4 reasons why we need alternatives to lithium-ion batteries



  • Lithium just isn’t presently mined on the dimensions we are going to want sooner or later
  • Inadequate world mineral reserves to satisfy projected demand
  • Fears {that a} collapse in world free commerce might harm provides

We urgently want to search out methods to make residing batteries utilizing uncooked supplies apart from lithium, cobalt and nickel.

That is likely one of the conclusions of a report printed final yr by the Geological Survey of Finland (GTK), which is acknowledged as one of many predominant facilities in Europe for the evaluation and analysis of sustainable financial assets. .

The demand for various battery sorts is rising because the storage sector faces a number of main challenges, in line with the report, titled ‘Reworking the Round Economic system right into a Useful resource Balanced Economic system’. Challenges embody:

  1. The world’s vitality transition from fossil fuels to non-fossil fuels is a much bigger process than we expect

Reaching the vitality transition will result in an unprecedented demand for minerals. A lot of the minerals wanted for the transition haven’t been mined in giant portions earlier than. As well as, most of the metals used within the know-how that we hope to drive and speed up the transition face mining provide dangers.

Solid your eye over a periodic desk and you will see references to key elements in rechargeable batteries, together with lithium, nickel, cobalt, manganese, tin, tantalum, magnesium and vanadium. The issue is that many of those minerals have restricted availability and subsequently are prone to future provide. In reality, if we take the instance of zinc, the GTK report highlights that there’s anticipated to be a “severe risk” to the provision of zinc inside the subsequent 100 years.

  1. Present mineral manufacturing just isn’t excessive sufficient to satisfy projected demand, and present world reserves are inadequate to satisfy consumption targets.

We can’t depend on long-term provides of lithium, cobalt and nickel, which kind the premise of most batteries used for vitality storage functions. Now could be the time to start out exploring using various battery applied sciences. However what are these different sorts of know-how? There are all kinds of storage sorts presently in use or in growth – together with compressed-air storage, for instance, and even storage applied sciences that use hemp and seawater.

  1. Mining exercise should improve considerably to acquire the weather wanted for the sorts of batteries presently in widespread use.

The supply of the unprecedented quantity of metals we have to assist the vitality transition is mining. The GTK report stated that “very preliminary calculations” present that the present manufacturing of metals similar to lithium, nickel and cobalt is decrease than the extent that may quickly be wanted. “It’s equally obvious that present world reserves are additionally inadequate,” the report stated. This required a pointy improve within the variety of mines working in a brief interval of just some years. Nonetheless, there’s actually appreciable opposition to any improve in mining exercise resulting from environmental considerations. Lithium mining, for instance, may cause air contamination and soil degradation. The big quantity of water used to extract lithium has additionally led to water-related conflicts involving communities in Chile, for instance.

  1. China’s management of the uncooked supplies worth chain means Europe is prone to lose market share

As of 2019, China immediately controls roughly 80 % of the uncooked supplies worth chain (particularly mining, refining, smelting, manufacturing and recycling). It also needs to be famous that this doesn’t account for the overseas investments that China holds in industrial belongings world wide. The ‘Made in China 2025′ plan “is designed to safe the remaining 20 % for Chinese language pursuits within the identify of long-term safety”, the GTK report. It added that, if this plan is even partially profitable, then Europe can have issue sustaining market share in industrial sectors and can lose its market chief standing in some instances. The report added: “One of many implications (contemplating the US’ strategic responses to this) could possibly be a collapse of worldwide free commerce.”

In abstract, the anticipated growth in vitality storage is principally based mostly on the idea that there might be an enormous raise in lithium-ion batteries. Nonetheless, what is usually ignored in these plans is that we aren’t presently able to ramp up manufacturing of minerals like lithium to the degrees that might be wanted within the close to future. Among the many causes for that is that there’s prone to be widespread opposition to the event of recent mining tasks resulting from environmental considerations.

As well as, as provides of those important minerals are depleted, it’ll turn into tougher – and thus, costlier – to mine these minerals and thus the price of manufacturing will improve.

For that reason, extra consideration and funding ought to be targeted on the event of other sorts of batteries and vitality storage if the nice hope for the vitality transition takes place on the dimensions that all of us so desperately want.
