No, no... let's invest in nuclear power stations instead, which are consistently billions over budget and decades later than planned. That's the only possible option.

UK’s green power industry receives surprise £10bn pledge

Thu 7 Mar 2024 06.00 GMT

Britain’s under-pressure green power industry has received a surprise fillip after a renewables developer pledged to plough £10bn into what would become the largest portfolio of battery storage projects in the country.

NatPower, a UK startup that is part of a larger European energy group, is poised to submit planning applications for three “gigaparks”, with a further 10 to follow next year.

Battery storage projects are seen as a key part of the jigsaw to decarbonise Britain’s power grid, allowing electricity generated by wind turbines and solar panels to be stored for use when weather conditions are still or not sunny.

The NatPower investment would lead to the construction of 60 gigawatt hours of battery storage, with solar and wind projects also in the pipeline.

The two gigaparks would be located in the north of England, with a further site in the west of the country planned later this year. The projects would be built on industrial land, and also through leasing deals with farmers.

Argonne National Lab Breakthrough Cathode Innovation for Sodium-Ion Batteries

Argonne National labs has a new cathode material for sodium-ion batteries.

Johnson’s team invented a layered oxide cathode tailored for sodium-ion batteries. This variation on the NMC cathode is a sodium nickel-manganese-iron (NMF) oxide with a layered structure for efficient insertion and extraction of sodium. The absence of cobalt in the cathode formula mitigates cost, scarcity and toxicity concerns associated with that element.

New advance in all-solid-state battery technology enhances performance of lithium from the bottom

A research team has successfully enhanced the performance and durability of all-solid-state batteries. This breakthrough was made possible through the implementation of a novel approach known as bottom electrodeposition. Their research has been published in Small.

Secondary batteries generally rely on liquid electrolytes when used in various applications, such as electric vehicles and energy storage systems. However, the flammability of liquid electrolytes poses a risk of fires. This prompts ongoing research efforts to explore the use of solid electrolytes and the metal lithium (Li) in all-solid-state batteries, offering a safer option.

In the operation of all-solid-state batteries, lithium is plated onto an anode, and the movement of electrons is harnessed to generate electricity.

During the charging and discharging process, lithium metal undergoes a cycle of losing electrons, transforming into an ion, regaining electrons, and being electrodeposited back into its metallic form. However, indiscriminate electrodeposition of lithium can quickly deplete the available lithium, leading to a significant reduction in the battery's performance and durability.

To address this issue, the research team collaborated with the POSCO N.EX.T Hub to develop an anode protection layer composed of a functional binder (PVA-g-PAA) for all-solid-state batteries. This layer exhibits exceptional lithium transfer properties, preventing random electrodeposition and promoting a process of 'bottom electrodeposition.' This ensures that lithium is uniformly deposited from the bottom of the anode surface.

A research team led by Prof. Chen Wei from the University of Science and Technology of China (USTC) of the Chinese Academy of Science (CAS) revealed for the first time the important role of halogen-mediated solvation structure in the de-solvation process of multivalent ions. The research result was published in Joule.

The team managed to use manganese metal batteries (MnMBs) as the research platform to fully demonstrate the important role of halogen-mediated (with Cl as the main research object) mechanism in lowering the overpotential of the multivalent metal ions deposition and enhancing the Coulombic and the dissolution/deposition efficiencies.
