The Amprius SA03, featuring its cutting-edge patented SiCore™ anode, measured in with an energy density of 399 Wh/kg, matching almost exactly the 400 Wh/kg reported by the manufacturer.
The SA03 now holds the record for highest energy density across all cells in the Batemo Cell Explorer!
The SiCore™ cells from Amprius that leverage a multi-layered silicon anode architecture designed to overcome one of the biggest challenges in silicon-based cells: expansion stress.

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.
