Dr. chem. Gunārs Bajārs (born 1957) is a prominent Latvian materials chemist and leading researcher at the Institute of Solid State Physics, University of Latvia (ISSP UL). His career spans decades of pioneering work in electrochemical energy storage, with a focus on battery materials for lithium- and sodium-ion systems. Joined ISSP UL early in his career, contributing significantly to electrochromism, electrochemical sensor and battery materials research. Steered the Solid-State Ionics Laboratory before initiating the Laboratory of Materials for Energy Harvesting and Storage. Brief tenure as Rector of Vidzeme University of Applied Sciences, where he expanded tourism programs, though he soon returned to his scientific passion . Specialized in developing lithium-ion battery materials, aiming to improve capacity, safety, and reduce size—particularly important for electric vehicles Pioneering research into fourth-generation solid-state batteries using solid electrolytes, addressing liquid electrolyte drawbacks like flammability and weight . Explores sodium-ion batteries as an affordable, abundant alternative for stationary energy storage, suited to solar and wind applications . Co-developed a cutting-edge method for applying thin-layer lithium iron phosphate coatings, recognized as the Latvian Academy of Sciences’ most significant achievement.
