Rechargeable lithium battery for wide temperature operation WO 2013134566 A2 - http://www.google.com/patents/WO2013134566A2

Abstract Presented herein is a rechargeable lithium battery that includes a cathode, a liquid electrolyte, a solid electrolyte, and an anode. The anode is at least partially coated or plated with the solid electrolyte. The cathode may be porous and infiltrated by the liquid electrolyte. The cathode may also include a binder having a solid graft copolymer electrolyte (GCE). In certain embodiments, the liquid electrolyte is a gel that includes a PIL and a GCE. The battery achieves a high energy density and operates safely over a wide range of temperatures.

A123 Venture Technologies Agrees to Collaboration with MIT Start-up SolidEnergy

Agreement is First Example of A123�s Collaborative Development Approach

WALTHAM, Mass.--(BUSINESS WIRE)--A123 Venture Technologies, a Massachusetts technology incubator, announced today its collaboration with MIT startup SolidEnergy. This strategic partnership leverages SolidEnergy�s transformative solid electrolyte technology enabling the safe and practical use of lithium metal anodes for high energy density batteries in a wide range of applications. It is also the first publicly announced agreement under A123�s expanded R&D model introduced earlier this year.

Together the companies will gain competitive advantage by accelerating a safer high energy battery chemistry with the potential of four times the energy density compared to conventional lithium ion batteries. SolidEnergy decided to partner with A123 Venture Technologies for its world-class labs, innovation and rapid scale-up experience, and battery design expertise. A123 Venture Technologies� incubator business model was launched last spring at MIT's Knowledge Foundation conference as a way to provide start-ups with access to its development facilities, battery know-how, and market access in exchange for services revenue, equity and cooperation on commercialization. A123 and SolidEnergy both began with MIT research making this partnership a natural fit.

This partnership combines SolidEnergy�s novel battery technology called Solid Polymer Ionic Liquid (SPIL) electrolyte originally developed at MIT with the mature cell design and prototyping capabilities of A123. �We are excited to embark on our respective new journeys and to commercialize this technology in the fastest and most efficient way," said Qichao Hu, President and Chief Technology Officer of SolidEnergy.

The companies plan to jointly produce consumer electronics battery prototypes within the next year, followed by electric vehicle battery prototypes, and SolidEnergy staff will also be hosted in A123�s Waltham, Massachusetts development facility. Test results are expected to be ready for discussion with target customers in the latter part of 2014. Mujeeb Ijaz, President of A123 Venture Technologies, said, "A123 is delighted that SolidEnergy selected us as a development partner and we look forward to providing them with the ecosystem needed to bring this important technology to market in leading edge products.�
