Maxwell and SK to jointly develop ultracap/battery combo

Ultracapacitors (aka ultracaps or supercapacitors) are the toast of the town, thanks to their rapid charge and discharge capabilities, tolerance of extreme temperature conditions and long operational life. However, their killer application may be as partners with lithium-ion batteries, which offer higher energy density. Maxwell Technologies (Nasdaq: MXWL), a manufacturer of ultracapacitor-based energy storage products,… Read more »

Graphene supercapacitor packs basketball court-size surface area into one gram

Supercapacitors (aka ultracapacitors or ultracaps) represent one of the most exciting technologies in the EV world today. Because of their superior charge/discharge rates and long cycle life, they could make great companions to lithium-ion batteries, which offer higher energy density. Some brave souls predict that they could someday replace batteries altogether in some applications. Now… Read more »

New Linear Technology power manager and charger works with several battery chemistries
