A recent study has assessed the lifecycle environmental impact during the production and use phase of three battery types for plug-in hybrid (PHEV) and full performance battery electric vehicles (BEV). The study indicates that newer lithium-ion (Li-ion) technologies outperform current nickel-metal hydride (NiMH) batteries and identifies processes contributing to 13 environmental impacts

Researchers have shown that graphene paper can be used to construct flexible and rechargeable batteries, which may even perform better than non-flexible batteries. These might be used in a range of portable, bendable and rollable devices and could also help develop new energy generation technology, such as flexible solar cells.

A recent study has assessed some of the environmental impacts of the production of batteries used with low carbon systems, such as photovoltaic cells and wind turbines. The results indicate that lithium-based batteries have the most significant impact, in terms of metal depletion and greenhouse gas (GHG) emissions, but more complete data are needed on possible toxic impacts to conduct a full comparison between batteries.

Levels of toxic metals in batteries were not immediately reduced in line with new limits imposed by EU regulations, according to a survey from Germany. The study focuses on concentrations of toxic metals contained in batteries sold in Germany in 2010 and 2011, but its authors say the results are relevant to other EU countries.

Innovatively designed batteries offer a way for vehicles to move away from their dependence on fossil fuels. There has been little mass-market uptake of new battery design, however. In the last century, only four types of battery have been used: manganese oxide; lead acid; nickel; and lithium ion, which is a relative newcomer, introduced in 1991. To understand how innovation moves from research and development (R&D) to application and the mass market, scientists perform technology lifecycle (TLC) analyses, often focusing on R&D and basic research. This study adds an additional indicator — start-up companies — to explore the early phases of how batteries transition from science into industry.

State based full and empty control for rechargeable batteries that will assure a uniform battery empty condition, even in the presence of a load on the battery. A fuel gauge provides a prediction of the open circuit voltage of the battery, and when the predicted open circuit voltage of the battery reaches the predetermined open circuit voltage of an empty battery, the load is terminated, after which the battery will relax back to the predetermined open circuit voltage of an empty battery. A similar technique is disclosed for battery charging, allowing faster battery charging without overcharging. Preferably an RC battery model is used as the fuel gauge to provide the prediction, but as an alternative, a coulomb counter may be used to provide the prediction, with error correction between successive charge discharge cycles.

Systems and methods for in-vehicle charging of pallet jack batteries are provided. An example system allows using a power source of a host vehicle configured to provide power at voltage levels lower than the operating voltage of the pallet jack battery stack. The system may allow, for example, charging a 24 volts pallet jack battery stack from a 12 volts power source of the host vehicle. The system may further comprise an interconnecting circuit having a plurality of contactors electrically coupling the batteries in parallel for charging and serially for discharging. The system may further comprise a voltage monitoring circuit to detect whether the pallet jack is connected to the host vehicle power source for charging. Based on the detection, the voltage monitoring circuit may reconfigure the interconnecting circuit to electrically couple the pallet jack batteries in parallel.

The ceramic material provides a high conductivity pathway for lithium-ions, enhancing the properties of the less conductive polymeric material. The polymeric material provides flexibility, binding, and space-filling properties, mitigating the tendency of rigid ceramic materials to break or delaminate. The interface between the polymer and ceramic can be made to have a low ionic resistance through the use of additives and coatings.
