Dual voltage energy storage battery

In summary, we designed a particular dual-ion battery consist of ZnHCF cathode, zinc anode and K/Zn electrolyte which addressed the poor cycling and rate ability issues simultaneously. The K +-ions played vital roles in the redox reaction of ZnHCF cathode and plating/stripping reaction of zinc anode.

The device can purportedly operate for more than 8,000 cycles and deliver up to 98.8% of stored energy. The energy density of the module is around 335 Wh. In low-voltage mode, the storage system can be connected in parallel to form a low-voltage system with up to 105 batteries, providing for a storage capacity of up to 548 kWh.

This paper presents a novel dual-active-bridge (DAB) bidirectional DC–DC converter power management system for hybrid electric vehicles (HEVs). The proposed system makes it possible to charge an additional battery with regenerative power flows and distributes power from the electrical source to the load efficiently.

The 5.3 kWh battery can be used as a wall solution or in a stackable configuration. Thanks to a special casing, up to 15 modules can be stacked without additional components. It measures 580 mm x 463 mm x 155 mm and has a weight of 57.3 kg. The device can purportedly operate for more than 8,000 cycles and deliver up to 98.8% of stored energy.

Rechargeable zinc-based batteries (RZBs) using low-cost zinc metal anodes are feasible for large-scale energy storage, but the developments currently are restricted by the poor performances.
