Simply whenever you thought the EV information cycle was slowing down, right here comes the Chinese language startup IM Motors with information of a brand new EV sporting a production-ready solid-state battery, able to roll off the meeting line. In the meantime Robert Zeng, founder and chairman of the main Chinese language EV battery agency CATL, claps again together with his ideas in regards to the state of solid-state expertise. Maintain on to your hats…
Robert Zeng: Strong-State Battery Technology Is Coming, Ultimately
CleanTechnica has heard a lot speak of solid-state EV battery expertise over time, the concept being that at the moment’s standard liquid-electrolyte EV batteries are due for a makeover. A battery with a solid electrolyte is trickier to formulate, however the payoff is faster charging, longer range, and improved security.
Different advantages can embody a provide chain with fewer (or no) hazardous supplies, and improved efficiencies in end-of-life dealing with (see heaps extra CleanTechnica solid-state coverage here).
As one of many world’s main EV battery innovators, CATL (brief for Up to date Amperex Technology Co., Restricted) is a daily function right here at CleanTechnica. Nevertheless, except there’s one thing we don’t find out about, the corporate has no plans to introduce a solid-state battery any time quickly. Two years in the past, the corporate suggested {that a} solid-state EV battery would not be ready for prime time till 2035, or maybe later.
That doesn’t imply CATL is standing nonetheless when it comes to EV battery enhancements. Semi-solid expertise is already on the desk, for instance. Final week, CleanTechnica editor Zach Shahan additionally noticed that CATL is working with the battery-swapping firm NIO on growing the lifespan of a swappable EV battery.
“In fact, everybody and their brother is engaged on solid-state batteries,” Shahan concluded.
Which may be so, however Robert Zeng lit the Intertubes on hearth earlier this week, after Monetary Occasions reported that “China’s ‘battery king’ dismisses EV battery commercialisation as years away” — that means Zeng, in fact.
That’s the headline. The story is behind a paywall, although yow will discover excerpts by different sources. The gist of it’s that Zeng anticipates a real solid-state EV battery finally, however for now a “condensed matter” semi-solid chemistry — such because the one launched by CATL final yr — represents a major enchancment within the area.

IM Motors: We Too Are Launching A Manufacturing-Prepared Strong-State EV Battery!
That brings us to IM Motors. The corporate was based in 2020 because the A-list model of China’s state-owned SAIC, which additionally holds the MG nameplate in its roster.
Only one yr later, in 2021, IM Motors launched its L7 electrical automotive into orbit at Auto Shanghai, billing it as a “new development of intelligent electric luxury vehicles.”
There was nothing within the press package a few solid-state battery, however there have been loads of bells and whistles.
“As IM Motors’ flagship automotive mannequin for main superior clever autos, the L7 operates on the baseline logic of ‘information figuring out expertise, whereas software program defining autos’ within the period of AI,” the corporate defined.
“A newly constructed clever driving system, gorgeous supercar efficiency, an distinctive personalized driver’s seat and 5G social media skills, are all among the properties that make this clever automotive luxurious. They fully redefine the expectations of a automotive within the ‘Clever Period,’” they added.
The solid-state battery lastly popped up in February of this yr, when Motor Authority reporter Viknesh Vijayenthiran reported the debut of the L6 compact sedan.
“Chinese language auto big SAIC used this week’s 2024 Geneva auto present to debut the L6 compact sedan, the most recent mannequin from its newly established model IM,” Vijayenthiran wrote.
“IM was brief on particulars for the L6 however stated a minimum of one model will ship 0-62 mph acceleration in lower than three seconds,” Vijayenthiran added. “There shall be a normal lithium-ion battery and an out there solid-state battery.”
Citing an organization spokesperson, Vijayenthiran additionally reported that each batteries are “anticipated to be out there on the 2025 launch.”
Ummm… About That Manufacturing-Prepared Strong-State Battery…
That sounds fairly definitive, however the satan could also be within the particulars. Earlier this week, Car News China was amongst these reporting that these particulars won’t be out there for an additional week or so.
“IM Motors declare that the L6, on account of launch in Could, will include the business’s first mass-produced ultra-fast charging stable state battery,” Automobile Information China reporter Mark Andrews reported on March 25. “Extra particulars shall be introduced on the IM L6 Technology Convention on April 8 however we already know that the brand new battery shall be 130 kWh.”
“The cathode (optimistic electrode) is coated with ultra-high nickel materials with the anode (destructive) being a brand new era of high-specific vitality composite silicon carbon materials,” Andrews noticed, with a “patented self-developed nano-scale” electrolyte to finish the image.
“Moreover, the electrolyte makes use of dry stable layer built-in molding with the resultant battery having diminished inside resistance that means ultra-fast charging is feasible,” he added.
Automobile Information China added a cautionary observe to the article, during which an unattributed editor acknowledged: “We are going to clearly have to attend till April 8 for extra particulars however the truth that there’s at the moment no MIIT itemizing for a variant of the IM L6 geared up with the battery might point out manufacturing continues to be a while off.”
“IM declare that the stable state battery is supposed to have a excessive vitality density however the important thing shall be how heavy the battery really is on condition that at 130 kWh the capability is kind of excessive. Success can also be depending on how a lot it’ll value to provide the battery and whether or not the automotive will be offered at a value which makes it worthwhile to buy,” the editor continued.
The Semi-Strong Resolution
Fascinating! Semi-solid state batteries will be accommodated by current EV battery manufacturing traces, which is one purpose why auto business observers are coalescing across the view that semi-solid expertise is readier to roll than solid-state expertise.
The Israeli EV battery startup StoreDot is amongst these pitching semi-solid expertise. Again in 2022, StoreDot CTO Daniel Aronov posted a long-form article explaining the corporate’s resolution to focus on semi-solid technology for ultra-fast charging right here and now, with all-solid state batteries someplace off sooner or later.
“The answer lies within the mixture of the benefits of solid state electrolyte (akin to catholyte and anolyte), whereas sustaining a small liquid or gel type of electrolyte that permits for a greater circulate of the ions between the cathode and anode, and mitigates the vital concern of solid-to-solid interface that in any other case holds too excessive of resistance,” he concluded.
Nonetheless, hope springs everlasting, and new developments are cropping up virtually by the minute. Within the newest information, the EU’s multi-agency mission HELENA reached a milestone for its new solid-state EV battery sporting a halide electrolyte with a lithium steel anode and a nickel-manganese-cobalt cathode.
