batteries for communication base stations. The Tower Company has 1.8 million communications base stations throughout the country, which has the potential to help China consume large-scale decommissioning power batteries.
However, other than the iron tower company, other companies intending to try are still plagued by economic problems. Regardless of whether or not the use of ladders is feasible, the ultimate harmless treatment must be faced.
One way to solve this problem is to establish a producer extended liability system. Whoever produces, who is responsible for the end. In some European countries, the price of daily used dry batteries is much higher than China, because companies have the obligation to dispose of old batteries, they will handle The cost is transmitted to consumers. In the field of electric vehicles, China's government management departments are also building such a system. If recycling is still not economical in the future, electric vehicles may increase their prices accordingly.
Whether it is the government or the consumer who expects the price reduction of electric vehicles, if it is really a day for price increases for environmental protection, are people willing to accept it?
