NEC Energy to use 24M semi-solid Li-ion batteries in its grid storage systems

Battery start-up 24M and NEC Energy Solutions, Inc. have signed a Memorandum of Understanding (MoU) whereby 24M has agreed to supply its semi-solid lithium-ion cells (earlier post) for use in NEC Energy Solutions’ integrated storage systems. In addition, the companies will work together to ensure that supplied 24M cells enhance NEC system energy density, life and cost.

24M leverages existing, preferred energy storage chemistries but uses a new cell design with semi-solid (a mixture of solid and liquid phases) thick electrodes and manufacturing innovations to deliver what it says will be up to a 50% reduction in current Li-ion costs. (Co-founder and Chief Scientist Dr. Yet-Ming Chiang was also a co-founder of A123 Systems; 24M originated as an A123 spinout.)

NEC Energy Solutions combines ESS and intelligent controls to deliver innovative, tailored, technology solutions for electric grid, backup power and lead-acid replacement applications. The company also provides system integration expertise focusing on high performance, efficiency, safety and reliability.

Working together, NEC Energy Solutions and 24M will provide customers with high performance, 20-year battery life for reliable grid, off-grid and behind-the-meter solutions.

—Bud Collins, CEO of NEC Energy Solutions, Inc.

With a 50% reduction in cost and a 20+ years battery life it could be a good battery pack for extended range heavy vehicles, if it can be adapted?

A 20 year life cycle is great for grid storage, but not useful for EVs and electronics. The battery shouldn't outlive the device its in.

A 50% reduction in price for grid storage (down to $100-125/kWh) is a big win though, combined with a 20 year life cycle, that brings down the cost to about 2c/kWh which is about the price difference between peak and off-peak.

Future EVs will last 20+ years in many places.

My wife's previous Camry (made in Japan) lasted 20 years without rust and in VG conditions after 280,000+ Km.

Got a 16 year old 2000 Tacoma that's doing fine along with a 2011 Leaf that's been waiting for Nissan to develop a battery with some range.

Anthony:
This ain't your fathers VW diesel. EVs should run longer if for no other reason their simple drivelines have a lot fewer mechanical wear parts and they have no emissions or exhaust systems. also, Lithium batteries are useful electricity buffering device long after their service as traction batteries.

This is about the worst time imaginable to buy a car with a view to keeping it 20 years.

Whether largely autonomous driving takes 5 years or 10, it is coming, and the far better safety that will allow will make old cars insurance increase greatly, or uninsurable.

Apart from anything else, autonomous connected vehicles could safely travel at speed with far lower gaps than anything humans can manage, so piloting one would be a a very frightening experience.
