Toshiba making SCiB battery business an independent unit; higher energy density batteries with titanium niobium oxide anodes for EVs

Toshiba Corporation is taking its SCiB rechargeable battery business from Toshiba Infrastructure Systems & Solutions Corporation (TISS) to make it an independent business unit within Toshiba.

The reorganization advances the strategy of the Toshiba Next Plan, announced on 8 November, which positions the battery business as a new growth business. Positioning the business as an independent operation will remove layers of management and allow for more rapid decision making. TISS will continue to handle business operations related to using the SCiB as a storage battery system in sectors including rail transport, defense and power transmission substations.

Toshiba has manufactured and sold SCiB, the lithium-ion rechargeable battery that features high security, long life, low-temperature operation and rapid charging since March 2008. Its versatility has found broad application in hybrid electric vehicles, automated guided vehicles and energy storage systems for rolling stock.

SCiB rechargeable cells are categorized into two types: high power and high energy.

Now, by fully utilizing its technologies and development resources, Toshiba is advancing the development of higher energy density batteries with titanium niobium oxide anodes for use in electric vehicles. (Earlier post.)

SCiB currently uses lithium titanium oxide (LTO) in its anode to achieve excellent characteristics, including safety, long life, low-temperature performance, rapid charging, high input/output power and large effective capacity.

Demand for SCiB is growing, and Toshiba is expanding production capacity through capital investment and alliances. In Japan, the company will construct a new production facility in Yokohama, Kanagawa prefecture, and reinforce the current manufacturing facility, Kashiwazaki Operations in Niigata prefecture.

Separately, in 2017, Toshiba, Suzuki Motor Corporation and Denso Corporation agreed to establish a joint venture company to produce automotive lithium-ion battery packs in India, and Toshiba will also collaborate with Johnson Controls Power Solutions in the US.

Moving forward, and drawing on management expertise and know-how in mass production cultivated over the years, Toshiba will proactively channel resources into expanding the battery business. The company’s own wide ranging businesses allow promotion of opportunities beyond TISS’ scope of operations, with a focus on growth markets where SCiB’s characteristics can be used to the full.

By promoting expansion of business opportunities Toshiba aims for sales of ¥400 billion (US$3.6 billion) in 2030.

After 11+ years, this second generation very quick charge long lasting all weather SCiB battery is still looking for massive usage.

Are higher price and mid energy density the problems to be resolved?

This will work for buses and trucks, lots of electrification left to do.

With LG Chem pushing the Enevate chemistry, Toshiba may be relegated to the hybrid vehicle market, electric bicycles and power tools.  The silicon-dominant electrodes have much higher energy density and once there's enough battery capacity to support the required power output (~10 C or so) the advantage in size and weight favors Enevate over SCiB.

It seems as though the best to emerge on the market so far is the cell architecture and chemistry offered by Innolith. A innovative grid bank has been puttering on a US grid for ca. 2 years achieving unparalleled results.

Series production to start in 2019; mass production is scheduled for 2020.

From the Innolith article:

The company is now being rebooted this week under a new name, Innolith, and with a focus on R&D rather than battery manufacturing.

Innolith, which is registered in Basel, Switzerland, will look to license its technology to third-party manufacturers.

Looks like they're way behind Enevate.  Unless they've got a major advance in chemistry they have already lost this race.

@ EP
I think you missed the best points.
1) 50.000 cycles
2) negligible capacity losses during those cycles
3) non-flammable
4) absolutely no Cobalt
5) at least twice the energy density per unit of vol. / mass than SOA
6) fast charge and discharge
7) costs reduced to 1/3 or 1/10 of present cells SOA

SJC

Yes, these batteries have applications. There is always someone being negative and forcing their point of view on others.

Engineer-Poet

It still looks like Innolith is lacking a manufacturer.  Unless they hook up with someone like Union Carbide to mass-produce their materials they aren't able to go up against the Enevate/LG Chem/Reneault/Nissan/Mitsubishi alliance.

Innolith is a still Alevo. The same people are involved.

gryf

Alevo has a history.

It seems that members of this new JV have the financial capabilities to mass produce sell and/or use this second generation battery? Other interested parties could join the JV to expand the market.

More the better!
