Abstract: Systems and methods which provide battery configurations for delivering high power while maintaining high energy density are described. Embodiments provide cylindrical batteries configured to deliver high energy density while having high power density at least in part through an electrode configuration disposing electrode material for the cathode and/or anode over an extended length of a longitudinal edge of the respective cathode or anode. An electrode configuration may provide for a continuous length of electrode material disposed along a longitudinal edge of at least one of the cathode or anode. Additionally or alternatively, an electrode configuration may provide for a plurality of electrode tabs of electrode material spaced out along a longitudinal edge of at least one of the anode or cathode.

Abstract: There is provided a lithium ion battery for use in a power tool. The lithium ion battery includes a carbon-based negative electrode containing a certain weight content of silicon-based material, a positive electrode including a lithium metal oxide containing nickel, and a non-flammable electrolyte placed between the negative electrode and the positive electrode. The weight content of silicon-based material in the negative electrode is no less than 5%. A composition of nickel of the lithium metal oxide is no less than the composition of other metals of the lithium metal oxide.

Abstract: Systems and methods which provide lithium-ion battery configurations with high energy density are disclosed. Embodiments provide lithium-ion batteries comprising an anode that includes 30 to 85 wt. % silicon, thereby facilitating high energy density and high N:P ratio for the lithium-ion batteries. The high N:P ratio further enables fast charging and low temperature charging capabilities of the lithium-ion batteries.
