Knowing the state of charge of lithium-ion batteries, used to power applications from electric vehicles to medical diagnostic equipment, is critical for long-term battery operation.
Buildings are energy intensive and contribute to carbon dioxide emissions while accounting for one-third of energy consumption worldwide. Heat pump technology can assist in electrification and decarbonization efforts.
The proposed solid electrolyte can solve the problem of manufacturing solid electrolyte when heating and densifying the solid electrolyte powder. The material can avoid also the use of solid electrolyte additive with cathode to prepare a catholyte.
Concrete floor slab flatness and levelness are parameters often specified in construction documents that contractors must meet to ensure a high quality of construction. However, the measurement of these parameters is cumbersome and time-consuming.
This invention proposes a Honeycomb-DD coupling structure that addresses the shortcomings of the conventional honeycomb coil array and gathering the advantage of DD and honeycomb designs advantages in a single design.
Free-standing, thin films were fabricated with a binder resulting in nearly an order of magnitude thickness decrease while increasing porosity and activation energy. These effects of such diminished significantly. Free-standing films could be fabricated with a binder.
This technology creates a light and metalless current collector for battery application. Cathodes coated on this new current collector demonstrated similar contact resistance, lower charge transfer resistance and similar or high rate performance.
Wireless charging systems need to operate at high frequency, at or near resonance, to maximize power transfer distance and efficiency. High voltages appear across the inductors and capacitors. The use of discrete components reduces efficiency, increases system complexity.
