The materials used in these batteries determine how lightweight, efficient, durable, and reliable they will be. A lithium-ion battery typically consists of a cathode made from an oxide or salt (like phosphate) containing lithium ions, an electrolyte (a solution containing soluble lithium salts), and a negative electrode (often graphite).
Liquid lithium salts with graphite anodes and composite metal cathodes are the dominant combination for battery cells, with variants using nickel, manganese and cobalt or iron phosphate. These have energy densities of up to 250 kWh/kg, but incremental improvements in the electrolytes and battery materials are constantly driving that up.
6.1.1. Graphite Graphite is perhaps one of the most successful and attractive battery materials found to date. Not only is it a highly abundant material, but it also helps to avoid dendrite formation and the high reactivity of alkali metal anodes.
Rare and/or expensive battery materials are unsuitable for widespread practical application, and an alternative has to be found for the currently prevalent lithium-ion battery technology.

The proposed material has a large active surface area (1479 m 2/g) as well as a significant pore volume (1.14 g/cm3). The material was mixed with sulfur to create cathode material for LIS batteries. The experimental analysis revealed the longest cycling stability and maximum rate capability.
Lithium-ion batteries (LIBs) High energy densities and the long life of Lithium-Ion batteries (LIBs) have made them a promising energy storage device for the present as well as the future. Graphite is a conventional anode material for LIBs but shows very low capacity because of limited intercalation.
