Wildcat’s new copper fluoride cathode material offers 2.5x more capacity than today’s battery tech

The current generation of lithium-ion battery materials is quickly approaching its theoretical limit. In commercial layered oxide cathodes, like the popular nickel-manganese-cobalt (NMC), there is only one lithium ion for every metal. So, the most energy you could possibly store with those materials is one full lithium in and out, or about 300 mAh per… Read more »

The battery industry insiders: Q&A with the Bitrode Corporation

In many ways, the Bitrode Corporation has the ultimate inside scoop on the battery industry. Along with its parent company, Sovema, and sister division, Solith, the group has its hands all over battery development, manufacturing and testing. The companies supply equipment and support to many of the biggest names in automotive-grade battery manufacturing. Acquired by… Read more »

Silicon rally: EnerG2’s new silicon battery anode material

It seems that every time the hottest new smartphone or tablet comes out, one of the biggest points of contention among users is its battery life. The demands put on the batteries run them down faster than users would like, and the OEMs can’t simply increase the batteries’ size while still hitting their targets for… Read more »

Quantifying battery risks and thermal safety

Exponent engineers on battery risks and thermal safety: If you can’t measure it, you can’t manage it. Any type of energy storage technology has some risk associated with the unanticipated release of stored energy. Failure of a pumped-hydro storage system, for example, can lead to flooding. Hydrocarbon fuels like gasoline, diesel or methane can ignite into flames…. Read more »

Porous Power’s new microporous membrane will boost Li-ion battery performance

Q&A with Bernard Perry of Porous Power Technologies. In 2006, Porous Power Technologies was formed around a new microporous membrane material designed specifically for use as a lithium-ion battery separator. At that time, most battery separator materials were originally intended for other applications and adapted when the lithium-ion market began to develop. The company’s founders saw an… Read more »

NETZSCH scales up battery testing

When a battery technology firm develops a new material, typically the first step is to test its performance in a small-format battery package known as a coin cell. Coin cells are used directly in many consumer products, but they also serve as a stepping stone in large-battery research and development. Engineers begin the R&D process… Read more »

CalBattery’s new SiGr anode material hopes to break the battery bottleneck

California Lithium Battery took advantage of national and local government programs so it could focus on its revolutionary silicon-graphene anode material. Now with EV, electronics, and energy storage customers lining up, it hopes to break the battery bottleneck. When you think about a bottleneck, you think about constriction – something that moves in a particular… Read more »

Creatively displaying BMS data

Brian Gallagher has had a variety of engineering and management roles designing human machine interfaces (HMIs) in the biotech and automotive industries. Most recently, he is the cofounder of Andromeda Interfaces, which develops HMIs for many different industries. With the adoption of lithium-ion battery technology in electric vehicles, the role of battery management systems (BMS) has become… Read more »

oneDRIVE of a kind: KLD Energy’s new propulsion system

In August 2013, KLD Energy announced that it has received official UN and IEC certification for the battery pack solution of its proprietary electric drive system. The announcement marked the end of a five-year development effort and the beginning of high-volume production for the company’s ultra-efficient turnkey oneDRIVE propulsion system.  There are hundreds of different… Read more »

The new A123 looks a lot like the old A123: Q&A with Jeff Kessen

Start-ups are tough. The majority of them do not succeed, particularly those built around new technologies in burgeoning industries. Nowhere is this more evident than in the EV industry. Even with political support and government grants, many companies have miscalculated the market and the capital required to make it into the black.  In October 2012,… Read more »
