New work on fast-charging batteries has recently been reported by Zhang and colleagues. 93 This article focuses on the extremely fast charging of high energy LIBs by engineering the electrolyte to reduce the charge transfer energy barriers at both the anode and cathode.
Specifically, by integrating advanced algorithms such as adaptive control and predictive control, it is possible to accurately adjust the current changes during the charging process, ensuring that the current distribution and duration of each stage reach an optimized state, thereby improving charging efficiency and battery life.
In contrast to batteries, charge storage in supercapacitors is non-faradaic and occurs by the physical adsorption and desorption of ions inside the pores of the carbon electrodes when an external voltage is applied.
The application characteristics of batteries primarily include temperature, charging time, charging capacity, energy consumption, and efficiency. The MSCC charging strategy effectively prevents overheating of the battery during the charging process by controlling the charging current.
The most common DC fast charging (DCFC) posts can charge at a power of 50 kW using CHArge de MOve (CHAdeMO), Combined Charging System (CCS) or GB/T standard connectors. Tesla were the first to introduce 120 kW charging posts (Tesla Superchargers) equipped with custom connectors. CCS has since followed suit, developing 150 kW chargers.
