  • Patent number: 10658698
    Abstract: Syntheses of graft copolymers based on PEO and fluorinated functional groups are described. Grafting of fluorinated groups reduces the Tm of PEO and also increases the miscibility of PEO with ionic liquids, so that addition of ionic liquids improves ionic conductivity even at room temperature. The disclosed copolymers containing fluorinated functionality have superior safety and are more flame retardant as compared to traditional electrolytes. Such copolymers can be used as either solid or gel electrolytes in Li batteries.

  • Patent number: 10622672
    Abstract: Composites of lithium-ion-conducting ceramic and polymeric materials make superior separators and electrolytes for use in lithium batteries. The ceramic material provides a high conductivity pathway for lithium-ions, enhancing the properties of the less conductive polymeric material. The polymeric material provides flexibility, binding, and space-filling properties, mitigating the tendency of rigid ceramic materials to break or delaminate. The interface between the polymer and ceramic can be made to have a low ionic resistance through the use of additives and coatings.

  • Patent number: 10593995
    Abstract: Synthesis and electrochemical properties of a new class of polymer electrolytes based on polar polysiloxane polymers is described. Unlike ethylene oxide-based polymers, these materials are oxidatively stable up to at least 4.2 V, the operating voltage of high energy cells that use cathode materials such as lithium nickel cobalt aluminum oxide (NCA) and lithium nickel cobalt manganese oxide (NCM). Use of these polymers electrolytes as an alternative to PEO in solid-state lithium batteries is described.

  • Publication number: 20200028154
    Abstract: The accurate determination of the state-of-charge (SOC) of batteries is an important element of battery management. One method to determine SOC is to measure the voltage of the cell and exploiting the correlation between voltage and SOC. For electrodes with sloped charge/discharge profiles, this is a good method. However, for batteries with lithium iron phosphate (LFP) cathodes the charge/discharge profile is flat. Now, by using the materials and methods disclosed herein, an amount of cathode active material that has a sloped charge/discharge profile is mixed with LFP in a cathode, which results in a charge/discharge profile with enough slope that the SOC of the battery can be determined by measuring the voltage alone.

    Abstract: Electrode assemblies for use in electrochemical cells are provided. The negative electrode assembly includes negative electrode active material and an electrolyte chosen specifically for its useful properties in the negative electrode. Such properties include reductive stability and ability to accommodate expansion and contraction of the negative electrode active material. Similarly, the positive electrode assembly includes positive electrode active material and an electrolyte chosen specifically for its useful properties in the positive electrode. These properties include oxidative stability and the ability to prevent dissolution of transition metals used in the positive electrode active material. A third electrolyte can be used as separator between the negative electrode and the positive electrode. A cell is constructed with a cathode that includes a fluorinated electrolyte which does not penetrate into the solid-state polymer electrolyte separator between it and the lithium-based anode.
