All these approaches leverage the good performance and vast acceptance of lithium battery technologies to move to market apace. OneD is pursuing a strategy of growing silicon nanowires on the graphite anode of a lithium battery. Group14 is another company to watch in the marriage of silicon and lithium, lining up Porsche as a lead partner. Sila claims traditional lithium-ion battery tech has flatlined in terms of energy density. Energy density is especially important in heavy vehicles like the EQG because their lardiness tends to magnify the shortcomings of current batteries that have to be large and heavy to move something large and heavy even a decent number of miles, setting up a decided unvirtuous cycle. Mercedes looks like the first customer to offer the Sila tech as an elite option in the new electric EQG in 2025. That change would be roughly analogous to a Ford F-150 getting 25 MPG this year but 35 MPG next model year, an unheard of jump. Sila Nanotechnologies is replacing the graphite anode that forms a lot of the bulk and about 15% of the weight of today's lithium-ion batteries with a form of silicon that it claims will give battery cells a 20 to 40% increase in energy density while also charging faster. And while, on a practical basis, I remain more enthused about charging developments like GM's recent expansion with Pilot and EVgo or Tesla Superchargers embracing the world, here are some new battery technologies that are strong rivals for my enthusiasm. Longer range, faster charging, less range degradation and a lower sticker price: That's all that new battery technologies are to bring to electric cars. From vehicle reviews to helpful hints and the latest industry news, we've got you covered. This story is part of Plugged In, CNET's hub for all things EV and the future of electrified mobility.
