The important idea of the insulation layer HRL is to place it between the positive and negative electrodes, which can prevent the collapse of the isolation film in extreme situations, thus ensuring a certain resistance value of the battery cell even during rapid temperature rise. On the first generation lithium battery, HRL is coated on the positive electrode of the battery cell.

Through testing and verification, it has been shown that this design method can effectively cope with internal short circuits.

In order to verify the safety and reliability of the first generation lithium battery, Toyota launched 150 demonstration vehicles from 2006 to 2009, and it was only in 2011 that the PriusAlpha was officially put into mass production. Through the collection and analysis of data on these vehicle batteries, the design method of the first generation battery has been basically demonstrated. On the basis of the first generation battery, further research and development will be carried out to meet various high-performance requirements for the second generation lithium battery.

For electric vehicles, safety always comes first. From the various policies, norms, and standards of this year, the country is also guided by this approach. Firstly, safety must be ensured, and on this basis, other performance indicators such as energy density will be further proposed.
