Battery researchers are struggling to design viable all-solid batteries, which promise enhanced safety but are currently achievable only at a high cost and with complex cell designs. Now a study on a sulfide-based cathode material demonstrates that a radical redesign of the electrode using 100% active material may help address the issue.
All-solid-state rechargeable batteries with Li2S-based positive electrode active materials have received much attention due to their safety and high capacity. Since Li2S has quite a low electronic ...
Electrodes that have characteristics such as high charge capacity, high rate capability, and high voltage (considered for cathodes) can potentially improve the power and energy densities of Li-ion batteries. The objective of this review is to provide a simple yet comprehensive understanding of LiBs and their electrodes.
This review critically discusses various aspects of commercial electrode materials in Li-ion batteries. The modern day commercial Li-ion battery was first envisioned by Prof. Goodenough in the form of the LCO chemistry. The LiB was first commercialized by Sony in 1991. It had a LCO cathode and a soft carbon anode.
Since Li 2 S has quite a low electronic and ionic conductivity, Li 2 S in the positive electrode is combined with conductive agents, such as conductive carbons and sulfide solid electrolytes, to improve its cycle performance. Recently, we developed a remarkable Li 2 S-based positive electrode active material: Li 2 S–Li 2 O–LiI.
In this regard, LiMn 2 O 4 is considered an appealing positive electrode active material because of its favourable ionic diffusivity due to the presence of three-dimensional Li-ion diffusion channels. However, LiMn 2 O 4 exhibits inadequate rate capabilities and rapid structural degradation at high currents.
