In rigorous testing, lithium-ion batteries utilizing this new anode demonstrated exceptional performance and maintained stable operation for over 1,500 rapid charge cycles.
Besides, these batteries also showed a 1.5 times higher energy density compared to those using conventional graphite anodes. This means they could potentially offer longer driving ranges in EVs without increasing battery size.
The breakthrough also holds promise for sodium-ion batteries (SIBs), which are a potentially cheaper and more sustainable alternative.
“Sodium ions generally exhibit poor reactivity with conventional anode materials like graphite or silicon. However, the hard carbon–tin nano-composite structure maintains excellent stability and fast kinetics in sodium environments, underscoring its versatility across multiple battery platforms,” highlighted the press release.
