Samsung SDI’s latest target is to begin mass-producing its all-solid-state batteries in the second half of 2027. That is a company production goal—not a confirmed date for a Galaxy phone, electric vehicle or other consumer product using the battery.
What does “2027” mean?
Samsung SDI announced the second-half 2027 target in March 2026. It refers to the company’s planned start of mass production, not a promised retail launch or a guarantee that production will begin on schedule. Earlier Samsung SDI materials also pointed to 2027, but the March 2026 statement gives the more specific timing. Samsung SDI’s March 2026 announcement

The distinction matters: industrial production can begin before a battery appears in a product that consumers can buy. Samsung SDI has not named a phone or vehicle model, announced a consumer launch date, or provided production-volume details in the sources cited here.

A conventional lithium-ion battery uses a liquid electrolyte to move ions between its electrodes. An all-solid-state battery replaces that liquid with a solid electrolyte. Samsung SDI says this design can reduce fire risk and enable higher energy density; those are the company’s stated advantages, not independently validated results established here.

#1 Best Overall
- Semi-Solid-State Battery for Safer Travel Power: Semi-solid-state battery design helps deliver safer, more stable charging in hot, cold, and everyday travel conditions. This portable charger power bank is built for road trips, flights, camping, commuting, and daily carry when reliable backup power matters.
- 10,000mAh Power Bank, Slim Enough for Every Day: Get 10,000mAh power in an ultra-slim 0.57-inch body that weighs only 6.9 oz. This small portable charger slips easily into a pocket, purse, backpack, or carry-on, giving you dependable power without the bulky brick feel.
- 15W Wireless + 30W USB-C Fast Charging: Snap on for up to 15W magnetic wireless charging, or plug in for up to 30W USB-C fast charging when you need power fast. A flexible magnetic portable charger and power bank for iPhone 16, 15, 14, 13, and 12 series.
- Built for Flights, Hotels, Road Trips, and Long Days Out: TSA-friendly capacity makes this battery pack charger portable for air travel, vacations, theme parks, work trips, and power outages. Pass-through charging lets you charge your phone and power bank together overnight with one USB-C cable.
- Smart Display, Low-Current Mode & TORRASCare Support: The digital display shows remaining battery at a glance before you head out. Low-current mode supports earbuds, AirPods, and other small devices, while 18-month TORRASCare support gives you added confidence for daily use and travel.
Samsung SDI also describes the battery as using a proprietary solid-electrolyte material and an anode-less design intended to increase energy density. In a December 2024 article, the company reported an energy density of 900 Wh/L and said that figure was 40 percent higher than its then-current mass-produced prismatic batteries. These are Samsung SDI’s figures and comparison, not an independent test result or a claim about every solid-state battery.
How far along is development?
The project has moved beyond a concept announcement, with a pilot line and customer evaluation samples reported by Samsung SDI. The company says it launched its S-line pilot project in March 2022 and completed a 6,500-square-meter pilot line in 2023. Its 2025 sustainability report says prototype samples went to key customers in December 2023, followed by A-samples in the second half of 2024. Samsung SDI 2025 Sustainability Report

- SEMI-SOLID-STATE SAFETY, BUILT FOR TRAVEL: Semi-solid-state cells hold a fraction of the flammable liquid in ordinary lithium-ion and resist thermal failure. In internal testing, the cells were puncture, cut and drill tested with no fire. The aluminum housing is highly thermally conductive, helping draw heat away from the cells and dissipate it during charging. Under 100Wh, it's airline carry-on ready.
- ALL-DAY POWER, STILL POCKETABLE: A full 10,000mAh gives a typical iPhone roughly 1.5 to 2 charges - plenty for long travel days, events and back-to-back workdays without chasing an outlet. The dense semi-solid state design (a paired 5,000mAh + 5,000mAh layout) keeps the pack slim enough to slip into a jacket pocket or bag. The built-in lanyard doubles as a USB-C cable, so a charging cord is always attached - nothing extra to pack or lose.
- QI2-CERTIFIED 15W MAGNETIC CHARGING: A strong, precisely aligned magnet snaps onto iPhone 17, 16, 15, 14, 13 and 12 with precise alignment and a strong hold, so you can keep using your phone while it charges. As a Qi2-certified, MagSafe-compatible charger, the magnetic connection keeps the charger aligned while you scroll, text, or move.
- DUAL USB-C, UP TO 30W OUTPUT: Two USB-C ports let you charge several devices at once and deliver up to 30W of fast wired power for phones, earbuds and tablets. The same port also refills the 10K itself quickly, so it's ready for the next day. (Large tablets and laptops draw more and may only charge partially.)
- FULL-COLOR LCD DISPLAY: A crisp color screen shows exact battery percentage plus live input and output wattage, so you always know how much power is left and how fast each device is charging - no blinking LEDs to decode. It stays easy to read at a glance, whether you're commuting, at an event, on a shoot or working late.
Pilot production and samples are development milestones: they show work on the battery and evaluation with customers, but do not establish that mass production has begun or that products containing the battery are on sale.

What might use Samsung SDI’s battery?
Samsung SDI has described several potential applications, but has not confirmed a consumer product launch. Its March 2026 announcement introduced a pouch-type all-solid-state sample under development for physical-AI applications such as humanoid robots. The company has also discussed prismatic all-solid-state batteries for electric vehicles and the potential to broaden form factors and applications to robotics, aviation platforms and next-generation wearables.

- WORLD'S THINNEST SEMI-SOLID-STATE 5,000MAH: At just 6.8mm at its thinnest point, the Air is the slimmest semi-solid-state Qi2 power bank you can buy — the semi-solid-state design supports this slim form factor while helping the cells stay stable and reducing fire risk. It sits flush against your iPhone and slips into a pocket, slim bag or clutch. TechRadar Pro CES 2026 Picks Award Winner.
- SEMI-SOLID-STATE SAFETY, BUILT FOR TRAVEL: Unlike conventional lithium-ion banks with a flammable liquid electrolyte, SolidSafe Air's semi-solid-state cells sharply cut the liquid component — lowering risk at the cell level and staying stable under heat, stress and impact. It's not a circuit-only fix but a fundamental change in chemistry. At 18.5Wh, it's airline carry-on ready.
- 15W QI2 MAGNETIC + 20W USB-C: Qi2-certified, MagSafe-compatible magnetic charging snaps onto iPhone 17, 16, 15, 14, 13 and 12 with precise, secure alignment, while the USB-C port delivers up to 20W when you're in a hurry. The 5,000mAh cell gives a modern iPhone roughly one full top-up, and you can charge wired and wireless at the same time.
- TITANIUM SHELL, BUILT TO LAST: A titanium-reinforced shell resists dents and drops, and titanium's high thermal conductivity helps draw heat away from the cells and dissipate it at the surface during charging. It's premium protection that keeps the Air tough and travel-ready in a remarkably slim form.
- CCC CERTIFIED FOR TRAVEL: CCC certified for battery compliance and travel in China, with FCC, CE and UKCA listings for other regions. Built-in circuit safeguards cover overcharge, over-discharge, overcurrent and short circuits. Magnetic charging suits MagSafe iPhones or a thin compatible case; for Pixel and other Android phones, use a magnetic case or the 20W USB-C port.
Those examples describe development targets and possible uses, not confirmed orders, named customers or products scheduled for release. The 2027 target therefore should not be read as a promise of a 2027 Galaxy phone or retail EV with this battery.
Quick Recap
What to watch next
