1. Understand LG Energy Solution in 30 seconds and its position with solid-state batteries
LG Energy SolutionEnglish Name LG ENERGY SOLUTION, LTD.
Yongsan-guYeouido-daero 108 Parc.1 Tower
split from LG Chemlisted on the Korean market in January 2022
anodelessthe method has been publicly announced by itself, which is rare
Companies working on solid-state batteriesAutomotive manufacturers, battery manufacturers, and startupsare divided into three types. LG Energy Solution isbattery manufacturerand also The business department is a pure battery specialist with only one solution under ‘Energy Solutions’.. fact. Unlike automobile manufacturers who have an exit point of ‘installing in their own cars’, they do not have such an outlet. Therefore, even solid-state batteries arenot sold unless adopted by someone.。
Another important point to read this company is thatsolid-state batteries are only one of the four pillars of next-generation technologies.. Their official website refers to them asNa-ion battery (commercialization plan 2027), bipolar battery (same in 2028), solid-state battery (same in 2029), lithium-sulfur battery (same in 2029)The four are listed here fact. The company is not fully committed to solid-state batteries.

Action plan for the second half of 2026Pilot line for solid-state batteries with dry electrode processThis sentence is, despite its brevity, it contains a significant amount of information fact. The electrodes of current liquid lithium-ion batteries are made by dispersing the active material powder in a solvent to form a slurry, and then coating it onto a metal foil.Dry the solventThis process is used to make. However, in all-solid-state batteries, it is known that this solvent damages sulfide-based solid electrolytes.
Dry electrodes are,Form the electrode by shaping powder without using any solventThis is the method. It does not require a drying oven, so the equipment is small and energy is not used. In other words, this company manufactures solid-state batteries‘Paint and dry’ to ‘Press in powder form’ changing the processThis means. It is a script that carries over the experience of polishing dry electrodes for liquid batteries directly to all-solid-state batteries. Unconfirmed / Future。
6. Previous Efforts

| July 2026 | The action plan for the second half of 2026 in the financial report explanation‘Prepare a pilot line for all-solid-state batteries using dry electrode processes’and it states | At this point, the pilot line is not yet operational |
7. Future Plans
The company as a whole has announced that it aims to double its sales by 2028 compared to 2023 (337 trillion won)with a five-year goal. Unconfirmed / FutureThe breakdown of this target and how much it includes solid-state batteries is not specified.
None of the following are mentioned in the annual report, interim report, official website, or financial statement explanations: Unconfirmed / Future。
solid-state batteryLocation and operating period of the pilot line／Mass production factory／production capacity (GWh)／ investment amount／Customer supply contract／Price／Numerical target for energy density. and especiallyCustomers who have not been publicly announcedPoints are important. Existing joint ventures (with GM for Ultium Cells, with Stellantis for NextStar Energy, with Honda for L-H Battery, and with Hyundai for HLI Green Power)All are for liquid cell batteriesand not for solid-state batteries.
8. What does this company aim to achieve with solid-state batteries?
This part includes information that the company has not directly stated.Inferred from primary sources within the scope of what can be read.Along with the basis, I will write it down.
| What can be read | primary information | Classification |
|---|---|---|
| solid-state batteries areAmong the four pillars of the next generation, the slowest oneas it is positioned | The commercialization plan years for the official website are as follows: Sodium 2027 → Bipolar 2028 → All-solid 2029 → Lithium Sulfur 2029 in that order | fact |
| The technology that comes out first will earn money, and solid-state batteries will be placed behinddesigned | The year with a mid-term target of double sales in 2028 is before the commercialization year of solid-state batteries (2029) | speculation |
| The exit for solid-state batteries isIt’s not just EVs | The official website lists the uses as ‘high-performance premium EVs, electric ships, and ESS’, and in InterBattery 2026, humanoid robots and UAM are also mentioned | fact |
| Strive to differentiate in the manufacturing processStrategy | The text specifically states that it is ‘written as if it were a pilot line applying the dry electrode process’ | speculation |
| The method was quickly announcedto gain momentum for the adoption review | Publishing specifications such as ‘sulfide-based, anodeless, less than 20 minutes fast charging’ on its own website before customers decide | speculation |
This company is about full-solid-state batteries“It calls itself the ‘sulfide system’ method” fact. This is actually quite rare. Toyota does not explicitly state its electrolyte system in 20-F, and Samsung SDI also only writes ‘its own solid electrolyte’ in its official release. If it were to reveal the method, it would be read by competitors as well as material manufacturers.
Nevertheless, writing it isbecause the reader is not a competitor but a customerand this article will be read. For battery manufacturers, solid-state batteries are “adopted and become a business.” Automobile manufacturers want to know the method, charging time, and safety prospects when choosing batteries at an early stage. Publishing specifications in advance is risky when no customer has been decided yet. Actions to be taken to be included in the table for consideration and adoption.It is natural to see it this way Unconfirmed / Future。
9. Mapping of solid-state battery collaborations
10. Technology Approach Used
LG Energy Solution is exploring the method of solid-state batteriesThe few companies explicitly stated on our official website. fact。
| Item | The content that has been made public. |
|---|---|
| System of solid electrolytes | sulfide-based. Cited high energy density, safety, and excellent high-temperature durability |
| Negative electrode | Anodeless (without cathode) designensures energy density. However, in the medium to long-term strategy for October 2024also offers products with graphite-based anodesas planned |
| charging | taking advantage ofless than 20 minutes ultra-fast charging |
| manufacturing process | applied to the pilot linedry electrode processis described |
| intended use | high-performance premium EVs, electric ships, ESS. InterBattery 2026 will also include humanoid robots and UAM |
| effectiveness in the system | safety and high-temperature durability bySimplify the thermal management system on the pack sideand explained |
What is often overlooked in the official site’s explanation is,Simplify thermal management at the system levelThis sentence says fact The current EV battery packs have cooling plates, coolant pipes, insulation materials, and heat barriers to prevent heat from spreading to adjacent cells, etc., Components that are not batterieswhich consume a considerable amount of weight and volume.
Even if the energy density per cell increases slightly, it is often offset by the overall pack. On the other hand, cells that are strong against high temperatures and do not easily experience thermal runaway can reduce these components. Therefore, this company’s argument is not about ‘cells being good’, butabout ‘the pack becoming lighter and cheaper’which directly affects the gains and losses for automobile manufacturers. The choice of anodeless design and sulfide system also needs to be read together with thisadvantage from the perspective of the packand should be considered as a whole Unconfirmed / Future。
11. The risks this company faces
| Risks | Content | Classification |
|---|---|---|
| All-solid-state battery customers are zero | As a battery manufacturer, it will only become a business when adopted, but neither the supplier nor the supply contract has been disclosed | Unconfirmed / Future |
| The target year is later than that of competitors | The commercialization plan is for 2029. There are also companies in the same Korean battery manufacturer that have set 2027 as their target year. | fact |
| There is still no pilot line | In the action plan for the second half of 2026, it is at the ‘preparation’ stage. There is no public record of having gone through a trial production run | fact |
| The revenue from the main business is unstable | Revenue has decreased from 337.455 trillion won in 2023 to 236.718 trillion won in 2025. In the first half of 2026, there was a business loss of 9.45 billion won | fact |
| Four next-generation technologies are competing internally | These include sodium, bipolar, all-solid-state, and lithium-sulfur, and resource allocation is not visible from the outside | speculation |
| An additional uncertainty with dry electrode | In addition to the all-solid-state battery itself, the manufacturing process also adopts a new method. Two novelties come together at the same time | speculation |
