Until now, we have devel­oped over 130 physical Li-ion cell models with an array of chemistries ranging from NMC, NCA, and LFP cathodes to graphite, silicon, and LTO anodes.
We’re thrilled to announce that we have now released our first physical sodium-ion (Na-ion) cell model into the Batemo Cell Model Library! 

At the forefront of Na-ion technology, the Farasis S35(B) pouch cell delivers an impres­sive energy density of 150 Wh/kg, nominal capacity of 34.3 Ah, and a power density of 807 W/kg making it one of the most advanced repre­sen­ta­tions of Na-ion cells under development for commer­cial use at the moment.

Intro­ducing the Toshiba SCiBTM 2.9Ah, a compact prismatic format cell and a game-changer for various applications, as it boasts an impres­sive 2.91 kW/kg power density.
The LTO chemistry in this SCiBTM (Super Charge ion Battery) cell offers excel­lent thermal stability and chemical safety, reducing the risk of overheating and fire hazards - an essen­tial charac­ter­istic for electric mobility and drone applications, for example.
As reported by Toshiba, the 2.9Ah cell can be charged from 0 to over 80% SOC in one minute. Designed for endurance, it also maintains over 80% of its initial capacity even after 40,000 cycles at high temper­a­tures and C-rates. This ensures relia­bility and long-term perfor­mance without the degra­da­tion often seen in tradi­tional lithium-ion batteries (Source)

Given the urgent need for cells with ultra-low internal resis­tance for many appli­ca­tion scenarios such as eVTOLs, electric two-wheelers and portable storage, we just integrated two new 21700 cells that boost the technical level of cylin­drical cells by adopting the innov­a­tive design of tabless current collec­tion:
The INR2170-45D(B) from BAK’s full-tab 2170 cell series checks in at 248 Wh/kg and 2.12 kW/kg, while the EVE Energy 21700 40PL is designed towards even more power: With 233 Wh/kg and 2.35 kW/kg, the 40PL extends the technology front of 21700 cells in the Batemo Cell Explorer.

From high-energy to high-power, the following 5 freshly added cells contribute to the advance­ment of 18650 technology in terms of their energy density or power capabil­i­ties.
Far East Battery (FEB) 18650-3800mAh: Sitting at the peak of high energy cylin­drical cells with a gravi­metric energy density of 287 Wh/kg.
Other additions are the Tenpower INR18650-35HE and the DMEGC INR18650-30P, a more versa­tile cell. Lastly, the Molicel INR18650-P28B and -P30B show a high power density, which Molicel is well-known for.

The market in high perfor­mance 21700 cells is evolving at an incred­ible pace and the brand-new A-sample from V4Drive of their 21700HEP-5.X offers a glimpse into the future: Combining 261 Wh/kg with 2.1 kW/kg, it redefines the perfor­mance limits for 21700 cells and surpasses the previous techno­log­ical front of 21700 cells in the Batemo Cell Explorer.
It’s fasci­nating to witness how these break­throughs in technology pave the way for electri­fi­ca­tion, laying a crucial founda­tion for the energy transition.

The Ampace 4872A0 and the Melasta SLPBA842126HV may be on the smaller scale when it comes to pouch cells, but they are big in perfor­mance!
Pouch cells are widely recog­nized for their use in large-scale automo­tive and energy storage system (ESS) formats. However, applications with volume and weight limita­tions such as for power tools and motor­sports, actively use them too.
The combi­na­tion of high power and high energy capabil­i­ties allows pouch cells to surpass the technology front of 21700 and 18650 cells.

We are excited to announce three prismatic cells from estab­lished Chinese manufac­turers: The BYD C45F-302Ah cell with LFP chemistry as well as the CALB L221N113 and CALB L221N147A based on NMC. These cells target applications such as stationary storage, where relia­bility and safety are the most impor­tant KPIs.
Their place­ment in the Ragone plot are corre­lated with the cathode chemistries, with the C45F-302Ah being compa­rable to other LFP prismatic cells we measured.

We added two ultra-high-power battery cells to the Batemo Cell Explorer, the 26700 NCA GF and 26700 NCA GL both from A123 Systems.
These cells surpass all existing cells in terms of volumetric and gravi­metric power density and set a new bench­mark.
It is exciting what is possible with NCA chemistry for ultra high-power applications such as motor­sports and F1.
