Embodiment

[0022] Such as figure 1 As shown, the large-capacity power lithium-ion battery for aviation in this example includes a battery case 1, a battery cover 2, a current collecting column 3, a small-capacity power lithium-ion battery 4, a polar plate 5, a flat gasket 6, a nut 7 and screw 8. in:

[0023] The battery case 1 is a one-time molding structure, which is integrally machined from aluminum profiles into a cavity with a wall thickness of no more than 0.6mm around and at the bottom. Aluminum oxide protective layer.

[0024] The battery cover 2 is made of polyphenylene sulfide engineering plastics with high temperature resistance and flame retardancy.

[0025] The current collecting column 3 is formed by welding the current collecting plate and the pole, not only as the parallel carrier of the small-capacity power lithium-ion battery, but also as the output terminal of the large-capacity power lithium-ion battery for aviation.

[0026] The small-capacity power lithium-ion ba...

Abstract

The invention relates to batteries, in particular to lithium ion batteries, and aims to solve the problems that the conventional flexible package polymer lithium ion battery is likely to be damaged to cause safety accidents, and the output pole ends can crack under the harsh mechanical environment such as vibration and impact of a plane. The high capacity power lithium ion battery for aviation, provided by the invention, comprises a battery case and a small capacity power lithium ion battery, wherein the small capacity power lithium ion battery is positioned inside the battery case, and a gap is formed in the battery case, and filled with a joint mixture. The applicability to batteries is facilitated.

Description

technical field [0001] The present invention relates to accumulators, in particular to lithium-ion accumulators. Background technique [0002] Lithium-ion battery is a new type of high-energy battery developed in the early 1990s. It has the characteristics of high specific energy, high working voltage, long cycle life, small self-discharge and maintenance-free, especially its superior high specific energy The performance and small self-discharge characteristics meet the requirements of equipment for miniaturization and light weight of the power supply system. [0003] As an on-board DC chemical power supply, aviation battery packs are responsible for emergency power supply for key equipment and starting engines during aircraft use, which is a reliable guarantee for safe flight of aircraft. In order to ensure the excellent technical performance of the whole machine, the aviation battery pack is required to have the characteristics of large capacity, high output power, high s...
