Samsung SDI engineered new stacking method for smartphone batteries
Samsung SDI has invented a new battery production process for small batteries. It is a stacking technology that stacks the internal material of the battery layer by layer like a staircase. This also helps to retain the battery power for a longer duration and also reduces its overheating.
According to news firm ‘TheElec‘, Samsung SDI has decided to introduce a stacking type production process to the small pouch-type battery, at the production line at its Cheonan plant. This is done by remodeling the production line called M-line.
Until now, only the winding-type batteries are produced by weaving a battery material such as cathode material, separator, and anode material. This is the first time that Samsung SDI is preparing to produce small batteries in the stacking process.

The exact amount of investment was not disclosed but is expected to be around 100 billion won, and more can also be required to renovate all the production lines.
In the recent time, only Samsung SDI has developed a new separate pilot line and on the other hand, the statement of industry officials also verify the same, having said that “the Chinese pilot line is for mass production testing, and we plan to utilize the domestic Cheonan plant for the production line.”
Samsung SDI found that by using this stacking process, energy density can be increased by more than 10%. So instead of notching equipment to make tabs of anode and cathode materials, stacking equipment is needed to properly stack these materials.
Why this stacking process is used?
Stacking has been used first for the fifth-generation electric vehicle batteries. The process is adopted for making the smartphone batteries because it increases the energy density of the battery, and provides increased battery mileage at a reduced cost. Though it’s very tough to utilize each and every space inside the battery this process can help a lot.
Cylindrical batteries also provide the performance but the regular charging and discharging of the battery reduces the energy-carrying capability of the material. Which results in a swollen battery, and this is all due to deterioration of the material inside the battery.
Every month, Samsung makes changes to its software update plan, with some devices being added, some being demoted, and some being removed. We are in October 2024, and Samsung has shared its updated software update plan list for Galaxy devices.
October 2024 update plan shows that the company will provide Monthly Security Updates for 35 Galaxy devices and Quarterly Security Updates for 76 devices. Additionally, 29 devices will receive Biannual Security Updates, which are less frequent but help to ensure that older devices remain secure and up to date.
Notably, the latest security patch includes Google updates based on the Android Security Bulletin, addressing 2 critical and 28 high-level vulnerabilities. One issue has already been resolved in prior updates, and two are not relevant to Galaxy devices.
Moreover, Samsung’s patches fix 12 specific vulnerabilities related to its devices and applications, including system and Knox services. Samsung Semiconductor also adds a fix for one high-level vulnerability to improve overall performance.
Below you can check the updated monthly, quarterly, and biannual plan for Samsung devices in October 2024.

- Consolidated Operating Profit: Approximately 9.1 trillion Korean won
Samsung’s flagship and foldable phones scored lower than expected sales. The company’s semiconductor business is already in crisis due to yield issues. Samsung is facing concerns in multiple ways leading it to a critical stage.
TSMC continues to widen the gap in the international foundry market. Its rivals in the memory chip market like SK Hynix are also giving fierce competition. Late entry into the cutting-edge AI memory semiconductor market also made things painful.
We’ve seen reports Samsung could be laying off employees in various countries. The company could cut its workforce and focus on growth further. DS Division could also see a major reshuffle to return to the pace of growth.
It’s 8th October 2024 and Samsung has updated the details of the latest security patch for its Galaxy devices on its scope page. It contains CVE and SVE items to improve the security and stability of the device to provide a better and more secure experience.
Samsung has already begun releasing the October 2024 security patch and Galaxy S24 FE is the first smartphone to receive it. The company will add more devices soon to this update list.
October 2024 security update includes patches from both Google and Samsung, addressing various vulnerabilities and exposures in the Android operating system and Samsung’s software.
The Google patches cover up to the Android Security Bulletin – October 2024 package, which contains 2 critical level and 28 high-level CVEs. However, 1 CVE has already resolved by previous updates from the company, and 2 are not relevant to Galaxy devices.
On the flip side, the Samsung patches include 12 Samsung Vulnerabilities and Exposures (SVE) items, which are specific to Samsung’s devices and applications. It fixes issues related to system service, Knox services, and more.
Not only this, Samsung Semiconductor also adds a fix for 1 high-level CVE to enhance the performance.
