RFP Title


Innovative Battery Technology
RFP Description


GS Yuasa International Ltd. R & D center (the Client), a major battery manufacturer, seeks a development partner for innovative battery technology. Specifically, any of the following A-D technical proposals are widely welcome: A) Lithium metal anode, B) Solid electrolyte (development or manufacturing technology), C) New high-capacity storage battery, D) New inexpensive battery with higher performance than lead-acid battery.

With a proven record in producing batteries for automobile, aviation, and space, the Client desires to promote the development of next-generation battery that exceeds the performance of lithium-ion (Li-ion) and lead-acid batteries, by combining their own resources, technologies, and know-how with advanced technology of other parties.

Key Success Criteria

Technological Requirements

Collaboration proposals (development or manufacturing partner) in areas that fall under any of A to D are welcome:

A)    Lithium metal anode

A development partner holding the following technologies is needed:

i.     Technology that can achieve a capacity retention rate of ≥80% in 2000 charge and discharge cycles in the future

ii.    The following technologies are targeted, for example, but not limited to:

(1)    Technology to restrain the growth of Li dendrites

(2)    Technology to make the most effective use of lithium anode by devising components such as separator, electrolyte (including polymer and inorganic/organic solid electrolytes), current collector, and anode structure

(3)    Self-healing polymer materials (preferable to have the following properties: Li ion conductivity, high Li ion transference number, electrolyte resistance, and oxidation / reduction resistance.)


B)    Solid electrolyte (for Li-ion and all-solid-state batteries)

A partner that fall under either of following i OR ii is needed:

i.     Development partner: Holding breakthrough technology for solid electrolytes (inorganic or organic, hybrid) used in Li-ion batteries
The following technologies are targeted, for example, but not limited to:

(1)    Technology that significantly reduces contact resistance at the interface between electrode active material and solid electrolyte

(2)    Technology that enable to handle sulfur-containing solid electrolyte in the air

ii.    Manufacturing technology partner: Capable of synthesizing a sulfide-based solid electrolyte (compound example: Li7P3S11) (Specific composition will be provided by the Client)

(1)    Production scale: more than tens of kg per month

(2)    Synthesis technique: Excellent mass productivity and quality. Note that the ball mill is undesirable because of low productivity and contamination problem.

(3)    Quality control: Capable of controlling at low humidity (dew point about −60°C) from synthesis to delivery

(4)    Desired performance: Excellent ion conductivity. ≥10-3 Scm-1 for general composition Li7P3S11


C)    New high-capacity secondary battery

A development partner with following technology is needed:

i.    Requirements: New secondary battery that can achieve the following conditions in the future:

(1)    Gravimetric energy density: ≥500 Wh/kg or volume energy density: ≥1000 Wh/L

(2)    ≥80% capacity retention after 200 cycles

ii.   The following technologies are of interest, for example, but not limited to:

(1)    Breakthrough technology for next-generation batteries such as metal-air battery (including lithium), lithium-sulfur battery, and sodium-sulfur battery

(2)    Batteries based on new principles other than those listed above


D)    New inexpensive batteries with higher performance than lead-acid batteries

A technology development partner that meets the following requirements is needed:

i.    Manufacturing cost that potentially becomes lower than lead-acid batteries in the future

ii.   No use of toxic metals such as lead, cadmium, mercury, and hexavalent chromium

iii.  Potentially capable of achieving a gravimetric energy density of 100 Wh/kg and volume energy density of 200 Wh/L in the future

iv.  The operating temperature range is as wide as from −30°C to 60°

Approaches not of Interest

Approaches Not of Interest

The following technologies are not of interest:

  • Technologies other than chemical batteries such as electric double layer capacitor
  • Battery technology that requires devices other than power storage elements such as redox flow
  • Fuel cell technology
Items to be Submitted


The Client, as a major manufacturer of lithium-ion (Li-ion) and lead-acid batteries, has an abundant track record in the automotive and aerospace fields. For example, the manufacturer received 2018 Best Supplier Award from Boeing. (*)

With the desire to promote the effective use of energy for the creation of a sustainable society, the Client has consistently promoted technology development.

In Li-ion batteries, higher energy density is required for spreading automotive use. Specifically, the development of technology to increase the capacity of Li-ion batteries or alternatively, new high capacity battery is aimed at.

Technology development efforts mentioned above are promoted by various organizations all over the world including the Client. The Client decided to seek proposals to accelerate technology development by collaborating with an external partner with superior expertise and knowledge.


Notes on Response

Proposal shall have clear points and should not include confidential information. Supplemental files may be submitted in addition to the proposal.


Response Evaluation

The client will evaluate all responses with the following criteria.

  • Overall scientific and technical merit
  • Approach to proof of concept or performance
  • Economic potential of concept
  • Realism of the proposed plan (action items, timeline, roles, deliverables, cost estimation)
  • Potential for proprietary position
  • Respondents’ capability and related experiences


Anticipated Project Process

After the submission due date, the client will review all submitted proposals. NineSigma will send the review results to each proposer 6-8 weeks after the due date. The client possibly asks clarifying questions before selecting the most suitable candidates for collaboration. The client will select best candidates through evaluations. During the selection process, the client may execute NDA with selected respondents, seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreements with the selected respondents and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.
