“…The question may arise in the mind of the reader as to why other alloy anodes are being explored, given that silicon has a much higher capacity than other alloy anodes [71][72][73]. The answer that is given and can be generalized to the whole collection of nanotechnology and battery articles is that because nanomaterials are synthesized in different ways and with different morphologies (shapes) in different ways [74][75][76][77][78].…”

“…This high voltage and low capacity both make this anode have very low energy, but it is still one step ahead of silicon in commercial terms. One of the most important features of this anode is the safety issue, because in electric vehicles there are unpredictable conditions, and the other is the long cycle life, and finally its power [ 72 , 73 , 128 – 130 ].

Improving the anode properties, including increasing its capacity, is one of the basic necessities to improve battery performance. In this paper, high-capacity anodes with alloy performance are introduced, then the problem of fragmentation of these anodes and its effect during the cyclic life is stated. Then, the effect of reducing the size to the nanoscale in solving the problem of fragmentation and improving the properties is discussed, and finally the various forms of nanomaterials are examined. In this paper, electrode reduction in the anode, which is a nanoscale phenomenon, is described. The negative effects of this phenomenon on alloy anodes are expressed and how to eliminate these negative effects by preparing suitable nanostructures will be discussed. Also, the anodes of the titanium oxide family are introduced and the effects of Nano on the performance improvement of these anodes are expressed, and finally, the quasi-capacitive behavior, which is specific to Nano, will be introduced. Finally, the third type of anodes, exchange anodes, is introduced and their function is expressed. The effect of Nano on the reversibility of these anodes is mentioned. The advantages of nanotechnology for these electrodes are described. In this paper, it is found that nanotechnology, in addition to the common effects such as reducing the penetration distance and modulating the stress, also creates other interesting effects in this type of anode, such as capacitive quasi-capacitance, changing storage mechanism and lower volume change.

“…[11] proposed energy management based on fuzzy control to achieve power distribution among the SC and battery in a connected-grid microgrid. HESS energy management schemes are different according to the connection structure of the SC and battery, but the basic idea is to use the battery to bear the low-frequency component of the load, and the SC to suppress the high-frequency component [12][13][14].…”
To address the problem of DC bus voltage surge caused by load demand fluctuation in an off-grid microgrid, here, an adaptive energy optimization method based on a hybrid energy-storage system to maintain the stability of DC bus voltage is presented. The adaptive energy optimization method consists of three parts: the average filtering algorithm, extracting fluctuating power in demand load; the supercapacitor terminal voltage control, keeping the terminal voltage of the supercapacitor near reference; and the battery pack balance control, adjusting the charge/discharge to balance the state of charge for battery packs. In this proposed method, after extracting the fluctuating power by the low-pass filter when the demand load fluctuates, the battery packs release the power to offset the low-frequency fluctuation load and the supercapacitor to instantaneously compensate the high-frequency fluctuation power, to prolong the service life of batteries and maintain the stability of DC bus voltage. The effectiveness of the proposed adaptive energy optimization method is validated and is confirmed to maintain the stable operation of the off-grid microgrid, extend the cycle life of batteries in off-grid microgrid simulations and experiments.
“… 4,5 Such technologies also help to control and reduce the cost of electricity, improve the consistency and flexibility of electrical systems, replace aging power infrastructure, and provide consistent power to remote areas. 6 However, renewable energy sources are prone to fluctuations. Therefore, energy storage systems will be required to buffer these fluctuations to ensure a stable energy supply.…”
