| 首先， 我們開發(fā)了一種從廢舊鋰離子電池中浸出有價(jià)金屬的新工藝，該浸出工藝解決了當(dāng)前廢舊鋰離子電池濕法回收工藝浸出過程中酸利用率低的問題，通過逆流浸出，在最佳工藝條件下可實(shí)現(xiàn)連續(xù)化作業(yè)。其次，我們選取價(jià)格低廉易存貯的淀粉作為浸出還原劑代替當(dāng)前被廣泛使用的較昂貴的還原劑H2O2，通過單次循環(huán)實(shí)驗(yàn)，鋰的綜合浸出率在98%以上，鎳以及鈷的綜合浸出率在95%以上，錳的綜合浸出率在93%以上。 |

First of all, we developed a new process for leaching valuable metals from waste lithium ion batteries. The leaching process solves the problem of low acid utilization rate in the current wet recovery process of waste lithium ion batteries. By countercurrent leaching, continuous operation can be realized under the optimal process conditions. Secondly, we selected starch, which is cheap and easy to store, as the leaching reducing agent to replace H2O2, a relatively expensive reducing agent widely used at present. Through a single cycle experiment, the comprehensive leaching rate of lithium is above 98%, the comprehensive leaching rate of nickel and cobalt is above 95%, and the comprehensive leaching rate of manganese is above 93%. 發(fā)自小木蟲Android客戶端 |

We developed a new process for leaching valuable metals from waste lithium ion batteries which solves the problem of low acid utilization rate in the current wet recovery process. Continuous operation can be realized by countercurrent leaching under optimal (process) conditions. Besides, we replaced the currently widely used but quite expensive reducing agent H2O2 with starch which is cheaper and easier to store. Through a single cycle experiment, the comprehensive leaching rates of lithium, nickel and cobalt, and manganese were above 98%, 95%, and 93% respectively. |

| Firstly, we have developed a new process for leaching valuable metals from used lithium-ion batteries. This leaching process solves the problem of low acid utilization during the leaching process of the current waste lithium ion battery wet recovery process. Continuous operation can be achieved under the optimum process conditions. Secondly, we choose low-cost and easy-to-store starch as a leaching reducing agent to replace the more expensive reducing agent H2O2, which is widely used. Through a single cycle experiment, the comprehensive leaching rates of lithium, nickel, cobalt, and manganese were above 98%, 95%, 95% and 93% respectively. |
