It is vital to develop all-solid-state batteries to accomplish carbon neutrality. However, because of their high surface resistance, these batteries have low output, restricting their applications.

VTT testing says Donut Lab’s “solid-state” battery likely matches lithium-ion; energy density measured at 298 Wh/kg, claims ...

Boron-based solid propellants have attracted considerable attention due to boron’s exceptional volumetric and gravimetric calorific values, which are critical for high-energy propulsion systems.

In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for ...
