U Texas team develops cobalt-free high-energy lithium-ion battery

Green Car Congress

More nickel in a battery means it can store more energy. Ni NMA outperforms both NMC and NCA and only slightly trails NMCAM and a commercial cathode after 1000 deep cycles. Typically, increased energy density leads to trade-offs, such as a shorter cycle life. However, the researchers said they’ve overcome the short cycle life and poor rate capability problems through finding an optimal combination of metals and ensuring an even distribution of their ions.

Bosch Passes 1M Mark for Start-Stop Systems

Green Car Congress

In the New European Driving Cycle (NEDC), start-stop systems reduce fuel consumption, and thus CO 2 emissions, by up to 5%. In the NEDC urban cycle, the saving is as much as 8%. This ensures that the engine is only stopped if the battery has stored enough energy to start the engine again quickly. The system is rounded off by a crankshaft sensor, sensors on the pedals, and a deep-cycle resistant battery.

Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Advanced lead-based batteries (AGM and EFB technologies) are installed to meet extra requirements in start-stop and basic- micro-hybrid vehicles, due to their increased charge recoverability and higher deep-cycle resistance. Hybrid vehicles , including advanced micro-hybrid, mild-hybrid and full-hybrid vehicles rely on the battery to play a more active role, with the energy stored from braking used to boost the vehicle’s acceleration.

For example, they note, to regulate frequency, the energy storage capacity may not need to be long-lasting—minutes can be sufficient—but it must have a long cycle life because the system is likely to encounter multiple daily discharge events. This type of application requires high round-trip energy efficiency and a long deep-cycle life, along with low operation and maintenance costs. Among the most important factors are capital cost and life-cycle cost.

On the New European Driving Cycle (NEDC), start-stop systems reduce fuel consumption and CO2 emissions by up to 5 per cent, whilst the saving is as much as 8 per cent on the NEDC urban cycle. This ensures that the engine is only stopped if the battery has stored enough energy to start the engine again quickly. The system also features sensors on the crankshaft and pedals, as well as a deep-cycle resistant battery.
