A precursor composition of a gel electrolyte is provided, which includes (1) meta-stable nitrogen-containing polymer, (2) gelling promoter, (3) carbonate compound, and (4) metal salt. The (1) meta-stable nitrogen-containing polymer is formed by reacting (a) nitrogen-containing heterocyclic compound with (b) maleimide compound, wherein (a) nitrogen-containing heterocyclic compound and (b) maleimide compound have a molar ratio of 1:0.1 to 1:10.

Gel electrolyte and precursor composition thereof and battery

An electrolyte is provided, which includes (a) 100 parts by weight of oxide-based solid state inorganic electrolyte, (b) 20 to 70 parts by weight of [Li(&#x2014;OR)OR]Y, wherein Ris Calkylene group, Ris Calkyl group, n is 2 to 100, and Y is PF, BF, AsF, SbF, ClO, AlCl, GaCl, NO, C(SOCF), N(SOCF), SCN, CFCFSO, CFSO, CFCO, SOF, B(CH), CFSO, or a combination thereof, (c) 1 to 10 parts by weight of nano oxide, and (d) 1 to 20 parts by weight of binder. The electrolyte can be disposed between a positive electrode and a negative electrode to form a battery.

Electrolyte and battery

An electrode is provided, which includes a sulfur- and carbon-containing layer having a carbon material, a sulfur material, and a binder. A sulfur content at a core part of the sulfur- and carbon-containing layer is gradually reduced to a sulfur content at two side surfaces of the sulfur- and carbon-containing layer. The electrode may serve as a positive electrode of a battery. The battery also includes a negative electrode, and an electrolyte liquid between the positive electrode and the negative electrode.

Electrode and method for manufacturing the same and battery

A separator substrate include a substrate having a bulk portion and a surface portion, the surface portion having at least one porous area with a net charge; and ionic particles coupling to at least a part of the at least one porous area. The ionic particles have a net charge of an opposite sign to the net charge of the at least one porous area. The coupling between the part of the at least one porous area and the ionic particles may result in at least one of a good electrochemical performance, chemical stability, thermal stability, wettability, and mechanical strength of the separator substrate.
