Battery tech firm ProLogium has taken the wraps off its 100% silicon composite anode battery. Highlighting its potential for use in EVs at the ongoing Paris Motor Show, the Taiwanese company claimed a major leap in energy density and charging efficiency, promising 186 miles (300 km) of range from a five-minute charge.

Let's dive into the juicy numbers right away. ProLogium said its new battery system manages an energy density of 321 Wh/kg. That's a huge leap compared to current electric vehicle (EV) batteries. For comparison, the 53 kWh battery pack in a Hyundai Ioniq 6 is rated at 153 Wh/kg, Tesla's superior 4680 cell is believed to come in at 232.5 Wh/kg.

This tech also charges awfully fast: it can go from 5% to 60% in just 5 minutes, and can reach 80% in 8.5 minutes. ProLogium highlighted how that's more than 80% faster than current EV charging tech on the market. That means it has the potential to solve limited public charging stations and long wait times while you're powering up on the road.

These batteries also feature a modular design, which should make them easier to repair and recycle – and hopefully bring down the cost of EV ownership in the vehicles they power.

ProLogium noted that it's also expanding from R&D into commercializing its energy solutions. It's partnering with German automotive drivetrain and tech firm FEV to begin manufacturing battery packs in the near future.

That sets the stage for serious competition in the race to deliver next-gen EV batteries. A couple of weeks ago, Panasonic noted its light and compact 4680 cells were set to go into mass production. And last November, Panasonic partnered with Washington-based Sila to use the latter's silicon anode tech to achieve a 25% increase in battery energy density.

Looking further into the future, there's a carbon fiber-based technology from Sweden that sees the battery doubling as the load-bearing material for cars. That makes it essentially 'massless,' since its weight doesn't add to that of the vehicle separate from its structure.

Given the growing need to make the switch from combustion-engine vehicles to EVs, we'll take all the range anxiety cures anyone can come up with.

Even casual EV enthusiasts know that 321 Wh/kg is mediocre. Everyone is already scoffing at new solid state batteries boasting only 400 Wh/kg. Besides, no math dropout would even dare to claim miles per charge without knowing vehicle power and weight.

How are they going to get rid of the heat generated in that fast charging speed? And how many cycles can this thing stand, with what proof of useful life? Vaporware so far.

Hate to think of the charging current needed to achieve those charge speeds.
The ground and electric feed infrastructure will need a massive re-think to give that capability.

(Oh, dear!):
@ veryken: The - by far - more important issue than weight in terms of range/charge is drag coefficient as 'range anxiety' is usually only encountered on long trips where most of the travelling will be done at relatively constant highway speeds and therefore the weight of the vehicle is comparatively irrelevant. Likewise vehicle power. The vast majority of cars fall into a relatively narrow bracket in terms of weight, drag coefficient and manner of driving and therefore it's not unreasonable for a battery manufacturer to take an 'average use scenario' position when projecting range for vehicles equipped with their batteries.

@ Jinpa
Perhaps they don't get hot? The right sort of battery chemistry could avoid the majority of the heating affects that traditional lithium ion battery technology suffers from. Besides which, I can't see why this company would be unable to deal with this question when so many others companies already with very quick charging EV batteries already in production can.

@ Pete-y
I agree except that the use of on-site large battery storage would mitigate a great deal of the need particularly heavy duty power supplies i.e. the battery will trickle charge from a much more conventional supply ready to dump energy very quickly via a heavy DC connection to the EV. Actually, I don't understand why this is not already used at some of the more difficult/expensive to get to DC charging locations whose construction has stalled because of this very problem.

Like the idea of potentially turning battery packs into load-carrying parts of the vehicles! Still, I bet, even this change of design (when realized and appearing on the market) will not be a match in its attractiveness to another design offering a reasonable battery-swap solution!

It's $/Wh that will make people choose an EV.

No one cares how fast a car can charge if they're paying 50% of a combustion car.
