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.
