Among the numerous all-liquid flow batteries, all-liquid iron-based flow batteries with iron complexes redox couples serving as active material are appropriate for long duration energy storage because of the low cost of the iron electrolyte and the flexible design of power and capacity.
Other flow-type batteries include the zinc–cerium battery, the zinc–bromine battery, and the hydrogen–bromine battery. A membraneless battery relies on laminar flow in which two liquids are pumped through a channel, where they undergo electrochemical reactions to store or release energy. The solutions pass in parallel, with little mixing.
Whereas lithium-ion batteries can deliver big amounts of energy in a short period of time (1 to 2 hours), flow batteries have much less power density. That means they are better at delivering a consistent amount of less energy over a longer period of time (up to 10 hours).
Herein, we propose a low-cost alkaline all-iron flow battery by coupling ferri/ferro-cyanide redox couple with ferric/ferrous-gluconate complexes redox couple.
With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.
Liquid cooling, due to its high thermal conductivity, is widely used in battery thermal management systems. This paper first introduces thermal management of lithium-ion batteries and liquid-cooled BTMS.
The lithium-ion battery thermal management system proposed by Al-Zareer et al.119 employs boiling liquid propane to remove the heat generated by the battery, while propane vapor is used to cool parts of the battery not covered by liquid propane.
The media such as liquid, phase change material, metal and air play a significant role in battery cooling systems. [5, 18, 19] As the metal media, micro heat pipe array (MHPA) is commonly used in the lithium-ion battery cooling method due to the characteristics of compactness, and the MHPA can enhance the stability and safety of battery pack.
Fig. 1 (a) shows the schematic diagram of the proposed composite cooling system for energy storage containers. The liquid cooling system conveys the low temperature coolant to the cold plate of the battery through the water pump to absorb the heat of the energy storage battery during the charging/discharging process.
In Shanghai, the ACCOP of conventional air conditioning is 3.7 and the average hourly power consumption in charge/discharge mode is 16.2 kW, while the ACCOP of the proposed containerized energy storage temperature control system is 4.1 and the average hourly power consumption in charge/discharge mode is 14.6 kW.
The proposed container energy storage temperature control system integrates the vapor compression refrigeration cycle, the vapor pump heat pipe cycle and the low condensing temperature heat pump cycle, adopts variable frequency, variable volume and variable pressure ratio compressor, and the system is simple and reliable in mode switching.
Containerized energy storage systems play an important role in the transmission, distribution and utilization of energy such as thermal, wind and solar power [3, 4]. Lithium batteries are widely used in container energy storage systems because of their high energy density, long service life and large output power [5, 6].
