Lithium battery innovation technology to boost the energy revolution

Industry definition

Lithium batteries are recyclable rechargeable batteries widely used in portable electronic devices, electric vehicles and energy storage systems, and are favored for their advantages such as high energy density, long cycle life and no memory effect. The working principle is that lithium ions move between the positive and negative electrode materials to achieve the storage and release of electrical energy.

The concept battery with lithium as the active material was proposed as early as the beginning of the last century. In 1912, Swiss chemist Gilbert N. Lewis proposed the concept of a lithium-silver battery using lithium metal as a negative electrode and silver as a positive electrode. Until 1991, SONY Group achieved the world's first commercial production of lithium batteries. With the popularity of the word "portable", lithium batteries have been popularized on small electronic devices such as mobile phones, and then extended to the automotive field, many car companies have participated, and the focus of lithium battery research and application has begun to shift to the field of new energy vehicles. Up to now, lithium batteries have achieved great success and wide application in the fields of electronic equipment and electric vehicles.

For the future, lithium batteries in the field of aviation and military applications will have important strategic significance. In aerospace, energy density has always been a key factor. The specific energy and specific capacity of lithium batteries are high, which can provide more power reserves for aircraft, thereby extending flight time or increasing payload capacity.
