Background/Description

Lithium-ion batteries are used in an ever-increasing range of applications from consumer devices to electric cars, with research focusing until now on innovations around the cathode, anode and electrolyte materials used. As the rate of improvement in energy density begins to slow from these innovations, many research efforts are focusing on next generation battery technologies as a potential route for improved performance and cost, but many of these have a lengthy development trajectory or are exclusively focused on the growing electric vehicle market.

However, whilst many manufacturers choose to keep their manufacturing processes as secret know-how, improvements in the various stages of battery cell manufacturing may also provide considerable improvements to battery characteristics, subsequent performance and their CSR (corporate social responsibility) credentials, with potentially faster speed to market.

The technology seeker is an established manufacturer of consumer devices, many of which rely on lithium-ion batteries (LIB) for power generation. They are continually searching for improvements in the performance of battery components for current and future products, and actively engage with research and commercial partners to achieve this.

The technology seeker is also a major user of LIB and has excellent relationships with their suppliers, working with them to introduce new innovations, in addition to working with other partners in the battery manufacturing sector (alternative materials, next generation batteries, etc). This provides an excellent opportunity for companies and/or research organisations to accelerate a technology’s commercialisation via established manufacturers and end users.

The technology seeker will consider all forms of collaboration to access battery improvements, including supplier relationships, joint development, licensing, investment, acquisition, etc.

Technology Specification

The technology seeker is therefore interested in identifying innovative material processing and manufacturing technologies that could provide an improvement in lithium-ion battery cell performance in terms of energy density, rate capability and cycle life, among others, which will eventually result in savings of the overall production costs. They seek to collaborate with research organisations, universities, consortiums and companies from all stages of the supply chain with innovative technology applicable to lithium-ion battery manufacturing including (but not limited to):

  • Modification or enhancement of existing LIB manufacturing processes, e.g. mixing, coating and drying, calendaring, slitting, stacking, cell assembly and electrolyte filling.
  • New approaches to lithium-ion battery manufacturing, assembly and testing.
  • Technologies to increase the energy density, rate capability or manufacturability of various cell chemistries including LCO and NMC, as well as various form factors including prismatic, pouch and cylindrical format.
  • Technology to improve the corporate social responsibility (CSR) credentials focusing on environmentally friendly approach, e.g. elimination of solvents, reduction in energy consumption, recyclability, etc.
  • Potential technologies or processes should be applicable to use on a production line within 1 to 3 years.

Preferred Business Model

  • Business Collaboration (Joint Venture)
  • IP Acquisition
  • Licensing
  • Others
  • R&D Collaboration
