Case For High-Power Rechargeable Lithium Battery

Disclosed herein is a case which protects a plurality of flexible lithium polymer unit cells, has a compact structure to reduce volume, has a simple assembly process, and minimizes heat generated during a high-power charging or discharging operation. The battery case includes a pouch support frame to support a pouch of a unit cell having the pouch and electrode terminals. A heat radiating part having the shape of a shelf is provided on a surface of the pouch support frame, and defines a space for dispersing heat generated from the pouch. A terminal support having the shape of a wall is provided on an edge of the heat radiating part, thus supporting the electrode terminals of the unit cell.

Battery stack arrangement

The present invention relates to a battery stack arrangement (50) comprising at least one bipolar battery. Each bipolar battery comprises a plurality of battery cell arranged between endplates (22,23). Each battery cell is provided with a seal (24) arranged around the entire periphery of each cell, and a sealing pressure Fseal is applied over the seal to prevent electrolyte leakage between adjacent cells. The battery stack arrangement further comprises a mounting frame (57) including: at least two mounting units (58,59) and at least one tie unit (60, 60′, 60″) holding said mounting units together. The bipolar battery is arranged between the mounting units (58,59), and the battery stack arrangement further comprises at least one spacing element (61) arranged between the mounting units (58,59) and each spacing element (61) abuts against at least one endplate (22,23) and is held in place by said mounting frame (57) to create a stack pressure Fstack, independent of the sealing pressure Fseal. The stack pressure is controlled by the tie unit.

Thermal management material, preparation method thereof and application

The invention discloses a thermal management material, a preparation method thereof and an application. The method includes the steps: in weight percentage, slowly adding 5-10% of multilayer flake graphene and 2-5% of carbon fibers into 60-80% of molten long-chain alkane, and uniformly stirring mixture to obtain initial phase-change materials; adding 2-5% of flame retardants into the initial phase-change materials to uniformly stir to obtain phase-change materials of compound flame retardants; mixing 5-10% of reinforced resins and 5-10% of oil-absorptive resins to heat to a molten state, adding the phase-change materials of the compound flame retardants, continually stirring for predetermined time, and cooling the mixture to obtain the thermal management material. The thermal management material prepared by the method has high flame resistance, insulation performance, high-thermal storage performance and heat-conducting performance, the thermal management material contacts with the surface of a new-energy power lithium battery, good heat-conducting effect can be achieved, heat storage effect can be also achieved, heat moment rising of a lithium battery pack is solved, thermal runaway risks are reduced, and safety of the battery pack is improved.
