Author Dr. Simon Madgwick of Nuvvon Inc. Since the Nuvvon post unveiling Solid State Silicon Anodes (1Ah Silicon NMC), the cells have been scaled up and further differentiated into 250Wh/kg Power cells versus 400Wh/kg Energy cells. Here is the Power cell with continuous 3C Charge / 5C Discharge full DOD – at point of posting 1014 cycles … Read more
Author: Sebastian Kawollek A look at this paper and how it compares to what we see in the field. Xu J, Li H, Hua S and Wang H (2025) Experimental investigation of grid storage modes effect on aging of LiFePO4 battery modules. Front. Energy Res. 13:1528691. Introduction: To investigate the degradation behavior of energy storage batteries … Read more
Where to start with the task of developing a lifecycle test procedure. Battery cell ageing is such a complex subject that it makes it difficult to know where to start. One of the first things to do is to break the problem into Calendar and Cycle Ageing. Now we know we are going to be … Read more
Is there a relationship between Cycle Life and Energy Density? This is a mix of chemistry, age, size and manufacturers. Hence a lot of other information mixed into this, but there is a trend. Adding trendlines might be generous, but what we can see is that low energy density cells range in cycle life from … Read more
