Process engineers in China’s lithium battery and environmental sectors are seeing salary growth that outpaces almost every other engineering discipline. […]
Formation is the most time-consuming step in lithium battery manufacturing. A typical NMC cell spends 12-36 hours in formation —
China’s “dual carbon” goals — peak carbon by 2030, carbon neutrality by 2060 — are no longer just political slogans.
> 很多厂长拼命省电费、省药剂费，一年省个十万八万。但他们不知道：污泥含水率只要差5个百分点，处置费可能多花一倍。这笔账，算明白的人不多。 — 2019年我给一家化工厂做废水站改造方案。 厂长跟我说：”王工，我们这个站电费太高了，你帮我们看看怎么省。” 我看了一圈。风机是变频的。水泵是高效节能的。曝气器也是刚换的微孔曝气。电费确实没什么好省的了。 然后我问了一句：”你们污泥含水率多少？” 厂长愣了：”啊？” “污泥。脱水后的泥饼。含水率多少？” “…不清楚。应该是80%左右吧。” 我去脱水机房看了一眼。板框压滤机出泥，用手一捏——湿漉漉的。拿到实验室一测：含水率86%。 “你们污泥怎么处置的？” “外运焚烧。一吨一千二。” “一年多少吨？” “大概2000吨。” 我来回算了一下。他们一年在污泥处置上花了240万。如果含水率降到80%，一年只要140万。 省了100万。 厂长听完，沉默了几秒。然后说：”我们为了省电费，搞了三年，省了不到30万。” — 污泥含水率：最被低估的成本变量
