Fisker files patents on solid-state battery tech

Reborn automaker Fisker has filed patents for a new type of solid-state battery technology that it says could lead to much greater energy density and faster charging times. According to Fisker, current limitations of solid-state technology include low electrode current density, limited temperature ranges and non-scalable manufacturing processes. Other drawbacks include: low power and low… Read more »

A123 invests in solid-state battery tech firm Solid Power

A123 Systems has invested in Solid Power, a developer of solid-state battery technology. Solid Power’s tech combines a high-capacity cathode with a high-capacity lithium metal anode in combination with a high-ionic-conductivity solid separator. The battery materials are 100 percent inorganic, and possess no flammable or volatile components. Solid Power says its batteries provide two to… Read more »

MIT-led study suggests route to improving solid-state batteries

Replacing a liquid electrolyte with a solid electrolyte could offer major advantages for both safety and energy storage capacity, but so far, attempts to develop a practical solid-state cell have run into major obstacles. Liquid electrolytes can be flammable, and are also prone to the formation of dendrites -thin, fingerlike projections of metal that build… Read more »

FDK and Fujitsu develop novel cathode material for solid-state batteries

FDK and Fujitsu Laboratories have jointly developed lithium cobalt pyrophosphate (Li2CoP2O7) as a cathode material for solid-state lithium-ion batteries. The new material can operate at charge/discharge voltages of more than 5 V, which is beyond the limits of current lithium batteries. The energy of a battery is a function of its voltage and capacity, so an… Read more »

New electrolyte for solid-state batteries combines polymer and glass

Scientists at the DOE’s Lawrence Berkeley National Laboratory have developed a novel electrolyte that addresses many of the problems of solid electrolytes by combining the two primary types – polymer and glass. There are two kinds of solid electrolytes – polymer and glass or ceramic – and each has its own set of challenges. Polymer… Read more »

ARPA-E awards $6.6 million to two projects for solid-state battery electrolytes

The DOE’s Advanced Research Projects Agency – Energy (ARPA-E) has awarded $125 million to 41 energy-related R&D projects under its 2015 OPEN funding program. Two of these have to do with ceramic electrolytes for solid-state EV batteries. A consortium led by the University of Michigan won $3.5 million for a project called “Transitioning Advanced Ceramic… Read more »
