摘要:
Disclosed is a process, for the electrolytic coupling of carboxylic acids, carried out in a polymer electrolyte membrane reactor. The reactor design (1) discloses the use of gaseous or neat liquid reactants without the use of organic cosolvents, (2) prevents the loss of platinum, and (3) permits the use of oxygen reduction to water as the cathode reaction.
摘要:
A composite electrolyte comprises (a) surface modified fumed silica filler, wherein the surface modified fumed silica comprises polymerizable groups on the surface thereof, the polymerizable groups being bonded to each other such that the surface modified fumed silica filler is crosslinked in a three-dimensional structure; (b) a dissociable lithium salt; and (c) a bulk medium which contains the surface modified fumed silica filler and the dissociable lithium salt. An electrochemical cell comprises an anode, a cathode, and a composite electrolyte dispersed between the anode and cathode.
摘要:
A composite electrolyte comprises an inorganic clay material and a dielectric solution having a dielectric constant ranging from about 50 to about 85. The composite electrolyte has an ion transference number ranging from about 0.80 to about 1.00. An electrode comprises a component selected from the group consisting of an inorganic clay filler, a polymer, and mixtures thereof. Batteries and electrochemical cells comprising the above composite electrolytes and electrodes are also disclosed.
摘要:
A carbon/nanoparticle nanofiber includes a carbon base structure and a plurality of nanoparticles that include a lithium alloy or a lithium alloy precursor. One or more nanofibers may be formed into a nonwoven fabric. The fabric may be utilized as an electrode, such as for example in a battery. The carbon/nanoparticle composite nanofiber may be fabricated by forming a polymer/nanoparticle nanofiber, such as for example by a spinning technique, and carbonizing the polymer/nanoparticle nanofiber.
