The lithium era
Due to lithium’s (Li) unmatched combination of lightness and high-energy density, Li-based batteries will dominate the sector for the foreseeable future. Recent advances in the energy density of lithium iron phosphate (LFP) batteries mean that LFP technology will compete increasingly with Li-ion batteries for electric vehicle (EV) and stationary storage applications. Tesla and BYD, among others, are basing some EV models on LFP batteries.
Meanwhile, Li-based batteries are eating into the near-term prospects for lead-acid batteries, which are much bigger and heavier, give off hazardous gases, and are less energy-dense in stationary storage and uninterrupted power supply (UPS) applications. Moreover, the next decade will see lead-acid’s primary market in starting, lighting, and ignition (SLI) systems for internal combustion engine (ICE) vehicles and hybrids increasingly eroded.
Battery materials
Battery cathodes, electrolytes, and anodes are made of cobalt (Co), nickel (Ni), flammable liquids, graphite, manganese (Mn), and Li in the main. Under pressure from rising costs, accessibility, and performance, notably safety pressures, the search is intensifying among cell makers and their component suppliers for ever more effective materials and chemical mixes.
The next two to three years will see Ni increasingly substituted for Co as the cathode stabiliser to break the dependence on costly supplies from the Democratic Republic of the Congo (DRC), even though Ni is not easy to extract and purify. In addition, there will be increasingly urgent efforts to replace flammable liquid electrolytes with ceramic, glass, polymers, or, ideally, silicon electrolytes working in tandem with silicon or Li metal modified anodes.

Improving Battery Performance at Low Temperatures

Advanced Battery Research and Development
Newly published research proposes optimal design elements of aqueous electrolytes for use in low-temperature aqueous batteries.
Energy storage via rechargeable battery technology powers our digital lifestyles and supports renewable energy integration into the power grid. However, battery function under cold conditions remains a challenge, motivating research on improving the low-temperature performance of batteries. Aqueous batteries (in a liquid solution) do better than non-aqueous batteries in terms of rate capability (a measure of energy discharged per unit of time) at low temperatures.
New research from engineers at the China University of Hong Kong, which was recently published in the journal Nano Research Energy, proposes optimal design elements of aqueous electrolytes for use in low-temperature aqueous batteries. The research reviews the physicochemical properties of aqueous electrolytes (that determine their performance in batteries) based on several metrics: phase diagrams, ion diffusion rates, and the kinetics of the redox reactions.
