Evolution of electric vehicle battery technologies

Overview

Developments in battery technology are focusing on reducing lithium dependency and improving safety and longevity through various chemical and material innovations. Initial efforts highlight the transition toward sodium-ion batteries for urban and commercial use, as well as the pursuit of solid-state batteries to replace flammable liquid electrolytes with solid materials. While lithium-ion remains the market standard, these alternatives aim to address energy density and manufacturing scalability.

Recent research has introduced specific methods to enhance existing and emerging technologies, such as using xenon difluoride to stabilize nickel-rich layered oxides and developing zinc-iodine batteries with starch-derived polymers to mitigate the ‘shuttle effect’. To address mineral scarcity and cost volatility, researchers are diversifying chemistries. A joint team from Japan and the United States has designed a tunnel-structured molybdenum oxide electrode to improve calcium and magnesium batteries, limiting lattice expansion to less than 2% to minimize mechanical stress during cycles. Additionally, engineers at the Southwest Research Institute have introduced the Electrical Interchangeability Index to help determine if lower-cost sodium-ion batteries can replace lithium-ion in specific applications.

Newer investigations are targeting structural optimizations. A research team led by Professor Kyojin Ku at Hanbat National University in Korea has found that intentionally introducing cation disorder into the atomic structure of lithium-rich cathodes can enhance lithium movement and prevent performance degradation. Meanwhile, sodium continues to emerge as a cost-effective alternative; while currently heavier than lithium-based counterparts, sodium batteries offer advantages including faster charge and discharge capabilities, greater intrinsic safety, and a wider operating temperature range.
