Batteries have an important role as energy sources with environmental advantages. They offset the negative environmental impacts of fossil fuels or nuclear-based power; they are also recyclable. These attributes have led to increasing research with the aim of improving battery design and environmental impact, particularly regarding their end of life. In addition, there is a desire to improve battery safety as well as design batteries from more sustainable and less toxic materials.
New research shows that aluminium battery could offer several advantages:
Aluminium metal anode batteries could hold promise as an environmentally friendly and sustainable replacement for the current lithium battery technology. Among aluminium’s benefits are its abundance, it is the third most plentiful element the Earth’s crust.
To date aluminium anode batteries have not moved into commercial use, mainly because using graphite as a cathode leads to a battery with an energy content which is too low to be useful.
This is promising for future research and development of aluminium as well as other metal-organic batteries.
New UK battery project is said to be vital for balancing the country’s electricity demand
Work has begun on what is said to be Europe’s biggest battery. The 100MW Minety power storage project, which is being built in southwest England, UK, will comprise two 50MW battery storage systems. The project is backed by China Huaneng Group and Chinese sovereign wealth fund CNIC.
Shell Energy Europe Limited (SEEL) has agreed a multi-year power offtake agreement which will enable the oil and gas major, along with its recently acquired subsidiary Limejump, to optimise the use of renewable power in the area.
In a statement David Wells, Vice President of SEEL said ‘Projects like this will be vital for balancing the UK’s electricity demand and supply as wind and solar power play bigger roles in powering our lives.
The major hurdles for battery design, states the EU’s document, include finding suitable materials for electrodes and electrolytes that will work well together, not compromise battery design, and meet the sustainability criteria now required. The process is trial and error, but progress is being made.

2019 has been declared by UNESCO as the Year of the Periodic Table. To celebrate, we are releasing a series of blogs about our favourite elements and their importance to the chemical industry. Today’s blog focuses on Nickel.
Nickel, a silvery-white lustrous metal with a slight golden tinge may be commonly known as a US five cent coin, however, today nickel is one of the most widely used metals. According to the Nickel Institute, the metal is used in over 300,000 various products. It is also commonly used as a catalyst for hydrogeneration, cathodes for batteries and metal surface treatments.
Nickel in batteries:
Historically, nickel has been widely used in batteries; nickel cadmium (NiCd) and in nickel metal hydride (NiMH) rechargeable batteries. These batteries were used in power tools and early digital cameras. Their success as batteries in portable devices became a stepping stone that led to the significant use of NiMH batteries in car vehicles, such as the Toyota Prius.
The demand for nickel will increase even further as we move away from fossil fuel energy. More energy wll need to be stored in the cathode part of lithium-ion batteries as a result.
Socio-economic data on nickel demonstrates the importance the nickel value chain has on industries, which includes mining through end use to recycling.
The data reflects that globally, the nickel value chain supports a large number of jobs, primarily ones in manufacturing and chemical engineering. The output generated by nickel related industries is approximately €130bn, providing around 750,000 jobs.
Nickel is fully recyclable without its qualities being downgraded, making it very sustainable. It is difficult to destroy and its qualities – corrosion resistance, high-temperature stability, strength, recyclability, and catalytic and electromagnetic properties are enabling qualities required for sustainability.
The predicted mass of the global e-waste mountain by 2021 is > 52m t/year, according to the UN.
Smartphones represent a fraction of global electronic waste. Discarded electronics are one of the fastest growing waste streams, with the UN predicting that the global e-waste mountain will reach over 52m t/year by 2021. Meantime, we are gradually running out of valuable minerals, such as neodymium, terbium and iridium, that are crucial in manufacturing electronics.

As the scale of the problem is becoming clear, there has recently been a surge in efforts to understand what goes into electronic products, and how it can be recovered, says Susanne Baker from techUK, the association for companies in the digital economy. ‘We are seeing a lot of academic proposals looking at better understanding the flow of products and waste within the economy,’ says Baker, who heads the trade body’s environment and compliance programme.
