Are lithium-ion batteries a viable energy storage solution?

Lithium-ion batteries (LIBs) have become one of the main energy storage solutions in modern society. The application fields and market share of LIBs have increased rapidly and continue to show a steady rising trend. The research on LIB materials has scored tremendous achievements.

Can aqueous based cathode slurry be used for battery production?

Although the aqueous-based cathode slurry is easy to be transferred to the current coating technology without extra cost, the sacrifice of capacity and cycle stability is not acceptable for battery production. Solvent-free manufacturing emerges as an effective method to skip the drying process and avoid the organic solvent.

What is the potential for Battery Integration Technology?

However, the potential for battery integration technology has not been depleted. Increasing the size and capacity of the cells could promote the energy density of the battery system, such as Tesla 4680 cylindrical cells and BMW 120 Ah prismatic cells.

Does micro-level manufacturing affect the energy density of EV batteries?

Besides the cell manufacturing, “macro”-level manufacturing from cell to battery system could affect the final energy density and the total cost, especially for the EV battery system. The energy density of the EV battery system increased from less than 100 to ∼200 Wh/kg during the past decade (Löbberding et al., 2020).

What are lithium ion batteries used for?

Lithium-ion batteries (LIBs) have been widely used in portable electronics, electric vehicles, and grid storage due to their high energy density, high power density, and long cycle life.

Which cathode has better electrochemistry performance and cycle stability?

The studies showed that both calendered LiFePO4 and organic dilithium benzenediacrylate cathode had better electrochemistry performance and cycle stability than the cathodes without calendering (Oladimeji et al., 2016; Oltean et al., 2016).
