Provided herein is a method of manufacturing a nanoscale coated network, which includes providing nanofibers, capable of forming a network in the presence of a liquid vehicle and providing a nanoscale solid substance in the presence of the liquid vehicle. The method may also include forming a network of the nanofibers and the nanoscale solid substance and redistributing at least a portion of the nanoscale solid substance within the network to produce a network of nanofibers coated with the nanoscale solid substance. Also provided herein is a nanoscale coated network with an active material coating that is redistributed to cover and electrochemically isolate the network from materials outside the network.

Disclosed herein are methods for producing an ultra-dense and ultra-smooth ceramic coating. A method includes feeding a solution comprising a metal precursor into a plasma sprayer. The plasma sprayer generates a stream toward an article, forming a ceramic coating on the article upon contact.

A diaphragm and a high-voltage battery including the diaphragm. A modification layer is coated on a surface of an inorganic ceramic particle, the modification layer can adsorb transition metal ions precipitated from an electrode material, thereby preventing the transition metal ions from forming transition metal precipitates on a surface of a negative electrode and improving safety, rate performance and cycle performance of the battery. At the same time, since the modification layer is coated on the surface of the inorganic ceramic particle, thus it will not have a significant impact on an internal resistance of the battery, and thereby not reducing the rate, low temperature, and cycle performances of the battery.
