A new solid - state lithium battery developed in Belgium is described

Belgium's interuniversity microelectronics center has developed an innovative solid-state lithium-ion battery that can reach an energy density of 200 watt-hours per liter after being charged for two hours, British media said.

The intercollegiate microelectronics center is the world's leading center for nanoelectronics, energy, and digital technology research innovation, and a partner of EnergyVille, a research organization.

According to the report, the battery represents a milestone in our development blueprint. It will surpass liquid lithium ion batteries and reach the level of 0.5 hour full 1000 watt-hours per liter by 2024. Following such a clear path of performance improvement, the inter-university microelectronics center's battery technology will become the future fast charging remote electric vehicle battery industry competitors.

The future of mobility is largely electric, powered by fast-charging, safe and compact batteries. Researchers at the intercollegiate microelectronics center are developing next-generation batteries that increase the energy density of batteries by replacing liquid electrolytes with solid ones.

Recently, the inter-university microelectronics center has developed a solid nanocomposite electrolyte with outstanding electrical conductivity, up to 10 millisims per centimetre, which is expected to be further improved in the future. The interuniversity microelectronics centre has used the new electrolyte to build a prototype battery. The prototype battery has an energy density of 200 watts per liter and a charging speed of two hours.

"Our results show that we can make solid-state batteries that have the potential to achieve the capability of liquid-electrolyte batteries in a similar way," said Philip verriken, lead scientist and program manager at the interuniversity center for microelectronics. But unlike liquid electrolyte batteries, our solid-state batteries are compatible with lithium metal anodes and aim for a charge rate of 0.5 hours per 1,000 watts per liter. "This, coupled with long life and high safety performance, makes this compact battery technology promising for future long-range electric vehicles.

To further improve the performance of the battery, the interuniversity microelectronics center is working on combining nanoparticle electrodes with nanocomposite electrolytes, the report said. The intercollegiate microelectronics center USES an ultrathin coating as a buffer layer to control the interaction between the active electrode and the electrolyte.
