Amazon's new Kindle e-reader set to be released next week will feature a rechargeable and protective case, according to the Wall Street Journal.

The new case allows the Kindle to be thinner, according to the report, and will extend battery life past what the standalone e-reader can provide. There's no word if the rechargeable and protective case will ship with the new Kindle or separately.

The report follows up word on Monday from CEO Jeff Bezos that Amazon will release an eighth-generation "all-new, top of the line Kindle" next week. There's no word on pricing or when it will be available.

On Monday, Amazon also began heavily discounting its current line of Kindles. The discount is only available for Amazon Prime members, who can get a Kindle for $50, a Kindle Paperwhite for $90, and the Kindle Voyage for $150.

Further, the Wall Street Journal notes that Amazon is developing a solar-charged Kindle case within its Lab126, the hardware unit of Amazon, though it's not expected to be released in the immediate future.
