An optimistic – but realistic – perspective for sodium batteries

International researchers have analyzed the potential of sodium-based energy storage and found recent technical advances have arrived faster than those for the lithium-ion batteries which have been studied for three decades. Issues remain, however, before sodium constitutes a complementary option to lithium.

‘European cobalt supply hinges on circular economy’

Amid an uptake in EV sales, researchers are examining battery material supply chains. A report has indicated policy-driven circular economy strategies must be introduced in Europe if the bloc is to strengthen its resilience to volatility in the cobalt market.

Leclanché restructure delayed

Eneris Group has suspended its financial commitments for the time being and Leclanche shareholder Fefam has provided a bridge loan of CHF34 million to give the historic company more time to set up a joint venture for large scale battery cell production in Europe.

How long will the lithium supply last?

Researchers have sounded the alarm. If no serious efforts are made on second-life battery use, recycling and vehicle-to-grid applications, decarbonization efforts may hit the buffers a lot sooner than expected.
