In this chapter, an attempt is made to focus on the progress made in the field of cathode materials for lithium ion batteries (LiBs) in recent years in terms of achieving high energy and power density, and good capacity retention over multiple cycles and safety.
Evaluate different properties of lithium-ion batteries in different materials. Review recent materials in collectors and electrolytes. Lithium-ion batteries are one of the most popular energy storage systems today, for their high-power density, low self-discharge rate and absence of memory effects.
Lithium ion batteries or LiBs are a prototypical electrochemical source for energy storage and conversion. Presently, LiBs are quite efficient, extremely light and rechargeable power sources for electronic items such as digital cameras, laptops, smartphones and smartwatches.
In addition, four further commercial rechargeable lithium metal batteries namely Li/MoS 2 (Moli Energy [81, 82]), Li/V 2 O 5 (Toshiba ), Li/V 3 O 8 (cell operating at 80–120 °C and based on a polymer electrolyte [30, 83]), and Li/MnO 2 (Tadiran [84, 85]) were introduced.
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.
Anode materials and structures In addition to cathode materials in LIBs, anode materials play a crucial role in advanced batteries. Graphene has been known as one of the most popular anode materials in LIBs.
Energy density vs. specific energy plot of today''s LIBs (dark blue) in comparison to energy-optimized LIBs (light blue), classical Li-metal batteries (CLIMs; green) and post-lithium ion technologies such as lithium/sulfur (Li/S) as well as …
