One of the points that stops thousands of people from buying an electric car has to do with recharges and range. The image left by Holy Week with the Tesla car jam is a clear example of this. However, the development of new batteries and technologies allows some vehicles to travel 2,000 kilometers without stopping to recharge. This is the solid-state battery cell from the Chinese startup Talent New Energy.
Talent New Energy has presented a new solid-state battery cell with an energy density of 720 Wh/kg. “This sets records in the industry in terms of single cell capacity and higher energy density for lithium batteries,” the company said in a statement. This means that it is expected to provide electric vehicles with a range of around 2,000 kilometers if it can be mass-produced, according to the manufacturer.
Talent explained that it has made advances in a series of key technologies for solid-state lithium batteries, including dense and ultra-thin compound oxide solid-state electrolytes, high-capacity cathode and anode materials, and an integrated solid-state battery molding process.
In this line, the battery’s positive electrode uses long cycle and high-capacity lithium-rich manganese-based materials, while the negative electrode uses an ultra-wide, ultra-thin lithium metal-based composite material that combines high cycle stability and high multiplicity, as revealed by the company. Additionally, Talent has improved the migration of charged particles within the positive electrode by constructing an efficient network for ion and electron transport.
The internally developed flexible layer materials by the company have also helped achieve an overall improvement in battery performance, which is expected to fundamentally resolve the range and safety anxiety of traditional lithium-ion batteries.
Talent was founded in 2018 and focuses on the development of solid-state lithium battery materials and technology, and in March 2022, it had received an investment from the Chinese real estate developer Country Garden.
