翻译一段话

| 首先， 我们开发了一种从废旧锂离子电池中浸出有价金属的新工艺，该浸出工艺解决了当前废旧锂离子电池湿法回收工艺浸出过程中酸利用率低的问题，通过逆流浸出，在最佳工艺条件下可实现连续化作业。其次，我们选取价格低廉易存贮的淀粉作为浸出还原剂代替当前被广泛使用的较昂贵的还原剂H2O2，通过单次循环实验，锂的综合浸出率在98%以上，镍以及钴的综合浸出率在95%以上，锰的综合浸出率在93%以上。 |

将2楼的作些改动，是否更好？ 首先， 我们开发了一种从废旧锂离子电池中浸出有价金属的新工艺，该浸出工艺解决了当前废旧锂离子电池湿法回收工艺浸出过程中酸利用率低的问题，通过逆流浸出，在最佳工艺条件下可实现连续化作业。其次，我们选取价格低廉易存贮的淀粉作为浸出还原剂代替当前被广泛使用的较昂贵的还原剂H2O2，通过单次循环实验，锂的综合浸出率在98%以上，镍以及钴的综合浸出率在95%以上，锰的综合浸出率在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%. 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. |
