Positive and negative electrode materials of calcium-based thermal batteries

Progress and perspectives of liquid metal batteries

More recently, the desirability for lowering the operation temperature of LMBs has motivated researchers to use fusible materials (e.g. Ga metal, Ga-based alloys, and liquid Na–K alloys) that are in the liquid phase at or near room temperature (0∼40 °C) [32, 33].Among them, Ga-based liquid metals are highly promising because of their safety nature and their moderate

Roles of positive or negative electrodes in the thermal runaway

However, the temperature dependence of ΔT/Δt for a negative electrode material, Li x C 6 [19], [20], [21] is similar with those for LCO [8], [9], [11] and NCA [12], [13]. Hence, the roles of positive or negative electrode materials in thermal runaway are still not fully understood, particularly for LIBs consisting of LCO (NCA) and graphite.

6 FAQs about [Positive and negative electrode materials of calcium-based thermal batteries]

Can calcium zincate be used as a negative electrode?

However, to date, there have been rare reports on the use of calcium zincate as the active material of a negative electrode in a rechargeable zinc–air battery. Herein, calcium zincate was synthesized by a chemical co-precipitation method, and its physical and electrochemical properties were analyzed.

Which positive electrode material is used in high energy density Li-ion batteries?

Additionally, the positive electrode material used in the highest energy density commercial Li-ion batteries contains nickel and cobalt (scarce metals), and this represents the major bottleneck for cost reduction. Reaching high energy densities utilizing Ni and Co free positive electrode materials is a key viewpoint in the calcium technology.

Should Ca-bearing minerals be used as positive electrodes for CA batteries?

Regardless the usefulness of Ca-bearing minerals as positive electrode for Ca batteries, we should underline the importance of the abundant sulfate and carbonate mineral groups as the primary source for the Ca metal anode, which in the end sustain the interest of this technology, cheaper than that based on the Li-ion.

Is calcium a good material for a rechargeable battery?

Calcium is an attractive but poorly studied material for the negative electrode in a rechargeable battery. Here, the authors use a multi-cation binary electrolyte along with an alloyed negative electrode to make a calcium-based rechargeable battery with enhanced stability and reduced operating temperature.

What are the theoretical properties of calcium metal electrodes?

The theoretical properties of calcium metal electrodes, in terms of gravimetric and volumetric specific capacities (Fig. 1 c), overcome those of potassium, sodium (both gravimetric and volumetric) and zinc (gravimetric), and is similar to that of lithium (volumetric), thanks to the favourable combination of intermediate atomic weight and density.
