BYD’s solid-state battery technology has attracted a lot of attention in recent years. Its main features and advantages include:
1、high energy density : BYD’s solid-state battery can reach an energy density of 400Wh/kg, which means that the same size battery can be twice as long .
2、fast charging speed : solid-state battery charging speed is very fast, can be filled in 15 minutes 80% of the charge, greatly shortening the charging time .
3、 high safety : solid state battery does not contain flammable liquid electrolyte, the risk of fire and explosion is greatly reduced, improve the safety of the battery .
4、long life : solid-state batteries have a longer cycle life and can be used more times without significantly degrading performance, typically reaching 10,000 charge and discharge cycles .
Technical details and patent information：
Byd’s all-solid-state battery uses a “staggered structure” that not only improves space utilization, but also makes full use of every inch of space inside the battery, thereby increasing the energy density 3. In addition, BYD’s battery adopts a “solid electrolyte layer” between the positive and negative electrodes, which solves the problem of electrolyte liquid leakage in the liquid battery and improves the stability and life of the battery .
Patent application status：
Byd has applied for several patents in the field of all-solid-state batteries. For example, BYD Co., Ltd. has applied for a patent entitled “all-solid-state batteries, battery packs and electrical equipment” with the public number CN 118748295A and the filing date is August 2024. The patent designs the outermost layer of the battery as a ceramic layer, using the rigidity and hardness of the ceramic layer itself, so that the battery can withstand greater pressure during the isostatic pressing process, to ensure the good performance of the battery .
Future application prospect：
Byd’s all-solid-state battery is expected to achieve large-scale application in the field of new energy vehicles. Its features such as high energy density, fast charging and long life will significantly improve the range and use experience of electric vehicles. In addition, the safety of solid-state batteries is high, which can effectively solve the safety problems of electric vehicles and reduce the risk of fire and explosion .
Conclusion：
BYD’s solid-state battery technology has significant advantages in energy density, charging speed, safety and life, and is expected to occupy an important position in the new energy vehicle market in the future.
