Enevate Battery Start-Up Secures Funding From LG Chem

OCT 24 2018 BY MARK KANE 18

LG Chem invested in Enevate in its search for next-gen tech.

Enevate Corporation, a battery start-up which develops silicon-dominant composite anode materials, attracted LG Chem among other investors in the recent funding round.

Details of the transaction or partnership were not announced, but it seems that the South Korean manufacturer had an eye on the progress at Enevate.

Enevate HD-Energy Technology

“This investment is a nod to the viability of Enevate’s technology which could enable Electric Vehicles (EVs) to charge in the same time as gas cars without compromise.”

Enevate promises that its cells are ready for ultra-fast charging in 5-minutes and at the same time store more energy per unit of weight than state-of-the-art commercial lithium-ion cells.

Enevate highlights:

  • batteries to be charged to 75% capacity in five minutes
  • higher energy densities than available for today’s current long-range EVs
  • can also safely charge and discharge down to -40°C and capture more energy during regenerative braking

Robert A. Rango, Enevate’s President and CEO said:

“The strategic investment from LG Chem indicates the significance of our technology because it could directly address consumer concerns with EVs, such as charge time and range anxiety, cost, and safety. We look forward to our strategic partnerships with companies such as LG Chem to commercialize advanced batteries that will accelerate the adoption of EVs worldwide.”

uhhhhh…………..good luck?

I’m sure LG Chem, which has quite a bit of experience with Li-ion batteries, would not randomly throw money at startups.
I’ll remain hopefully optimistic.

I Hope All this Is True ,Legit & Real !!!

I’m not optimistic about this one. They spun out of University of California in 2005. $5m initial funding, then 24m in 2012 and finally an oddball 30m round in 2015 led by one of Blackberry’s founders.

They’ve won innovation awards over the years, but no customers. No spec sheets on their web site. They first claimed 75% charge in 5 minutes a year ago (10C rate), but their web site shows 90% in 15 minutes (~4C). Years ago they talked about real markets like rugged smart phones and such. Now they talk about EVs, which is just hype as no new technology can hit EV price points until years of scaling up.

They give no numbers on LG’s investment, always a red flag. My guess it’s just enough to keep Enevate alive while they go in and see if there’s anything worth saving.

If it can easily be integrated in existing production facilities, no scaling is needed…

Doggydogworld

If it was that easy to integrate someone would have dedicated an old line to it and built a bunch of cells for niche markets already.

Even minor chemistry tweaks (e.g. NMC622 to NMC811) take many years to scale up. The new cells start out expensive because supply is limited and there’s always some niche market willing to pay extra for improved performance. It takes 3-5 years to prove the new chemistry in the field, optimize the chemistry and manufacturing process, ramp volumes up and ride the cost curve down. The more radical the change, the longer it takes.

Now, how about they send a few samples to Tesla…
I am sure, if they have something worth funding, Tesla will be quite happy to not only fund said battery, but also become a customer….

Elemental

Sure but how long will they last with consistent charge rates like that? I’m fairly certain you can do 75% charging on many battery types these days, but they probably wont last for many cycles. This is already improving year on year, so I’m quite sure we will see 5 minute charge times at some point in the not too distant future. Until I see it though, with long term cycle guarantees, I’ll remain skeptical of these startup companies.

Titanate can charge fast and do that for over 5000 cycles.
That is a unique anode, these are silicon anodes, we will see.

antrik

5,000 cycles is pretty much the lower bound for LTO… Some variants claim 20,000.

Silicon is very different, though. Indeed cycle stability is the one and only reason why silicon-dominant anodes haven’t made it out of niche uses thus far.

antrik

They claim the silicon anodes prevent lithium plating, which is the major limiting factor for faster charging of traditional Li-Ion cells. So the fast charging should presumably not come at the expense of cycle life…

The problem with silicon anodes however is that they usually have very poor cycle stability to begin with (because of mechanical degradation due to volume expansion) — regardless of charging speed… If they indeed found a viable way to fix the mechanical issue, fast charging shouldn’t be a problem.

There was something I have been noticing lately in trying to find the prefect back up battery system for my fish tank system.

What I notice is that large lead acid batteries are still used in a lot of things like home appliance back up battery systems.

earl colby pottinger

That is because Lead-Acid is still cheaper than Lithium-Ion on kWh per dollar.

Also, if you make a trickle charger that does not turn off when the batteries is full, with Lead-Acid you tend to just boil off some water, with Lithium-Ion you can damage the batteries.

Lead-Acid can use cheap electronics for charging, Lithium-Ion needs a proper BMS if it is going to be left unattended for long periods.

antrik

Li-Ion *always* needs a proper BMS.

TomN

It must be battery cost, not the battery management system, because now days the electronics for a computerized BMS is also very cheap.

Cost?

Richard Giddens

Thermal issues? No meltdowns, shorts or explosions, right?

earl colby pottinger

For Lead-Acid you do need proper venting of the hydrogen or sealed batteries to avoided any fire/explosion.
