Recent advancement in rechargeable battery technologies

The ongoing energy issues worldwide have led to the continuous growth of the electrochemical energy storage system in recent years, and the battery is a vital part of it. The battery market, mainly rechargeable batteries, is expanding rapidly to cater to the demands of the changing society, along with the utilization of batteries in electric vehicles, the renewable energy sector, and the industrial sector. From the matured technology like the lead–acid battery to the most advanced Li‐ion (Li‐ion) battery, rechargeable battery technology has developed significantly. In comparison to the conventional lead–acid battery, other rechargeable battery technologies such as Li‐ion, nickel–metal hydride (NiMH), and nickel–cadmium (Ni–Cd) batteries are considered as more promising electrochemical energy storage systems. The Li‐ion battery, which has been on the market since 1991, is the most popular rechargeable battery due to its high energy density and good durability. With the growing market demand of battery with superior electrochemical performance in terms of specific energy, cyclability, stability, and better safety, next generation Li‐ion batteries are being widely explored in the recent time. This review discusses various rechargeable batteries which are in trend and the issues and challenges associated with it. The advancements that have taken place primarily in the electrode (both cathode and anode) materials, along with electrolytes, for improving the battery performance from the year 2000 onwards are discussed. Moreover, discussion on next‐generation batteries is also covered in this review.
