LG Energy Solution (LGES) is all-in on prismatic battery cell production. LGES and other South Korean battery suppliers have noticed a significant increase in automakers’ demand for prismatic battery cells.
LG Energy Solution formed a task force to develop prismatic battery cells and is actively talking to customers about its new offering. Once the company starts producing prismatic batteries, LGES will be the first South Korean battery supplier to offer prismatic, cylindrical, and pouch-type options.
Fellow South Korean battery suppliers Samsung SDI and SK ON are also putting more effort into producing prismatic battery cells. SK On has already developed its prismatic form factor technology. While it prepares for mass production, SK On is actively talking to clients about prismatic cell manufacturing.
Samsung SDI has been the sole domestic supplier of prismatic cells in South Korea for some time, giving it an edge against LGES and SK On. As the EV market changes, the company is preparing for increased demand for its prismatic cells.
“Prismatic batteries will gradually widen its portion in the global EV market, as is shown by growing request for collaboration from EV manufacturers,” said Samsung SDI Executive Vice President Michael Son.
As old and new automakers delve deeper into electric vehicle production, more research and thought have gone into battery technology. Over the past few years, interest in prismatic batteries has increased. In 2019, Prismatic batteries made up a 19% market share in Europe.
As of 2023, prismatic cells accounted for 49% of batteries in the European market, beating pouch-type cells, which accounted for 35% market share. In 2019, pouch-type cells dominated the European market, holding 46% market share.
Meanwhile cylindrical batteries held a 35% market share in 2019, dropping to 16% in Europe by 2023, reported SNE Research. However, interest in cylindrical batteries could rise in the next few years.
LGES and Samsung SDI are nearing the mass production of Tesla’s 4680 cell design. Samsung SDI aims to start mass production on the 46-series cylindrical battery by early 2025. LGES plans to begin 4680 cylindrical cell production in South Korea this month and expects to reach mass production by the end of 2024.

Trump’s auto tariffs spark concerns in Japan

Japan expressed concern over President Trump’s auto tariffs, citing inconsistencies with a 2019 bilateral trade deal signed with the U.S.
Prime Minister Shigeru Ishiba said Japan is committed to the 2019 agreement despite current concerns over President Trump’s new tariffs.
Trump’s tariffs impose a 25% duty on imported vehicles, effective April 3, 2025, and auto parts duties will be imposed in May. The 2019 U.S.-Japan trade deal, signed during Trump’s first term, reduced tariffs on U.S. farm goods and Japanese machine tools.
Then-Prime Minister Shinzo Abe secured assurances from Trump, stating, “Between President Trump and I, this has been firmly confirmed that no further, additional tariffs will imposed.”
The 2019 bilateral trade deal did not cover auto trade between the United States and Japan. However, at the time, Prime Minister Abe had received assurances from President Trump that the U.S. would not impose national security tariffs on Japanese car imports. As such, the deal avoided higher U.S. car duties.
According to Reuters, Japan faces Trump’s 24% tariff on its exports to the United States, which were paused until July. Trump’s 25% auto tariff and a 10% universal rate remain intact, impacting Japan’s car-heavy economy.
Ishiba addressed the issue in parliament, noting, “Japan has grave concern over the consistency” between the tariffs and the 2019 bilateral deal. “We will continue to convey our stance (to the U.S.) from this standpoint,” he added, clarifying that Japan has no plans to terminate the agreement. The deal excluded automobile trade and remains a cornerstone of bilateral relations.
Japan’s trade negotiator, Ryosei Akazawa, visited Washington last week to discuss trade issues, including non-tariff barriers and exchange rates. Finance Minister Katsunobu Kato is set to meet U.S. Treasury Secretary Scott Bessent this week to address currency concerns, signaling Japan’s proactive diplomacy.
Japan’s firm stance reflects its intent to protect its auto sector while navigating U.S. trade policies. As talks continue, the outcome could shape bilateral trade dynamics and influence Japan’s export strategy amid ongoing tariff uncertainties.

Elon Musk dubs lawsuit alleging false Tesla odometer readings “idiotic”
The lawsuit alleged that Tesla’s odometer readings use “predictive algorithms” instead of actual mileage driven.

Elon Musk has responded sharply to a lawsuit alleging that Tesla speeds up its vehicles’ odometers to avoid paying for warranty-covered repairs.
Musk’s comment about the lawsuit’s allegations were posted on social media platform X.
The Lawsuit’s Allegations
The proposed class-action lawsuit claimed that Tesla is speeding up its vehicles’ odometers so that they can fall out of warranty quicker. This system, the lawsuit alleged, allows Tesla to save a significant amount of money in repairs.
The lawsuit’s plaintiff is Los Angeles resident Nyree Hinton, who alleged that his 2020 Tesla Model Y’s odometer readings reflect energy consumption, driver behavior and “predictive algorithms” instead of actual mileage driven, as noted in a Reuters report.
Hinton claimed that based on other vehicles and driving history, his car was stating that he was driving 72 miles a day when he usually drove just 20 miles at most. Because of this, Hinton alleged that his basic warranty expired well ahead of schedule, resulting in him paying $10,000 for a suspension repair that he believes should have been covered by warranty.
“By tying warranty limits and lease mileage caps to inflated ‘odometer’ readings, Tesla increases repair revenue, reduces warranty obligations, and compels consumers to purchase extended warranties prematurely,” the lawsuit noted.
Elon Musk’s Response
Tesla and its legal team have fully denied all material allegations that were outlined in the proposed class-action lawsuit. In a comment to longtime FSD user @WholeMarsBlog on X, Tesla CEO Elon Musk also criticized the proposed class-action lawsuit. “This is idiotic,” the CEO wrote in a post on X.
Veteran EV owners have also stated on social media that the lawsuit’s claims were inaccurate since Tesla’s odometers do not, in any way, use predictive algorithms. Others also pointed out that repairs are not a major source of profit for Teslas because the company’s vehicles tend to last long without requiring maintenance or spare parts.

Bizarre Tesla Cybertruck attacker in South Korea arrested and detained
The man is also accused of assaulting several people and damaging other vehicles during the incident.

A man who attacked a Tesla Cybertruck in South Korea’s Gangnam district has been arrested and detained.
As per reports, the man is also accused of assaulting a person and damaging several other vehicles during the incident.
The Incident
As per authorities, the suspect, who is in his 30s and is dubbed “Mr. A” (suspect names are typically not disclosed in South Korea to protect privacy and prevent possible prejudice), allegedly assaulted a hotel employee on the morning of April 15.
Following the assault on the hotel employee, the suspect reportedly knocked over a delivery motorcycle. He then went over and kicked a Tesla Cybertruck that was owned by a nearby medical facility. One of the all-electric truck’s side mirrors was damaged due to the attack.
As per a News 1 Korea report, Mr. A has also been accused of kicking four BMW vehicles at a nearby auto shop. The BMWs’ passenger side doors were damaged by the suspect.
Charges and Arrest
As per the Seoul Gangnam Police Station in an announcement, an investigation into the incident is underway. The suspect was arrested on charges of special assault, property damage, and obstruction of business.
Authorities apprehended Mr. A in Seongnam, Gyeonggi Province, on April 18. An arrest warrant from the court was released the day after.
Cybertruck Attacks
The Tesla Cybertruck attack in South Korea is quite bizarre as the suspect assaulted both people and vehicles. The incident, if any, seems to be quite different from the attacks on Teslas that have been reported in the United States and Europe, which seemed to be political in nature and a response to CEO Elon Musk’s close relationship with President Donald Trump.
