Learn MoreThrough the patented blade battery technology, the specific energy density of a lithium-ion battery can be increased from 251Wh / L to 332Wh / L, an increase of more than 30%.
Located in the city's Bishan District, the factory is currently the only production base for the Blade Battery. It possesses a highly demanding production environment and much of BYD's self-developed Blade Battery production equipment. The factory has a total investment of 10 billion yuan with an annual production capacity of 20GWH.
Battery production is a complex and long process, mainly including raw material extraction and processing, electrode and other components manufacturing, cell manufacturing, pack assembly, etc. [242, 243]. There are strict indoor environmental conditions and cleanliness [244, 245], resulting in high energy consumption.
The height of the Blade Battery is reduced by ~50 mm, compared with regular LFP battery back with modules, providing more space to the passengers and decreasing the coefficient of drag (0.233 cd for BYD Han). In the Z direction, the structure of the Blade Battery is completely different from conventional module-based battery packs (Figure 3).
The conventional battery manufacturing process is from cell to module, and then from module to pack. This intermediate step divides the battery into separate modules, each of which can have its own independent battery management and diagnostic systems.
In addition to solving the issue of endurance – once a previous limiter to the development of traditional lithium iron phosphate batteries – the Blade Battery can be charged from 10% to 80% of its full capacity within 33 minutes, supporting the BYD Han EV's acceleration of zero to 100 km/h in 3.9 seconds.
