24M & NEC Energy Solutions Ink MOU On Supplying Semisolid Lithium-ion Cells

October 15th, 2015 by  

A memorandum of understanding has been signed by 24M and NEC Energy Solutions whereby 24M has agreed to supply its semisolid lithium-ion cells for use in NEC Energy Solutions’ integrated storage systems.

The companies will also work together “to ensure that supplied 24M cells enhance NEC system energy density, life and cost.”

Sounds like a winning storage situation for both companies.

About 24M Batteries

These batteries are different from traditional lithium-ion batteries. Here’s why, according to 24M themselves:

“24M battery cells are optimized to withstand the rigors of the long cycle and calendar life required by grid-scale energy storage and other high-performance applications.”

They also combine superior design with manufacturing innovations to lower the total cost of ownership of a battery cell to just pennies per kWh, providing a rate of return equivalent to conventional fuel solutions.

In a press announcement, NEC Energy Solutions CEO Bud Collins stated that he believes combining 24M cells with its storage systems will provide customers with the most affordable energy storage systems. “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,” he said. “We look forward to incorporating these breakthrough batteries into our best-in-class ESS deployments across the globe.”

NEC Energy Solutions combines ESS and intelligent controls to deliver tailored technology solutions for electricity grid, backup power, and lead-acid replacement applications.

Throop Wilder, 24M CEO, provided his perspective on this agreement: “Through this MoU, NEC Energy Solutions and 24M will be able to bring industry-leading solutions to market more quickly and cost effectively, accelerating the adoption of advanced ESS across the globe.”

    The different solid Lithium I read on were all looking at entering the consumer electronics first. The at some later time move into bigger (EV and stationary). Looking at web site can’t tell that much, for sure no price information.

    TCOE of battery cell = “Pennies per Kwh”?

    That sounds good – I’ll have a 20kwh battery system please!

    • Calamity_Jean

      After you get yours, I want one.

      • mike_dyke

        “Buy one – get one free” at that price?

        • Calamity_Jean

          HA! Don’t count on it.

          At “pennies per kWh”, I’d be happy to pay full price.

          • mike_dyke

            And here was I going to pass on one to you since you asked nicely… Ah well…

            I’d also be happy to pay full price at that price.

            I wonder how long it will be before battery systems get down to that price? 20 years? 10 years? 5 years? 🙂

          • Calamity_Jean

            I’m guessing more than five years but less than ten.

      That is pennies per kWh delivered. Consider a 10 kWh battery that costs $1000 but can be cycled 5000 times. It costs $1000/10kWh = $100 per kWh of storage, but only $1000/10kWh/5000 = $0.02 per kWh delivered before the battery is dead.

    Does anyone know if there is any pilot plant or demonstration plant in use at a customer site, preferly > 1MW – MW/h?
