A research team at the University of Genova has developed the spin quantum battery, an energy storage system that uses the spin degrees of freedom of particles. The battery utilizes the spin properties of particles for energy storage and release, with a distinctive charging method that eliminates the need for an external field.
The principle of the device is numerically implemented in the 2D material phosphorene as an example, and first-principles calculations give excellent qualitative agreement with the physics of the PGE. The 2D spin battery is interesting as it is both a device that generates pure spin currents and also an energy source that harvests photons.
"In this framework, my officemate Niccolò Traverso Ziani focuses on the study of analytically solvable quantum spin chains, while I study quantum batteries—miniaturized devices able to store energy exploiting quantum mechanical principles.
Ferraro and his colleagues at University of Genova were ultimately able to extend their investigation of spin quantum batteries to a regime with a very large number of elements. This is a goal that had so far been impossible to achieve using common approaches for designing spin quantum batteries.
"The main results of our work include the exploration of an alternative charging protocol for spin quantum batteries, which is based on time-dependent modulation of one of the system's internal parameters, and the possibility to study this protocol on the limit of a very large number of elements composing the device," said Ferraro.

The Comisión Nacional De Energia (CNE) of the Dominican Republic announced the start of work on the Dominicana Azul solar project shortly in late December (22 December).
Immersed liquid-cooled battery system and temperature control system to reduce temperature differences between battery cells, improve safety, and extend battery life. The system uses a coolant that surrounds the battery packs in the battery cabinet.
The enclosure can also be filled with dielectric fluid to further submerge the cells. Immersion cooling energy storage battery cabinet to improve heat exchange efficiency and stability of immersion cooled battery systems. The cabinet has a housing with an accommodating cavity for the battery module.
Immersed liquid-cooled battery system that provides higher cooling efficiency and simplifies battery manufacturing compared to conventional liquid cooling methods. The system involves enclosing multiple battery cells in a sealed box and immersing them directly in a cooling medium.
The system involves submerging the batteries in a non-conductive liquid, circulating the liquid to extract heat, and using an external heat exchanger to further dissipate it. This provides a closed loop immersion cooling system for the batteries. The liquid submergence and circulation prevents direct air cooling that can be less effective.
A cooling system that operates on a DC power supply such as a thermoelectric cooler would not be susceptible to black-outs or brown-outs, allowing the ambient temperature of the battery back-up system to be kept constant.
A lithium battery pack immersion cooling module for energy storage containers that provides 100% heat dissipation coverage for the battery pack by fully immersing it in a cooling liquid. This eliminates the issues of limited contact cooling methods that only cover part of the battery pack.
Typically, the larger the battery cabinet's electrical capacity, the larger the size of each individual battery and the higher the room's DC voltage. Depending on the location of the base station, temperatures may range from a high of 50°C to a low of -30°C.

A research team at the Paul Scherrer Institute PSI has developed a new sustainable process that can be used to improve the electrochemical performance of lithium-ion batteries.
New insights into a dry-coating-processed surface engineering strategy are revealed. Coating amount dominates the structural evolution of the surface coating layer. The hybrid coating layer is tuned to reach an optimal cycling and safety performance. Ambient storage stability and slurry preparation for practical use are also improved.
Surface coatings have proved to be effective to suppress these unwanted surface reactions. Thus, improvement in the performance of lithium-ion batteries in terms of capacity retention, long term cycling, thermal stability, and high-temperature stability can be achieved using surface coatings.
Surface coating, a prominent strategy in this domain, involves applying a stable layer on the electrode surface to prevent continuous electrolyte decomposition, thus enhancing ICE and cycle life. The choice of both coating methods and materials significantly impacts the electrochemical performance, marking this as a critical area of research.
The primary role of such coatings is to act as a protective passivation film which prevents the direct contact of the cathode material and the electrolyte, thus mitigating the detrimental side reactions that can degrade the battery performance.
Not constrained only to Ni-rich cathode system, the wisdom can literally be generalized to a wider context in battery industry, where surface coating tunability can be achieved by scrutinizing the chemical evolution and heuristic structural evolution that enabling further improvement of material performances.
Coatings typically based on oxides, phosphates, polymers, ionically conductive materials and in specific cases certain cathode materials are employed to improve the electrochemical performance of battery cathode materials. The role of coatings in minimizing detrimental electrolyte-cathode side reactions was also discussed briefly in the review.
The price of lithium-ion battery packs has dropped 14% to a record low of $139/kWh, according to analysis by research provider BloombergNEF (BNEF). This was driven by raw material and component prices falling as production capacity increased across all parts of the battery value chain, while demand growth fell short of some industry expectations.
Last year, energy experts noticed a change in lithium-ion battery pricing predictions. Battery pack prices went up by 7%, reaching $151/kWh. Yet, prices varied greatly around the world. In China, prices stayed low at $127/kWh. But, the US and Europe had much higher prices, by 24% and 33% respectively.
