RIKEN team develops high-performance lithium-iodine battery system with higher energy density than conventional Li-ion

Green Car Congress

The reversible redox reaction without the formation of resistive solid products promotes rechargeability, demonstrating 100 cycles with negligible capacity fading. The Li-I 2 batteries showed high energy density and excellent recharge ability. Energy density was ~0.35 The specific energy density (~0.33

24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Co-founded by MIT’s Dr. Yet-Ming Chiang, 24M’s Chief Scientist, the company is leveraging existing, preferred energy storage chemistry but using a new cell design with semi-solid (a mixture of solid and liquid phases) thick electrodes and manufacturing innovations to deliver what it says will be up to a 50% reduction in current Li-ion costs.

DOE releases SBIR/STTR FY16 Phase 1 Release 2 topics; hydrogen, electric vehicles, more efficient combustion engines; biogas-to-fuels

Green Car Congress

The first hydrogen TTO is focused on durable, high activity electrocatalyst with low platinum content and low cost for polymer electrolyte membrane fuel cell applications. Conventional polymer electrolyte membrane (PEM) fuel cell technology requires high content of platinum electrocatalyst, which raises manufacturing costs.

Technical review outlines challenges for both batteries and fuel cells as basis for electric vehicles

Green Car Congress

In some studies it has been noted that the adequate BEV range perceived by the customer could be lower if the recharging time would be sufficiently short. For a 100 mile-range BEV requiring ≈21 kWh net , complete recharge could be accomplished within ≈60 min. can be realized at low cost, the authors suggest. kgH 2 /min.
