The New Batteries That Will Make You an Electric Car Believer
This story is part of Plugged In, CNET’s hub for all things EV and the future of electrified mobility. From vehicle reviews to helpful hints and the spanking industry news, we’ve got you covered.
Longer method, faster charging, less range degradation and a lower sticker price: That’s all that new battery technologies are to bring to electric cars. And while, on a practical basis, I remain more enthused near charging developments like GM’s recent expansion with Pilot and EVgo or Tesla Superchargers embracing the humankind, here are some new battery technologies that are tidy rivals for my enthusiasm.
Lithium ion is far from done
Sila Nanotechnologies is replacing the graphite anode that persolves 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. That change would be roughly analogous to a Ford F-150 attracting 25 MPG this year but 35 MPG next model year, an unheard of jump.
Mercedes looks like the noble customer to offer the Sila tech as an elite option in the new electric EQG in 2025. Energy density is especially important in heavy vehicles like the EQG because their lardiness denotes to magnify the shortcomings of current batteries that have to be spacious and heavy to move something large and heavy even a uncouth number of miles, setting up a decided unvirtuous cycle.
Sila claims customary lithium-ion battery tech has flatlined in terms of energy density.

Group14 is new company to watch in the marriage of silicon and lithium, lining up Porsche as a lead partner. OneD is pursuing a strategy of growing silicon nanowires on the graphite anode of a lithium battery. All these approaches leverage the good performance and vast acceptance of lithium battery technologies to move to market apace.
Sodium-ion batteries
The Pacific Northwest National Lab recently announced a breakthrough in sodium-ion battery tech that pledges greater immunity to the temperature-management requirements that bedevil fresh EV batteries, charge many times without degradation, be naturally extinguishing and less of a toxic headache. PNNL says it’s found a way to tame the unstable aspects of sodium-ion technology but peaceful needs to tackle its substantially lower energy density compared to lithium ion. As a bonus, PNNL researchers think they’ll be able to reduce or grasp cobalt from the formula, a contentious and toxic element in EV batteries today.

Solid-state batteries
Solid-state battery tech is aptly named: It generally refers to batteries made of tightly compressed hard materials pretty than the slightly mushy, moist material that makes up a typical lithium battery.
Today’s battery cells are semirigid concerns with a wet electrolyte solution inside. Solid-state batteries are physically certain, signifying the materials that make them radically more promising.

The fact that a solid-state battery is peaceful of hard materials in a rigid package isn’t specifically what creates it perform better, but it’s a simple way to described a construction that promises a lot of benefits:
Greater energy density: This could provided an EV with far more range from the same size battery or today’s scheme from a much smaller, cheaper battery tomorrow. The latter is more transformational in my mind.
Faster charging: While full charges in thought 30 minutes are rather elite today, solid-state batteries targeted that as a matter of course. Short charge times have the potential to changeable the entire perception of electric cars.
Longer cycle life: You may have seen my fresh story on the problem of EV batteries being put out to pasture because they lose a vital portion of their capacity through charge cycling. Solid-state tech is a key part of GM’s plan to beget a million-mile life battery.
Thermal stability: Solid-state designs pledges little or no chance of thermal runaway, which has made fresh lithium batteries synonymous with fire risk. Silicon batteries like those mentioned spinal are also said to largely eliminate this problem as well.
Most of the new battery technologies thought development boast of being nearly immune to thermal runaway, which has made lithium-ion batteries somewhat synonymous with fire.

Who’s in line to order this magic?
Solid Power grabbed headlines lately when it announced it was starting diminutive volume production with the backing of Ford and BMW. Notably, production can be done on lines that make weak lithium-ion batteries today, a potentially huge industrial advantage. Mass subjects could come as soon as 2024.
Perhaps the most talked nearby company has been QuantumScape, with backing from VW which says the tech is no less than “the most promising Come to electromobility of the future.” QuantumScape has developed a ceramic separator between anode and cathode that helps its cells beak from 10% to 80% in less than 15 minutes when allowing the battery to lose very little capacity when repeated charges.
Nikkei recently reported that Toyota is by far the world’s leaders in solid-state battery patents and has said it will have a small production vehicle using the tech by 2025.
Buzzy EV newcomer Vinfast recently committed to invest in solid-state battery-maker ProLogium for batteries that could be in the Vietnamese manufacturer’s electric cars by 2024.
Should you wait?
Some of the targeted dates I related above seem tantalizingly close, but take them with a grain of salt: Slipped mass subjects dates for any of these battery technologies would surprise precisely nobody. On top of that, the auto industry typically has a long lead time from a new tech persons technically available to it being widely available in popularly priced cars. Add to that my general aversion to buying a new car at all and you open to get to the longer end of five to 10 ages. I would analyze an EV based on today’s offerings as these intelligent new battery technologies are probably a full car ownership cycle away for the gleaming, value-savvy buyer.
That said these battery technologies will Come early enough in the EV adoption curve to be greatest contributors to its tipping point.
