Despite the progress made by commercially available lithium ion (Li-ion), advanced lead-acid, flow, and molten salt batteries, the path toward the commercialization of new battery chemistries continues. Several new advanced battery chemistries are projected to become commercialized in the coming years. Meanwhile, motive transportation energy storage needs will be met by commercially available Li-ion batteries during the next decade. The majority of batteries for grid-tied stationary energy storage will be Li-ion, along with a mix of advanced lead-acid, flow, and sodium sulfur (NaS) batteries. Sales growth for pre-commercial next-generation advanced battery (NGAB) chemistries in both sectors is not expected to accelerate until 2021-2025. Lithium solid-state (Li-SS) is anticipated to be the first new battery chemistry for the transportation sector, and advanced flow batteries will likely be the first new technology for the stationary energy storage sector. Companies working to commercialize NGAB technologies that partner with well-funded Li-ion battery technology companies and energy companies will be at a strategic advantage. Navigant Research anticipates that those that show progress toward commercialization will likely receive investment or will be acquired by the current leading Li-ion companies. In 4-6 years, these established Li-ion battery technology companies will be well-positioned to add technologies to their manufacturing, supply chain, and sales channels. This Navigant Research Leaderboard Report examines the strategy and execution of 12 leading battery companies that are commercializing NGABs for motive transportation and grid-tied stationary energy storage, including lithium sulfur (Li-S), Li-SS, next-generation flow, and liquid metal batteries. These players are rated on 12 criteria: vision; commercial go-to market strategy; partners; commercial production strategy; technology; geographic reach; commercial plan execution; commercial product performance; commercial product quality; commercial product portfolio; pricing; and staying power. Using Navigant Research?s proprietary Leaderboard methodology, vendors are profiled, rated, and ranked with the goal of providing an objective assessment of their relative strengths and weaknesses in the global NGAB market.
