Japan Backs Solid-State Battery Efforts With $90 Million In Funds


JUN 18 2018 BY MARK KANE 11

Japan’s New Energy and Industrial Technology Development Organization (NEDO) is trying to leverage research on solid-state batteries for electric cars.

The organization allocates 10 ¥10-billion ($90 million) for the research to be conducted by 23 automobile, battery, and material manufacturers as well as 15 universities / public research institutes. Participants includes Toyota, Nissan, Honda, Panasonic and more…

The government hopes that the technology will be ready by fiscal year 2022. The target price on the pack level for EV batteries was set at $90/kWh by 2030 (a third of the current value, according to the report). Another target is a 10-minute recharge.

“The project… will tackle technologies that are currently bottlenecks for mass production of solid-state Li-ion batteries (SSLIB) such as the solid electrolyte; electrolyte coating with active material, and the sheet formation of the electrolyte-electrode layer.

In addition, the project will develop simulation technology to predict the deterioration of all-solid LIB cells and battery packs, and test evaluation methods for durability and safety with international standardization.”

At a press conference, Yoshiteru Sato, an executive director of NEDO, warned that while Japan “has a big lead” in developing the all solid-state battery, which uses solid substances instead of an electrolytic solution, research in other countries is advancing as well.

Previously, Japanese industry started cooperation on solid-state batteries around Lithium Ion Battery Technology and Evaluation Center (Libtec).

Partners participating in this project include:

  • Toyota Motor Corporation
  • Nissan Motor Co., Ltd.
  • Honda R & D Laboratories
  • Panasonic Corporation
  • GS Yuasa Corporation
  • Hitachi Automotive Systems Co., Ltd.
  • Maxell Corporation
  • Murata Manufacturing Co., Ltd.
  • Yamaha Mr. Motor Co., Ltd.
  • Asahi Kasei Corporation
  • JSR Corporation
  • Sumitomo Metal Mining Co., Ltd.
  • Dai Nippon Printing Co., Ltd.
  • Toppan Printing Co., Ltd.
  • Toray Industries, Ltd.
  • Nippon Shokubai
  • Fujifilm Corporation
  • Mitsui Chemicals Corporation
  • Mitsubishi Chemical Corporation
  • Kuraray Co., Ltd.
  • Nissan Chemical Industries Ltd.
  • Idemitsu Kosan Co., Ltd.
  • Mitsui Mining and Smelting Co.
  • National Institute of Advanced Industrial Science and Technology
  • National Institute for Materials Science
  • National Institute of Physical and Chemical Research (RIKEN)
  • Osaka Industrial Technology Research Institute,
  • Kyushu University; Kyoto University
  • Gunma University; Tokyo Institute of Technology
  • Toyohashi University of Technology
  • Nagoya University

“The target price on the pack level for EV batteries was set at $90/kWh by 2030” – I thought Tesla would get there 2020 with current battery tec. If so, good luck to those companies waiting for solid state batteries.

Actually Musk has said that he is confident that they get below $100/kWh on the pack level within 2-3 years.

There are many benefits if they get this thing done, not just the price.

Nature article number: 16030 published in 2016:
– Greater power density – stable cycling at 18C (rapid charging)
– Superior performance compared with the lithium-ion cells between −30 and 100°C. (No active thermal management necessary)
– Superior safety
– Greater energy density (volume), but not so much Specific energy (mass)

In the end it will all come down to mass production and materials used, we will have to see how this pans out, but the potential is huge.

I don’t see how they can move away from a thermal management system.

No matter how you make the batteries they will heat up as current flows thru them, and without a way to get rid of that heat when doing long runs 4-5 hours on the highway they will result in some very hot batteries.

Earl, the heat is caused by the resistance of the liquid electrolytes as the energy flows in. Solid state reduces that resistance immensely.

Lithiums inventor Dr Goodenough has his own solid state battery in commercialization. Sodium Glass. 10x the lifespand, 3x the energy density. 1/10th the cost. No precious metals. While industry was skeptical of his claims German engineers have now successfully produced the first test cells using this chemistry in standard 18650 cell form. Even in the first attempt they saw a 6x increase in longevity and 120% increase in capacity over Lithium Ion. Further development will produce better results.

I think they car confusing advancement with economy of scale. If Tesla builds 3 or 4 gigafactories and sells 1M+ vehicles per year, they will hit $90/kWh no problem with current technology. The Japanese are waiting for this magical solid state battery before they can go into the EV market… the ship has already left the port. Current technology is good enough.. you just need to build more and more batteries.

The country with the manufacturer with the highest EV sales globally isn’t in the EV market??? That’s some pretty high entry requirements!

It’s just nice to see that much effort invested.

I agree. With the effort being poured into battery research I am convinced a breakthrough will come. It is just a matter of time.

Solid electrolyte is important, glad they are working together.
