Diversity-Oriented Polymers of Intrinsic Microporosity (2018-128)
A new class of monomers from which diversity-oriented libraries of intrinsically microporous polymers are prepared with highly desirable characteristics for manufacturing and service life as a membrane, or other component, for applications such as gas separations, fuel cells, batteries, water purification, and many others.
Longer Cycle Life, Lower Cost All-Organic Redox Flow Batteries (2016-126)
A technology optimizing all-organic redox flow batteries by pairing redox-active oligomeric organic molecules and size-selective porous polymer membranes that block the crossover of active molecules and allow the movement of supporting ions in solution. The Berkeley Lab technology also uses small (relative to polymers) molecules that keep the solution viscosity and electron transfer kinetics low and fast.
Redox-Active Supramolecular Binders for Lithium Sulfur Batteries (2016-080)
A technology to improve electron and ion transport in solid-state lithium sulfur (Li-S) battery electrode binders. This technology will enable high capacity, low cost, and large scale Li-S cells competitive with lithium ion batteries.
Low Cost Stabilizer to Improve Lithium Sulfur Batteries (2016-040)
Carrageenan, a naturally-occurring material works as well as a synthetic polymer to buffer the polysulfide shuttle effect typical of Li-S batteries and, instead, maintain the integrity of the sulfur electrode to improve electrochemical performance.
Conductive Binder for Lithium Ion Battery Electrode (2643, 2643A, 3279)
Highly conductive polymer binder materials that significantly improve the viability of using silicon as an electrode material in lithium ion batteries for high power and high energy applications. When used in the fabrication of negative silicon electrodes, the Berkeley Lab binder materials deliver significantly improved battery life. When combined with high capacity positive electrode materials, the conductive binder materials promise to double energy density.
Silicon Composite Electrode for Advanced Lithium Ion Battery (2890, 3053)
Combined lithium metal with the Berkeley Lab conductive binder plus other materials to create a hybrid electrode system for use in lithium ion batteries. The technology increases the energy density of the lithium ion battery and enables the use of a positive electrode that does not contain lithium ions. It contributes to improved battery safety by circumventing lithium metal dendrite formation. Improvements to processing conditions for Berkeley Lab’s silicon composite electrode technology have achieved higher energy density and prolonged cycling and storage lifetime by capacity in the electrode.
Block Copolymer Cathode Binder to Simultaneously Transport Electronic Charges and Ions (3025)
A highly efficient lithium ion battery in which a single inactive material—a polymeric binding agent—serves as a binder that holds active cathode materials together and as a two-lane conductor that simultaneously carries lithium ions and electronic charge.
