The hydrogel is polymerized in situ , resulting in a well-connected 3D network structure of Si nanoparticles (SiNP) coated by the conducting polymer. A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si. Click to enlarge.

The graphene cage acts as a mechanically strong and flexible buffer during deep cycling, allowing the silicon microparticles to expand and fracture within the cage while retaining electrical connectivity on both the particle and electrode level. —Stanford postdoc Kai Yan. 2015.29.

Fifty years ago, there were no EVs available commercially. I ordered a controller from a company in California, which used a single power Darlington transistor, and 4 deep cycle 12-volt batteries.” Most of us just did our own conversions. Either that, or we’d buy one from someone else who did,” he said.

Wireless charging is nothing new— Charged has covered wireless EV charging since at least 2011—but it may be that its true value is only coming into focus now, as more and more commercial and transit fleets are electrifying. We connect high-power communication lines into the DC charging system of the car. John Holland: Yes.
