http://www.greencarcongress.com/2014/05 ... -peng.htmlPå systemnivå når man 400 Wh/kg, ett 100 kWh batteri skulle då väga 250 kg.

Power Japan Plus says that its battery charges 20 times faster than lithium ion batteries; is rated for more than 3,000 cycles; and can slot directly into existing manufacturing processes, requiring no change to existing manufacturing lines
Varpå man förstås frågar sig, vad menas med 20x snabbare än dagens Li-Ion batterier ? Och 3000 cykler finns det redan batterier som klarar men här pratar man antagligen om vid 100% DOD och då är det rätt bra trots allt. Sen kan batteriet laddas/urladdas till 100% vilket vad jag vet inte något av dagens batterier klarar.
Energidensiteten är dock inte bättre än andra Li-Ion tekniker men lång livslängd tillsammans med 100% DOD kanske gör att man på systemnivå kanske ändå erhåller högre densitet än dagens. Tillverkning av batterier påbörjas senare detta år så då får man väl lite mer exakta siffror kan man tänka:

➢ High Performance – energy dense and charges 20 times faster than lithium ion batteries. It is also more powerful than other advanced batteries, operating above four volts.
➢ Cost Competitive – slots directly into existing manufacturing processes, requiring no change to existing manufacturing lines. Even more, the battery allows for consolidation of the supply chain, with only one active material — carbon. Additionally, manufacturing of the Ryden battery is under no threat of supply disruption or price spikes from rare metals, rare earth or heavy metals.
➢ Reliable – first ever high performance battery that meets consumer lifecycle demand, rated for more than 3,000 charge/discharge cycles.
➢ Safe – safest high performance battery chemistry ever developed. The Ryden battery eliminates the unstable active material used in other high performance batteries, greatly reducing fire and explosion hazard. Even more, the battery experiences minimal thermal change during operation, eliminating the threat of a thermal runaway. Finally, the Ryden battery can be 100 percent charged and discharged with no damage to the battery.
➢ Sustainable – contains no rare metals, rare earth metals or heavy metals, and is 100 percent recyclable, vastly improving the cradle-to-cradle sustainability of an advanced battery. Even further, Power Japan Plus is testing the Ryden battery with its organic Carbon Complex material, working towards the goal of producing the battery with all organic carbon in the future.
Verkar lovande, men som vanligt får man nog avvakta tills batterierna finns på marknaden.
