Abstract

A successful solar energy storage is accomplished in a 5 V/5 mAh rated Na-ion battery, which is customized by series connection of three 1.8 V unit cells. The unit cell is constructed with open framework structured Na₂Co_0.5Ni_0.5Fe(CN)₆ positive and Natrium Super Ionic CONductor (NaSICON) type NaTi₂(PO₄)₃ negative electrodes in 1 M Na₂SO₄-SiO₂ hydrogel electrolyte. Both positive and negative active materials demonstrate Faradaic charge storage mechanism with appreciable diffusion coefficients, such as 5.17 × 10⁻¹⁵ and 1.13 × 10⁻¹⁵, respectively. The Na₂Co_0.5Ni_0.5Fe(CN)₆//NaTi₂(PO₄)₃ full cell depicts a specific capacity of 48 mAh g⁻¹ (@ 100 mA g⁻¹), an energy density of 95.68 Wh kg⁻¹ (@ 259.96 W kg⁻¹) and a power density of 779.75 W kg⁻¹ (@ 54.36 Wh kg⁻¹). The cell also exhibits an excellent durability, i.e., 93% capacity retention with 99% Columbic efficiency at 200 mA g⁻¹ upon 1000 cycles. However, the 5 V battery is performance tested under solar-charging cum constant-load-discharging experiment for one-month, and the device describes 85% capacity retention over the period. The good power capability and cycle life with moderate energy density make this battery chemistry suitable for solar energy storage applications.
