Abstract
A composite material tape and a lithium secondary battery using the same are provided. The composite material tape includes an organic base and at least one inorganic element dispersed within the organic base. The composite material tapes of the present invention exhibit improved Insulative and heat-resistant characteristics.
Claims7
A lithium secondary battery comprising:
- an electrode assembly comprising:
- a first electrode plate having a first electrode collector, the first electrode collector comprising a coated region and an uncoated region;
- a second electrode plate having a second electrode collector, the second electrode collector comprising a coated region and an uncoated region, and
- a separator positioned between the first and second electrode plates;
- a first electrode tab directly attached to a first surface of the uncoated region of the first electrode collector;
- a second electrode tab directly attached to a second surface of the uncoated region of the second electrode collector;
- a first adiabatic plate attached only to a second surface of the uncoated region directly opposite to the first surface of the first electrode collector and directly contacting the separator,
- wherein the first electrode tab and the coated region of the first electrode plate is entirely spaced from the first adiabatic plate,
- wherein the first adiabatic plate does not cover the first electrode tab,
- wherein a width of the first adiabatic plate is relatively smaller than a width of the uncoated region,
- wherein the first adiabatic plate comprises a composite material tape,
- wherein the composite material tape comprises an organic base and at least one inorganic element dispersed in the organic base,
- the composite material tape comprises from about 20 to about 80 weight or volume percent inorganic elements, and
- wherein the inorganic elements support the composite material tape when the organic base melts.
