Abstract: A positive electrode and a battery employing the same encapsulant composition are provided. The positive electrode includes a positive electrode active layer and a first layer, wherein the first layer is disposed on the positive electrode active layer, and the first layer includes a lithium-iron-phosphorus-containing oxide and a first binder. The electric resistance ratio of the first layer to the positive electrode active layer is greater than or equal to 100.

Abstract: 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.

Abstract: A lithium ion secondary battery includes LiFePO4 as a major component of the positive electrode active material. In order to implement the high rate capability with 10 C/1 C rate larger than 80%, the invention designs a positive electrode on a current collector with a ratio (A/t) of coating area to coating thickness greater than 1.2×106 (mm) and uses more than one tab on the current collector. The design of the invention can be applied to other active materials with low conductivity as the positive electrode for lithium ion battery.
