On April 4th, Taiblue New Energy announced a significant breakthrough in the development of automotive-grade solid-state lithium batteries via its official public account.
Claiming to have developed the world's first automotive-grade single-cell battery with a capacity of 120Ah, the measured energy density reaches a remarkable 720Wh/kg, setting a new industry record for both single-cell capacity and highest energy density for downsized lithium metal batteries.
It's understood that the energy density of lithium iron phosphate batteries generally ranges from 100 to 160Wh/kg, while ternary lithium batteries typically fall between 150 and 250Wh/kg.
This implies that for the same amount of electricity, the weight of this solid-state lithium battery is only one-fifth that of mainstream batteries currently available!
To achieve this solid-state lithium battery, the company made breakthroughs in several key technologies, including ultra-thin dense composite oxide solid electrolytes, high-capacity advanced positive and negative electrode materials, and integrated solid-state battery forming processes, among others.
According to reports, the solid-state lithium battery released by Taiblue New Energy this time uses high-capacity, long-cycle lithium-rich manganese-based materials for the positive electrode and ultra-wide, ultra-thin, and high-cycle-stable composite lithium metal-based materials for the negative electrode.
Simultaneously, to address the solid-solid interface impedance issue of solid-state lithium batteries, it also incorporates Taiblue New Energy's unique high-performance oxide composite solid electrolyte.
Meanwhile, Taiblue New Energy has improved the migration capability of charged particles within the positive electrode by constructing an efficient ion and electron transport network. Coupled with self-developed interface flexible layer materials, it effectively reduces interface impedance while enhancing interface stability.
This achieves comprehensive improvement in battery performance and is expected to fundamentally address concerns about the range and safety of traditional lithium-ion batteries.
