Samsung Invests In Lithium Polymer Battery Developer Seeo – Target Is 400 Wh/kg

JAN 2 2015 BY MARK KANE 11

Seeo, a company developing new generation lithium polymer batteries, announced that it closed its largest-to-date funding round of $17 million.

Among the investors appearing is Samsung Ventures Investment Corporation, which is the venture arm of Samsung.  Since Samsung already is in the lithium-ion battery business, Seeo’s developments must show some potential.

Hal Zarem, President and CEO of Seeo state:

“We appreciate the confidence Samsung Ventures has expressed in our technology and team with this investment. Samsung Ventures is a sophisticated investor with deep experience and a track-record of success in the space. Their engagement with Seeo will strengthen our ability to deliver the next generation of advanced batteries to a market eager for breakthrough capabilities.”

Seeo itself set a target of 400 Wh/kg on the cell level and, taking into consideration that 350 Wh/kg was already achieved by Seeo, the battery maker is close to hitting its target.

Here is the description of Seeo’s DryLyte – solid polymer electrolyte:

Seeo DryLyte™ Advanced Lithium Polymer Batteries

Seeo’s DryLyte electrolyte enables breakthroughs in energy density, which is a key enabler to increasing the range of electric vehicles (EVs). Currently, Seeo has cells cycling with an energy density of 350 Wh/kg, with a future target of 400 Wh/kg, roughly twice the level of batteries used in today’s EVs.

Seeo enables the production of safer batteries by replacing the flammable liquid electrolytes of conventional lithium-ion cells with Seeo’s DryLyte solid polymer electrolyte that is non-flammable and non-volatile. These enhanced safety characteristics, combined with exceptionally high energy density, represent a breakthrough for next-generation battery applications.”

Very encouraging news!

I just hope this kind of technology will be affordable for the masses soon.

I see they are not promoting their power rating (W/kg) or cost. They may not be suitable for cars at this time.

I guess the idea is, please wait just a few more years to buy an EV, while we get this super duper new battery working… And also wait for hydrogen fuel cells to be perfected. Please please wait till 2020.

Meanwhile, please go ahead and lease another ICE because look how cheap gas is – What happy days!!! Cheap financing and cheap gas – forever!!!

Take a 3 year lease.

Battery with 330 wh/kg are already available.price is around 400 Usd for 1Kw/h.
3000 cycle life. No need wait . Delivery in two weeks.

From Seeo, or someone else?

Pls send me info re 350wh kg battery

Love to see what cheap gas not an obstacle for battery tech industry!

P.S. gas prices dropped from 1.45 to 1.16 in Cyprus

Anyone with a half-decent ability to forecast can see that these low gas prices are temporary thing. With the low prices, the drilling in expensive oil plays (like fracking & tar sands) will stop, the glut will go away, and the prices will go back up. Perhaps not up to the >$100/barrel levels initially but they’ll eventually go back there.

Who knows if this one will be great but the big thing is that you now see all the auto companies investing big into batteries because they now realize that electrified automobiles (both PHEV and pure EV) are the future.

So, let me see here: current reliable mileage of my 2011 Leaf is about 60 miles with a battery density of about 150 Wh/Kg: At a density of about 400 Wh/Kg that would be 400/150 x 60 = about 150 miles.

I’ll be the first in line if it would fit the car and If the price is right.
