In this research, we present a report on the fabrication of a Lithium iron phosphate (LFP) cathode using hierarchically structured composite electrolytes. The fabrication steps are rationally designed to involve different coating sequences, considering the requirements for the electrode/electrolyte interfaces.
The steps involved in producing the lithium iron phosphate cathode material are illustrated below. LFP is mainly produced industrially in a single-stage thermal process, which is divided into the sub-processes of grinding and calcination as well as the final application to the cathode.
The production processes are listed below and are primarily divided into a wet process based on PE and a dry process based on PE or PP. Eventually, a typically ceramic composite is applied to the separator with an engraving roller to meet the requirements of a lithium-ion battery. The PE-based wet process is the most widely used production method.
The methods to improve the electrochemical performance of lithium iron phosphate are presented in detail. 1. Introduction Battery technology is a core technology for all future generation clean energy vehicles such as fuel cell vehicles, electric vehicles and plug-in hybrid vehicles.
Despite significant progress in the field of ionic conductivity, the problem of Li dendrite formation and their penetration through “ceramic-in-polymer” electrolytes remains a major concern for solid-state batteries.
