Solid-state batteries have higher energy and are safer than conventional batteries. Penn State researchers have proposed an improved solid-state battery production method that enables the integration of multiple materials for better batteries—cold sintering.

"We wanted to paint as comprehensive a picture as possible of how lignocellulose can replace currently widely used non-renewable resources such as smart devices or solar cells," said Jaana Vapaavuori, Assistant Professor of Functional Materials at Aalto University.

Recycling method of cathode material for decommissioned lithium iron phosphate batteryLithium-ion power battery cathode materials include lithium cobaltate, lithium manganate, lithium nickelate, lithium iron phosphate and ternary materials.

The solar fiber optic lighting system, combined with a series of patented technologies such as sun tracking and lens focusing, greatly improves the brightness of sunlight at the focal point, and guides the light to the place that needs lighting through the optical fiber with high light rate.

In addition, by increasing the lithium concentration in the water leachate to the maximum concentration at which the lithium in the black powder dissolves, the rate of lithium recovery is increased.

According to foreign media reports, researchers at DGIST (Gyeongbuk Institute of Science and Technology, South Korea) have demonstrated that lithium metal batteries can be cycled over a wide temperature range (2-60°C) by employing a new high-concentration electrolyte dilution technique.

Energy storage operation and maintenance solutions: With the increasing role of information technologies such as dynamic interconnection, big data, and the Internet of Things in promoting the transformation and upgrading of the traditional energy industry, "smart manufacturing".

Energy is everywhere, but energy supply is still in short supply. The vast northwest region contains a lot of renewable energy such as "wind" and "light", but these energy sources are often too far away from the cities that are in the center of energy consumption.
