Sakuu Announces 3D-Printed Solid-State Battery Success
Sakuu announced today that it has successfully 3D printed solid-state batteries in custom shapes that include cooling channels.
Sakuu Proprietary Solid-State Battery Factory
Sakuu has invented a fully industrialized process for printing batteries using a proprietary multi-material, multi-layer approach in a parallel and dry process instead of the much slower layer-on-layer printing or screen printing. Both of those are wet processes that require significant energy to remove unwanted solvents and are susceptible to poor printing quality and unreliable production.
The Sakuu invention can deliver low cost, high speed manufacturing capability coupled with flexibility in shape and form while also delivering batteries in core categories that matter most to clients and customers alike. For example, Sakuu’s first printed batteries have demonstrated successful cycling performance at C/5 IC current rates and the company fully expects to achieve high energy densities of 800 to 1000 Wh/L.
Utilizing proprietary lithium metal battery chemistry, Sakuu’s printing process starts with raw material and ends with a ready-to-use patterned battery, creating a new paradigm in manufacturing and energy storage. The achievement of patterned battery printing enables a more effective use of battery cell volume with new pathways in thermal dynamic regulation.
This allows integration of fixturing, sensors, and thermal transport pathways, as well as regulation through the patterned design, especially when thin sub-cell battery structures are stacked with identical patterned openings for thermal management in alignment.
“Collectively, our additive manufacturing and battery teams have accomplished what most thought impossible. Printing custom patterned batteries using a dry process that starts with raw material and concludes with a fully functional high-performance battery is a breakthrough that has the potential to transform how batteries of the future are manufactured for all industries,” said Robert Bagheri. “This milestone advances integration between our KavianTM platform and our commercial scale battery production plans towards an energy output goal of 200 GWh by 2030 via a network of global partner gigafactories.”
Sakuu’s Kavian platform will be sold to other battery manufacturers as well as leading automotive, e-mobility, and aerospace manufacturers. Those seeking to mass produce batteries can shorten their supply chains and gain key cell performance and safety attributes. Other inherent material and energy savings and sustainability benefits are realized by such maximum product design innovation.
In addition, Sakuu plans on licensing its own battery chemistries, both lithium-metal and solid-state, to be produced with either traditional roll-to-roll manufacturing or in gigafactories utilizing Kavian manufacturing techniques.
Sakuu says its pioneering manufacturing technology has created a disruptive additive manufacturing platform for commercial production of batteries and other complex active devices. Its non-battery manufacturing platforms are capable of producing medical devices, IoT sensors, and other cutting edge electrical devices and doing so in a highly sustainable and efficient manner, according to the company.
In its press release today, Sakuu says its initial efforts will focus on energy storage using its Kavian platform to print a range of next generation batteries — from lithium metal to all-solid-state — that can help reduce society’s reliance on fossil fuels.
According to 3D Printing Industry, “The company appears to be on the track it has planned out. With twice the energy density and 30% less weight than existing Li-ion cells, the firm’s second-gen batteries have potential residential and industrial applications within energy storage, micro-reactors and electronics.”
The Takeaway
There are many companies racing to bring solid-state batteries to market, including QuantumScape and StoreDot. One of the principal benefits of solid-state batteries is that they significantly reduce the need to remove liquids from the “wet” substrates used in conventional lithium-ion batteries — a process that takes a substantial amount of time to complete and consumes large quantities of energy to accomplish. Eliminating the wet slurry currently used in the “jelly roll” batteries of today will greatly speed up production times and lower battery unit costs.
There is no guarantee that Sakuu will win the solid-state battery sweepstakes, but it certainly has lofty ambitions. 200 GWh a year of batteries is enough to power millions of battery-electric cars and trucks. CATL, the world’s largest battery manufacturer today produced 97 GWh in 2021, almost a third of the worldwide total of 297 GWh. Even Sakuu’s more modest goal of 60 GWh by 2028 is quite ambitious.
It now has actual early production battery cells in the hands of potential customers in the automotive sector and other industries. We know our readers want to see technical data about how the Sakuu batteries perform, and we have reached out to Sakuu to see if they are willing to share that information with us. This is a very competitive industry that jealously guards its proprietary information. If we get any further information from the company, we will share it with our readers.

This! People don't seem to understand that many aspects of natural climate control are nearing tipping points and once that is reached scientists don't really know what can happen but none of it is good. Huge areas of permafrost that have stayed frozen for decades are thawing in the summer which releases mega-tonnes of CO2 and methane which is worse than CO2 by a factor of 27 I believe.some red meat for the thread.

I live at 56°N in Alberta and have since '01. Been on this acreage since '03 and the weather has changed a lot in just that 20 years. Mostly for the good for us as there's lot less snow every winter and isn't getting as cold as long as it used to either. Last Dec was weird tho as it was below -30C for most of the month and that kind of weather usually happens in Jan/Feb but this year it's been over 0C for more days than it's been below during the day with many nights not getting down to 0.
We used to have 8' drifts of snow in the back yard as the snow here is usually very dry and we get a lot of wind to pile it up. Right now we have maybe a foot of snow in the yard with no drifts as it's been warmer and the snow is wetter and sticks where it falls. Last year the fall lasted into Oct before we started to get any frost of note and has been getting longer for the last decade. The first winters we spent here we'd have a killing frost and or snow before the end of August. Extending mosquito season is what's happening tho they weren't bad last summer/fall as it was a lot drier than usual.
All the industrialized countries of the world that have caused this problem have been dragging their feet over doing anything about it and we're all going to pay one way or another. We got together on the ozone layer issue and that is slowly improving so why the hell can't we actually do it again!
Too many people but I'm thinking that problem is going to take care of itself.

It's all farm fields all the way up to High Level and beyond. A lot of canola and grain crops but nothing like orchards or stuff like corn or soy. I'm surrounded by those crops each season. The land up here was settled in the early 1900s and more is cleared every year for mostly GMO crops. Now we got hemp farms popping up so no outdoor pot growing for me. There is no ground water here so it's dugouts or hook up to town water that's not much better tho treated to make it potable and would cost me about 20G to hook up and a min of $60/mth for about 15 cubes and another $8/cubic meter over that and we'd need lots over to water the garden. My dugout is 80x50x4m deep so got lots of free water here but can't drink it until I get off my ass and hook up my RO system with UV sterilization. Bought all the stuff over a year ago but haven't got it done yet. Have not been well.
At least the air is fresh and clean with no large industries within 200km of us. Worst air pollution we get is smoke blowing over from BC forest fires and that's just a few days each year but getting worse every year. They'll run out of forests to burn soon so should get better instead of worse as time passes. Northern forests are slow growing and commercial forestry is shutting down at a rapid pace in northern BC as easy to log trees disappear.

i've thought about a series of satellites with "sails' that deploy when they're in place, that would do essentially the same thing on a slightly smaller scale...easy enough to keep them powered with a few solar arrays, easily replaced, relatively cheap...

imo that is the single good thing about LarStink - a coupla zillion reflectors.
The moon dust proposal has several problems, but the biggie is that the dust gets cleaned out quickly by sunlight pressure.

i have no idea of the mechanics involved, but isn't there a point where the loss of mass will effect the moons orbit? i'm assuming this wouldn't approach that point, but how long can this work for? it's only a delaying tactic...the real solution involves people doing what needs to be done.

To inject the gigatons of dust in question means accelerating them to lunar escape at 2.4 km/s. That requires a massive and expensive industrial base sucking down many gigawatts of power.
So, if we accept money as one of the physical quantities in the equation, the process is endonumismic*, consuming more money than it saves elsewhere. Cheaper to stop burning coal, just for starters.
