Proper now SVOLT appears to be the one main battery cell maker that goals to supply an excellent various to the favored BYD Blade Battery, by introducing its personal lengthy prismatic cobalt-free battery cells for use in easy module-less battery packs.
The prototype of the second technology SVOLT L600 quick blade battery cell has the next specs:
- Mannequin: L600 (second gen)
- Capability: 196 Ah (first technology was 184 Ah)
- Voltage: 3,2 V
- Vitality: 627,2 Wh
- Gravimetric vitality density: 185 Wh/kg
- Volumetric vitality density: 430 Wh/L
- Chemistry: LFP (LiFePO4)
- Begin of manufacturing: Q3 2022
By adopting a 100s1p configuration (100 cells in collection), battery packs would have a capability of 62,72 kWh. I believe that 60 kWh is the candy spot for reasonably priced mainstream electrical automobiles.
Contemplating a GCTP (gravimetric cell-to-pack) ratio of 90 %, the gravimetric vitality density of a module-less battery pack ought to be round 176 Wh/kg.
Contemplating a VCTP (volumetric cell-to-pack) ratio of 60 %, the volumetric vitality density of a module-less battery pack ought to be round 258 Wh/L.
Proper now, the BYD Blade Battery solely reaches 150 Wh/kg on the pack degree.
Whereas the present L600 battery cell prototype reaches 185 Wh/kg, SVOLT goals to achieve 200 Wh/kg already subsequent 12 months, as we are able to see within the roadmap under. Subsequently, the second-generation L600 battery cell might be extra vitality dense by the point it enters into manufacturing in Q3 2022.
Now think about how well-liked could be a super-mini just like the Renault ZOE with a 60 kWh LFP battery if bought for a similar worth of a Clio, without having any authorities subsidies. Sadly Renault’s newest technique is to concentrate on NCM battery chemistry alone.
Thankfully, SVOLT already signed battery provide contracts with one other European carmaker (Stellantis), so the following technology of the Peugeot e-208, would possibly get such battery pack in a not so distant future.
If I used to be answerable for SVOLT I might attempt to put a 55-60 kWh battery in a BYD Dolphin simply to indicate off the prevalence of my battery expertise…
Anyway, by subsequent 12 months BYD will in all probability launch a extra vitality dense BYD Blade battery, so it might stay the perfect battery pack obtainable for electrical automobiles.
