Electric vehicles [EV] of any type, from compact to luxury models, have one thing in common, and it’s their biggest problem. Researchers are discovering that they don’t know as much about lithium-ion [Li-ion] rechargeable battery packs as they thought they did, “so engineers overcompensate by building batteries that are too large,” said Miroslav Krstic, a faculty member of the Department of Mechanical and Aerospace Engineering at the Jacobs School of Engineering.
By experimenting with different materials and different charging controls, a couple of different research teams have been working in opposite directions for the same goal.
NEC Corp recently announced that it was able to build a new rechargeable Li-ion cell with 30% more energy density.
UC President’s Postdoctoral Fellow Scott Moura, the co-lead researcher on the project, and Krstic are working on sophisticated algorithms that predict what is going on at the molecular level while cycling, that is, discharging and recharging the battery pack. Krystic and Moura are hoping that their new methods will enable better management of current Li-ion technology, making it possible to work closer to the thresholds of performance. Currently, hybrid electric vehicle [HEV] batteries, and probably EV batteries, only run a cycle between 20% and 80% charge, to prevent damage and maximize lifespan. Toyota just scrapped its second EV, the eQ, before it even launched, citing range and charging issues, but maybe it didn’t have to be so. Maybe the Nissan Leaf could use a 5%-95% cycle run by UCSD’s algorithms, and use 95% of its battery capacity of the improved NEC type.
The thirty-minute talk time of the old brick phone has given way to mobile phones with days of talk time.
Where I come from, most enthusiasts recognize the amazing engineering (particularly the engines). 2012 Mitsubishi i electric car battery packEnlarge PhotoWe'd be the first to point out that many of the electric car owners currently out on the roads have had absolutely no trouble with the 100 or so miles they get from a full charge.
However, it'd be foolish to assume that some people really don't need more than that, and as a result there's always room for an EV with greater range. Improvements to battery technology could be the best way to find this range, and according to New Scientist (via Autoblog), developments in Lithium-Air batteries from IBM could give us electric cars with a 500-mile range. Lithium-air batteries have significantly greater energy density than regular lithium-ion batteries - close to that of gasoline, in fact.
Several companies are working to improve Lithium-air technology, by testing moisture-proof battery membranes, and graphene cathodes. IBM is seeking to improve the electrolyte, the solvent that carries lithium ions between anode and cathode.


However, an IBM-led coalition called Battery 500, hopes to have a full-scale prototype running by 2013, and commercial batteries ready by 2020. You might have to wait a few more years for an electric car that truly goes further than the gasoline equivalent, but it's on its way. Lithium-ion battery pack for 2014 Chevrolet Spark EV electric carEnlarge PhotoIf it wasn't so important for the future of electric cars, it could almost get tiresome: Just how do you improve batteries for longer life, quicker charging and a greater range? It's a question being investigated by great minds all around the world, and has turned up some surprising and exciting results over the last few years. Inspired by Popular Mechanics' look at potential electric vehicle and hybrid battery breakthroughs, we've compiled many of our previous battery tech articles into one handy guide.
The aluminum plates used have high energy density, and companies testing it such as Phinergy say you'd need to refill the car with water every few hundred miles. Existing lithium-ion technology is among the best battery technology we have for electric cars and hybrids. Compared to other battery types it's relatively energy-dense, charges relatively quickly, is lighter than many other battery types, and it's tried-and-tested.
Others have researched into the existing problems with lithium-ion tech--such as reducing the tendency for lithium to gather around the battery electrodes. Then there's lithium-air tech--an offshoot of lithium-ion batteries, and one that could significantly increase energy density. It sounds unlikely, but simple herbs could be employed to make batteries greener in future. In a rare look at improving the environmental aspects of batteries rather than increasing their range, researchers at Rice University and the City College of New York have looked at using the herb madder, or purpurin, as a natural cathode for lithium-ion batteries. You might not gain hundreds of miles, but any eco-minded electric car driver would be glad to know their batteries had just a little less impact on the environment, right?

The battery pack in an EV is an engineering headache, a marketing nightmare, and could be the main reason that EVs haven’t gone mainstream yet. Engineers still have a lot to learn about exactly how Li-ion batteries function on a molecular scale.


The current methods of battery health estimation using voltage and current are not good enough to use the battery pack to its full potential. The first and last 20% are just not available for use, so in reality, the battery is 40% larger than it really needs to be. This would calculate to a range 142 miles, nearly double Nissan Leaf’s stock range of 73 miles. The electric car doesn’t have to stay dead for long, if the same kind of technological advancements make it into their design. That's enough to beat many internal combustion cars on sale today, and would certainly eliminate range anxiety. That means batteries could be down-scaled - and therefore vehicle weight reduced - while still increasing range. Current electrolytes react with air and become depleted over time, so IBM is testing various materials.
Aluminum is used as the anode in a battery, ambient air (and the oxygen in it) as a cathode, and water molecules. But it isn't perfect, and several research groups are looking for a way to improve on its existing strengths.
Researchers at University of California San Diego [UCSD] are developing new algorithms to control Li-ion batteries. The polycarbonate-based electrolyte was also upgraded to combat the oxidation caused by the higher voltage. Combined in the battery, they produce hydrated aluminum oxide and energy--and that energy can be used to power a car. Egg-line nanoparticles of sulfur are one option, improving energy transfer and hugely increasing capacity, while silicon nanoparticles to replace graphite anodes is another.
