Making TOGG hybrid (like Nissan e-power) should be on the table.

Here's the most efficient gasoline engine from Saudis against EV storm.

Achates Power to develop a three-cylinder opposed piston GCI engine with the aim of demonstrating 37 mpg in a Ford F-150. As a comparison, the production gasoline F-150 V6 3.5L engine delivers 27 mpg.


Achates 100km: 6.4liter

Ford V6 3.5 100km :8.7lt

İmagine as if Achates were used as electric generator so there is no transmission thus less fuel consumption.

Another Turkish EV startup with the aim of reaching mass-production by 2025. How credible are they?

They have a competitive price and are targeting a different segment than TOGG.

Evry has the following plans.
  • Start early deliveries of the Very EV in 2024 (pre-orders has begun and the vehicle has been approved for the Turkish market)
  • 10.000 unit production facility to open in 2025

Typical Turkish capitalist reflexes are in full effect, love it! With the way things are going, we'll have a bunch more brands by the 2030's.

The question on my mind is, when we'll be able to buy the Günsel B9?

We need to subsidize EVs and chargepoints much more (instead of giving credit left and right to construction companies) and put higher tariffs on Chinese EVs and Tesla. Lower segments should be subsidized more and tax breaks should be granted progressively based on production numbers and percentage spent on manufacturing and other productive investments for at least two companies.

I wait this for years too.

Why no news since 2020?

A "Very" stupid trademark to pick. Before you decide the name of your brand from a list of 20 candidates, GOOGLE them all. An unique good quality brand name should be as short as possbile and yet should return close to zero hits in google. Nowadays when you search "apple" in google, it only brings up "Apple Inc" not apples. But for 99% of the new startups that mix-up will be a deadly blow to brand. Good luck making your brand synonymous with the word "very". Chances are slim to none.

New solid state battery charges in minutes, lasts for thousands of cycles​


Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes.


Lithium metal batteries could offer far better energy density and much lower weight than lithium-ion technology thanks to the replacement of heavier graphite with lithium metal as anode. However, one of the biggest challenges in the design of these batteries is the formation of dendrites on the anode’s surface, causing the battery to rapidly degrade, short, and even catch fire.

Researchers at Harvard John A. Paulson SEAS have developed a new lithium metal battery that withstand at least 6,000 charging cycles and can be recharged in a matter of minutes.

Their research not only describes a new way to make solid state batteries with a lithium metal anode but also offers new understanding into the interface reaction between lithium and materials at the anode in these type of batteries.

“Lithium metal anode batteries are considered the holy grail of batteries because they have ten times the capacity of commercial graphite anodes and could drastically increase the driving distance of electric vehicles,” said Xin Li, Associate Professor of Materials Science at SEAS and senior author of the paper. “Our research is an important step toward more practical solid-state batteries for industrial and commercial applications.”

In 2021, Li and his team offered one way to deal with dendrites by designing a multilayer battery that sandwiched different materials of varying stabilities between the anode and cathode. This multilayer, multi-material design prevented the penetration of lithium dendrites not by stopping them altogether, but rather by controlling and containing them.

In the new research, Li and his team stop dendrites from forming by using micron-sized silicon particles in the anode to constrict the lithiation reaction and facilitate homogeneous plating of a thick layer of lithium metal.

In this design, when lithium ions move from the cathode to the anode during charging, the lithiation reaction is constricted at the shallow surface and the ions attach to the surface of the silicon particle but do not penetrate further.

“In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle,” said Li.

These coated particles create a homogenous surface across which the current density is evenly distributed, preventing the growth of dendrites. And, because plating and stripping can happen quickly on an even surface, the battery can recharge in only about 10 minutes.

The researchers built a postage stamp-sized pouch cell version of the battery, which is 10 to 20 times larger than the coin cell made in most university labs. The battery retained 80% of its capacity after 6,000 cycles, outperforming other pouch cell batteries on the market today, the reserchers reported in Fast cycling of lithium metal in solid-state batteries by constriction-susceptible anode materials published in nature materials.

The technology has been licensed through Harvard Office of Technology Development to Adden Energy, a Harvard spinoff company cofounded by Li and three Harvard alumni. The company has scaled up the technology to build a smart phone-sized pouch cell battery.

Li and his team also characterized the properties that allow silicon to constrict the diffusion of lithium to facilitate the dynamic process favoring homogeneous plating of thick lithium. They then defined a unique property descriptor to describe such a process and computed it for all known inorganic materials. In doing so, the team revealed dozens of other materials that could potentially yield similar performance.

“Previous research had found that other materials, including silver, could serve as good materials at the anode for solid state batteries,” said Li. “Our research explains one possible underlying mechanism of the process and provides a pathway to identify new materials for battery design.”
