These issues will inevitably incur short cycling life and severe safety hazards of lithium metal batteries. Herein, a 3D self-supporting host composed of hollow carbon nanofibers incorporated with silicon (Si) nanoparticles inside (Si-HCF) is constructed as Li metal host by a scalable coaxial electrospinning technique.
This core–shell design demonstrates great potential for improving the performance of lithium-ion batteries.
The development of lithium-ion batteries has had a profound impact on the energy storage and electronics industries. Microelectronic devices, including smartphones, digital cameras, and laptops, extensively employ these batteries.
Finally, insights into the future development of smart safer lithium batteries to avoid thermal runaway in terms of consistency, reversibility and adjustability are discussed, offering avenues in the rational design of smart thermally self-protective lithium batteries in the near future.
These materials have both good chemical stability and mechanical stability. 349 In particular, these materials have the potential to prevent dendrite growth, which is a major problem with some traditional liquid electrolyte-based Li-ion batteries.
However, uneven local electric field and lack of lithiophilic sites on the reactive interface cause nonuniform lithium ion (Li +) deposition, leading to Li dendrite growth and parasitic reactions. These issues will inevitably incur short cycling life and severe safety hazards of lithium metal batteries.
