Description

Technical Field

[0001] The invention relates to the technical field of storage batteries, and in particular to an impact-resistant and high-heat dissipation storage battery plastic shell. Background Art

[0002] As a core component of energy storage, batteries play a vital role in power systems, transportation, communications, and backup power supplies. They achieve effective management and utilization of energy by converting electrical energy into chemical energy for storage, and converting chemical energy back into electrical energy for release when needed. With the advancement of science and technology, battery technology is also constantly innovating. From traditional lead-acid batteries to today's lithium-ion batteries and sodium-ion batteries, not only has the energy density been greatly improved, the cycle life has been extended, but also the safety and environmental protection have been significantly improved. These advances have enabled batteries to play an increasingly important role in supporting the development of renewable energy, promoting the popularization of electric vehicles, and ensuring the stability of power supply.

[0003] As an important protective layer of the battery, the design and manufacture of the battery plastic case are directly related to the safety performance and service life of the battery. The plastic case is usually made of high-strength, corrosion-resistant materials, which can effectively isolate the external moisture, dust and impurities from corroding the inside of the battery. At the same time, it has a certain impact resistance to protect the battery from damage in harsh environments. With the advancement of materials science, modern battery plastic cases have also incorporated special functional designs such as flame retardancy and heat dissipation, further improving the safety and reliability of the battery. In addition, the lightweight design of the plastic case is also one of the current research hotspots, aiming to reduce the overall weight of the battery and improve its energy efficiency and endurance in applications such as electric vehicles and drones. Therefore, the technical development and innovation of battery plastic cases are of great significance to promoting the advancement of battery technology and the expansion of its application.
