We’ve extended the technology front with two new flagship next generation lithium-ion cells from V4Smart!
⚡ V21700 HP-5X
– 299 Wh/kg energy density
– 2.63 kW/kg power density
⚡ V21700 (U)UHP-3X
– 192 Wh/kg energy density
– 5.56 kW/kg power density
You can also check out the key features of the cells via the V4Smart website or contact us directly via info@batemo.de.

The Tenpower 50XG is another serious powerhouse nestled amongst the tabless cells in the Batemo Cell Explorer 💥

🔌Energy Density (volumetric): 734 Wh/l
💡Power Density (volumetric): 6.95 kW/l
🔋Capacity (C/10): 5.12 Ah
⚡Current range: -30C to 4C

The 50XG shows strong high-power capability, and like all high-performance cells, the sustainable operating window is set by heat management. Short bursts? No problem. Continuous high power? That’s where thermal design makes or breaks the system.

In power tool applications, battery cells must deliver high discharge currents, maintain thermal stability, and provide reliable runtime under demanding operating conditions. Selecting the right cell is crucial to meeting these performance requirements.
Cells like the Molicel P50B, Highstar 50PS(B), BAK 45D(B), Tempower 40XG, and Ampace JP30-PI(C), reflect the innovation happening in this space.
We highlight some of the nuances in our full post on LinkedIn, using insights from the Batemo Cell Explorer.

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.
