People familiar with the battery industry know that lead-acid batteries are easy to recycle, and recycling efficiency, can form a stable cycle of use, which is the lead-acid battery can continue to maintain strong market vitality of the important reasons.
By contrast, lithium-ion battery recycling is difficult, and few people are willing to recycle it. Lead-acid batteries are easy to recover according to incomplete statistics, the first half of this year, 54 power batteries in the middle and lower reaches of the listed companies announced investment expansion plan, total investment of nearly 116 billion. Red to purple lithium batteries, may have a hunch, lithium battery industry is about to usher in the biggest bottleneck of development. Is this bottleneck a cost? Of course, the cost has once become the lithium battery industry to face the biggest challenge, but in many enterprises with painstaking research and development, in recent years, the average cost of lithium batteries has been reduced. Lithium has been plagued by the safety of the industry, in recent years has also ushered in breakthroughs.
Electric vehicle industry is widely concerned about whether lithium batteries can replace lead-acid batteries, in the case of lithium battery cost decreasing and safety increasing, the problem of lithium battery recovery becomes the most crucial step for lithium battery to replace lead-acid battery.
Lithium battery recovery complex cost high Why is it so hard to recycle lithium batteries? The technical route of lithium battery recovery is quite complicated。 The battery must be pretreated first, including discharging, dismantling, crushing and sorting。 After dismantling the plastic and metal housing can be recycled, but costly: because the residual voltage is still up to hundreds of volts (excluding 18650 batteries), there is a certain danger; the battery shell for security needs, encapsulated as not from the form of disassembly, open quite kung fu。 As far as pretreatment is concerned, it must be a losing business。 Lithium battery Cathode materials are also diverse, the mainstream of lithium cobalt acid, lithium manganese oxide, nickel cobalt manganese oxide, lithium iron phosphate and so on。 The metal oxides are extracted by leaching with acid-base solution and then through a variety of chemical processes。 But the ingredients of these oxides have different extraction conditions, and the mixture is more difficult。 The battery is classified according to the cathode material beforehand, and the cost is not low。 Recycling positive metal is already the most profitable part of the battery recycling business。
But the process is too complicated, and the business is deterred。 Now the prices of commodities and non-ferrous metals and rare earths are all in the doldrums, and it is not a good deal to recycle the metal in these ways, let alone the more troublesome waste treatment afterwards。 According to the current technical level, a single liquid treatment is enough to eat the poor recovery of metal proceeds。 The business of turning around is done and no one is doing it。 Under the current technical conditions, no company will voluntarily put into the recycling industry。 Then there is only one way to deal with it passively。 The reason for this situation is not the lithium battery itself, but the current technical means。 If, in the next few years, a lucrative recycling industry cannot be built, lithium-ion batteries will become "time bombs"。 And the first, naturally, lithium battery production enterprises。
A few days ago, the Ministry of Technology and the Development and Reform Commission jointly issued the "Electric Vehicle power battery recycling technical policy" for the first time clear the subject of responsibility, and the logic of pollution control is the same: who produces who is responsible, who pollution who governance.
From a policy point of view, such a regulation is to avoid the trouble of responsibility, and for the lithium battery industry, this rule is precisely missing the enterprise is a crucial point: how to Profit. If the lithium battery recovery in the past two years to usher in a major technological breakthrough, lithium batteries instead of lead-acid batteries will be truly realized.
