Lithium-ion battery pack resource recovery and ladder use will be the next new blue sea market. In 2018, it was a large year of massive recycling of lithium-ion batteries. The new energy car lithium-ion battery pack began to retire the large-scale retirement this year.
Then, lithium-ion battery pack resource recovery and ladder use of the problem. How to effectively carry out the ladder utilization and lithium resource recycling of lithium-ion battery packs into the next new blue sea market in my country's battery technology development. First, the future market development trend of waste lithium-ion battery packs: my country has become the world's largest lithium resource consumer.
With the increasing amount of resource demand in lithium-ion battery pack, the contradiction between demand and reserves is gradually highlighted, and the tradder utilization and recycling of waste batteries is increasingly attached to the parties. It is expected that by 2020 global waste lithium-ion battery packs is expected to be as high as 25 billion my country has begun to study in this regard, kinetic analysis by citric acid treatment, developing ascorratic acid to waste lithiature azimine battery pack weight metal ions. Second, lithium ion battery pack resource recovery and ladder utilization process: At present, the recovery process of the waste lithium ion battery pack at home and abroad is: first discharge, then disassemble the battery, the electrode, negative electrode, electrolyte and diaphragm, etc.
Part, then the electrode material is leached, the acid is immersed, and the extraction is performed to achieve the enrichment of the viable metal. The flow of the ladder can be divided into three steps: first screen the recovered lithium-ion battery pack, then carry out the battery's string parallel, the third step is performed, and the BMS, design capacity and power match is added. General battery capacity and power match ratios are 8: 1, the discharge ratio is 0.
125C. Third, the benefits of the secondary use and recycling of lithium-ion battery: the ladder utilization and recycling of lithium-ion battery packs is based on environmental protection, resource savings, and profit can be mapped. Environmental protection: The positive electrode material of the lithium-ion battery pack contains nickel, cobalt, manganese, lithium, etc.
, The electrolytic solution of the lithium-ion battery contains toxic chemical composition, which can also cause fluorofluidity. Savings: Lithium-ion battery packs contain a large number of metal elements, nickel, graphite, etc. It is all distributed in Tibet, Qinghai, Sichuan and other conditions.
The magnesium ion content in salt lake is relatively high, and the difficulty of extracting lithium is also very large. Advantage: The ladder utilization and resource recovery of the lithium ion battery pack can still be commercialized. Very high, metal cobalt price is 600,000 / ton, nickel 100,000 / ton, carbonate 1.
70,000 / ton, metal lithium 900,000 / ton. Fourth, the lithium-ion battery pack market will become the next Blue Sea market: policy support: National ministries and commissions advocate the first step utilization, and then conduct resource recovery; implement producers' responsibility extension, "Who is produced, who is responsible" Establish a recycling system of lithium-ion battery pack, carry out some pilot projects, establish recovery network and information supervision; industry norms are constantly improved, and the national qualification requirements of the company are gradually clear. Lithium-ion battery pack market size: 2018 really started to make a lithium-ion battery pack to recycle new wind, the next rising point.
According to the measurement, in 2018, there will be 11GWH battery retirement, corresponding market space is around 6 billion; 2020 market space is 15 billion, 2023 reached 40 billion, from 2018 to 2023, annual complex increase rate reached 50 %, Can say that the recycling of lithium-ion battery packs will become the next market style. V. Five, lithium-ion battery ladder is three difficulties: Difficulties: Exploring the best groung method, standard module direct ladder use is the best way, single only problem cell leads to the module to disassemble and recombine.
Difficulties 2: Concentrated large-scale energy storage power station security. The large-scale energy storage ladder of lithium iron phosphate cells is feasible, and the centralized storage method of the retired ternary battery is not realistic, suitable for direct resource recovery. Difficulties 3: BMS components aging, aging failure of electronic components should be technical verification.
Sixth, lithium iron phosphate ion battery recovery prospects: Lithium ferrite and lithium battery after retiring can be used as an energy storage battery for at least 5 years. Lithium iron phosphate, if directly scrapped, dismantled recovery, limited earnings, its components are not worth money, lithium content is very small, 1 ton of lithium iron phosphate recycling economic benefits are around 10,000, if used as a ladder utilization earnings at 30000-40000 Around, since these two aspects, lithium iron phosphate is more suitable for the ladder. The material used by the lithium-ion battery pack is lithium iron phosphate.
According to the above, the lithium iron ion battery is suitable for the ladder, so when you buy a lithium-ion battery, you can purchase our lithium iron ion battery pack! Future, lithium Ion battery pack resource recovery and ladder use prospects, will become the next new blue sea market, let us wait and see. .
