Web13 apr. 2024 · The Lawsuit. On April 12, 2024, a plaintiff shareholder filed a securities class action lawsuit in the District of Delaware against Plug Power and certain of its directors and officers. The complaint purports to be filed on behalf of investors who purchased securities of Plug Power between August 9, 2024, and March 1, 2024. The lattice distance between silicon atoms multiplies as it accommodates lithium ions (lithiation), reaching 320% of the original volume. The expansion causes large anisotropic stresses to occur within the electrode material, fracturing and crumbling the silicon material and detachment from the current collector. Prototypical lithium-silicon batteries lose most of their capacity in as few as 10 charge-discharge cycles. A solution to the capacity and stability issues posed by the significa…
