OSAKA -- China is increasing its presence in the race to develop replacements for the lithium-ion battery, a Nikkei analysis shows. A country-by-country tally of patents related to post-lithium-ion batteries over the past 10 years shows China in the lead, accounting for more than half of all patents.
The evaluation of patents for sodium-ion batteries, perhaps the biggest horse in the race, also shows China dominating Japan and the U.S., with Chinese companies expected to begin mass production of these batteries this year.
Japan and the U.S. are also rushing to develop inexpensive alternatives to resource-constrained batteries for their decarbonization efforts but lag behind China.
Nikkei requested the Mitsui & Co. Global Strategic Studies Institute to use the patent analysis tool from LexisNexis, a U.S.-based intellectual property information service. There were 9,862 patents in force as of December, a twelvefold increase over the past 10 years.
When companies and research institutes with active patents were counted by country, China ranked first with 5,486 patents, accounting for more than 50% of the total.
Japan, which had been No. 1 until 2015, was next with 1,192 patents, followed by the U.S.'s 719, South Korea's 595 and France's 128.
China also stands out in the ranking of patents by organization. It has seven institutions in the top 10, including the Chinese Academy of Sciences (CAS) and Contemporary Amperex Technology (CATL).
The Mitsui institute evaluated not only the number of patents but also the overall index, which takes "quality" into account. In LexisNexis' index, based on factors like the number of citations to other patents, China ranked first with 4,930 points. Second place went to the U.S. with 2,630 points. Japan, which had been in the top position until 2017, was in third with 2,260 points.
China is particularly strong in sodium-ion batteries, which are expected to unseat today's Li-ion batteries in the gadgets of tomorrow. Sodium is a plentiful resource and can reduce the use of scarce industrial materials like lithium. Although their capacity will be lower than that of lithium-ion batteries, they will cost 60% to 70% less.
CATL, the world's largest maker of automotive batteries, has announced plans to mass-produce and supply sodium-ion batteries for EVs in 2023. Other companies are also rushing to commercialize the technology.
In terms of patents related to sodium-ion batteries, China's overall index has increased 109-fold over the past 10 years, two to three times that of the U.S. and Japan.
We see China’s miserable technology attempts and raise with 21,235,364 woke idiots with underwater lesbian dance degrees and 1,253,362 trannie wierdos doing face dances on four year olds.
What a joke! Like China cares anything about patents where their 1/2 trillion dollars in IP theft every year!
Unless you find a way to make batteries from Hydrogen or Helium you won’t get anything lighter than Lithium.
What we need is to drill baby drill and mine baby mine and put in prison the government officials who try to limit our options. In a free market there's plenty of energy for all Americans to buy cheaply in whatever form they want to cool and heat their homes and however they want to drive (ICE or EV). Don't fall for the left in arguing over which energy sources are better. Always the argument should be getting the government out of the way so we can buy whatever we want.

MEANINGLESS, as we have far more Drag Queens working on advanced battery designs than they do...so nothing to worry about here.
I respectfully disagree. Hydrogen is light relative to lithium. Even if stored in a solid medium. The problem is the round trip for producing hydrogen through electrolysis, then getting power from it through a fuel cell, has a loss of at least 30% - 50%. With a battery the round trip loss of charging to discharging is 5% to 10%.
If the Dims keep doing their war on energy, I'd be interested in a hybrid BEV/HEV. With home solar you can charge your own battery (literally the only reason I have an EV is to give me some protection against the Dim's stupid war on energy). On the days I have excess solar power with nowhere useful for the power to go (home batteries and EV charged), I could run an electrolyzer to generate hydrogen for the next long trip. When driving around I could get the miles from the Battery of the BEV, but in long distances between chargers (or to bypass chargers if the Dims keep making power too expensive) I could run on hydrogen.
“In 2021 researchers from China tried layered structure MoS
2 as a new type of anode for sodium-ion batteries. A dissolution-recrystallization process densely assembled carbon layer-coated MoS2 nanosheets onto the surface of polyimide-derived N-doped carbon nanotubes. This kind of C-MoS2/NCNTs anode can store 348 mAh/g at 2 A/g, with a cycling stability of 82% capacity after 400 cycles at 1 A/g.”

“Sodium-ion batteries can use aqueous and non-aqueous electrolytes. The limited electrochemical stability window of water results in lower voltages and limited energy densities. Non-aqueous carbonate ester polar aprotic solvents extend the voltage range. These include ethylene carbonate, dimethyl carbonate, diethyl carbonate, and propylene carbonate. The most widely used non-aqueous electrolyte uses sodium hexafluorophosphate as the salt dissolved in a mixture of these solvents. Additionally, electrolyte additives can improve performance metrics.”
The Wikipedia article has a sodium-ion/lithium-ion/lead–acid battery comparision table.

Well, okay. But the United States is leading in the pronoun race (em, cirself, etc.).
By some accounts we now have more than 70 different ones.
Try to top that, China.
The Chinese are determined to be number one, and will be.
In the USA, politicians are most concerned about how to slice up the economic pie instead of baking more pies.

We spend 16% of GNP on health care, they spend 6%. We are lawyered to the hilt, they obviously are not, also in the GNP. We have 100M people plus fully living off the government, they likely have less, even with a population 4 times our size. They build and sell twice as many cars as us, multiple times more concrete poured, same with steel, electricity, and just about everything else measurable.
...bottom line, they’ve long-since passed us, but they’re happy to not brag about it, since, if they did, we might have done something SMART, like getting with Russia to take them on.
More pollution but no response form the eco crazies
...my daughter, a full time mother of 2 and full time CPA/Controller for a large restaurant chain won’t drive her and her husband’s Tesla across the street. He, an attorney, rightfully is stuck with driving what was his idea in the first place.
I like Musk and I wish his car was a better product but it is just not.
I wouldn’t believe anything in a Chinese patent application. Currently the world is flooded with scientific papers with Chinese authors that have faulty, biased, or even no research supporting them. The system of power review has been gamed.
The other thing is who thinks using sodium in batteries is a great idea. Lithium batteries burn, sodium reacts with water by exploding, violently.
