Tailan New Energy VS Quantumscape | NEW SOLID STATE BATTERY changes everything

Talent New Energy, a relative newcomer to the EV battery industry, has promised a solid-state battery that could outdo the rest of the EV industry.
At the tail end of the Malaise Era, the American auto industry was infamously upended by Japanese automakers who introduced the brougham-weary public to such novel ideas as “compact vehicles” and “fuel economy.” Aside from a few novelties like the Nash Metropolitan, the American auto industry had generally avoided making any vehicle that couldn’t fit a V-8 under its hood.
In a similar way, Chinese manufacturers seem to be priming themselves to take over the still-nascent EV industry. Battery company Tailan New Energy (which anglicizes its name to Talent New Energy) has announced that it has a solid-state battery that puts everyone else in the industry’s wildest claims to shame.
Tailan New Energy has created what could be the world’s highest-capacity solid-state battery.
While manufacturing plans remain uncertain, the closest SSB competition could be from fellow Chinese manufacturer Nio, which has actually driven a semi-solid-state battery on public roads.
Tailan (alias Talent) New Energy has developed a solid-state battery that can store even more energy in less space than other solid-state battery designs. The company's battery stores its energy in “ultra-thin” composite oxide electrolytes. TNE's electrolytes can hold an astonishing 720 watt-hours per kilogram of material.

For reference, this means a one-kilogram battery (the weight of one liter of water) could power an 1875-watt hairdryer for 23 minutes.
It has also designed “high-capacity” electrodes that can get electricity out of the battery and into a vehicle’s wiring as fast as possible. As is the case with the current generation of lithium-ion EV batteries, Tailan New Energy’s battery design is subdivided into multiple cells rather than a single large unit. Tailan's solid-state electrolytes and other design developments allow for the battery cells to be very thin. This would give automakers more freedom when it comes to battery placement.
It’s worth noting that no independent company has tested Tailan New Energy’s battery design. (Or at least, no such tests have been publicized.) However, if TNE’s specifications are correct, its battery has at least twice the energy density of any EV battery on the road today. The closest solid-state competitor is Nio, which put its semi-solid-state battery through a 648-mile single-charge road test. Other auto companies have made extravagant solid-state promises, but so far only Nio has actually put a (semi-)SSB into a vehicle and then driven it on public roads.
While most of the major car manufacturers are at least researching solid-state batteries, the biggest developments have come from China.
Nio has put a semi-solid-state battery through a 648-mile road test. No other auto company has put an SSB onto public streets.
Other auto companies are also trying to make solid-state batteries. None of them have driven an EV powered by one.
So far, the biggest developments in solid-state batteries have come from China. Most notably, EV manufacturer Nio put a semi-solid-state battery into one of its vehicles and drove it 648 miles on a single charge. The company’s CEO personally drove the car, and the entire journey was livestreamed.
Nio (and its battery supplier WeLion) are part of a recently formed Chinese solid-state battery consortium called the China All-Solid-State Battery Collaborative Innovation Platform (CASIP for short). This is an alliance of the biggest players in China’s EV and battery industry, along with several relevant government agencies.
While CASIP is still a very new entity, its effects have already been felt on the other side of the Pacific. CASIP member CATL announced that it would no longer supply batteries to its hitherto biggest customer, Tesla. It will help Tesla establish its own factories and provide the tooling. But after the battery factory is in operation, CATL will sever all business relations. (This may explain why Tesla recently filed a relatively vague battery patent.)
The main newsmaker in the world of solid-state batteries has been Toyota. Unfortunately, Toyota has not produced a car containing an actual solid-state battery. It has long made extravagant range claims (most commonly 745 miles, though it has sometimes promised numbers north of 900 miles per charge). It had long promised a battery release date by 2027.
