BYDが2020年に発表した、刀状の細長いセルを直接パックに組み込む構造のリン酸鉄リチウム(LFP)イオン電池。従来のモジュール構造を排除することで空間利用率を高め、LFPの弱点であったエネルギー密度を補いつつ、釘刺し試験でも発火しない極めて高い安全性を実現した。
Human development has accelerated the consumption of resources, and the lack of energy is a problem that human beings have to face. With the progress of science and technology and the development of the economy, and the launch of electric vehicles from various manufacturers, the technology and safety of batteries are the most concerned issues [1]. As a new battery product, blade battery has gradually improved its competitiveness at home and even abroad. How do its raw materials, cells, modules, management system and safety design stand out among many manufacturers are of great importance [2]. By studying some advantages of blade batteries, it can further infiltrate some BYD technologies into other battery manufacturers and finally, achieve common technological progress. By comparing examples and using research data, this paper studies BYD’s blade batteries and batteries of other manufacturers. Through research, people can find that BYD’s blade battery does have obvious advantages over other manufacturers in technology and safety. However, the temperature control of the battery can be further improved.
