A lithium ion battery is provided, which includes a positive electrode, a negative electrode, and an electrolyte disposed between the positive electrode and the negative electrode. The negative electrode includes a current collector and a &#x3b2;-phase-based polyvinylidene fluoride (&#x3b2;-PVDF) layer coating on the current collector. The &#x3b2;-PVDF layer may have a thickness of 1 &#x3bc;m to 10 &#x3bc;m.

Negative electrode and lithium ion battery

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

A polyelectrolyte includes a first segment and a second segment, wherein the structure of the first segment is at least one of formula (1) and formula (2); the structure of the second segment is at least one of formula (3) and formula (4). The polyelectrolyte undergoes microphase separation to form a nanoscale ordered self-assembled microstructure.
