摘要： The present invention relates to a solid electrolyte including Li, O, P and a transition metal element. In the solid electrolyte, because the transition metal element T is reduced prior to phosphorus atoms, it is possible to prevent the valence of phosphorus atoms from decreasing. Thereby, the decomposition of the solid electrolyte resulting from the decrease of valence of phosphorus atoms is prevented, and therefore high ion conductivity is retained even in a wet atmosphere.
摘要翻译： 本发明涉及包含Li，O，P和过渡金属元素的固体电解质。 在固体电解质中，由于过渡金属元素T在磷原子之前还原，所以可以防止磷原子的化合价降低。 由此，能够防止由于磷原子的价态的降低导致的固体电解质的分解，因此即使在湿气氛中也能够保持高的离子传导性。
