“…The performance of reused automotive batteries as stationary energy storage has been validated in Europe [64] and China [65], [66]. The common practice of replacing lithium-ion EV batteries with lower than 80% rated capacity is causing serious pollution, while allowing those batteries to participate in energy sharing markets can push forward the sustainable electrification of transportation [67].…”

The development of distributed generation technology is endowing consumers the ability to produce energy and transforming them into "prosumers". This transformation shall improve energy efficiency and pave the way to a low-carbon future. However, it also exerts critical challenges on system operations, such as the wasted backups for volatile renewable generation and the difficulty to predict behavior of prosumers with conflicting interests and privacy concerns. An emerging business model to tackle these challenges is peer-to-peer energy sharing, whose concepts, structures, applications, models, and designs are thoroughly reviewed in this paper, with an outlook of future research to better realize its potentials.

“…A partir de tais estatísticas, nota-se um aumento considerável, na venda e utilização de veículos elétricos e uma tendência de que tais valores continuem aumentando nos próximos anos. Como consequência da disseminação desses veículos, haverá uma quantidade significativa de baterias sendo aposentadas ao atingirem 80% de sua potência nominal (Xu et al, 2021). Caso não seja dado um novo destino para estas peças, podemos ter um cenário mundial caracterizado pelo desperdício econômico (Hossain et al, 2019).…”

Batteries with 80% of their lifespan are increasingly discarded with the popularization of electric vehicles. The aim of the study is to evaluate the use of second life batteries from electric vehicles in residential photovoltaic prosumers systems. Thus, carrying out an investment feasibility analysis considering the changes proposed in the net metering tariff model in Brazil. The operating strategy for a prosumer is optimized, considering real data from a retired second life battery with 70% of its useful life and its degradation in the second life, this ranging from 60% to 50% of its useful life. Four study scenarios were considered according to the absence or presence of Net Metering and the conventional and white tariffs. The results show the attractiveness of this investment when considering the white tariff and the need to extend the battery life by up to 50% for the scenario with conventional tariff.Resumo: Baterias com 80% de sua vida útil serão cada vez mais descartadas com a popularização de veículos elétricos. O objetivo deste estudo é avaliar o uso das baterias de segunda vida provenientes de veículos elétricos em sistemas residenciais de prossumidores fotovoltaicos. Realiza-se uma análise de viabilidade de investimento de acordo com as mudanças previstas no modelo tarifário de compensação no Brasil. A estratégia de operação para um prossumidor é otimizada, considerando dados reais de uma bateria de segunda vida aposentada com 70% de sua vida útil e sua respectiva degradação na segunda vida, indo de 60% a 50% como final de sua segunda vida útil. Quatro cenários de estudo foram considerados de acordo com a ausência ou presença de Net Metering e com as tarifas convencional e branca. Os resultados mostraram a atratividade desse investimento ao considerar a tarifa branca e a necessidade de estender a vida útil em até 50% da bateria para o cenário com tarifa convencional.

processing, and transmission of information. [1][2][3] Moreover, portable and wearable electronics for health monitoring and interactive communication are already widespread in our life. [4,5] Accordingly, the demanding energy for powering these electronics soars with time, especially the distributed and low-powered energy sources. [6,7] At present, the vast majority of power sources for needed electricity are different batteries, [8][9][10] which are widely used owing to their mature processing technology and low manufacturing cost. However, the batteries have the inherent drawbacks of a limited lifetime and capacity. [11,12] And there are some knotty problems of environmental pollution and recycling difficulty [13,14] when wearing out. Therefore, much effort has been devoted to exploring other types of sustainable and green energy sources like solar energy, wind energy, etc., which serve as a complement or replacement. [15] Since invented by Wang et al. [16] in 2012, the triboelectric nanogenerator [17][18][19][20] (TENG) has become the spotlight among researchers with great promising potential to be the following generation of energy. Based on the coupling effects of electrostatic induction and triboelectrification, [21][22][23] the TENG has merits of high efficiency, easy fabrication, various materials, and low cost. [22,[24][25][26] It has witnessed great progress and achievements in micro-nano energy, [27][28][29][30] self-powered systems, [26,[31][32][33][34][35][36][37][38] blue-ocean energy, [39][40][41][42] and high voltage applications. [43][44][45][46][47][48] However, there are some challenges to face for TENG, such as the ultrahigh but unstable voltage (about several thousand volts) and the relatively low current (about microamperes), which greatly hinder its practical applications in daily life of IoT. Meanwhile, as the static charges being fully constrained on dielectric surfaces, the TENG has quite little induced charge transferring in the circuit and low charge density on the surfaces, [49] which limits its power output.To improve the performance of TENG in energy supply, some previous researches have focused on structure optimization, [50,51] material selection, [52] surface modification, [53] and environment control. [54] Through the corona charging, Zhou et al. [55] have enhanced the charge density to 240 µC m −2 . By highly packaged in vacuum, an ultrahigh charge density of 1003 µC m −2 is obtained by Wang et al., [54] yet leading to great difficulty for the device fabrication. Recently, the emerging contact-separated charge pump technology brings with a new bright prospect and a breakthrough to the bottleneck of charge As an emerging harvester for mechanical energy, the ultrahigh and unstable voltage and low surface charge density have limited the practical applications of triboelectric nanogenerators (TENGs). Herein, a charge pumping technology is demonstrated for sliding-mode TENG with voltage stabilization and enhanced current by utilizing unfixed shuttling charges to generate electricit...
