6 New Developments in Electric Vehicle Battery Technology


6 New Developments in Electric Vehicle Battery Technology, The new Developments in Electric Vehicle Battery Technologies are central to electric vehicles (EVs.) .These technologies have become more sophisticated in recent years, providing enhanced performance for electric vehicles. This  provide an overview of the latest developments in electric vehicle battery technology.

Electric Vehicles: Driving the Industry Toward an Emission-Free Future

6 New Developments in Electric Vehicle Battery Technology, Transportation is the second largest emitter of greenhouse gases behind the energy industry. Addressing this issue and reducing the industry’s impact on climate change is a central concern of researchers, industry bodies, and governments worldwide. In the past decade, the global electric vehicle market has taken a significant leap forward, with increased consumer demand for ultra-low emission vehicles driving the industry’s evolution. While the global COVID-19 pandemic disrupted the automobile industry somewhat, growth in EV sales has remained positive. Meeting global net-zero goals is a large part of this revolution in EVs, with many countries aiming to phase out the sale of new internal combustion engine (ICE) vehicles completely over the coming decades. However, key concerns remain with electric vehicles, such as range anxiety, battery performance, and sustainability.

Improving Battery Technologies

New Developments in Electric Vehicle Battery Technology. The race for improved EV batteries has been likened to a new gold rush. Developing battery technologies that give EVs better range, faster charging times, and enhanced performance, reliability, and safety is a central focus of research in the industry. Several exciting developments have been reported by researchers and automakers in the past few years, which will help the EV industry meet the demands and address the concerns of consumers. While many challenges still lie ahead, driving the transportation sector toward a post-carbon model is essential.

A Game-Changing Fast-Charging Hybrid EV Battery

New Developments in Electric Vehicle Battery Technology, One of the chief concerns which currently hinders widespread consumer adoption of EV technologies is their charging time. While progress has been made in reducing charging times from the several hours that EVs have required until recently, current commercially available models cannot compete with ICE vehicles in this respect. Charging a battery in less time than it takes to refuel an ICE vehicle would be a game-changing development in battery technology that could significantly increase the consumer uptake of these vehicles. It has revealed an innovative battery technology that reduces the charging time for EVs to around 72 seconds. The company’s innovative EV battery is a hybrid system that utilizes both conventional battery and ultracapacitor technologies.

Improving the Safety of Lithium-ion Batteries

Safety is a chief concern for EV battery manufacturers. While rare, lithium-ion batteries can catch fire, especially if damaged. Every year, companies spend vast amounts of money on developing and testing safer batteries that do not run the risk of fire. Researchers at Stanford University have developed an electrolyte that is fire-proof even at extreme temperatures of over 140F. Central to this solution is extra lithium salt in the electrolytes. The team added lithium salt (specifically LiFSI) to a polymer-based electrolyte. The lithium salt content of the electrolyte was increased from less than half to 63% by weight. Effectively, LiFSI acts as an “anchor” in the electrolyte for highly-flammable solvent molecules. Through this innovative solution, lithium-ion batteries can continue to operate at temperatures as high as 212F.

Revealing Elusive Interphase Chemistry with X-rays

Scientists from the US Department of Energy have provided new insights into interphase chemistry. The interphase in a battery is crucial for improving energy density. The interphase forms between the electrolyte and anode as the battery undergoes charge and discharge cycles. The researchers published an in-depth study in Nature Nanotechnology on the solid-electrolyte interphase in lithium-ion batteries and unveiled its convoluted chemistry. The researcher’s approach leveraged the X-Ray Powder Diffraction beamline at the National Synchrotron Light Source II. The team’s innovative approach leveraged a unique combination of advanced X-Ray techniques to provide an unprecedented detailed chemical map of interphase components. The research revealed intimate details of interphase chemistry, which will help future scientists design improved interphases in lithium metal batteries.

Other New Developments

Scientists have explored multiple research angles to improve battery design and associated technological elements of EVs in the past few years, providing innovative solutions for several key challenges within the industry. NAWA technologies have designed a revolutionary ultra-fast carbon nanotube electrode that significantly boosts battery power, energy storage, and lifecycle. Researchers at Chalmers University of Technology have focused on incorporating batteries as structural elements, which could reduce the weight of EVs. The University of Texas has explored cobalt-free batteries, which overcome resource scarcity issues of this critical metal. Researchers in Finland have developed silicon anode batteries. IBM is working with Mercedes-Benz to develop batteries with materials extracted from seawater.
