Kyocera launches residential energy storage system built using 24M’s semisolid lithium-ion battery process

Kyocera Corporation and 24M announced that Kyocera has formally launched its residential energy storage system, Enerezza, the first system built using 24M’s novel SemiSolid electrode manufacturing process. In addition, Kyocera has extended its commitment to 24M’s unique manufacturing platform with plans to start full-scale mass production in the fall of 2020.

In June 2019, Kyocera began pilot production of 24M’s SemiSolid battery technology to validate its use in residential energy storage systems in the Japanese market. Based on the successful pilot, Kyocera recently rolled out its full Enerezza product line—a 24M-based residential energy storage system available in 5.0 kWh, 10.0 kWh, and 15.0 kWh capacities designed to meet diverse customer needs.

24M’s innovative manufacturing process delivers market-leading price-performance. SemiSolid electrodes use no binder, mixing electrolyte with active materials to form a clay-like slurry with unique attributes. As a result, the 24M process eliminates the need for a significant amount of inactive materials and capital-intensive processes like drying and electrolyte filling, thus dramatically reducing manufacturing cost.

This is the first production battery using the 24M SemiSolid electrode manufacturing process. Could this be the "mysterious" Nikola Motors breakthrough battery as some have suggested?
. . .
Recently, NBC News reported that" the technology is a refinement of the current lithium-ion standard, rather than a complete replacement of it. The new method seems to involve “removing the binder material and electric current collectors used in today’s lithium-ion cells.” Will Nikola Motors buy 24M?
. . .
According to 24M if an appropriate Silicon Anode and Dual Electrolyte System are used this battery can reach almost 500 Wh/kg. We will just have to wait and see.

“this battery can reach almost 500 Wh/kg”

Is that what they are piloting or is that theoretical?
They don’t appear to have quantified any of their purported benefits and gravimetric density wasn’t even listed.

Nothing is in this Press Release. You must go to the 24M website Newsroom: Kyocera to Roll Out New Li-ion Battery in 2020, page 4. There is a chart that shows "The roadmap to the increase of the new battery's capacity density. It is scheduled to realize an energy density of about 500 Wh/kg in 2022." This is with Li/Si +DES for EV.
More than likely the Kyocera first application uses LFP not NMC cathodes and would not reach close to 500 Wh/kg. Nikola Motors claims their breakthrough reaches the 500 Wh/kg level. This will also require above average Silicon Anodes that are described in recent 2018/2019 research.

This article linked on the 24M website from May 2019 gives a pretty decent overview of the technology:

They claim there 350Wh/kg there as achieved.
