Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-performance, hybrid sodium-ion battery that charges rapidly and offers impressive energy density.
This revolutionary prototype uses sodium (Na), a chemical element over 1000 times more abundant and cheaper than lithium (Li), the main component of conventional batteries.
Generally, sodium-ion batteries face constraints such as lower power output, limited storage properties, and extended charging times. The innovative battery design, led by Professor Jeung Ku Kang of the Department of Materials Science and Engineering at KAIST, combats existing limitations of sodium-ion batteries by integrating the anode materials used in traditional batteries with the cathodes used for supercapacitors into a hybrid system. The result reportedly delivers high storage capacity and rapid charge-discharge rates.
Multiple possibilities
Developing the hybrid battery hinged upon improving the energy storage rate of battery-type anodes and boosting the relatively low capacity of supercapacitor-type cathode materials.
The research team at KAIST made use of two distinct metal-organic frameworks to create an optimized synthesis of hybrid batteries, culminating in anode material with improved kinetics and a high-capacity cathode material.
The fully assembled hybrid sodium-ion energy storage device reportedly surpasses the energy density of commercial lithium-ion batteries and matches the power density characteristics of supercapacitors. Professor Kang says this new battery, with an energy density of 247 Wh/kg and a power density of 34,748 W/kg, could be used across a range industries, including electric vehicles, smart electronics and aerospace technologies.
The findings of this research, co-authored by KAIST doctoral candidates Jong Hui Choi and Dong Won Kim, were published in the international journal Energy Storage Materials with the catchy title of “Low-crystallinity conductive multivalence iron sulfide-embedded S-doped anode and high-surface-area O-doped cathode of 3D porous N-rich graphitic carbon frameworks for high-performance sodium-ion hybrid energy storages.”

On Monday, further charges were added to the slaying of a former Southern California police chief as he rode his bicycle on a roadway in Las Vegas. The slaying was caught on tape, and the prosecutors decided to add the new counts.
At least three hit-and-run accidents took place on the morning of August 14, according to the police, including the collision that the police believe was intentionally caused to take the life of Andreas “Andy” Probst, who was 64 years old. Tuesday is the day when the two young people, who are now 18 and 16, are expected to show up in court. The identities of the adolescents will not be disclosed by the Associated Press due to the fact that they are still minors. In 2009, Probst resigned from his position as police chief of Bell, California, which is a suburb of Los Angeles.
According to Clark County District Attorney Steve Wolfson, the young man, who is just 18 years old, has been charged with attempted murder, battery with a dangerous weapon, fleeing the scene of an accident, and possession of a stolen vehicle. All of these charges stem from an incident in which the victim was attacked with a firearm.
When the accusation of assault with a weapon was added, the suspect, who was just 16 years old at the time, was already charged with murder and attempted murder.
David Westbrook, the public defender representing the senior defendant, chose not to comment on the latest charges. According to what Westbrook has indicated, his client was just 17 years old when he was taken into custody a month ago.
On Friday, the younger adolescent made their initial appearance in court without the representation of an attorney. When he appears in court on Tuesday, he will most likely have an attorney appointed to defend him.
“The behavior that was exhibited by (the) defendants… is outrageous and cannot be tolerated in this community,” Wolfson said in a statement. “The defendants”
These young offenders are not eligible for the death sentence under any circumstances. According to the laws of Nevada, the maximum sentence for a person who is found guilty of murdering someone before they reached 18 is anything from 20 years to life in state prison.
According to the police, the juveniles were operating a stolen Hyundai sedan that had earlier hit and left the scene after hitting with a biker who was 72 years old, a Toyota Corolla, and then Probst.
The video was shot from the perspective of the front passenger seat, and it shows the young people laughing and chatting just before to the moment when the automobile started moving toward Probst and collided with the bike. After having his body crushed into the car’s hood and windshield, Probst can be seen laying on the ground near to the curb as the camera pans out to see this.
On the same day, the 18-year-old was brought into custody by law enforcement. The police stated that they were able to discover about the video’s dissemination at a high school the previous week, and they issued an announcement looking for the video’s producer, who is 16 years old.
The bribery and corruption charges against Texas Attorney General Ken Paxton were dropped because of his friendship with real estate developer Nate Paul. The Texas Senate has cleared Attorney General Ken Paxton of all charges of corruption and unfitness for office that were brought against him.
Even though impeachment has backing from both parties, the number of votes needed to convict on each charge did not reach 21. All 12 Democrats and two Republicans, Robert Nichols and Kelly Hancock, voted to convict on several charges.
The Texas Senate got together to vote on Saturday at 10:30 a.m. central time and was done just before 1 p.m.
“The truth won out today. “Mudslinging politicians and their powerful backers couldn’t hide the truth,” Paxton said in a statement thanking his fans after the decision came out. According to Paxton, the “weaponization” of impeachment is “immoral and corrupt,” has cost taxpayers millions of dollars, interfered with the work of the Office of the Attorney General, and left a dark and permanent stain on the Texas House.
“Now that this embarrassing process is over, I’ll go back to protecting our basic rights. “Thank you to everyone who has been there for us through this,” he said.
After the hearing was over, Texas Gov. Greg Abbott praised Paxton.
“The verdict is in. The Texas Constitution says that Attorney General Ken Paxton was given a fair hearing. Abbott said, “I look forward to continuing to work with the Attorney General to protect the border and keep the federal government from going too far into Texas.” The 30 senators on the panel, most of whom are Republicans, talked for about eight hours behind closed doors after the Senate was done talking. To convict Paxton on any of the 16 articles of impeachment that charge him of bribery, corruption, and being unfit for office, two-thirds of the votes had to be in favor.
The voting took time and was open to the public. Each part of the impeachment got its own vote. The Senate is made up of 19 Republicans and 12 Democrats. If all Democrats decided to convict Paxton, they would need nine Republicans to vote with them. They got at most two.
People said that Paxton used his power as a politician to help Nate Paul, a real estate developer. Opponents of Paxton have said that the attorney general took a bribe when he hired Paul.
During final remarks, Republican state Rep. Andrew Murr, one of the impeachment managers in the Texas House, said, “If we don’t stop public officials from abusing their power, no one can.” The lawyers for the joint group of lawmakers who are trying to get Paxton impeached finished their case on Wednesday. This was after a woman who was supposed to speak about a sexual affair with Paxton showed up at the trial unexpectedly but never took the stand.
The FBI was looking into Paul, who hired Laura Olson, and the affair was at the center of the case against him. One of the reasons for impeaching Paxton was that Paul’s decision to hire Olson was a bribe.
Paxton’s lawyers have said that the impeachment effort is an attempt by establishment Republicans to get rid of a proven conservative. They point to Paxton’s long history of challenging Democratic presidential administrations in high-profile court cases, which has earned him praise from former President Donald Trump and conservative hardliners.
Tony Buzbee, a lawyer for Paxton, said, “I think this is a political witch hunt.” “I would say that this trial has put on display for the whole country a fight between different groups within the Republican Party,” he said.
Paxton was also charged with making fake claims to banks back in June. Paxton was suspended from his job until the trial ended, so he did not have to be there. He only showed up once during closing statements since evidence started last week. Angela Paxton, a state senator, and his wife sat on the other side of the room. She had to be there for the whole trial, but she couldn’t participate in the discussion or vote on how her husband’s case turned out.
