Sponsored by OCSiAl Group Li-ion batteries represent the most dynamic and fastest growing battery market, with total sales of $10 billion in 2015 [i]. Historically, the primary challenge for battery manufacturers has been the constant demand for greater energy density, both volumetric and gravimetric. Li-ion’s dramatic rise is in large part due to solving this challenge more… Read more »

Panasonic shifts focus to automotive tech
The coming restructuring of the auto industry will yield winners and losers. New opportunities will open up for battery-makers and copper producers, but the hottest sector of all may be “auto tech,” which includes not only powertrain electronics such as motor controllers, inverters and chargers, but also self-driving hardware and software, and customer-facing components such… Read more »
Researchers make a major advance in silicon anodes
Current electrode materials such as graphite are able to stably adsorb only a limited number of lithium ions, an inconvenient truth that restricts capacity. That’s why researchers around the world are investigating semiconductor materials such as silicon as alternative electrodes. Bulk silicon is able to accommodate enormous quantities of lithium, but the migration of the… Read more »
Cyber-security or cyber-resilience?
By Sam Abuelsamid, Senior Research Analyst – Navigant Research If you move, you will die. If you don’t move, you are already dead. There are countless variations on that theme but the gist is that life is full of risk and, sooner or later, it will get you. However, if you plan ahead and prepare,… Read more »
A closer look at wire bonding
Wire bonding technology – widely utilized in the microelectronics and power electronics industries since the 1970s – is finding its way into interesting new applications in the growing EV industry – in particular, battery connections. We’re quite certain that a few EVs are using wire-bonding technology for production battery pack connections, but Charged was unable… Read more »
Graphene cages could be the key to silicon anodes
Battery boffins are buzzing about silicon anodes, which could store up to 10 times more energy than today’s anodes. The catch is that silicon particles tend to swell and crack during cycling, and to react with the electrolyte in unwanted ways. Now a team from Stanford University and the Department of Energy’s SLAC National Accelerator… Read more »
Can Tanktwo redefine the battery pack with big data?
A Finnish-American start-up with ambitious goals wants to change how we think about batteries. The concept of an EV that supports the quick removal and replacement of a discharged battery pack was all the rage about 5 years ago. Since then, however, various systems have been attempted and subsequently abandoned by companies like BetterPlace, Renault,… Read more »
Is String Cell battery technology the future for EVs?
When it comes to finding a way to charge EVs more quickly, human ingenuity has come up with some pretty wide-ranging solutions, from battery-swapping to flow batteries that store energy in tanks of liquid electrolyte. The latest innovative idea comes from startup Tanktwo, and is called a String Battery. Tanktwo’s system replaces a vehicle’s battery pack with a container filled… Read more »
EVs, renewables & energy storage: The unstoppable trio of energy’s future
The ripples of disruption: Q&A with Mike Calise The concept of disruption is often discussed in the fields of semiconductors, the internet, data, computers and software. But what about the energy industry? The world has been largely generating and consuming energy the same way for over a century. Charged talked to Mike Calise, Head of Electric… Read more »
Automakers offer free hydrogen – but not for the reason you think
Not ready to buy a hydrogen fuel cell vehicle yet? Would free fuel tip the balance? Both Hyundai and Toyota are offering free hydrogen fuel with their FCVs. According to Toyota, buyers of the new Mirai sedan will receive “complimentary hydrogen fuel for up to three years.” While free fuel may indeed be an enticement… Read more »
