Samsung SDI presents new high-capacity battery cell

Samsung SDI at Energy Storage Europe 2018

Samsung SDI was present at Energy Storage Europe 2018, Germany’s ESS Exhibition and revealed a new high-capacity battery cell.


The 111Ah ESS battery cell showcased by Samsung SDI at the conference has the feature of substantially increased capacity. The capacity of this ESS battery is enhanced while the size is maintained through material innovation, and thus significantly increased the energy density of the battery. Moreover, the strength of this battery is that it allows an easy product upgrade without having to modify its design.

Samsung SDI first unveiled its new high-capacity ESS product, E3 model, which 111Ah cell is used to enhance the energy density. E3 can store the same amount of energy with less number of cells, enabling the size of the ESS facility to be reduced. This feature will receive spotlights from the market because it means that it can save installation and management cost.


We see that Samsung SDI considers the 94 Ah battery cell to be its long cycle life product. Nothing that we didn’t know already since its specs show a very impressive cycle life.

Anyway, since the upcoming 120 Ah battery cell is aimed for electric cars, this – same sized – new high-capacity 111 Ah cell seems to designed for ESS (Energy Storage Systems) only. Nonetheless, if some automaker decides to use it for EV battery packs, it gets a 39,4 kWh (96 x 3,7 V x 111 Ah) battery.

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

    Thanks for this article,
    Based on SDI roadmap, the next cell after 120Ah will be 150Ah and 180Ah.
    It’s means 53.3kWh and 64kWh for a battery pack with 96 cells

    I made an article on a French forum with the image extracted from a technical report including the SDI / LG Chem / Panasonic roadmap.

    Below the link for this report :

      Thanks Chris,

      This technical report had the most accurate estimate to this time and also the outlook seems to be believable.

      By the way I am sceptical if this ATL-J1 (60Ah, 94Ah, 120Ah …) cell format will have shiny future in BEV batteries. From my perspective it is just too high with 126mm and so you need at least 150mm high battery box = you need huge SUVs for them. Even the VDA-PHEV2 format used by VW with 91mm height needs at least 120mm high battery box.

      sorry about last comment at wrong place.

    You are right, the main advantage of the prismatic cell is the reduction of the number of cell and the possibility to upgrade the capacity of the cell by changing only 96 cells.
    As on the SDI Roadmap the target is to keep the same dimensions of the cell, we can imagine upgrade the battery pack after few years (ex 60Ah -> 150Ah on BMW i3 1st gen).
    We know also that SDI propose also a pouch cell for EV (60Ah / 3.7V) as an alternative of LG Chem for the Audi e-tron.

    The pouch cell seems the favorite format for all next EV
    See below the link for a comparative sheets on the main electrics vehicles with the details of the battery pack :

    Or a 80kWh pack…
