摘要:
A flame retarding polymer electrolyte composition containing maleimides includes a modified maleimide; a lithium salt; and at least one ionic solution in a ratio of at least 2 wt % relative to the total weight of the composition. By using the hyperbranched dendrimer-like structure of the modified maleimide as grafted skeleton for polymer electrolytes, the electrolyte composition can encapsulate an electrolytic solution continuously, thus preventing the exudation of the electrolytic solution and increasing the stability of lithium ionic conduction. Since the ionic solution is nonflammable, the safety of batteries are further enhanced when the polymer electrolyte composition is used as polymer electrolyte for a lithium secondary battery.

摘要:
The invention provides a lithium battery, including: a cathode plate and an anode plate; a separator disposed between the cathode plate and the anode plate to define a reservoir region; and an electrolyte filled in the reservoir region. A thermal protective film is provided to cover a material of the cathode plate or the anode plate. When a battery temperature rises over an onset temperature of the thermal protective film, it undergoes a crosslinking reaction to inhibit thermal runaway. A method for fabricating the lithium ion battery is also provided.

摘要:
A battery electrode paste composition containing modified maleimide(s) is provided, which has an electrode active material, a conductive additive, a binder and modified maleimide(s) as dispersant. The modified maleimide as the dispersant in the battery electrode paste composition has dendrimer-like hyperbranched structures, which can form a stable complex with the electrode active material. Therefore, owing to the excellent compatibility of the modified maleimide with the solvent in the electrode paste, the storage stability of the paste is increased. Furthermore, through formation of stable bonding between the modified maleimide and the current-collecting metal substrate, the adhesive force between the electrode film and the current-collecting metal substrate is enhanced and the cycling life of the battery product is extended.
