German Scientists Develop Lithium-Ion Battery That Lasts for 27 Years


27 years sure is a long time, isn’t it?  Would we even desire a lithium-ion battery that lasts that long? Probably not, considering automobiles don’t fare too well, in general, as they age.

Regardless of whether we want it or not, a group of German scientists claim to have developed the 27-year lithium-ion battery.  Technically, it’s life is listed at 10,000 cycles, but 27 years sounds more flashy to us.

Scientists from the Center for Solar Energy and Hydrogen Research Baden-Wurttemburg (ZSW) in Germany developed a potential breakthrough battery than retains up to 85% capacity after 27 years of daily use.

The scientists says the battery boasts high energy density and can charge quickly.  This breakthrough battery—which we know very little about due to the secretive nature of these scientists and their inability to write in common English—displays incredible stability, while easily lasting for more than 10,000 discharge/charge cycles.

Energy density is claimed to be in the range of 1,100 W/kg, a spectacular figure indeed.

The breakthrough batteries are currenly being produced in small samples so that they can be further tested and refined prior to kicking up production for commercialization.

Eventually, the scientists see these batteries as being manufactured in large pouch cells and large prismatic cells for use in future electric vehicles

I was hoping it could happen – the electric car has finally arrived!!!!!!!!!! ;>)

If I had a nickle….

Sorry to bust your bubble, but the they are talking about its power density, not its energy density. Typically, improving one, comes at the expense of the other. They can fast charge and fast discharge, every time for decades because of the huge power density. The energy density is in line with what we are used to. This means smaller, more aerodynamic vehicles are still the best way to go. But they would be very cheap to operate, in money and CO2 for your lifetime. Don’t know what kind of business model you can make for something as amazing as that though.

The unit used here was already power density (W/kg), so you could realise some error without the press release.
Where did you find any information on the energy density though? I could not, so for now I’m going to assume that it is not too great and thus this could be great for (grid) storage uses in case the costs are reasonable, but now for EVs. To me energy density seems most important for EVs for the time beeing.

Can’t find it now. But it was supposedly a quote from one of their people saying that they fell within the current range of lithium cells for energy density, about 110-170 Wh/kg. He also said they had about half the voltage range of current cells.

That alone means a lot more cells, and a lot more connections, not good for weight.

Grid storage/solar backup is the business model for these batteries. The trick will be seeing what the energy density is – if its at or below 100Wh/kg, you’ll need a lot of physical space to store enough energy to balance out your solar loads. If they can get it higher to match today’s top of the line Li-Ion batteries (~200Wh/kg) then it becomes a lot more economical to backup your solar with batteries.

Anthony, energy density for solar storage is entirely irrelevant. 100 is plenty.
The issue there is $/total kWh throughput.

Whether your house pack weighs 50kg or 100kg is quite irrelevant. It’s the usage price that matters.

but for cars the weight really matters. and since these douches failed to include relevant data such as voltage and Wh/kg it’s likely that these batteries are just the more or less useless altair nano lithium titanate chemistry which long ago demonstrated such long cycle life.
that chemistry is typically around 60Wh/kg although toshiba recently claimed reaching 90Wh/kg which is almost good enough

Picture of clean-box with gloves inverted outward is hilarious.

If I were in that lab, I’m not sure if I would shake each one of those hands, or run down the line, giving them all high-5s! 😉

Now the only things we have to hope for are
– The claims turn out to be true
– These batteries don’t cost more than ‘regular’ li-ion batteries
– They are brought to market sooner rather than later
