“…In addition, the electrode-specific capacitance (C p ) can be calculated on the basis of the size of the oxidation and reduction peak areas. In accordance with the calculation formula for specific capacitance, C p = ∫ i false( v false) d v 2 m υ false( v 2 − v 1 false) (V 1 and V 2 are the starting and ending voltages of the scan, m is the mass of the active material in grams, and υ is the scan rate in V s –1 ), the C p values for the blank, CCB, and Bi 2 O 3 @C-4 negative plates are 33.8, 47.3, and 56.7 F/g, respectively. When the electrode-specific capacitance is larger, the electrode can store more charge.…”

Lead−carbon batteries (LCBs) and conventional lead−acid batteries (LABs) exhibit similar advantages in terms of safety, cost, and stability. The addition of carbon material to the negative plate can considerably alleviate the irreversible sulfation of the negative plate of the battery and significantly extend its cycle life. However, due to the low hydrogen evolution potential of carbon materials, when added to the negative plate, it will cause serious hydrogen evolution. In this paper, porous corn cob biochar (CCB) composites (Bi 2 O 3 @C-4) with high hydrogen evolution potential were prepared by in situ thermal synthesis method on CCB substrate. A large amount of Bi and Bi 2 O 3 adhere to the surface of Bi 2 O 3 @C-4 and occupy the adsorption site of H + , which slows down the hydrogen evolution rate and increases the hydrogen evolution potential. Furthermore, Bi 2 O 3 @C-4 has mesoporous and macroporous structures, which not only enable the storage of electrolytes but also provide channels for ion transport to accelerate the conversion of Pb/PbSO 4 , effectively inhibiting the formation of large PbSO 4 crystals. In addition, the interior of the macropores also offers nucleation sites for the deposition of Pb 2+ . Finally, the effect of Bi 2 O 3 @C-4 as an additive on the performance of LCBs was elaborated. At a discharge rate of 0.1 C, the initial discharge-specific capacity of LCBs with added Bi 2 O 3 @C-4 (167.7 mAh g −1 ) was 47% higher than that of the blank batteries (114.1 mAh g −1 ). The high-rate partial state of charge (HRPSoC) cycle life test with a discharge rate of 1 C results in a cycle life of Bi 2 O 3 @C-4 (36,524 cycles) that is 5.1 times longer than that of a blank battery (7,169 cycles). In conclusion, Bi 2 O 3 @C-4 exhibits a dual synergistic effect of high hydrogen evolution potential and porous structure, which not only reduces the hydrogen evolution rate of the negative plate, but also inhibits the irreversible sulfation of the negative plate, providing valuable insights for enhancing the performance of LCBs.

“…Taking into account the challenge of the modern world, even these batteries continue to be improved and currently efforts are being made to improve the performance of lead-acid batteries and extend their life cycle. One of the examples most often cited in recent articles is to improve the discharge capacity of lead-acid batteries, for example, through the use of graphene oxide [10]. Electricity storage technologies were divided into two groups: batteries and accumulation systems.…”

The pace of the implementation of renewable electricity storage in Europe is disappointingly slow. Several factors influence this and there is a need to speed up the rate and increase the volumes in order to promote a 100% transition to renewable energy resources, expand the practice of using renewable energy, and contribute to the improvement of the quality of life of consumers. An important factor is significantly reducing impact on the environment and climate change. Electricity from renewable energy sources such as solar and wind has a seasonal nature that cannot provide the necessary electricity consumption and cover peak loads. The so-called “energy resource crisis” is also a very topical problem at the moment, which reinforces the global need to increase the share of renewable energy resources in the overall balance of primary energy resources. Practical wider integration of renewable electricity storage is what can help stimulate this. The availability of renewable electricity is constantly increasing, and the level of technological innovation is rapidly developing. Therefore, it is valuable to analyse, look for connections and for ways to accumulate electricity in order to promote its availability from private homes to the national scale and more broadly on the European scale. Therefore, this article analyses and compares the different options for renewable electricity storage, from small batteries to large storage systems, arriving at the best solution according to needs, using analysis methods such as multicriteria decision analysis (MCDA) and TOPSIS. After comparing nine criteria, such as the amount of investment required, existing power density, efficiency, duration of operation, and others in two groups (small and large accumulation systems), it was concluded that lithium-ion batteries are currently the best solution among batteries, while pumped hydro storage is the best solution among large accumulation systems.

Herein, a simple method to prepare porous carbon that inhibits hydrogen evolution is used, which has enormous advantages for both capacitors and lead‐acid batteries. The quantitative filter paper spongy porous carbon (SQFPC) is successfully synthesized by the two‐step method. SQFPC displays a porous, spongy structure with a large specific surface area (1847 m2 g−1). In electrochemical tests, SQFPC exhibits high specific capacitance (244 F g−1 at 1 A g−1) and a capacitance retention rate of 72.5% at 40 A g−1. In addition, the capacity of the battery with 0.5 wt% SQFPC is improved by 57.6% at a discharge rate of 0.1C, and the cycle life under the high‐rate partial state of charge is 9.3 times that of the blank battery. The enhanced battery performance is related to the unique structure and surface functional groups of carbon, which speed up ion movement inside the battery and provide active sites for lead deposition.
