Technical-economical evaluation for distributed storage applications. An Italian case study for a medium-scale public facility
2014
Time-of-use energy cost management involves the use of storage by customers to reduce their electricity bills. This can be accomplished by charging the storage during off-peak time periods, when electricity energy prices are low, and discharging it during times when on-peak energy prices are applied. This article addresses the question whether it is economically viable to install medium-scale distributed storage devices in the power system designed to lower the electricity cost for a customer-side application, assuming flexible electricity tariffs. The technical/economical evaluation is carried out referring to Lithium ion (Li-ion), Sodium Sulphur (NaS) and Vanadium Redox Battery (VRB) tech…
NANOSTRUCTURED ANODE MATERIAL FOR Li-ION BATTERY OBTAINED BY GALVANIC PROCESS
2016
The accumulation of energy by batteries plays a fundamental role for the production of electrical energy and for its efficient management. Between different storage systems the lithium-ion battery are considered very interesting. Although they are now a well-established commercial reality, they are still subject of vigorous research efforts, in order to make improvements primarily in terms of costs, safety and energy density. The latter is in fact still low compared to that of fossil fuels, if you think to the automotive field. In particular efforts are focused towards the identification of valid alternatives to the electrode materials so as to overcome the limitations and extend the use of…
Optimized morphology and tuning the Mn3+ content of LiNi0.5Mn1.5O4 cathode material for li-ion batteries
2023
The advantages of cobalt-free, high specific capacity, high operating voltage, low cost, and environmental friendliness of spinel LiNi0.5Mn1.5O4 (LNMO) material make it one of the most promising cathode materials for next-generation lithium-ion batteries. The disproportionation reaction of Mn3+ leads to Jahn–Teller distortion, which is the key issue in reducing the crystal structure stability and limiting the electrochemical stability of the material. In this work, single-crystal LNMO was synthesized successfully by the sol-gel method. The morphology and the Mn3+ content of the as-prepared LNMO were tuned by altering the synthesis temperature. The results demonstrated that the LNMO_11…
Ab initio calculations of Li2(Co, Mn)O8 solid solutions for rechargeable batteries
2019
The presented study has been financed via the Latvian Science Council Grant No. 2018/2-0083. The author is grateful to Professors M. R. Philpott, G. Ceder and G. Borstel for many stimulating discussions during his work at Singapore. We performed all our ab initio calculations at North German Parallel Computer Center located at Hannover (HLRN).
