(National Laboratory Astana, 2022-08)
Graphite anode is admitted as one of the critical limiting factors for applying lithium-ion batteries (LIBs) in low-temperature (LT) environments. As an alternative, tin compounds, such as SnO2, exhibit much better LT ...

(National Laboratory Astana, 2022-08)
One of the main challenges in cathodes at low temperatures (LT) is associated with low electronic and ionic conductivity. Graphene can be used to increase electronic conductivity, but most of the experimental methods for ...

(National Laboratory Astana, 2022-08)
Tin selenide-based materials are considered to be promising high-capacity anode materials for Li-ion batteries (LIBs) owing to their non-toxicity, earth-abundance, and chemical stability. However, SnSe suffers from a large ...
