不它不是不可避免的,锂电池的生产和持续使用将意味着开发钴、锰和镍从海底结节。 获得足够数量的这些金属从传统基于土地的矿山。 < h2 > < / h2 > 镍两种类型的镍矿化是目前开采:硫化物和氧化物(红土)。 硫化镍更容易治疗比氧化物冶金镍币。一旦开采镍硫化物最初使用浮选厂加工。镍氧化物通常需要治疗在高压锅(矿物质)高压炊具,根据二次矿化高压灭菌器使用酸或氨。 < a href = " https://www.worldatlas.com/articles/top-nickel-producing-countries.html " rel = " nofollow noreferrer " >十大镍生产国< / >: < a href = " https://i.stack.imgur.com/ipDkc.png " rel = " nofollow noreferrer " > < img src = " https://i.stack.imgur.com/ipDkc.png " alt = "在这里输入图像描述" / > < / > 主要红土生产商:印尼、菲律宾、新喀里多尼亚、巴西和古巴。 硫化的主要生产商:加拿大,澳大利亚,俄罗斯。澳大利亚 也丰富的镍红土(氧化物)。 < a href = " https://www.mining.com/top -镍矿商排名- 2017 production/”rel = " nofollow noreferrer " >镍矿业公司< / >: < a href = " https://i.stack.imgur.com/EmrdR.png " rel = " nofollow noreferrer " > < img src = " https://i.stack.imgur.com/EmrdR.png " alt = "在这里输入图像描述" / > < / > 有很多可用的土地建立镍前海床结节需要开采镍。 < h2 > < / h2 > 锰锰是< a href = " https://www.nsenergybusiness.com/features/manganese-producing-countries/ " rel = " nofollow noreferrer " > 12地壳中最丰富的元素< / >。每年生产约1850万吨锰在全球范围内,从 < pre > <代码>南非6.2公吨澳大利亚3.0公吨中国2.9 Mt加蓬1.8吨巴西1.0公吨< /代码> < / pre > 有重要的认识基础锰资源的土地很多年了。 < h2 > < / h2 >钴 < a href = " https://www.nsenergybusiness.com/features/top-cobalt-producing-countries/ " rel = " nofollow noreferrer " > < / >钴目前由八个国家,刚果是主要生产国: < pre > <代码> 100.0刚果kt俄罗斯6.1 kt澳大利亚5.1 kt菲律宾4.6 kt古巴3.5 kt马达加斯加3.3 kt巴布亚新几内亚3.1 kt加拿大3.0 kt < /代码> < / pre > ,有足够的生产和资源的土地为基础的钴不需要开采海底的结节。

< blockquote > Co-Mn-Ni进入一些最高效的锂离子电池的化学 < /引用> 这是正确的。 < blockquote > 很方便从海洋海底Co-Mn-Ni也是现成的。 < /引用> 这是不正确的。方便从谁?With resource extraction, there's no "convenient". There's economic, or not economic.

it seems that polymetallic mining from the seafloor is inevitable

This is incorrect.

Are there other sources of these elements that can be used other than the seafloor?

You're saying this as if we are currently mining seafloor deposits and nothing else.

The other answer provides a comprehensive list of the current production of Ni, Co, and Mn. In short: There's plenty more Ni, Co, and Mn around and there is absolutely no shortage of us running out of that in the coming hundreds of years. On land. Not in the ocean. http://elementsmagazine.org/past-issues/deep-ocean-mineral-deposits/ Most of the stuff is paywalled, but finding the texts online isn't too hard.

Specifically regarding seafloor mineral deposits, Elements Magazine published an issue two years ago outlining some of the prospects, issues, challenges, and promises in the field of seafloor mining.

One of the greatest problems is the enormous environmental impact. If you're mining on land, the environmental impact is pretty much localised to where you are mining. Once you're in the oceans, you're disturbing many kilometre-squares of area. With environmentally conscious consumers and companies, there will be no market. Volvo, for example, are pledging for ethical sourcing of their metals. They will not buy anything produced from the seafloor. Others have followed, or will follow soon. In that case, if there's no market, there's no need for production.
